Abstract

The invention relates to a hand-operated closing device and an outdoor permanent magnetic circuit breaker. The hand-operated closing device comprises a hand-operated closing support fixedly connectedwith a casing of the outdoor permanent magnetic circuit breaker, a hand-operated closing push rod of which one end is in rotation connection with the hand-operated closing support, a sliding block anda limit pin, wherein the sliding block is in sliding connection with a main shaft of the outdoor permanent magnetic circuit breaker, one side of the sliding block is in sliding connection with the hand-operated closing push rod, the limit pin is fixed on the main shaft in a penetration mode, the hand-operated closing push rod is pushed, and one end of the sliding block is in butt joint with the limit pin to drive the main shaft to move along the length direction to achieve closing. The hand-operated closing device is advantaged in that hand-operated closing operation of the permanent magneticcircuit breaker is realized, closing operation is rapid and can realize force saving, and safety is high.

Description

Technical field [0001] The invention relates to the field of electrical devices, in particular to a manual closing device and an outdoor permanent magnet circuit breaker. Background technique [0002] In recent years, circuit breakers are one of the most widely used and most important core equipment in power transmission and distribution systems, and the safety and reliability of their operations are critical to the power system. With the rapid development of the national economy and electric power industry, the launch of national key engineering projects and the promotion of urbanization, there is an urgent need for large-scale, high-tech, and reliable circuit breakers. Most of the existing permanent magnet mechanism circuit breakers do not have the manual closing function. Especially in the characteristic test, in order to realize the manual closing in the test phase, it is very necessary. The main problem is: the lack of a fast and labor-saving manual Closing device.
