Ground potential operation non-bearing connection wire clamp

Abstract

The invention provides a ground potential operation non-bearing connection wire clamp. The ground potential operation non-bearing connection wire clamp comprises a wire clamp body, a drainage wire pressing plate, bolted connection assemblies, a bus fastener, a driving screw, a guide sleeve, a sliding sleeve and a shaft pin. The drainage wire pressing plate is in bolted connection with the wire clamp body through the bolted connection assemblies, the bus fastener is in threaded connection with the driving screw, and the sliding sleeve is fixedly installed on a connecting lug plate through a connecting through hole of the connecting lug plate of the wire clamp body in a vertical interference fit mode. The inner wall of the guide sleeve and the upper end of a thread driving column of the driving screw are in threaded connection and then connected in a pin joint mode through the shaft pin. The outer wall of the guide sleeve and the inner wall of the sliding sleeve can be connected in a sleeved and vertical sliding mode. The ground potential operation non-bearing connection wire clamp is simple in structure, low in cost, convenient to mount and demount, and high in working efficiency and applicability, time and labor are saved, construction can be directly conducted under the power-outage-free condition, and unnecessary economic and social losses caused by power outage construction can be effectively avoided.

Description

technical field [0001] The invention relates to a power-taking device in an overhead power distribution line, in particular to a non-load-bearing splicing clip that can be installed and disassembled by electrified ground potential operations. Background technique [0002] The non-load-bearing connection clamp for ground potential operation is a live lapping device for overhead distribution line branches, knife switches, switches and other drainage lines. At present, the non-load-bearing splicing clamps such as parallel trench clamps, amp clamps, C-type clamps, and insulation piercing clamps commonly used on distribution lines did not consider the needs of live work when they were developed. Both require power outage construction, and the frequent power outage construction of distribution lines cannot meet the user's increasingly high requirements for power quality and power supply reliability, and bring unnecessary losses to economic and social development. If the above-men...

Problems solved by technology

At present, the non-load-bearing splicing clamps such as parallel trench clamps, amp clamps, C-type clamps, and insulation piercing clamps commonly used on distribution lines did not consider the needs of live work when they were developed. Both require power outage construction, and the frequent power outage construction of distribution lines cannot meet the user's increasingly high requirements for power quality and power supply reliability, and bring unnecessary losses to economic and social development.

If the above-mentioned clamps need to be operated with ground potential insulating operating rods, it is necessary to temporarily develop targeted special tools, and these temporarily developed special tools have limitations, long working hours, and difficult operations, so it is difficult to be popularized

At present, with the improvement of insulation protection technology, the direct operation method of insulating bucket arm truck and insulating gloves is used to carry out related operations, but this operation method has relatively high requirements for the working environment such as roads and ground, such as places that cannot be reached by insulating bucket arm vehicles. It is not possible to complete the construction in this way
