ZN85 40.5kv indoor HV vacuum circuit breaker mechanical switch for 40.5KV Switchgear Draw-out VCB 1250A-2500A handcart KYN61
ZN85-40.5 indoor high-voltage vacuum circuit breaker is an indoor high-voltage switchgear with a rated voltage of 40.5kV and three-phase AC 50Hz. The circuit breaker is a handcart structure and can be used in conjunction with KYN61-40.5 switchgear. The circuit breaker is equipped with a reliable interlocking unit to meet the "five prevention" protection functions of users. The related supporting products include: isolation handcart, fuse handcart, fuse with lightning arrester handcart, and PT handcart. The circuit breaker adopts a composite insulation structure to meet the insulation requirements under normal operating conditions. And effectively reducing the volume of the circuit breaker, the overall layout is reasonable, beautiful, and concise. The operating mechanism adopts a specially designed spring operating mechanism, and the output curve matches well with the requirements of the arc extinguishing chamber. Its performance is more suitable for the characteristics and requirements of 40.5kV vacuum circuit breakers, with high reliability, long service life, convenient maintenance, and maintenance free mechanism. The circuit breaker handcart adopts a screw nut pushing device with an overrunning clutch, which can easily move the handcart in the switchgear, making the handcart travel range precise and reliable; Equipped with a mandatory mechanical locking method to meet the "five prevention" functional requirements of the switchgear.
