Description
IEC 12KV 1250A Metal Enclosed Switchgear For Power Plants
Scope of useedit
It is widely used in various substations of power systems, power plants, industrial and mining enterprises, and high-voltage power distribution.

Working environment
1. Air temperature: -25℃~+40℃
2. Humidity: Monthly average humidity 95%; Daily average humidity 90% .
3. Altitude: ≤ 2500m
4. Ambient air not apparently polluted by corrosive and flammable gas, vapor etc.
5. No frequent violent shake

Fully type-tested
The switchgear has undergone all the tests required by the international (IEC) Standards. Each switchgear unit is subjected to routine tests in the factory before delivery. These tests are intended to provide a functional check of the switchgear based on the specific characteristics of each installation.

"Five Preventions" of High Voltage Switchgear
1. After the vacuum circuit breaker trolley in the high voltage switch cabinet is closed at the test position, the trolley circuit breaker cannot enter the working position. (Prevent closing with load)
2. When the grounding knife in the high-voltage switch cabinet is in the closed position, the trolley circuit breaker cannot be closed. (Prevent closing with ground wire)
3. When the vacuum circuit breaker in the high-voltage switch cabinet is closing, the back door of the cabinet should be locked with the machine on the grounding knife. (Prevent the electrified interval by mistake).
4. The vacuum circuit breaker in the high-voltage switchgear is closed when it is working, and the grounding knife cannot be turned on. (Prevent the live ground wire from hanging)
5. The vacuum circuit breaker in the high-voltage switch cabinet cannot exit the working position of the trolley circuit breaker when it is working and closed. (Prevent load broach)
