摘　　要：柴油发电机在厂用电系统中扮演着极为重要的角色,为检验柴油发电机启动性能的可靠性,需要定期做空载启动和带载启动试验。针对柴油发电机空载启动试验中出现的非同期合闸事故,发现了其控制回路中相关开关接点设计存在的问题并提出了更改方案。Diesel generator plays an important role in power plants. In order to testify its reliability,the no-load start tests and load start tests are need to be done periodically. In view of the non-synchronization current breaker closing accident of the no-load start tests,some problems on the switch design of the control circuits were founded and improved projects were put forward.
