Abstract

The invention has the technical scheme that a vacuum circuit breaker self-adaption operating mechanism with the properties of a permanent magnet and a spring mechanism is mainly formed by connecting a spring operating device, a flexible connector and a permanent magnet device through a joinable drive rod and a joinable main shaft, wherein a cam in the spring operating device is connected with one end of the flexible connector through a connecting-rod end of a cam drive rod, and the other end of the flexible connector is connected with the permanent magnet device through the main shaft. When no power supply is externally provided or a permanent magnet controller fails to work, energy is stored in the spring mechanism manually, and the energy storage part of a spring is connected with the flexible connector for driving the main shaft to carry out the closing operation. The flexible connector absorbs the interference energy of the spring part. Consequently, the connection with the permanent magnet device is completed. Under normal condition, the permanent magnet device completes the normal closing and opening processes through the permanent magnet controller.

Description

technical field [0001] The invention belongs to an operating mechanism used in a power system circuit breaker, and is an adaptive operating mechanism with characteristics of permanent magnet and spring mechanism. Background technique [0002] At present, the operating mechanisms of vacuum circuit breakers mainly include electromagnetic operating mechanisms, spring operating mechanisms and permanent magnetic operating mechanisms. [0003] The electromagnetic operating mechanism has been widely used in the early stage of the development of vacuum circuit breakers, but the electromagnetic operating mechanism has a bulky structure and takes a long time to operate. Closing operation is not possible without power supply. [0004] The spring operating mechanism is the most commonly used type of operating mechanism for vacuum circuit breakers. Its advantage is that it does not require a high-power DC power supply, but only needs a low-power AC-DC dual-purpose energy storage motor, ...
