Abstract

The invention relates to an elastic operation switch system which is characterized in that the system comprises a base plate, a high-voltage switch and an operating mechanism. The operating mechanismis arranged on the base plate. An output end of operating mechanism is connected to the high-voltage switch. According to the system, through the cooperation of an elastic operation cam structure anda dual-rocker mechanism, the accurate swing of the high-voltage switch is achieved. A cam mechanism is powered by an independent stepper motor, and the overall stability performance is improved. The elastic operation cam structure is used in the invention, compared with a general high-voltage switch operation structure, force closure and a more stable structure can be achieved by the structure.

Description

technical field [0001] The invention relates to the field of electric devices, in particular to an elastic switch system. Background technique [0002] There is a high-voltage vacuum switch on the market, which includes a housing and three horizontal vacuum interrupters located in the housing, and uses a spring-operated drive mechanism to realize the opening and closing action. Its disadvantages are: the ordinary The driving mechanism of the high-voltage switch has many components, which are prone to failure. Because the driving mechanism of the general high-voltage switch is relatively large, it needs to be installed on the outer wall of the housing, resulting in a large overall space occupation, which not only increases the cost, but also poses a burden on transportation and transportation. Installation brings various inconveniences. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a spring-operated switch syst...
