Drop insurance upper pile head lead wire splint type insulation fixing bracket

Abstract

The invention discloses a clamping plate type insulated fixing support for the leading wire and the conducting wire of the pile head of a drop-out fuse, which comprises a support clamping plate, a vertical guide rod and lock bolts, wherein a longitudinal circular hole is arranged on the support clamping plate, and the vertical guide rod is arranged in the longitudinal circular hole; the lock boltof the vertical guide rod is arranged on the support clamping plate along the radial direction of the longitudinal circular hole, and a swing joint with a transverse circular hole is hinged on the upper end of the vertical guide rod; an insulated hollow horizontal guide rod is arranged in a transverse circular hole, and the lock bolt of the horizontal guide rod is arranged on the swing joint; anda conducting wire clamping plate is arranged at the front end of the horizontal guide rod, and the front end of the conducting wire clamping plate is of a hook shape, and is capable of hooking and locking the leading wire. The clamping plate type insulated fixing support is an insulated clamping tool with a working range of a spherical space of which the radius is 600mm, can effectively fix the free end of the upper leading wire, tow the leading wire away from a working point, and perfectly ensure safe working space needed by replacing a drop-out fuse support.

Description

Technical field: [0001] The invention relates to an insulating fixing jig for live work, in particular to an insulating fixing bracket used for moving and fixing the lead wire of a pile head when replacing a drop insurance with live electricity. Background technique: [0002] The drop insurance is a safety device for preventing short circuit of the distribution transformer on the incoming line channel. The head material is made of copper material. [0003] The entry and exit pile head of the drop insurance is used to connect the outgoing line of the 10kV line and the incoming line of the transformer, which itself is connected in series in the line. The connection wires at both ends of the drop insurance are made of aluminum, so that the drop insurance connected in series on the line has two copper-aluminum joints. The drop insurance is installed bare and exists in the atmosphere containing water vapor, oxygen and dust impurities. The copper-aluminum joint forms a chemical ...

Problems solved by technology

During this process, the workers are close to the high-voltage electrified body, and their bodies move and move a lot. The protection range of insulating tools and appliances is small, and there is a great risk of electric shock, high labor intensity, and difficulty in high-altitude operations with large displacements.
