500kV电气设备不拆线进行预防性试验的研究

Study on the Preventive Test for 500kV Electrical Equipment of no -Removing the Lead Line

根据对500kV电气设备停电时不拆一次引线进行预防性试验的研究,在取得大量实测试验数据的基础上,通过拆线和不拆线试验数据的对比分析,给出了不拆线时500kV电气设备的试验结线和参考标准,这一研究成果对缩短500kV电气设备的停电时间,减轻试验强度,提高设备及人员的安全有着重要的现实意义。

Based on the study of the preventive test of no - removing the primary lead line for 500kV electrical equipment which its power source is cut off,a vast amount of measured data were collected. By the comparative analysis between the test data of removing and no-removing the lead line,the connection and the reference criterion of 500kV electrical equipment of no - removing the lead line were given. Teh research result will be of momentous current significance for shortening the time of the power cutting off,reducing the test intensity and improving the safety of the equipment and operation personnel.
