It is necessary to check the lightning protection device that pollutes the surface of the pottery in the actual operation. Because the surface of the pottery is polluted seriously, the working voltage is very uneven. When a working voltage is increased, the amount of current in the separation resistor will greatly increase, and you are likely to be burned and cause common faults, resulting in a series of capacitors in series and a high-voltage arrester. In addition, it is very likely that the arc characteristics of the valve arrester will continue to be compromised. Therefore, when the shaft sleeve of the high-voltage arrester is relatively serious, the dust on the surface must be removed immediately.

Check the case clues of the high-voltage arrester and the lead-in wire of the grounding device, there are burn marks and broken strands, and whether the charging and discharging recording equipment is scalded. According to the inspection of these aspects, the hidden shortcomings that are most easily found are the high-voltage arresters; check the top of the high-voltage arresters It depends on whether the tightness is good. The poor tightness of the high-pressure arrester can easily lead to safety accidents. Therefore, the porcelain sleeve and the way that the dark blue concrete should be checked are inseparably connected to the upper collar of the 10,000 v valve arrester. It is possible to add a moisture-proof cover to prevent rain; check whether the distance between the high-voltage arrester and the electrical equipment of Zhijian meets the requirements,

The high-voltage arrester should be used as the surrounding electrical equipment to be protected. The high-voltage arrester should check and record the posture of the equipment after a storm; check the leakage current, and the staff's DC charging and discharging working voltage should exceed or fall below the index value. It should be maintained and tested ; The actual operating time of the charging and discharging recording equipment is too much, which should be maintenance; the porcelain sleeve and the concrete are cracked together; the flange and the rubber plate are damaged, and the maintenance project should be carried out. Should be maintained regularly.
