| 摘要: |
| 提出了一种用集成电路构成的新型电气设备断相保护，当电力系统中的各种主设备，断路器以及电动机等发生相断相故障时，能动作发出信号，必要时亦可协作跳闸，保护装置由三个高灵敏度的电流元件和相应的逻辑回路组成，接线简单，工作可靠，对防止电气设备由于一相或两相接通而引起的烧毁事故具有重要作用。 |

| Abstract: |
| An IC type phase failure protection is used to protect phase failure fault of generator,transformer,breaker,motor,etc.,which can give a trip signal.The protection consists of three high sensitive current relays and relevant logic circuit.The system wiring is easy and the reliability is high.It can avoid fatal accident caused by switching on one or two phases of electric equipment. |
| Key words: phase failure protection,electric equipment,motor protection |
