Substation

Transformer for Substation

The transformer is the heart of the substation. The transformer changes the relationship between the incoming voltage and current and the outgoing voltage and current. Power transformers used in substations are rated by their primary and secondary voltage relationship and their power carrying capability. For example, a typical substation transformer would be rated 69-13 kV and 20 MVA; meaning the primary or high voltage is 69 kV, the secondary or low voltage is 13 kV and the transformer has a power rating of 20 MVA or 20,000 KVA. Substation transformers, like most utility transformers, consist of a core and coils immersed in oil in a steel tank. The oil serves both as an insulator and as a coolant to keep the core at reliable operating temperatures.

Transformers Application

 Transformer for Hydroelectric Power Stations

The hydroelectric power plant generates the energy, but the electricity that is generated isn't the correct voltage to power people's homes. This is where electrical transformers come in. The electrical transformer converts the alternating current that the hydroelectric power is generating into a high voltage current. This converted power supply that is coming from the transformer in hydro power plant is connected to the national grid, where it is then distributed for domestic and industrial use.

Wind Power Box Type Booster Station

ZGS-ZF- -/35 combined transformer station includes step up transformer, high voltage current- limiting fuse, load switch and LV switch and corresponding axiliary device. Wind power box type bootster station generates electricity 0.69kV wind turbine voltage increasing to 35kV, transmitting the 35kV voltage by the cable, which is ideal for wind power generation system.

 Benefits of Wind Power Box Type Booster Station

Rich and Reasonable Layout

Photovoltaic, wind power box type booster station, the system layout is reasonable, compact, including low-voltage inlet cabinet, transformer and high-voltage outlet cabinet three parts, respectively installed in three separate rooms, "eye" font or "L" font layout, function is perfect, easy to maintain; Telecontrol devices and power transformers are installed in the low-voltage room to realize telecontrol control of box transformer and self-supply of box transformer, so as to meet the requirements of photovoltaic and wind power generation systems.

 High Safety

When the transformer radiator is installed in an open type, it realizes the completely natural ventilation cooling performance, saves a lot of power loss caused by forced ventilation, and eliminates the defect that the fan performance brought by forced ventilation is unreliable and easy to overtemperature tripping. In addition, the charged body is completely sealed in the box transformer to solve the dust protection problem. "Five prevention" function is complete, operation and maintenance is convenient, according to the need to meet the requirements of maintenance and repair in rainy days.

 Small Space

The high voltage load switch is installed in the transformer oil tank, and the box transformer is arranged in the shape of "L" and "eye". The low voltage room is equipped with telecontrol device and power transformer to realize the telecontrol control of the box transformer and the box transformer self-supply. Because there is no transformer room, the machine occupies a relatively small area, the machine cost is lower, and the user investment is reduced.

 Easy to Replace

"目" font layout, low voltage room set up remote devices and power transformers, realize the remote control of box transformer and box transformer power supply. The isolation knife of 35kV high voltage switch is placed in a separate room with the fuse assembly, which solves the problem that the entire circuit needs to be cut off when the fuse or arc extinguisher is replaced by the general switch.
