Special tool kit for measuring ground resistance of transmission line

Abstract

The invention provides a special tool kit for measuring the ground resistance of a transmission line. The special tool kit comprises a first winding board, a second winding board, and two L-shaped ground bars. A ring detection line is respectively wound around the first winding board and the second winding board. A connection line is arranged between each ring detection line and a corresponding ground bar. Each ring detection line is provided with a plurality of lantern rings. Two ends of the connection line are provided with two chucks. The ring detection lines are connected to the chucks through the lantern rings. With the above structure, the ring detection lines are provided with the lantern rings, the connection with the connection lines is facilitated, the ring detection lines are connected to the chucks through the lantern rings, the lantern rings are aluminum sleeve pipes installed on the outer layers of the ring detection lines, the special tool kit has the advantages that aninternal conductive wire is not damaged after frequent use, a phenomenon that internal metal is broken after the ring detection lines are frequently clamped by the chucks is avoided, the special tookkit is convenient and flexible to use, branch line connection can be adjusted randomly according to different tower types, the service life is long, the measurement data is accurate, and a deviation of a final measured result from an actual value is reduced.

Description

technical field [0001] The invention relates to a tool for measuring the grounding resistance of a power transmission line, in particular to a complete set of tools for measuring the grounding resistance of a power transmission line. Background technique [0002] The grounding resistance of the iron tower must be measured around the earthing resistance value of the iron tower during each periodical measurement or acceptance measurement of the new line. There is no dedicated line, just use a thin wire or ordinary power cord instead, and clamp the wire on the wire for measurement. After these wires are frequently clamped by the chuck, the internal metal strands will be broken, and the final measurement result , may deviate from the actual value. Contents of the invention [0003] In order to solve the above problems, the purpose of the present invention is to overcome the deficiencies of the prior art, and provide a special tool set for measuring the grounding resistance of...
