Product Description
Permanent magnetic Medium voltage and high-voltage vacuum circuit breakers
The ZN73F-12 vacuum circuit-breaker is suitable for indoors type switching system which taking the air as the insulation. In the normal working condition and in circuit breaker's technical parameter scope, the ZN73F-12 vacuum circuit breaker can meet each kind of operation at the electrical network normal or abnormal condition, including switch on and switch off and braking current. Under the situation of frequent operation or needs to open breaking the short-circuit current, it will have the extremely fine performance and satisfythe requestment of switch on or switch off automatically and has the extremely high operation reliability and the service life.
The permanent magnetic actuator produces the driving force.
The permanent magnetic actuator realizes the release.
Low quantity of components
High reliable
Few maintenances
The permanent magnetic actuator realizes the locking.
Simple structure, low noise, free of maintenance.
Simple operation process
Long service life
Application:
Thermoelectricity Chemical industry Water conservation Mining Construction Metallurgy Electric pow
Main performance characteristic:
1. Improve vacuum circuit-breaker whole mechanical function, suit for frequently switching on or off and requirement of long life. Vacuum circuit-breaker mechanical life is more than 10.0000times.
2. Compare with traditional actuator, no need mechanical the device of lock and unlock, reduce large number of components, only one component moving for working, reduce fault, low maintenances
3. The feature of actuator conforms the feature of arc-extinguishing chamber switching on or off, in this way, extend the life. Of arc-extinguishing chamber.
4. Adopt high reliable and double stable control mechanism structure design. Through switching on/off coil produce the magnetic force to control the operation of switch on/. Off, the positions of on/off is kept by permanent magnetic.
5. The combination of permanent magnetic material and coil of switching of on/off solves the problems of large power energy needed by switching off. The speed of manual switching off and electric switching off shall be same to make the breaking short current more reliable.
6. Prevent jumpping function and design of flexible connection and contact auxiliary spring to solve the problem of switching on bounces.
7. Adopts intelligence control and liquid-crystal display, indicates all of kinds working condition of circuit breaker. At same time, it also have the alarm function of low voltage refused switching on.
8. AC and DC energy stored operation, after no power within 2hours, it can be operated for each one time of switching off, switching on and switching off.
9. Reliable operation control circuit module for tolerance of the lighting strike, surge and other bad condition. Permanent magnetic material adopts NdFeB, the magnetic feature shall reduce 0.5‰ After every 100 years
10. This circuit-breaker have free repair, easy to maintain, easy maintenance, no pollution, anti explosion, low noice, suitable for frequent operation and worse working conditions.
