Five anti-latching switchgear 3.6, 7.2, 12kV

Fixed metal enclosed switchgear (referred to as switchgear). Used for 3.6, 7.2, 12kV three-phase AC 50Hz series as the acceptance and distribution of electrical energy, especially suitable for frequent operation occasions, the bus system is a single bus.

General:

The switchgear conforms to the requirements of national standard GB 3906-2006 "3.6kV-40.5kV AC metal enclosed switchgear and control equipment" and international standard IEC62271-200, and there are two proposed "five" blocking functions. The main switch of this switch adopts VS1-12 connected operating mechanism series vacuum circuit breaker, and the isolation switch adopts GN30-12 rotary isolation series products.

Service Environment

Ambient temperature: upper limit +40℃, lower limit -25℃;
Altitude: The altitude does not exceed 1000m;
Relative temperature: the daily average is not more than 95%; The monthly average is not more than 90%;
Earthquake intensity: not more than 8 degrees.
Surrounding environment: no fire, explosion danger and pollution level does not exceed 3, chemical corrosion and violent vibration places

Key Feature

The circuit breaker room is also provided with a pressure release channel, if the internal arc occurs, the gas can be released through the exhaust channel
The switchgear adopts the corresponding mechanical interlock
