Brief introduction of structure
Circuit breaker has the advantages of compact structure, small size and other characteristics. Circuit breaker main body is composed of an insulating casing, the contact breaker, operating mechanism, electric energy storage mechanism and other components. Fixed breaker is composed of a main body and mounting plate; drawer type circuit breaker is composed of a main body and the drawer seat, the drawer seat rails can drive circuit breaker body to pull into pull, it has three working positions: " connected ", " test ", " separation ", position changes through the handle moved to achieve. The three position is directed through the drawer bottom base white pointer display.
When in the " connected " position, the main circuit and the two circuit are connected; when in the " test " position, only the two loop is switched on, the main loop is disconnected, this location can be some necessary test; when in the " separation " position, the main loop and two loop disconnects. |
