The Advantage of Power Transformer

Power transformers are one of the main equipment for power plants and substations. The role of the Farady 50 kva power transformer is not only able to raise the voltage to the electricity area, but also to reduce the voltage for the use of voltage at all levels to meet the needs of electricity. In short, the boost and buck must be done by the Farady transformer. In the process of power transmission of the power system, there will be two parts of the voltage and power loss, the same power in the transmission voltage and voltage inversely proportional to the power loss and voltage inversely proportional to the square. The use of transformers to improve the voltage, reducing the transmission loss.

pole mounted transformers in extensive rural area

pole mounted transformers are used in extensive rural area. These polemounted transformers range from 3kva transformer to 167kVA transformer and transform 11,000 to 33,000 volts down to a low voltage of 400 volts. Pole mounted transformers (50 kva pole mount transformer)are reasonably small in size and mass so that it is easy to install them on single pole structures, and larger units on two-pole structures, approximately 5 meters above the ground. This makes the pole mounted transformers inaccessible, reducing the risk of injury to animals and people and minimizing vandalism.

Oil-immersed transformers to a energy saving and environmental protection

Oil-immersed transformers are a relatively traditional electrical equipment, especially in the use of oil-immersed transformers for economic development has an important role, and thus for the industry is advancing with the times, oil-immersed transformers The oil-immersed transformer (50kva power transformer)oil is also constantly improved, mainly to improve the use and quality, making the oil-immersed transformer work more smoothly, improve efficiency. And with the development of the market and the needs of social development for the oil-immersed transformer industry is also toward the direction of energy-saving development. So for oil-immersed transformers in terms of oil is constantly improving, toward a more energy-efficient and environmentally friendly direction to develop!

In the view of some experts, the use of traditional mineral oil oil-immersed transformer oil, oil type transformer and other electrical equipment may not be in the short term failure, but there may be risks in the long run. Some substandard oil-immersed transformer oil is corrosive sulfur caused by oil-immersed transformer winding burn failure, causing the direct cause of the accident for the choice of oil-immersed transformer oil improper. Some oil-immersed transformers after about 10 years of operation, the oil-immersed transformer oil contained in the sulfur will lead to oil-immersed transformer breakdown burned, resulting in improper selection of oil-immersed transformer oil caused by the accident.

It is understood that the base oil of oil-based oil does not contain sulfur, can be practical application of sulfur caused by the corrosive problem to a minimum. At the same time, gas production of low-temperature performance better, in the winter in Harbin can be used normally. In addition, the oxidation stability of gas oil has a significant advantage, can effectively extend the service life of oil, flash point of 191 degrees Celsius, a substantial increase in safety standards, and oil consumption is significantly reduced by nearly 25%, protection of oil-immersed transformers Equipment safe, durable and efficient operation.

About power transformer for you

A power transformer (50kva power transformer)is a passive electromagnetic device that transfers energy from one circuit to another circuit by means of inductive coupling. Power transformers differ from other transformer types in that they are designed to comply with regulatory requirements for mains power interfacing, working at mains voltages and relatively high currents. The most important specification of a power transformer is its primary to secondary transformer galvanic isolation, which is usually specified in kV. This is a fundamental safety aspect in protecting humans from potentially lethal earth fault conditions.Dry power transformers typically have a single primary (mains side) winding and one or more secondary windings. The secondary winding may be tapped at different points to generate multiple voltage outputs. A power transformer operates according to Faradays Law of Induction. A transformer’s secondary voltage is equal to the negative rate of change of the magnetic flux enclosing the circuit. The magnetic flux enclosing the secondary circuit is caused by the AC flowing in the primary winding. This AC generates a changing flux that couples through a common core into the secondary winding. Voltage ratio is equivalent to the winding turn ratio. Transformers are extremely efficient when operating within their design specifications. Core type is an important consideration. Typical power transformer supplies include: laminated core, semi-toroidal and toroidal. Laminations can be important as they help prevent eddy currents flowing in the core that cause loss of efficiency. Maximum output current is specified at the point where the core is saturated or the windings current rating is exceeded. There are many mounting options including: chassis mount, DIN rail, wall mount and PCB mount. Terminations can be solder lugs, wire leads and terminal blocks. Galvanic isolation is typically rated between 1.5kV and 5kV. Power transformers are found in any application that requires mains power. They are also used as 1:1 isolating transformers for equipment safety. 120-240V transformers are also available for conversion between mains standards.

How to solve the problems in power transformer?

1. the weld is leaking oil

Mainly the welding quality is bad, there is Weld, desoldering, weld pinhole, trachoma and other defects, the dry power transformers factory due to welding and paint cover, after the operation will be exposed to hidden dangers, the other due to electromagnetic vibration will make Welding crack, causing leakage. For the phenomenon has been leaking, first find out the leakage point, not missing. For the serious parts of the leakage can be used flat shovel or sharp red and other metal tools will be leaking point riveting, control the amount of leakage after the treatment of clean surface, most of the use of polymer composite materials for curing, curing can be achieved after long-term treatment The purpose of leakage.

2. seal oil leakage

Seal bad reasons, usually box along with the lid of the seal is the use of oil-resistant rubber rods or rubber pads sealed, if the joints are not handled properly will cause leakage of oil failure. Some with plastic banding, and some directly to the two ends of the pressure together, because the installation of rolling, the interface can not be crushed, not the role of sealing, or oil leakage. Can be used for the blessing of blue material bonding, so that the overall shape of the joints, oil leakage phenomenon is a lot of control; if the operation is convenient, you can also metal shell bonding, to achieve leakage management purposes.

