一种绝缘故障定位用信号发生器的设计与应用

摘要

在隔离电源系统中，为防止由于多点接地引发严重后果，需实时对系统进行对地绝缘监测，并在监测到对地绝缘故障时，进行故障定位。本文在介绍绝缘定位用信号发生器工作原理的基础上，详细阐述了信号发生器的硬件和软件设计。本文中设计的产品已通过试验检验，可应用于IT系统，为应用场所提供安全可靠的供电解决方案。%In the isolated power system, in order to prevent serious consequences caused by multi-point grounding, real-time monitoring of the insulation system is needed, and fault location when monitoring the insulation fault. This paper describes the design of the hardware and software of signal generator based on the works of positioning signal generator insulation. The product has passed the experimental test that can be used in IT systems;provide safe and reliable application site powered solutions.
