Farady 500kva power transformer

farady 500kva power transformer has a notable feature large capacity, and the power to follow the principles of building a modest advance in economic development, in the past over-capacity operation of the transformer and rare. However, in recent years with the rapid development of national economy, the power supply and the load tends to be centralized, large-scale increase 500kV farady oil immersed power transformer capacity operation. Because of the large oil immersed power transformers, high cost, large capacity, wide supply range and impact is large, there is a big risk of capacity. farady transformer capacity convenient ability to run traditional search load table method to obtain fast, but for different parameters heat high pressure, high-capacity viewing results immersed power transformers for inaccurate, is not conducive to running the risk of capacity in advance of such transformers of an accurate assessment. Operating personnel by monitoring transformer hot spot temperature to determine their ability to run, albeit capacity, but are afterwards control, does not comply with the principle of pre-control risk. It is necessary according to the temperature rise test data on the capacity to run a large capacity 500kV oil immersed power transformers were calculated and analyzed, so as to achieve effective control of the power grid risks and safeguard supply security purposes.

Two kinds of transformers

Farady dry type transformer are usually used indoors, fire safety requirements are relatively high occasions. Oil filled transformers are usually outdoors, of course, can also be used indoors, farady oil immersed transformer failure might fuel injection and combustion, so indoor use more dangerous. Dry Transformers usually not spontaneous, high-quality products with flame retardant capabilities. Dry type transformers advantage is safe, clean, the disadvantage is the high price, accounting for a large area, outdoor use difficult; oil immersed transformers advantage is the voltage level can be very high, accounting for small size, wide range, the disadvantage is oil spills, pollution of the environment when failure. Two kinds of transformers follow different standards, different temperature requirements, the thermal performance of different structure is unfair. Structurally speaking, oil immersed transformer Good heat dissipation device.

The economic value of the farady transformer

china electrical transformer is one of a large number of electrical equipment used in power system. When the transformer in its internal loss while generating active and reactive power losses. Which is used to compensate for hysteresis and eddy current losses in the core of the core power loss, the establishment of the necessary magnetic field excitation transformer reactive power loss, the loss of two transformer is fixed load-independent. Regardless of the user with no electricity, with or without load, as long as a transformer connected to the grid, it will have the presence of iron loss and excitation loss, and spend out some active and reactive power, especially in the lack of working 24 hours a day or for a long time low load operation of the transformer, causing a waste of such a no-load power consumption is more prominent. Thus reducing this part of the loss has very important significance. Rural power grid load has a strong seasonal, diurnal changes, load distribution, utilization is low, and irrigation during the busy season, it may appear the phenomenon of overload, while in the slack at night And non-irrigation season, in addition to processing agricultural products to pay, daily electricity, very little electricity, most of the long-term is unloaded transformer, causing part of the power consumed in vain, resulting in waste of electricity. In order to solve the rural grid distribution
Transformer no-load operation of the long-term problem, to reduce power consumption, save energy, bringing more intense power be fully rational applications, we developed the "agricultural automatic stop transmission transformer high energy-saving devices", which means The transformer having a no-load automatic power from the high pressure side, high voltage electrical load automatically when feeding performance, eliminating transformer no-load power consumption, improve the power factor, improve voltage quality and reduce line losses. According to preliminary calculations,Each 50kva power transformer can power about a year of electricity over two thousand three hundred degrees.

Pad-mounted transformers for distribution systems

10kva single phase transformer, generally used in the USA system, are attached to the overhead wires with two different types of connections:If a primary neutral wire is available, a 'wye' or 'phase to neutral' transformer can be used. This usually has only one bushing on top, connected to one of the primary phases. The other end of the primary winding is 'grounded' to the transformer's case, which is connected to the neutral wire of the 3 phase system, and also earth ground. Pad-mounted transformers have secure locked and bolted grounded metal enclosures to discourage unauthorized access to live internal parts. The enclosure may also include fuses, isolating switches, load-break bushings, and other accessories as described in technical standards. Pad-mounted transformers for distribution systems typically range from around 100 to 2000 kVA, although some larger units are also used.

Distribution transformers normally have ratings

Distribution transformers normally have ratings less than 200kVA electrical transformer, although some national standards can describe units up to 5000 kVA as distribution transformers,but with the same effect 2000 kva transformer of Farady。Since distribution transformer is energized for 24 hours a day (even when they don't carry any load), reducing iron losses has an important role in their design. As they usually don't operate at full load, they are designed to have maximum efficiency at lower loads. To have a better efficiency, voltage regulation in these transformers should be kept to a minimum. Hence they are designed to have small leakage reactance.

electric power distribution system

A distribution transformer is a transformer that provides the final voltage transformation in the electric power distribution system, stepping down the voltage used in the distribution lines to the level used by the customer. The invention of a practical efficient transformer made AC power distribution feasible; a system using distribution transformers was demonstrated as early as 1882.If mounted on a utility pole, they are called single phase pole mounted transformers. If the distribution lines are located at ground level or underground, distribution transformers are mounted on concrete pads and locked in steel cases, thus known as pad mounted transformers.

Prospects dry-type transformers


Dry-type transformers have developed rapidly over the world, the time to be traced back to the late 20th century, so far only half a century. With the development of China's modernization, and rural power grid load is increasing. The 1990s, dry-type transformers can be widely applied in our country. With the pace of large urban and rural power grid construction and transformation of the western development to accelerate, the success of Beijing's bid for the 2008 Olympic Games, the Three Gorges water conservancy project starts generating power, dry-type transformers are facing new opportunities for development, production and sales which will have a new leap forward.

Recently, articles on dry-type transformers trends seen in various newspapers, the study of technology, process of discussion of the development of dry-type transformers are very useful. In this way, we also talk about some of the views.

With dry-type transformers continuous innovation in our country and promote the use of a large number of domestic design and manufacturing technology has reached world-class level, the future of dry-type transformers are expected to gain further development.
Our losses in the manufacturing and research and energy saving transformer noise, has made gratifying achievements, with a high level. However, environmental protection is the eternal subject of transformer research and development, there are many issues worthy of study. The introduction and development of low-loss silicon steel, in-depth step ladder laminated core seams, foil winding structure, noise studies, environmental requirements, computer optimized design, new materials, new processes, new technology will enable future dry more energy-efficient transformers more quiet. However, simply relying on material inputs to reduce iron loss or copper loss, or noise, we believe that are not desirable.
