Product Description

Medium Voltage Switch Cabinet

Product introduction: this product is shielded metal type of switch device which is suitable for electric system with 3 phases AC 50Hz, 7.2~12Kv single busbar and single busbar section, which have “5 prevention” functions. The removable part of the switch cabinet can be equipped with vacuum breaker and vacuum contactor, etc.

Application range: it is suitable for the control of hoister, conveyor, fan, air compressor and water pump in the place of non explosion-proof which control is high voltage power supply.

Using ambient:

1. Ambient temperature: ≤﹢40;

2. Relative moisture: 90%

3. Protection grade: IP20

Working principle: to control the connect and open of vacuum breaker and vacuum contactor though the Low Voltage control circuit, realizing the control of high voltage power supply for the main circuit.

Advantages and features:

① 5 prevention functions: preventing the on-load from opening and closing the disconnector. Preventing mis-opening and mis-connecting the breaker, on-load switch and contactor. Preventing the earthing switch from closing the breaker and on-load switch when it is on the position of close. Preventing mis-connecting the earthing switch when it is electriferous. Preventing mis-coming into the electriferous interval.

② Wide application: this product have been considered the influence caused by the reducing of air media strength when it is installed over 1000m.
