Study on (1) overvoltage. In addition to AC or DC working voltage, power equipment will encounter lightning overvoltage and internal overvoltage, which will bring serious harm to the insulation of power equipment. Therefore, it is necessary to study the occurrence and variation of overvoltage and the technical measures to prevent accidents caused by overvoltage.

(2) Research on high voltage testing technology. In order to study insulation and overvoltage problems, it is necessary to carry out various high-voltage tests, so it is necessary to study test methods and measurement technologies and develop various high-voltage test equipment.

(3) Study on pollution flashover of electric porcelain.

brief introduction

High-voltage electricity technology is applied to power transmission, because the higher the voltage, the smaller the current, so that high-voltage electricity transmission can reduce the current during power transmission, thereby reducing the heat loss caused by current and reducing the material cost of long-distance power transmission.

It is an important content of high voltage technology to study the insulation characteristics, dielectric strength and discharge mechanism of dielectric under various applied voltages in order to solve the insulation structure problems of electrical equipment reasonably.
