Embodiment Construction

[0026] figure 1 , image 3 The interlocking device for high-voltage switchgear disclosed by the present invention includes an isolating switch operating mechanism, a circuit breaker opening and closing mechanism, and a transmission mechanism arranged between the isolating switch operating mechanism and the circuit breaker opening and closing mechanism.

[0027]The isolating switch operating mechanism includes: an operating handle 18 arranged on the outer end of the locking operation panel for controlling the opening and closing of the isolating switch, and a shift fork arranged on the inner side of the locking operating panel, the operating handle 18 and the dial The fork is fixedly connected through a rotating shaft passing through the locking operation panel. When the handle 18 turns, it drives the shift fork to rotate together.

[0028] The opening and closing mechanism of the circuit breaker includes a closing shaft 10 and a closing bent plate 11 for controlling the clos...

Abstract

The invention discloses an interlocking device used for high-voltage switch equipment. The interlocking device comprises an isolation switch operation mechanism and a circuit breaker on-off mechanism and also comprises a transmission mechanism, wherein one end of the transmission mechanism is connected with a shifting fork of the isolation switch operation mechanism, the other end of the transmission mechanism is arranged at the bottom of a circuit breaker and is connected with the circuit breaker on-off mechanism, and the transmission mechanism comprises a link mechanism arranged at the outer side of the circuit breaker and a lever mechanism arranged at the inner side of a circuit breaker. The interlocking device used for the high-voltage switch equipment is arranged at the bottom of the circuit breaker, and therefore, compared with the existing interlocking device, the interlocking device used for the high-voltage switch equipment is simple in structure, flexible in transmission, safety in use, reliable in interlocking and convenient in manufacturing, installation and debugging.

Description

technical field [0001] The invention belongs to the technical field of high-voltage power distribution equipment, and in particular relates to an interlock device of a fixed high-voltage switch cabinet. Background technique [0002] The interlocking device between the existing fixed high-voltage switchgear circuit breaker (mechanism and switch integrated type) and the disconnector is mainly to meet the requirement that the user cannot operate the disconnector operating mechanism to disconnect the disconnector or disconnect the circuit breaker when the circuit breaker is closed. When the circuit breaker is open, the user can operate the isolating switch operating mechanism to manually close the circuit breaker when it is in the "inspection position", and maintain the open state when it is in the "break and lock position". [0003] Most of the existing interlocking devices for high-voltage switch cabinets adopt two methods. One is to connect the shift fork on the locking opera...
