Analysis on the causes of node heating, forewarn and countermeasure of electrical equipment in high voltage distribution network

Abstract

Heating of electrical equipment nodes in high-voltage distribution network will lead to a series of problems. It is of great practical significance to explore the causes of heating of electrical equipment nodes, and to study the early warning methods and Countermeasures of electrical equipment nodes. This paper discusses the causes of the heating of electrical equipment nodes, analyzes the causes of the increase of contact resistance, studies the heating early warning technology of electrical equipment nodes with a heating early warning device of distribution network equipment nodes as an example, and finally expounds the countermeasures to deal with the heating of electrical equipment nodes based on the application of temperature measurement technology and the implementation of temperature testing measures.
