Problems solved by technology

However, some existing circuit breakers, such as vacuum circuit breakers, can only realize single-action for breaking or closing the circuit during use, which leads to high-voltage arc generation when it breaks or closes the high-voltage circuit. The time is longer, and it is easy to burn the circuit breaker; so now there is an urgent need for a switching device that can quickly break or close the high-voltage circuit

Abstract

The invention discloses a double-acting switch device which comprises a mounting base, a switch assembly and a linkage mechanism are mounted in the mounting base, the switch assembly comprises a housing, an upper feeler lever component and a lower feeler lever component, the housing is in sliding fit with the mounting base, and the upper feeler lever component and the lower feeler lever component are mounted on the upper portion and the lower portion of the housing respectively. The lower feeler lever component is connected with the housing in a matching manner; the linkage mechanism is respectively connected with the upper feeler lever component and the housing, the linkage mechanism is suitable for driving the upper feeler lever component and the housing to synchronously move towards or away from each other, and the lower feeler lever component is suitable for synchronously moving along with the housing; therefore, the upper feeler lever component and the lower feeler lever component are in contact with each other or separated from each other to switch on or off a high-voltage circuit. The switch assembly has the beneficial effects that the upper contact rod part and the lower contact rod part synchronously move towards each other or back to each other, so that double-acting operation on the on-off or on-off of a high-voltage circuit can be realized, and the on-off or on-off time of the switch assembly is effectively shortened.

Description

technical field [0001] The present application relates to the field of high-voltage equipment, in particular to a high-voltage switchgear. Background technique [0002] High-voltage switches are mainly used for breaking and closing high-voltage circuits above 3kV. Commonly used high-voltage switches include vacuum circuit breakers, oil circuit breakers and sulfur hexafluoride (SF 6 ) circuit breakers, etc. [0003] Since the high-voltage switch is used in a high-voltage circuit, no matter what kind of circuit breaker, it needs to act quickly when breaking and closing the circuit. However, some existing circuit breakers, such as vacuum circuit breakers, can only realize single-action for breaking or closing the circuit during use, which leads to high-voltage arc generation when it breaks or closes the high-voltage circuit. The time is longer, and it is easy to burn the circuit breaker; so there is an urgent need for a switching device that can quickly break or close the hig...
