Abstract

The invention discloses a transmission line tower grounding resistance measuring device, and relates to the field of transmission line monitoring. The device comprises a box body, a box cover, two bulges, an opening, a drawing plate, a locking piece, a measuring line receiving and transmitting mechanism, a tower grounding resistance measuring instrument and a measuring line, wherein the box coveris arranged on the box body through a hinge; the two bulges are arranged along the inner side wall of the box body; a slideway is formed between the two bulges; the opening is formed in the front surface of the box body; the drawing plate is inserted into the box body through the opening in the front surface of the box body; the edge of the drawing plate slides into the slideway along the two bulges and is clamped and fixed by the bulges; the interior of the box body is divided into an upper layer space and a lower layer space through the drawing plate; one part of the locking piece is fixed on the drawing plate, and the other part of the locking piece is fixed on the front surface of the box body; the drawing plate is locked in the box body through the locking piece; the measuring line receiving and transmitting mechanism is arranged in the upper layer space of the box body; and the tower grounding resistance measuring instrument and the measuring line are arranged in the lower side space of the box body. According to the device, unified management and storage of tools can be realized, the tools are prevented from being lost and omitted, the working efficiency is improved, the receiving and transmitting are convenient, the operation is simple, and the labor intensity of measuring personnel is reduced.

Description

technical field [0001] The invention relates to the technical field of transmission line monitoring, in particular to a grounding resistance measuring device for transmission line poles and towers. Background technique [0002] Power transmission is achieved by using a transformer to boost the power generated by the generator, and then connecting it to the transmission line through circuit breakers and other control equipment. According to the structural form, transmission lines are divided into overhead transmission lines and cable lines. The overhead transmission line is composed of line towers, wires, insulators, line fittings, guy wires, tower foundations, grounding devices, etc., and is erected above the ground. Among them, the grounding device is used to guide and discharge the lightning current into the ground, so as to maintain the lightning resistance performance of the line. The resistance value of the grounding resistance of the tower can directly reflect whethe...
