Problems solved by technology

[0002] Traditionally, the T-junction clips used by medium-voltage power consumers for temporary power connection must be installed by construction personnel in contact with overhead wires (power outage or equipotential live work), which not only affects the normal operation of the line, but also has poor safety

Embodiment Construction

[0008] As shown in the figure, the medium-voltage live line lead clamp includes a hook-shaped conductive seat 1, and a terminal 2 for connecting external leads 5 is arranged on the outside of the conductive seat. The elastic conductive clip 3 of the bare wire, the lower end of the conductive seat is provided with a section of screw rod 4 for connecting with the insulating operating rod. The elastic conductive clip 3 includes a pair of contact pieces 6 arranged in a "character-eight" shape. The lower ends of the two contact pieces are connected to the lower part of the conductive seat, and the upper ends of the two contact pieces are respectively placed in two empty grooves 7 on the upper part of the conductive seat. A leaf spring 8 is installed between the outside of the sheet and the conductive seat, and the elastic force of the leaf spring makes the two contact sheets approach each other. The upper ends of the two contact pieces are also conductively connected to the base of...

Abstract

The invention belongs to a live line work tool of a medium voltage transmission line, in particular to a lead clamp for a medium voltage live circuit which is used for leading out wiring from an overhead conductor when electricity is temporarily used. The lead lamp comprises a hook-shaped conductive seat, wherein the outside of the conductive seat is provided with a connecting terminal for connecting an external lead wire; the inside of the hook part of the conductive seat is provided with an elastic conductive clamp for clamping an overhead bare conductor; the lower end of the conductive seat is provided with a section of screw for connecting an insulating operating lever; the elastic conductive clamp comprises a pair of wafers arranged in a splayed shape; the lower ends of the two wafers are connected with the lower part of the conductive seat, while the upper ends are arranged in two empty slots of the upper part of the conductive seat respectively; spring strips are arranged between the outside of the two wafers and the conductive seat; and the elasticity of the spring strips makes the two wafers be close to each other. The lead clamp effectively solves the problems that electricity is hard to cut off or a live line work vehicle cannot be in place in lapping operation, is convenient for earth potential live line work lapping on the overhead bare conductor, and has high safety.

Description

technical field [0001] The invention belongs to live working tools for medium-voltage power transmission lines, in particular to a medium-voltage live line lead clamp used to lead out wiring from overhead wires during temporary power use. Background technique [0002] Traditionally, the T-junction clamps used by medium-voltage power consumers for temporary power connection must be installed by construction workers in contact with overhead wires (power outage or equipotential live work), which not only affects the normal operation of the line, but also has poor safety. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a medium-voltage live line lead-wire clamp capable of lapping the medium-voltage live line with simple operation and good safety. [0004] The medium-voltage live line lead clip of the present invention includes a hook-shaped conductive seat, and a connecting terminal for connecting external leads is a...
