发电厂非电量保护技术工作分析

Technical Work Analysis of Power Plant Non-electrical Protections

非电量保护与电量保护共同构成了发电厂发电机、变压器等主设备的电气保护。但在实际应用中非电量保护没有得到足够的重视,许多保护的设置没有按照规程的规定来执行。通过分析实际发生的案例、整理规程中对非电量保护的规定、分析非电量保护的二次回路,希望对发电厂非电量保护的管理工作有所帮助。

The power plant generator and transformer＇s relays are composed of both non-electrical and electrical protections. Engineers pay less attention to non-electrical protection on daily work. Many non-electrical protections are set incorrectly according to the specifications. In this paper,by analyzing an actual accident, compiling the regulations of non-electrical protection, analysis of non-electrical protection secondary circuit, we hope it will be helpful to non-electrical protection management work.
