Problems solved by technology

In the process of carrying out live testing of capacitive equipment, we often encounter the dilemma of low ergonomics caused by mismatched or unequipped test aids
For example, in the live test of transformers and arresters, the leakage current test wiring rod is too high, the test point is coated with anti-corrosion paint, the corrosion is serious and cannot be short-circuited, and it is impossible to observe whether the contact point is reliable, etc., resulting in inaccurate testing and misjudgment of abnormal data. , low work efficiency, and the existence of operational safety risks; carrying out transformer vibration tests due to insufficient height, the sensor cannot be placed on the upper part of the main transformer oil tank, resulting in large errors in test results and unstable data.

Abstract

The invention discloses a convenient-to-use live test auxiliary tool, which comprises a shell assembly and an adjusting assembly, and the shell assembly comprises a rectangular opening, and the adjusting assembly comprises a first supporting rod, a second supporting rod, an angle adjusting part and a height adjusting part. According to the device, through three sets of shell assembling auxiliary tools, internal elements are convenient to assemble, disassemble and replace, and the service life of the device is prolonged; the auxiliary tool can be matched with different equipment conveniently byadjusting the height through the height adjusting part, the angle of the first supporting rod is adjusted through the angle adjusting part, the equipment on the first supporting rod is adjusted to reach the proper working distance from the tested equipment, and the equipment is convenient to use. The height and the angle can be adjusted only through the first rotating column, operation is easy and convenient, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of live work testing, in particular to an auxiliary live test tool that is easy to use. Background technique [0002] At present, Guiyang power grid covers about 110 substations with a voltage level of 110 kV and above. According to statistics, the testers conduct electrification tests on capacitive equipment such as main transformers, lightning arresters, and transformers in substations every year. They need to complete more than 150 substation electrification tests and more than 5,000 sets of main network equipment electrification tests throughout the year. Work. Through a variety of live tests to ensure the safe and reliable operation of the main network equipment, and effectively enhance the level of insulation technology supervision of the grid equipment, and improve the reliability of the grid power supply. In the process of carrying out live testing of capacitive equipment, we often encounter the di...
