Abstract

A vacuum circuit breaker comprises: a plurality of switching mechanism units having movable contacts and stationary contacts for connecting/breaking an electric circuit between an electric source and an electric load respectively, and disposed in lengthwise direction; an actuator unit including at least one rotary shaft for providing the movable contacts with dynamic power so as to move to positions contacting to the stationary contacts or to positions separating from the stationary contacts; a supporting frame for fixing and supporting the switching mechanism units and the actuator unit; and a transfer link unit for transferring rotating movement of the rotary shaft to a plurality of vertical movements, whereby the vacuum circuit breaker can be easily installed in a power distributing cabinet and a power of the actuator unit can be evenly transmitted to the plurality of switching mechanism units.

Description

Technical field [0001] The present invention relates to a vacuum circuit breaker, that is, an industrial electronic equipment used between power transmission and distribution devices of industrial cables, and more particularly to a vacuum circuit breaker, which can pass through a switch mechanism unit and a switch mechanism unit in the length direction. The actuator unit is installed in a narrow power distribution terminal box. At the same time, the power of the actuator unit can be evenly transmitted to multiple switchgear units. Background technique [0002] Generally, a circuit breaker is an electronic protection device, which can protect electric load devices and power cables from being damaged by large fault currents due to insufficient power and grounding errors in the circuit, and when such fault currents are generated The power-off operation is automatically performed, thereby disconnecting the circuit. [0003] A vacuum circuit breaker is a type of ci...
