Abstract

This invention relates to a vacuum breaker of a solid-sealed outdoor high voltage phase controlled synchronous permanent magnet unit, in which, three insulation shells in the same internal structure are fixed on the upper end of the base, a permanent magnet is fixed at the bottom of the insulation shell, one end of the power output shaft of the magnet unit is connected with a high strength insulation pull rod, the other end of the rod is hinged on the moving touch rod of a vacuum quenching chamber fixed on a low line end by soft connection, the quenching chamber is fixed on the top of the shell, the static contactor of the quenching chamber is fixedly-connected with the upper inlet wire end cover electrically, a fixed frame is set at the bottom of the base, a control box is fixed on the frame with PLC, CPU single-chip processor, current and voltage phase detector and a controller electrically connected with the coil of the magnet unit.

Description

(1) Technical field [0001] The invention relates to a solid-sealed outdoor high-voltage phase-controlled synchronous permanent magnet mechanism vacuum circuit breaker, which is suitable for industrial and mining enterprises, power plants and substations to control and protect rated frequency 50Hz, rated voltage 12kV, 40.5kV, 126kV voltage level three It is used for interphase AC capacitive loads and inductive loads, especially for switching capacitor banks, transformers, reactors and other occasions that require frequent operations. (two), background technology [0002] At present, domestic outdoor vacuum circuit breakers with a voltage level of 12kV and above mostly use spring energy storage operating mechanisms, which are attached to the outside of the circuit breaker body. Due to its complex mechanism, many intermediate transmission links, and the inability to be sealed as a whole, the operating mechanism with adhering dirt or serious corrosion is prone to misoperation or...
