Translational motion type indoor high-voltage earthing switch

Abstract

The invention discloses a translational motion type indoor high-voltage earthing switch comprising an L type pedestal, a static contact, a moving contact, an insulator and a vertical sliding unit. The static contact is fixed at the top of the insulator by the L type bracket; and the insulator is fixed at the top of the rear side of the pedestal. The static contact, the moving contact, and the vertical sliding unit coat the inside of an L-shaped bending head of the L type bracket; and the moving contact is clamped at the top of the vertical sliding unit. A support sliding table is provided with a horizontal chute facing the bottom of the moving contact; a bidirectional motor and a push rod are connected to the horizontal chute; a top block is connected to the other end of the push rod; and the bottom of a contact rod is connected to an inclined chute and the contact rod slides up and down with the top block. A point contact type in-place switch is arranged at the top of the moving contact; and an indication lamp is connected to the top of the point contact type in-place switch and is connected to the top of the static contact. According to the translational motion type indoor high-voltage earthing switch, the switch can move up and down stably in a stroke range; and the stability and reliability of the switch are high.

Description

technical field [0001] The invention relates to an indoor high-voltage grounding switch in the technical field, in particular to a translational indoor high-voltage grounding switch. Background technique [0002] The existing manual grounding switch of the switch cabinet is generally not compatible with manual operation and electric operation at the same time. The manual operation uses the travel switch to sense whether the switch is in place. The closing and opening action of the operation is slow, unstable and reliable, and will interfere with each other. A special switching mechanism is required to have manual operation and electric operation at the same time. [0003] Chinese patent CN 103500671 B discloses an indoor high-voltage electric grounding switch, including a static contact, a moving contact, a main shaft, an electric mechanism and a base, the static contact is fixed on the base through an insulator, and the moving contact is fixed through a crank arm On the ma...

Problems solved by technology

[0004] However, when this kind of manual and electric integrated switch is closed, the purpose of closing or opening cannot be achieved due to insufficient power or bidirectional motor failure. At the same time, the closing and opening structures are relatively complicated, and it is inconvenient to maintain and use later.

And when the switch is in use, because the switch is not in place, it cannot directly go to the working state, and it needs to be manually operated again, which affects the work efficiency

And the phenomenon that the gate is not in place will also appear
