有载调压开关切换顺序试验

Transfer sequence test of on-load voltage regulation switch

切换开关质量的好坏对能否保证有载调压开关的安全运行起着决定性的作用。以双电阻切换开关切换过程试验为例,介绍了切换开关的切换顺序及试验过程,指出了在试验过程中应注意的问题。通过示波图分析切换开关在试验过程中的电流波形,以此对切换开关的性能进行分析。多年的实践已经验证,通过切换试验鉴定切换开关的切换顺序,如果切换顺序和各项性能指标符合设计要求就可以间接判断其切换能力,验证切换开关的质量,确保投入使用的开关质量符合要求。

The quality of transfer switch has crucial effect on the safe operation of on-load voltage regulation switch. With a dual-resistance transfer switch as example,the transfer sequence and test process are introduced. Cautions during test are pointed out. The performance of transfer switch is analyzed based on the test current waves displayed on oscillograms. The transfer sequence of the transfer switch can be appraised by transfer test：if all performance indices meet the design requirements,its transfer capability can thus be ensured ,which is proved by years ＇practices.
