power transformers

power transformer 10kva is belonging to the power of power transformers, power transformer core material commonly used mainly iron, low silicon, high silicon steel sheet can be reduced by adding silicon steel sheet of conductive Resistance, increased resistivity, which reduces eddy current loss is reduced to make it. We are professional power transformer manufacturer, provides oil immersed power transformer, ac powertransformer,dry electric transformer, 50kva power transformer, 100kva power transformer, 500kva power transformer, dry power transformers for you, please join us.

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.

About Automatic voltage regulator systems

In order to control the generator output (for example, in ships, power plants, oil rigs or emergency power supply system), the automatic voltage stabilizer. Automatic voltage regulator systems are active, their action on the same principle and the general regulator, but the system is more complex. Automatic voltage regulator includes diodes, capacitors, resistors and potentiometers, and even includes a microcontroller, all placed on a circuit board. Usually installed near the generator, connect some lines with measurement and adjustment of the output of the generator. A step voltage stabilizer is designed to automatically maintain a constant voltage level. step voltage regulators may be a simple "feed-forward" design or may include negative feedback control loops. It may use an electromechanical mechanism, or electronic components. Depending on the design , it may be used to regulate one or more AC or DC voltages.

For the residential area distribution construction and renovation

For the residential area distribution construction and renovation, 10kva single phase transformer and distribution technology is mainly reflected the four basic features: (1) a power distribution room to 10kV distribution lines to residential building door house at the user; (2) single-phase transformer hanging rods, low-pressure Line (220V) power distribution into the household, then the family line length does not exceed 20m; (3) a reasonable selection of single-phase transformer capacity and residential buildings, the largest electricity power to match the formation of small-capacity dense point situation; (4) power meter centralized set in the residential floor corridor meter box suitable locations.

3 phase step up transformer

china electrical transformer basically follows the conventional pole transformer and distribution technology, along with the deepening of reform of power industry, especially in the study of the power grid to reduce line losses, improve enterprise efficiency process found that there are many shortcomings of a single low-voltage distribution way, line losses Great, while developed countries attach great importance to optimize the distribution voltage, residential, small commercial area hanging rods commonly used single-phase or 3 phase step up transformer transformer power supply from single-phase transformer consisting of 6kV or 10kV high voltage directly to the user; universal the use of small-capacity, dense point manner, thereby minimizing voltage lines, reducing line losses.