3. flange connection leakage oil

Flange surface uneven, fastening bolts loose, the installation process is not correct, so that bolts fast, and cause leakage of oil. The first loose bolts for fastening, the flange sealing treatment, and for the possible leakage of the bolts are also processed to achieve the purpose of complete governance. The fastening of the loose bolts must be carried out in strict accordance with the operating process.

4. the bolt or pipe thread leaks the oil

Factory rough processing, poor sealing, 50kva power transformer seal after a period of time will produce leakage oil failure. The use of polymer materials to seal the bolt to achieve the purpose of governance leakage. Another way is to pull the bolt (nut), the surface coated with blessing blue release agent, and then in the surface after the application of material tightening, curing can be achieved after the purpose of governance.

5. cast iron oil leakage

The main reason for the leakage of oil is caused by sand and cracks in the cast iron. For crack leakage, drill hole is the best way to eliminate stress to avoid extension. Governance can be based on the case of cracks in the leak into the lead wire or hand horn riveting. Then use acetone to clean the leaks and seal with the material. Casting trachoma can be directly sealed with the material.

6. radiator oil leakage

Radiator heat pipe is usually made of stitched steel pipe after the stamping made in the cooling pipe bending part and welding part often produce leakage of oil, because the stamping heat pipe, the outer wall of the tube by the tension, the inner wall of the pressure , Due to the presence of residual stress. The radiator up and down the flat plate valve (butterfly valve) closed, so that the radiator oil and box oil cut off, reduce the pressure and leakage. To determine the leakage site after the appropriate surface treatment, and then use the blessing blue material for sealing treatment.

7. porcelain and glass oil oil leakage oil

Usually due to improper installation or seal failure. Polymer composite materials can be a good metal, ceramics, glass and other materials for bonding, so as to achieve the basic treatment of oil leakage.

Power transformer

When the 50kva power transformer transmitted power exceeds around 10 MVA, special designs are required to cope with the mechanical forces of short circuit currents, higher insulation levels and increased cooling requirements. For these ratings, liquid-filled transformers are usually used. The insulation between the windings becomes more and more demanding at higher voltages. Furthermore, resonance effects inside the winding itself have to be considered to avoid insulation failures during highly dynamic impulse stresses such as lightning strikes which may reach amplitudes of one to two thousands kilovolt with a 1 μs rise time.power transformer 10kva are a key element in the supply of large regions or industrial areas. As a rule of thumb, it can be considered that one person has an average electrical power demand of 1kVA, which means, that a 400 MVA transformer transfers the power needed by 400,000, the equivalent of a medium sized city. Such transformers have to comply with special requirements on safety and reliability and also have to provide a very high efficiency and low sound level. In recent decades, high voltage DC lines have also become increasingly important, especially in large countries such as China where they connect  industrial centers to the remote regions where the electricity is generated.

Series reactor (hereinafter referred to as series resistance) is a parallel capacitor device (hereinafter referred to as the capacitor device or capacitor group) is one of the main components, which plays a limit capacitor bank (back to back) closing surge in power harmonic suppression, to prevent the capacitor Damage, and to avoid the capacitive device access to the harmonic harmonic over-amplification and resonance and so on an important role.However, string resistance and capacitor can not be arbitrarily combined, if not consider the capacitance device access to the actual situation of the grid, the "one size fits all" (Such as capacitors are equipped with a reactance of 5% to 6% of the string resistance), often counterproductive, leading to a serious amplification of harmonics and even resonance, endanger the safety of devices and systems.Because of the presence of oil immersed distribution transformer harmonics The complexity and randomness of the capacitive devices, and the difference of the structure and characteristics of the electric network in which the capacitive devices are located make the choice of the harmonic response and the series reactance rate of the capacitor devices a difficult problem and a research topic. However, with the deepening of the research work and the accumulation of practical experience, many consensus opinions or effective measures have been put forward, or some suggestions have been made for the design of string reactors in the design of capacitor installations. Lessons Learned. The string resistance has both the advantages of suppressing inrush current and harmonics, but also has its additional power loss and construction investment and operating costs of the shortcomings.Therefore, the new expansion of the capacitor device, Or has been put into operation of the capacitor device in the series of anti-selection program, the technical and economic comparison is necessary.This paper focuses on the part of the capacitor device engineering design followed the choice of 6% string anti-problem analysis, with a view to device construction and Operation has some benefits.

Transient Effect of Magnetic Saturation on Transformer

Magnetic saturation transient effect of the transformer Note that magnetic flux should be checked for saturation near minimum input voltage and maximum pulse width. As the input voltage is high, the pulse width will be narrowed, so the core is far from saturated. In a transient load, when the input voltage is high and the load current is small, if the load current suddenly increases, the control circuit immediately increases the pulse width to provide the supplemental power. In this way, the input voltage and pulse width are simultaneously maximized, even if for a short period of time, the single phase step down transformer will appear saturated, and cause out of control and failure. Here are some measures to avoid runaway. (1) transformer in accordance with high input, voltage, wide pulse design, the core work in low flux density and winding more primary winding. The disadvantage of this method is to reduce the efficiency of the transformer, increasing the size of the Amorphous Core Transformers weight. (2) the control circuit should be in the high sensitivity to determine the state of work, when the high input voltage appears to be able to quickly limit the pulse width, it is still safe value. (3) in the control circuit to improve performance, so that the switch in the current work cycle to quickly respond to control. UC1846 / UC1847 current mode control chip, can automatically achieve this limit action.
