An outdoor high-voltage vacuum intelligent circuit breaker

Abstract

The invention discloses an outdoor high-voltage vacuum intelligent circuit breaker, comprising a mechanism box and a special-shaped shaft. An isolation main shaft is rotatably connected to one side of the mechanism box, an operation handle is fixedly connected to the front end of the isolation main shaft, and the mechanism box is close to A fixed sliding plate is fixedly connected below the operating handle, sliding pull rods are slidably connected to both sides of the fixed sliding block, a special-shaped sleeve is fixedly connected to the lower surface of the sliding pull rod, and an anti-theft shaft is threadedly connected to the lower end of the sliding pull rod. The outdoor high-voltage vacuum intelligent circuit breaker has the effect of preventing non-professionals from turning the operating handle through the cooperation of the special-shaped shaft, the sliding rod, the special-shaped sleeve and the cover. The cooperative arrangement of the chute plate, the reflector and the baffle plate enables the outdoor high-voltage vacuum intelligent circuit breaker to have the effect of facilitating the observation of the state indicated by the opening and closing signs.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to an outdoor high-voltage vacuum intelligent circuit breaker. Background technique [0002] Intelligent circuit breaker is a new circuit breaker secondary system established with microelectronics, computer technology and new sensors. Its main feature is that the execution unit is composed of power electronic technology and digital control device, which replaces the auxiliary switch and auxiliary relay of the conventional mechanical structure. The new sensor cooperates with the digital control device to collect operating data independently, can detect equipment defects and faults, and issue an alarm signal before the defects become faults, so that measures can be taken to avoid accidents. The intelligent circuit breaker realizes electronic operation, changes the mechanical energy storage into capacitor energy storage, and changes the mechanical transmission into the in...
