摘　　要：针对三相交流道岔动作电路在室外转辙机发生断相后断相保护继电器不落的问题,通过对在正常工况和断相工况下不同场景现场测试结果的深入研究,以及对模拟式断相保护器和数字式断相保护器工作原理的详细分析,揭示多源分布电容对动作电路影响的内在发生机理,提出工程化改善措施和对行业标准的修改建议。The phase interruption protector relay of a three-phase AC switch transition circuit is not deenergized after the loss of phase occured in an outdoor switch machine.In order to solve this problem,the internal mechanism of the infl uence of the multi-source distributed capacitance on this circuit is revealed through the in-depth study on the fi eld test results in diff erent scenarios under both normal and loss-of-phase conditions,and through the detailed analysis of the working principles of the analog phase interruption protector and the digital phase interruption protector.Moreover,the measures for engineering improvement and suggestions on how to modify the industry standard are put forward.
