Description

A self-locking clamp for live work on distribution lines

technical field

The utility model relates to the technical field of electric power maintenance equipment, in particular to a self-locking clamp for live work of distribution lines.

Background technique

At present, the live work of the distribution network around the world, Japan has achieved 100% of the insulation rod operation of the live work project of the distribution network, and France has achieved 90% of the insulation rod work of the live work project of the distribution network. The live work of the domestic distribution network is mainly based on the insulation glove operation method in the insulated bucket arm vehicle, supplemented by the insulation rod operation method. Among them, the insulation rod operation method uses the tie wire for the lapped drain line, the wire is difficult to tie tightly, and the winding is difficult Higher, the use of parallel groove wire clips, puncture wire clips, C-type wire clips, and J-type wire clips in the operation requires extremely high skill level of operators, which is extremely difficult, time-consuming and labor-intensive, and increases the risk of electric shock for operators. .

As an easy-to-operate insulated operating handle introduced from the United States in recent years, the gun-type operating lever is mainly used for the operation of American electrical equipment. The gun-type operating lever can clamp most of the American electrical equipment operation accessories, and install the American grounding clamp and jumper clamp. Use the switch on the handle to push the built-in gripping nozzle, and then retract the gripping nozzle to fix the accessory firmly on the top of the operating rod. When releasing, just push it out. It is easy to open and close, and the operation and positioning are firm and easy to operate. easy. The insulation drain wire of the existing distribution network live work cannot be installed with an insulation operating rod. The development of a self-locking special fixture that uses a gun-type operating rod to install insulation drainage lines will solve the problem of using insulation rods to install existing insulation drainage lines, while reducing the work intensity of operators and improving the safety of operations.
