Summary
The intelligent prepaid vacuum circuit breaker on the ZW32M-12 series outdoor columns is rated current,12kV, and three-phase ac 50Hz outdoor power distribution equipment.It is mainly used to break the load current, overload current and short circuit current in the system.It is suitable for the protection and control in substation and industrial and mining enterprise distribution system, and the frequent operation of rural power grid.
Main features
1, the intelligent control function: the circuit breaker has a local switch state control, a three-stage over-current protection, three functions such as automatic reclosing. And RS - 485 communication interface can realize telemetry, remote adjustment, remote control, remote telecommunications, and other functions, suitable for all kinds of the size of the power distribution automation system.
2, permanent magnet operating mechanism: the broken chrome device adopts the most advanced permanent magnet jostle for institutions, organization does not wear parts, its mechanical life can reach 30000 times, is three times as many ordinary spring mechanism.Since the number of mechanical parts of permanent magnet mechanism is 70% lower than that of spring, the reliability of switch is greatly improved.
3, fully sealed structure design, the circuit breaker of the vacuum arcing chamber, operating mechanism and operating link fully sealed within the circuit breaker base, solve the condensation of circuit breaker parts to rust, the product can reach 10 years free maintenance.
4, the structure of the miniaturization, circuit breaker adopts new type of composite solid insulation materials, the vacuum arcing chamber, main electric circuit, insulation support and organically combined to become an integrated solid pole column, completely solve the vacuum arcing chamber is miniaturization and satisfies the requirement of external insulation.The whole product design is advanced and reasonable, the structure is compact, there is no condensation inside, the mechanism has no rust.
