Cheapest Factory Works Like Champ Vs1 12kv Handcart Type High Voltage Vacuum Circuit Breaker Vcb

Short Description:

VS1-12 series solid-sealed indoor vacuum circuit breaker is an indoor high-voltage switchgear for three-phase power system with rated voltage of 12kV and frequency of 50 Hz. It is used as protection and control appliance due to vacuum circuit breaker. The special advantages are especially suitable for frequent operations requiring rated current or multiple short-circuit currents.

VS1-24 series solid-sealed indoor vacuum circuit breakers are fixedly mounted, mainly used for fixed switchgear. The circuit breaker can be used alone or in ring power supply, box transformer or various non- power supply system.

Overview

ZN85-40.5 series indoor high-voltage vacuum circuit breakers(hereinafter referred to as circuit breakers) are suitable for three-phase AC 50Hz power system with rated voltage of 40.5kV,and can be used for industrial and mining enterprises,power plants and substation to sparate load current,overload current and fault current.The circuit breaker and the operating mechanism are arranged up and down,which effectively reduces the depth of the ciecuit breaker.

The three-phase are extinguishing chamber and the associated electrified body are separated by three independent epoxy resin insulation cylinders to form a composite insulation structure.The circuit breaker meets the requirements of air distance and climbing distance under normal operation conditions.and effectively reduces the size of the ciecuit breaker.The vacuum interrupter of the main conducting circuit and the dynamic and static conductive connection are installed in the insulation cylinder,so that the phase spacing is only 300mm.The main circuit electrical connections are all fixed connections with high reliability.The insulation cylinder is installed above the breaker frame.

The spring operating mechanism specially designed for this new type of circuit breaker is installed in the frame of the corcuit breaker,and its structural characteristics are more suitable for the up-and down arrangement of the circuit breaker,and become an integral part of the whole word structure of the circuit breaker0The mechanism design is simple,and the output curve and its performance are more suitable for the characteristics and requirements of 40.5kV vacuum circuit breaker.
