Title:
PERMANENT-MAGNET VACUUM CIRCUIT BREAKER WITH HIGH STABILITY
Document Type and Number:
WIPO Patent Application WO/2022/094856
Kind Code:
A1
Abstract:
A permanent-magnet vacuum circuit breaker (16) with high stability, the circuit breaker comprising a mounting frame (1), a permanent-magnet vacuum circuit breaker (16) and two housings (22), wherein the permanent-magnet vacuum circuit breaker (16) is arranged at a front surface of the mounting frame (1); a nut (2) is clamped on a back surface of the mounting frame (1); the nut (2) is in internally threaded connection with a threaded rod (3); one end of a front surface of the threaded rod (3) is fixedly connected to a back surface of a rotating mechanism (4); and the rotating mechanism (4) is clamped on a back surface of a push plate (5). With regard to the permanent-magnet vacuum circuit breaker (16) with high stability, the permanent-magnet vacuum circuit breaker (16) is moved by arranging the nut (2), the threaded rod (3), clamping mechanisms (11), a roller (12) and clamping grooves (14). When the permanent-magnet vacuum circuit breaker (16) drives the clamping mechanisms (11) to move to a suitable position, the threaded rod (3) is rotated forwards, such that the roller (12) drives the clamping mechanisms (11) to move upwards and be engaged in the clamping grooves (14), and eight clamping mechanisms (11) and eight clamping grooves (14) mutually cooperate to fix the permanent-magnet vacuum circuit breaker (16), thereby increasing fixing nodes of the permanent-magnet vacuum circuit breaker (16) and improving the fixing stability of the permanent-magnet vacuum circuit breaker (16).
