- Abstract
Electrical power connector is generally a weak link in the power system, which is probably the most frequent source of detriment to the overall performance of a power system. In order to solve overheating of connector authors surveyed many substations in service and analyzed the deterioration mechanism. We found that the main overheating spots have been concentrated on clamps, bus-bus joint, isolation switch, etc. Based on service condition and ambient environment of equipment, connector overheating was investigated from aspects of corrosion, fretting, great loads, etc. Coated with electrical joint compound is one of control techniques. The performance of electrical joint compound was examined by testing, and its long-term service condition was tracked. The electrical joint compound can effectively resolve the overheating defects in electrical contact, because it not only decreases the contact resistance and the temperature-rise degree, but also improves the corrosion resistance. By comparing the success of using qualified electrical joint compound with the failure of using inferior electrical joint compound, electrical joint compound must be carefully selected and subject to strict inspection before putting into service.
