本发明公开了一种接触网中性段融冰过程防熔断检测与中性段放电方法,具体为:列车运行状态监控预警模块通过传感器监测周边供电臂的列车行驶状态,在列车来临时做出预警,当无列车时,启动开关控制系统开始融冰;吊弦防熔断检测模块在融冰过程中,通过检测承力索和接触线电流差值获得吊弦电流的范围,确保融冰过程吊弦的安全;中性段接地放电装置在除冰后使用真空断路器将中性段接地放电。本发明有效的增加接触网除冰范围、确保融冰过程不会对接触网系统造成熔断危害和保障供电系统稳定性。

    The invention discloses an overhead line system neutral section ice melting process anti-fusing detection and neutral section discharging method which specifically comprises the steps that a train running state monitoring and early warning module monitors the train running state of peripheral power supply arms through a sensor, early warning is conducted when a train comes, and when no train exists, a switch control system is started to start ice melting; the dropper anti-fusing detection module obtains the current range of the dropper by detecting the current difference value of a carrier cable and a contact line in the ice melting process, so that the safety of the dropper in the ice melting process is ensured; and the neutral section grounding discharge device is used for grounding and discharging the neutral section by using a vacuum circuit breaker after deicing. According to the invention, the deicing range of the overhead line system is effectively increased, the melting damage to the overhead line system in the deicing process is avoided, and the stability of a power supply system is guaranteed.
