Indoor high-voltage grounding switch capable of warning in place

Abstract

The invention discloses an indoor high-voltage grounding switch capable of warning in place. The indoor high-voltage grounding switch comprises a base, static contacts, movable contacts, insulators, rotation shafts and half-I-shaped sliding rail supports, wherein the rotation shafts are connected to the base, the half-I-shaped sliding rail supports are fixedly sleeved on the rotation shafts, a lower gear sliding rail is formed in each boss part and faces a direction of each insulator, the bottom of each movable contact is connected with the half-I-shaped sliding rail support by an upper gear sliding block and moves upwards and downwards, a gear sliding strip structure is arranged at a position, corresponding to the upper gear sliding block, in the half-I-shaped sliding rail support, a front end of the upper gear sliding block is connected with a lower sliding block through a pull rod and moves forwards and backwards in the lower gear sliding rail, a point contact type in-place switch is also arranged at a position of a top part of the movable contact, a top part of the point contact type in-place switch is connected with an indication lamp, and the indication lamp is connected with a position of a top part of the static contact. The indoor high-voltage grounding switch stably moves upwards and downwards within a travelling range, and has relatively good stability and reliability.

Description

technical field [0001] The invention relates to the technical field of an indoor high-voltage grounding switch, in particular to an indoor high-voltage grounding switch for warning in place. 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 O...

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
