CD17 series is mainly applied to ZN28-12 series Handcart-type indoor high voltage vacuum circuit breaker can also be used other circuit breaker of frequent operation.
CD17A-type is mainly applied to various fixed type switchgear and used for ZN28A-12 sub-mounted indoor high voltage vacuum circuit breaker.
Above two series actuator use DC power supply, with indoor vacuum circuit breaker can be electrical ON-OFF, manual ON-OFF, remote control and automatic re-closing operation, and with free tripping function.
1. The coil of Mechanism is short time duty type.
2. The reliable closing voltage is rated working voltage 85%~110%. The reliable opening voltage is rated working voltage 65%~120%. Mechanism didn’t opening when rated working voltage <30%.
3. Duiring Conductivity part and earth part, during each conductivity parts of different loop, 1min Frequency voltage 2000v no appearance of flashover and breakdown. During the coil can resist 2.5times rated operate voltage.
4. The putout shaft of Mechanism’s working degree is about 51°, and the mechanical life is 10000times.
