A kind of insulation rod with double clamps and mother and child for live work

Abstract

The invention discloses a double chuck insulation rod for live work, comprising an insulation rod and a sleeve rod, both rods are cylindrical, the outer surface of the insulation rod is sleeved with a sleeve rod, and the upper end of the insulation rod is plugged with a positioning rod. The collet and the sleeve rod are inserted into the sleeve rod hole of the splint, and the inner surface of the splint is fixedly connected with a wire-taking chuck by bolts. In use, the female clamp is clamped on the main line, which plays a pre-positioning role. The sub-clamp is clamped to the equipment lead. After the equipment lead is removed, the lead is separated from the main line through the sleeve rod, which can reliably control the fall and swing of the lead and extend the insulation distance. Safe, after on-site application, the lever is easy to operate, safe and reliable, saves time and effort in on-site use, and can be operated by one person with one hand. Labor intensity, reduced working time, easy to use, easy to promote and apply, in line with the development direction of non-stop operation.

Description

technical field [0001] The invention relates to the technical field of circuit maintenance, in particular to a double-clamp sub-female insulation rod for live work. Background technique [0002] In the field of 10kV power distribution, it is often necessary to overhaul the power supply line. The ordinary maintenance method requires power outage planning operation. Nowadays, the technology of non-stop operation of distribution network is widely used. Directly reach the live parts, and then directly contact the live equipment or lines for maintenance. Among them, the work of replacing the switch on the distribution network column with load without power failure is a relatively complicated third type of live work project, which is currently promoted by the China Electricity Council and the State Grid Corporation. The operation method is based on the insulated glove operation method of bypass cables and insulated drain wires. The work process is not only time-consuming and labor...

Problems solved by technology

[0002] In the field of 10kV power distribution, it is often necessary to overhaul the power supply line. The ordinary maintenance method requires power outage planning operation. Nowadays, the technology of non-stop operation of distribution network is widely used. Directly reach the live parts, and then directly contact the live equipment or lines for maintenance. Among them, the work of replacing the switch on the distribution network column with load without power failure is a relatively complicated third type of live work project, which is currently promoted by the China Electricity Council and the State Grid Corporation. The operation method is based on the insulated glove operation method of bypass cables and insulated drain wires. The work process is not only time-consuming and labor-intensive, but also has risk factors. Therefore, how to repair the circuit without cutting off the electricity consumption of residents has always been the concern of professionals. The key issue, to achieve this, first of all, it is necessary to effectively cut off the direct contact between the operator and the live equipment and lines, and secondly, it is necessary to pre-position the maintenance line so that the wires can be accurately returned to their original positions after the maintenance

[0003] The existing maintenance tools for changing the switch on the distribution network post without power failure and load are not ideal enough. There are disadvantages such as unsmooth use, inability to pre-position, and failure to effectively ensure safety. Moreover, a clamping structure is easy to cause the lead wire to fall off, which seriously affects the On-site operation safety, extended operation time
