A switchgear moving end assembly and switchgear

Abstract

The invention belongs to the field of switch devices, and in particular relates to a switch device movable end assembly and a switch device. The cushioning device is only compressed at the end of the travel of the lower conductive tube to provide resistance to relative movement between the tie rod and the lower conductive tube. The setting of the elastic buffer device increases the movement difficulty of the lower conductive tube at the end of the movement stroke of the lower conductive tube, reduces the impulse of the moving end component, and avoids overshooting or over-closing caused by overshooting during opening or closing. In addition, due to the elasticity The buffer device is only compressed at the end of the movement stroke of the lower conductive tube. Therefore, the setting of the elastic buffer device will not affect the movement process of the lower conductive tube between the closing position and the opening position, so as to ensure the normal operation of the moving end assembly. Switch between closed state and open state.

Description

technical field [0001] The invention belongs to the field of switch devices, and in particular relates to a switch device moving end assembly and a switch device. Background technique [0002] The isolation / earth switch includes a static contact, a moving end assembly and a moving contact arranged on the top of the moving end assembly, wherein the moving end assembly further includes a base and two folded conductive arms mounted on the base, and the conductive arms pass through the lower part. The conductive tube and the pull rod located in the lower conductive tube are hinged on the base, and the hinge points of the lower conductive tube and the pull rod on the base are different. The lower conductive tube is connected with the driving device in a transmission, and can perform a pitching motion around the hinge point between a vertical position and a horizontal position under the driving of the driving device, so as to realize the pitching motion of the conductive arm.
