KYN28A-12 Metal-clad enclosed switchgear Product Overview:
KYN28-12 switchgear is electric distribution equipment which apply to 3phase AC 50Hz, working current to 4000A system. It is used for power acceptance and distribution, circuit control, protection and inspection, etc in power plant, transformer substation or industrial and mining establishments. It can also be use in frequent operation place. It consists of cubicle and removable parts (hand cart). Cabinet is fabricated aluminum zinc-coated steel plate with bolt, and the cabinet is divided by metal plate into circuit breaker compartment, main busbar compartment, cable compartment and relay meter compartment. All metal parts are reliably earthing. Each compartment of main circuit system have pressure release channel.
KYN28A-12 Metal-clad enclosed switchgear Structure Feature:
1. Full metal-clad, assembled structure.
2. It complies with GB3906 & GB/T11022 & IEC60298 & DL/T404.
3. It can assemble with electrical equipment such as: Transformer and vacuum circuit breaker.
4. Each compartment is divided separately, high safety performance.
5. Compulsory mechanical locking method is employed in the interlocks among main switch, handcart and cubicle door to meet the five-proof interlock function.
6. The panel includes Hand cart location indicator and display unit, it features safety and reliability.
7. Vacuum circuit breaker: VS1VD4VSm(Permanent magnetic operation structure)
