JYN1-35(F)AC metal sealed and movable switch board (in the following we call switch board ) is a type of metal sealed switching equipment for interior device using three phases and 50hz frequency AC it can be used in power plant as well as on distribution equipment complex of single bus or single bus segment whose system rated voltage is 35kv, the maximal rated current is 1000A and the highest voltage does not exceed 40.5kv in transformer room ,this type of switchboard has "five prevention" function :breaker for preventing operation by mistake preventing lord’s pushing or pulling lorry ,preventing attachment to earth with electrical preventing feeding earth connection and preventing entering electric gap by mistake.
Model No.
Technique data
The primary element assembled on the switch board includes lack oil circuit breaker or vacuum breakerfunction mechanism current mutual inductor ,voltage mutual inductor fuse ,lightning arester ,electric powertransformer and so on ,on the condition that the equipment has ,these elements should have their owntechnique characters.
