ZW32-12 Medium Voltage High Voltage Outdoor Vacuum Circuit Breaker
The circuit breaker adopts a fully closed structure with good sealing performance, which is helpful to improve the moistureproof and anticoagulation properties, especially suitable for use in cold or wet areas.
The 3, 3-phase pillar and current Transformer adopt imported epoxy
resin solid insulation, or use indoor epoxy resin outsourcing
silicone rubber solid insulation; It has the characteristics of
high and low temperature resistance, UV resistance and aging
resistance.
The operation mechanism adopts a miniature spring operation
mechanism, with low power and low energy consumption of power
storage motor. The mechanism transmission adopts the real
transmission mode, with small number of parts and high reliability.
The operation mechanism is placed in a sealed mechanism box, which
solves the problem of rust and improves the reliability of the
operation mechanism.
The circuit breaker is generally composed of a contact system, an arc extinguishing system, an operating mechanism, a unbuckling device, and a housing.
Classification:
It is divided into high voltage circuit breaker and low voltage
circuit breaker according to its use range . A switching device
capable of breaking and carrying current under normal loop
conditions and of carrying and breaking current under abnormal loop
conditions within a specified time.
It has the function of overload, short circuit and undervoltage
protection, and has the ability to protect the line and power
supply.
