Test system and test method for insulation safety equipment for extra-high voltage live working

Abstract

The invention provides an ultrahigh-voltage live-working insulation safety instrument test system and method. The test system comprises an ultrahigh-voltage live-working insulation safety instrument test hanging device (5), a set of insulation rod arc iron clamp test electrodes (6) hung on the hanging device and used for clamping objects (9) to be tested, infrared intelligent high-voltage test protection systems (1) arranged at the periphery of the position below the hanging device and provided with the wireless monitoring function, a test data remote collection device (2) and a leakage current centralized measuring device (4), wherein the test data remote collection device (2) and the leakage current centralized measuring device (4) are arranged below the hanging device and in the ultrahigh-voltage test electric field environment, a power frequency testing transformer and an impulse voltage generator, wherein the power frequency testing transformer and the impulse voltage generator are arranged on the two sides of the position below the hanging device respectively, and ultrahigh-voltage test rotary telescopic electrodes arranged at the top ends of the power frequency testing transformer and the impulse voltage generator respectively. By means of the system and method, multiple objects to be tested can be tested at a time, test efficiency is high, the test is safe, and the human input on the aspect of safety protection in the test process can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of withstand voltage tests of insulation safety tools for live work. Background technique [0002] Electric energy has become an indispensable energy source in the daily life and industrial production of human society, and electric energy is also an extremely important resource.

In the operation, maintenance and repair tests of power systems, live work is often required. In order to ensure the personal safety of operators in live work, rod-shaped live work insulation such as insulating operating rods, grounding operating rods, and electric inspection operating rods should be used. Safety tools and insulating rope tools. According to the requirements of GB26860-2011 and DL / T976-2005 regulations, this kind of insulating safety tools must be tested every year, and the number of tests is large.

The existing test method is to set up a horizontal hanging rod, install pressure equalizing balls at both ends of the hanging rod, and then hang the tested product on the hanging rod for testing, because the test regulations require that there be at least With a distance of 50cm, the number of tested objects suspended at one time cannot be too much, and the test efficiency is very low; the pressure equalization effect is also very poor, and the corona sound is very loud during the test, which will cause great psychological pressure on the test operators. ;When carrying out projects that require leakage current testing, we can only use very long wires to guide the leakage current of each tested product to a safe area far away for observation and recording. The wiring is quite cumbersome and time-consuming; when changing the test item It is necessary to climb to the high altitude to replace the test electrodes, which requires high-altitude operations and increases the risk of the test operators; the test site does not have a safety protection system, and a large amount of manpower must be invested in the test to ensure the safety of the test
