Auxiliary tool general for one-time nuclear phase of switch cabinet

Abstract

The invention discloses an auxiliary tool general for a one-time nuclear phase of a switch cabinet. The tool comprises rollers, two insulation blocks, a connecting rod and a push-pull structure. The two insulation blocks are arranged in parallel and perpendicularly connected with the two ends of the connecting rod respectively, a rotating shaft is arranged at the lower portion of each insulation block, the rollers are connected with the insulation blocks through the rotating shafts, the axis of the rotating shafts is parallel to the axis of a connecting rod assembly, a gear pulley positioningblock is connected to the outer side of the upper portion of each insulation block, a gear pulley is matched with the gear pulley positioning block, the axial positions of the insulation blocks on theconnecting rod are adjustable, the push-pull structure is connected with the connecting rod at the middle of the axial direction of the connecting rod. Due to the fact that the axial positions of theinsulation blocks on a screw are adjustable, it is ensured that the position of the gear pulley positioning block is adjustable, the width between opening top plates on the two sides of the tool is continuously adjustable, the tool can adapt to switch cabinets of different types, the safe and efficient one-time nuclear phase is achieved, and the tool is convenient to assemble, disassemble, use and store, and convenient to carry and transport.

Description

technical field [0001] The invention relates to the technical field of substation detection equipment, in particular to a universal auxiliary tool for primary nuclear phase of a switch cabinet. Background technique [0002] In the substations belonging to the power supply company, except for a few substations that are old-fashioned open 10kV switches, the 10kV side switches of other substations are fully enclosed switchgear models. When performing a phase check on a fully enclosed live-running switchgear, the isolation baffle is in a closed state, and it is necessary to try to open the high-voltage isolation baffle to expose the upper and lower 10kV live contacts behind the baffle, and put the phase-nucleation instrument into it to obtain Power supply information at both ends, check whether the ABC phase sequence at both ends is consistent, this is an item that must be checked before the "hand in hand" distribution line switch is powered on. The present invention is to inve...

Problems solved by technology

When using the "pick open method", the staff must lean into the switch cabinet. It is difficult to maintain a safe distance of at least 0.35 meters from the 10kV live equipment, and the tools used such as insulating rods are very easy to accidentally touch the live static contact. big security risk
