Problems solved by technology
[0002] The use of high-voltage vacuum permanent magnet circuit breakers is expanding day by day, and it occupies a certain share in the existing market. However, the manual closing function has not been well realized. As a new type of permanent magnet operating mechanism, manual closing has not been realized. Closing is really an important defect in function, and the operation is not convenient enough

Description
technical field [0001] The invention relates to a manual closing mechanism, in particular to a manual closing mechanism of a circuit breaker with a high-voltage vacuum permanent magnet mechanism. Background technique [0002] The use of high-voltage vacuum permanent magnet circuit breakers is expanding day by day, and it occupies a certain share in the existing market. However, the manual closing function has not been well realized. As a new type of permanent magnet operating mechanism, manual closing has not been realized. Closing is really an important defect in function, and the operation is not convenient enough. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a manual closing mechanism of a high-voltage vacuum permanent magnet circuit breaker, which can be closed manually, and is easy to operate, safe and reliable. [0004] According to the technical solution provided by the present...
