Electrical Power Transformer Box Type Substation

Electrical Power Transformer Box Type Substation

Professional customized package substations, applicable to all parts of the world. The box type substation has 3 main compartments. There are transformer room, medium and high voltage switch cabinet room and low voltage switch cabinet room. The high-pressure and low-pressure rooms are fully functional.

The H.V. compartment has a variety of power supply methods when testing the power supply at a time, and H.V. testing equipment can also be installed to meet the needs of H.V. testing.

The transformer room can choose S7, S9, S11 or other low-loss oil-immersed transformers or dry-type transformers. The transformer room has an automatic start air cooling system and a lighting system.

The low-voltage room can be made according to user needs, using a fixed or assembled structure as the power supply system, with multiple functions such as light distribution, power distribution, reactive power, and power testing to improve power distribution. Quality and satisfy users.

The substation body can be made of metal materials, stainless steel materials, non-metal materials...according to customer requirements.

This substation is a very important power distribution and power supply unit in the cable grid. It is a complete power supply with HV control, protection, conversion, and power distribution. It is used for three-phase AC 50Hz and maximum rated current. 1600KVA transformer. It is widely used in industrial and mining enterprises, residential communities, hospitals, shopping malls, high-rise buildings and other power distribution systems.

For this substation, we mainly produce and export 11KV, 15KV, 20KV, 24KV, 33KV types.

For customized special types, once we obtain clear technical data or single-line diagram (SLD), we can also manufacture.

1、 Configuration of high-voltage side of box transformer

(1) The box transformer is divided into terminal type and ring network type based on the primary wiring method on the high-voltage side. The terminal type box transformer does not need to consider additional wiring: if the high-voltage side is one in multiple out or multiple in one out (mostly one in two out or three out, or two in one out or two out), it can be considered as a ring network type box transformer.

(2) European style box transformers have circuit breaker configurations on the high-voltage side, as well as load switch fuse combination protection. Considering the cost of box transformers, for box transformers with a capacity not exceeding 800 kV · A and low requirements for high-voltage side protection configuration, the latter is often used.

(3) The high-voltage load switches configured in European style box transformers are mostly FLN-12 sulfur hexafluoride load switches.

(4) The rated current of the high-voltage fuse melt for protection is selected according to the following formula:

Irr=KIgmax

In the formula, Irr - rated current of the melt, A; K - coefficient, generally taken as 1.3:

Igmax - Rated current on the high-voltage side of the transformer.

(5) Considering the safety of operation and maintenance, the high-voltage side configuration of European style box transformers should meet the following requirements.

① When the load switch is disconnected, there is a grounding device to ensure maintenance safety.

② The load switch and isolation switch ensure mutual locking to ensure safe operation.

(6) Due to the combination of high-voltage load switch and fuse, the American style box transformer is assembled in the same oil immersed box, including position load switch, backup fuse, plug-in fuse, and transformer. The ring network type is achieved by converting the internal connection terminals of the position load switch.
