Outdoor high-voltage vacuum intelligent circuit breaker

Abstract

The invention discloses an outdoor high-voltage vacuum intelligent circuit breaker which comprises a mechanism box and a special-shaped shaft, one side of the mechanism box is rotationally connected with an isolation main shaft; and an operation handle is fixedly connected to the front end of the isolation main shaft, a fixed sliding plate is fixedly connected to the lower portion, close to the operation handle, of the mechanism box, sliding pull rods are slidably connected to the two sides of the fixed sliding plate, special-shaped sleeves are fixedly connected to the lower surfaces of the sliding pull rods, and anti-theft shafts are in threaded connection with the lower ends of the sliding pull rods. The invention discloses the outdoor high-voltage vacuum intelligent circuit breaker, special-shaped shafts, the sliding pull rods, the special-shaped sleeves and the shell are arranged in a matching manner, the outdoor high-voltage vacuum intelligent circuit breaker has the effect of preventing non-professionals from rotating the operation handle, and the outdoor high-voltage vacuum intelligent circuit breaker has the effect of facilitating observation of the indication state of theopening and closing indication board through the cooperative arrangement of an opening and closing indication pointer, a sliding groove plate, a light reflecting plate and a baffle.

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 secondary system of circuit breaker built 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, detect equipment defects and faults, and send out alarm signals before defects become faults, so as to take measures to avoid accidents. The intelligent circuit breaker realizes electronic operation, changes the mechanical energy storage to capacitor energy storage, and changes the mechanical transmission to the direct drive of the inv...
