Abstract

Abstract:

Firstly， the current overall situation and features of power equipment overheating were summarized， the basic theory and research progress of electrical contact were introduced， and then some specious understandings of electrical contacts were clarified. Secondly， combined with the service condition and natural environment of power transmission and transformation equipments， the deterioration mechanism and synergistic reaction of electrical contact element were discussed from aspects of corrosion （galvanic corrosion， electrical damage and oxidation corrosion）， temperature factor and fretting. Finally， the current problems existed in electrical contact technology and construction in the power system were discussed， and some suggestions were proposed for the reliability improvement of electrical contacts.

Key words: power grid, electrical contact, electrical connection, overheating, deterioration mechanism
