What is the significance of the substation?

A substation is a type of high voltage switching system, a distribution transformer and a low voltage energy distribution device. It is a compact power distribution system for the inner and outer areas, pre-fabricated on the factory side, arranged according to a specific wiring scheme. Combined, the substation is installed in a moisture-protected, rust-free, dust-tight, nail-resistant, fire-resistant, theft-resistant, heat-insulating, fully closed and drivable steel case, which is particularly suitable for urban network construction and conversion, A new type of substation is created after the civil substation.

What are the characteristics of substations?

The transverse station has a strong overload capacity which allows a double overload for two hours and a 1,6-fold overload for seven hours without affecting the life of the box change.

The substation uses an angle connector, which can be very convenient for connecting high voltage input cables and can be used in emergency situations as a load switch, which can be plugged and plugged under current.

The retractor has a double safety guard, and the plug-in (BAY-o-net) is a double sensitive safety (temperature, current) to protect the short circuit failure occurring on the secondary side of the box transformer. The forward current protection system (ELSP) protects the internal defect of the box transformer and serves to protect the upper voltage side.

Transformers of power stations generally use high-ignition oil (FR3).

All components such as fuses for the protection of high voltage load switches are in the same oil tank as the transformer core and the windings.



What is the high voltage load switch of substation?

The load switch is put inside the substation. The oil-immersed three-phase linkage switch can be divided into two positions (terminal type) and four positions (ring network type). As this load switch is located in the transformer boiler, it can only be closed in accordance with the instructions of the external control panel and must be operated via a special isolated control bar, making its operation more complicated. From this point of view, its operation is very uncomfortable. Since the breaker contacts of the load switch (i.e. the obvious point of departure) are invisible, this also causes a feeling of fear after the break. In addition, it is very difficult to replace and repair it once the load switch of the transducer fails. The load switch generally uses a vacuum power switch.



What is the ZBW box substation?

The combined substation ZBW-10/0,4KV is a pre-installed complete switching equipment consisting of a high voltage room, a transformer room and a low voltage room. It is suitable for ring network, two-wire, terminal power supply mode, and the three modes have excellent interchangeability. Cables are used for the Wire-in process. The high pressure chamber has an absolutely reliable compact design, a comprehensive anti-malfunction locking function, high reliability and convenient operation and maintenance. The high voltage space is compatible with end-load switches, air ring switches, SF6 ring-network cabinets, etc. Saton transformers can use oil-dipped transformers and dry transformers. The transformer room adopts a temperature control and can accept above a natural ventilation or a forced ventilation. The low voltage chamber is equipped with measurement and power compensation. The secondary cycle and the number of outputs can be designed according to the needs of the user to meet different requirements.
