Switchgear is a kind of electrical equipment, outside into the first master switch inside, and then enter the sub-control switch, according to the need for shunt. If the instruments, automatic control, motor magnetic switch, a variety of exchanges and contacts, etc., some of them set up high-pressure and low pressure chamber Switchgear room, equipped with high-voltage bus, such as power plants, and so on, there are also some security for major equipment-week low Load shedding.
The high voltage switchboard, "the five anti-"
The high voltage switchboard, "the five anti-"
1, high voltage switchboard of the vacuum circuit breakers in the test car position after the closing, the car entered the circuit breaker can not work location. (To prevent the closing load) 2, high voltage switchboard in the ground in the knife-Hop, car into the circuit breaker can not switch on. (To prevent the grounding line with closing) 3, high voltage switchboard of a vacuum circuit breaker in the closing hours of work, set the back door cabinet with a knife on the ground with mechanical locking doors. (To prevent charged into interval). 4, high voltage switchboard of a vacuum circuit breaker in the closing hours of work, with a knife can not be ground into. (Charged to prevent the ground wire attached) 5, the high voltage switchboard in a vacuum circuit breaker switch on the work of running car from the circuit breaker can not be the work of the position. (With negative zone to prevent the switch Hela)
Switchgear common:
1, taking the low-voltage switch cabinet 2, the exchange of low-voltage power distribution cabinet 3, metal-sheathed away Switchgear 4, separated by low fixed-Switchgear 5, high-voltage capacitors cabinet 6, high voltage switchboard |
