Abstract

A high-voltage switchgear with an electromagnetic lock, including a high-voltage switch, a first electromagnetic locking mechanism, and a second electromagnetic locking mechanism, the high-voltage switch includes a control module and a switch execution module; the control module is used to execute the switch The switch execution module is used to perform the actual switching operation of the high-voltage circuit; the switch execution module includes: a support frame (12), a moving contact (1), an impacted contact (2), a first telescopic The limit pin (6), the second telescopic limit pin (7) and the third telescopic limit pin (8), the moving contact (1) and the impacted contact (2) are respectively connected to two high-voltage circuit terminal, the support frame (12) supports the moving contact (1) and the impacted contact (2); the first telescopic limit pin (6), the second telescopic limit pin (7) and the first telescopic limit pin (7) Three telescopic limit pins (8) are sequentially arranged in the support frame (12) from right to left.

Description

technical field [0001] The present application relates to the field of high-voltage switches, in particular to a high-voltage switchgear with an electromagnetic lock. Background technique [0002] A high-voltage switch is a common switch in the field, and its high-voltage-resistant material and layout design have mature solutions in the field. In order to realize the remote operation of the high voltage switch, there is now a high voltage disconnector. [0003] Since sparks, arcs and other phenomena are prone to occur in high-voltage lines, the opening and closing actions of high-voltage switches often require faster speeds. However, when the speed is high, it is prone to large shock and vibration, which affects the reliability and safety of electrical equipment. SUMMARY OF THE INVENTION [0004] The invention provides a control method of a high-voltage isolation switch, which can realize the action of a remote high-voltage switch, and at the same time, its impact is sma...
