基于电晕放电原理的电动机特性研究

RESEARCH ON MOTOR CHARACTERISTICS BASED ON CORONA DISCHARGE PRINCIPLE

在电极两端施加高压时,电极附近的气体介质就会被局部击穿而产生电晕放电现象,这在曲率半径特别小的电极上尤为明显。电晕放电在除尘器、高速打印机等装置上有较广的应用,但在高压输电等特殊场合也带来不利影响。因此,研究高压放电电晕的放电规律及放电特性具有重要的研究意义。本文采用控制变量法,主要通过改变高压电动机的定子个数、电极倾角、电极间隙等系列参数,对高压电动机转子转速的变化进行系统研究,进而探究电晕放电现象的影响因素。论文对高压电动机的设计和电晕现象的防范具有指导和借鉴意义。

When high voltage is applied to both ends of the electrode,the gas medium near the electrode will be partially penetrated,resulting in a corona discharge,which is especially apparent to electrodes with a particularly small radius of curvature.Corona discharge is widely used in dust collectors,high-speed printers and other devices,but it also brings adverse effects in special occasions such as high-voltage power transmission.Therefore,it is of great significance to study the discharge law and characteristics of high voltage corona discharge.In this paper,the control variable method is used to study the variation of the rotor speed of the high-voltage motor by changing the series parameters such as the number of stator,the electrode inclination angle and the electrode gap,and then the influencing factors of corona discharge phenomenon were investigated.This paper is of guiding and referential significance to the design of high-voltage corona motor and the prevention of corona phenomenon.
