Abstract
The utility model has the technical scheme that a vacuum circuit breaker self-adaptive operating mechanism with the properties of permanent magnet and spring mechanisms is mainly formed by connecting a spring operating device, a flexible connector and a permanent magnet device through a drive rod and a main shaft which are joinable. A cam in the spring operating device is connected with one end of the flexible connector by a connecting-rod end of a cam drive rod through a rotation shaft, 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 a spring energy storage part is connected with the flexible connector for driving the main shaft to carry out the closing operation. The flexible connector absorbs interference energy of the spring part. The connection with the permanent magnet device is completed. Under normal conditions, the permanent magnet device completes the normal closing and opening processes through the permanent magnet controller.
