高压直流电阻分压器径向放电现象的研究及改进措施

摘要

从高压直流电阻分压器的运行特性、结构原理出发，介绍了径向放电的概念、产生机理及危害，给出了径向电位差的数值估算方法，提出了减小径向放电危害的具体措施并将其应用于产品设计中，提高了高压直流电阻分压器设备运行的可靠性。%Starting from operation features of high-voltage DC resistor divider and its structure principle, this paper introduced the concept of radial discharge, generation mechanism and harm, giving the value estimation method of radial potential difference. Actual measures to reduce radial discharge harm were raised and applied in products design, which improved the reliability of high-voltage DC resistor divider equipment operation.
