摘　　要：针对电网实际运行中由于变压器压力释放阀的质量问题导致的事故,建立了一套适用于不同规格压力释放阀的数字式测试系统,介绍了其工作原理以及性能。实践证明,该系统可验证变压器压力释放阀的质量,能及时诊断出有缺陷的压力释放阀,减少了电网的事故隐患。According to accidents caused by disqualification of transformer pressure relief valve in power systems operation, a series of digital test systems were developed to suit for different pressure relief valves. Also the working principle and performance of this system were introduced. And through practice, it was identified that this system could check the quality and diagnose the flaw of transformer pressure relief valve, thus reduce hidden perils of power system.
