| Abstract: | The turnout starting circuit of ZYJ7 type point machine in railway speed-increasing section is improved,and an integrated phase breaker(DBQ)with time-delay breaking function is designed to cut off the motor starting circuit at the specifi ed time,so as to prevent the turnout action not to be in place due to failure,no indication after in place and jamming phenomenon.It can save a time relay and simplify the starting circuit in accordance with the fail-safe principle. |
