Background
The direct current reference voltage and leakage current test of the lightning arrester is the most important handover, routine and diagnosis test item of the lightning arrester, and has important significance for finding that the internal insulation of the lightning arrester is affected with damp and aged, and serious partial discharge exists.
Because the direct current reference voltage of the lightning arrester is generally higher, for example, the direct current reference voltage of each section of the 220kV lightning arrester is generally about 150kV, and the direct current reference voltage of each section of the 500kV lightning arrester can be generally about 200 kV. However, the insulation of the high-voltage lead wire of the current lightning arrester direct-current reference voltage and leakage current test is generally low, so that how to arrange the high-voltage lead wire in the test project is very important work, and the work sometimes takes a lot of time, especially for occasions where field devices are installed highly and are close to the ground, and the high-voltage lead wire is not easy to arrange. For example, the direct current reference voltage and leakage current test are carried out after the lightning arrester on the tower is installed, and because the structure is more complicated on the tower, the number of grounded metal parts is more, and equipment such as an insulating support porcelain insulator and a cable head also exist simultaneously, so the following problems exist when the direct current reference voltage and leakage current test of the lightning arrester on the tower is carried out:
1. in order to keep enough safe distance between the high-voltage lead and the grounding part, the insulating support porcelain insulator, the cable head and the like of the tower, the position and the wiring mode of the high-voltage lead need to be repeatedly adjusted, and each phase of lightning arrester test needs to carry out the work, so that the workload of test personnel is greatly increased, the working efficiency is reduced, and the timely operation of equipment is not facilitated;
2. at present, when a direct-current high-voltage lead is arranged, an insulating adhesive tape is usually used for suspending the high-voltage lead on a grounding metal part or winding the high-voltage lead on an insulating porcelain insulator, and then the trend of the high-voltage lead is adjusted;
3. when carrying out the hoist and mount of high voltage lead wire or twine high voltage lead wire on the insulator with the insulating tape, the testing personnel often need stand and carry out work at the most marginal of platform above the shaft tower, and this has increased the risk that testing personnel takes place the high altitude and fall undoubtedly, and the test work of arrester is gone on at night in the shaft tower very many times especially, and consequently testing personnel's sight can be very fuzzy, and energy is also more easily dispersed, so arrange the work time taking place the high altitude accident of falling more easily carrying out high voltage lead wire.
