Abstract

A circuit breaker according to the present disclosure includes a cradle having an accommodation space therein, the cradle having a plurality of terminals and a breaker main body having a plurality of terminal connectors contactable with the terminals, respectively, and a plurality of vacuum interrupters connected to the terminal connectors, respectively, the breaker main body being installed within the cradle to be movable between a connected position where the terminal connectors are connected to the terminals and a disconnected position where the terminal connectors are separated from the terminals. Each of the terminal connectors includes a plurality of segment conductors each having one end connected to the vacuum interrupter and the other end facing the terminal. According to the configuration, an amount of heat radiated may increase without an increase in an amount of copper used, thereby facilitating for cooling the terminal connectors.

Description

technical field [0001] This specification relates to a circuit breaker, and more particularly, to a circuit breaker capable of increasing the amount of heat radiation without increasing the amount of copper used. Background technique [0002] Generally speaking, a circuit breaker is a device for opening and closing the normal load of a circuit and blocking fault current. For example, a vacuum interrupter can open and close an electrical circuit and quickly interrupt the electrical circuit by extinguishing an arc within the vacuum interrupter that is generated while interrupting a fault current. The vacuum circuit breaker may be installed together with a distribution board (switchboard) in which various electrical equipment including circuit breakers are placed and managed for operation or control of power generation stations and substations, operation of electric motors, and the like. [0003] figure 1 is a perspective view showing the interior of a circuit breaker accordi...
