High-voltage test junction pole

Abstract

The invention discloses a high-voltage test junction pole, which relates to the technical field of electric power circuit high-altitude test tools, and includes an insulated rod and a hook, wherein the insulated rod is a hollow rod; a first connecting sleeve provided with a closed end is arranged at the upper end of the insulated rod; a center hole is formed in the closed end of the first connecting sleeve; the hook includes a lifting hook and a straight rod; threads are arranged at the tail end of the straight rod of the hook; the tail end of the straight rod of the hook penetrates through the insulated rod through the center hole of the first connecting sleeve; a test lead penetrating from the inside of the insulated rod is fixedly connected with the hook through a nut. The test lead in the high-voltage test junction pole penetrates through the inside of the insulted rod, so that electric shock to body or equipment short-circuit accident caused by the fact that the test lead falls down and flies is effectively avoided, and potential safety hazard is reduced.

Description

technical field [0001] The invention relates to the technical field of high-altitude test tools for power lines. Background technique [0002] Power preventive test and routine condition maintenance test are an important link in the operation and maintenance of power equipment, and one of the effective means to ensure the safe operation of the power system. Electric power preventive test refers to the inspection, test or monitoring of the equipment that has been put into operation according to the specified test conditions (such as specified test equipment, environmental conditions, test methods and test voltage, etc.), test items and test cycle. It is an important measure to judge whether the equipment can continue to be put into operation, prevent accidents and equipment damage, and ensure the safe operation of packaging equipment. [0003] In the existing preventive test and routine test of condition maintenance, most of the cases are high-altitude live work, and the con...

AI Technical Summary

Problems solved by technology

The labor intensity of the operators who use the lifting platform is limited by the terrain, and it is difficult to get close to the equipment under test, which wastes time, reduces work efficiency, and poses a great danger to the personal safety of the operators; while the insulating ladder is unstable and easy to break , prone to high-altitude fall, there is a great potential safety hazard

[0004] At present, the special tool for high-voltage test is the high-voltage test rod. When in use, the high-voltage test line is directly clamped or connected to the top of the hitch rod, but the top is not easy to fix, and the test effect may be affected by poor contact, or the test line is too long to easily Make the test line fall off or float up in windy weather, resulting in personal electric shock or equipment short circuit accident
