The invention discloses a vacuum
circuit breaker and a load switch. The vacuum
circuit breaker and the load switch solve the problems that in the prior art, the size is large, power supply continuity is poor, and the environment is polluted by SF6 gas. The vacuum
circuit breaker and the load switch comprise a mini-type modularized polar column and an operating mechanism. The vacuum circuit breaker and the load switch are characterized in that the polar column comprises a
vacuum arc-extinguishing chamber, a chain contact finger connecting base, a fixed contact, an electric conduction flexible connection and an insulation pulling rod, the
vacuum arc-extinguishing chamber, the chain contact finger connecting base, the fixed contact, the electric conduction flexible connection and the insulation pulling rod are packaged inside an outer shell insulation cavity, the operating mechanism comprises a polar column installation rack and a mechanism body, the part
standardization degree of the mechanism body is high, the mechanism is easily assembled, disassembled and replaced, the manual operation and the electric operation can be achieved by adjusting an
energy storage motor or a switch-on
electromagnet or a switch-off
electromagnet or an energy pre-storage switch-off spring or an energy pre-storage switch-on spring and replacing the parts like the
vacuum arc-extinguishing chamber, the conversion of switching on and switching off is completed, and the conversion of the circuit breaker and the load switch is completed. The vacuum circuit breaker and the load switch are compact in structure, reasonable in design, high in insulation strength and good in interchangeability, facilitate field installation and debugging, have the switch-on capacity and switch-off capacity of different breaking currents, can achieve the rapid and stable switching on and switching off, are safe and reliable in use, and remarkably prolong the service life.
