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

Abstract

The invention discloses a swinging type indoor high-voltage grounding switch. The swinging type indoor high-voltage grounding switch comprises an L-shaped base, a static contact, a movable contact, an insulator, a rotary shaft and a vertical sliding apparatus; the rotary shaft is connected with two supporting lugs of the base for rotation; the static contact, the movable contact and the vertical sliding apparatus are all coated in an L-bending head of an L-shaped bracket; a clamping groove is formed in the top of a direct clamping sleeve; the static contact is directly aligned to the interior of the clamping groove; a vertical clamping sleeve is fixed on the top of a vertical rocking arm, and the bottom of the vertical rocking arm is fixedly connected with a vertical cam; a point contact type location switch is also arranged on the top of the movable contact; the top of the point contact type location switch is connected with an indicator lamp, and the indicator lamp is connected with the top position of the static contact; and the bottom of the point contact type location switch triggers a switch thereof through an ejection rod, wherein the ejection rod is fixed on the top of the movable contact. The swinging type indoor high-voltage grounding switch can move up and down stably within the travel range, so that the swinging type indoor high-voltage grounding switch has relatively high stability and reliability.

Description

technical field [0001] The invention relates to the technical field of an indoor high-voltage grounding switch, in particular to a swing-type 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 main ...
