The invention relates to an overhead line system insulation anchor section joint anti-fusing device and a direct current contactor control method, and relates to the field of rail transit auxiliary instruments, and the overhead line system insulation anchor section joint anti-fusing device comprises an anti-fusing primary assembly, a monitoring assembly and a train state acquisition assembly. The anti-fusing primary assembly comprises a direct current contactor, a voltage detection unit and a current detection unit, and can carry out corresponding arc extinction operation. The monitoring assembly comprises a monitoring unit, a display unit and a communication unit, and can perform corresponding data monitoring, acquisition and instruction sending operations. The train state collecting assembly comprises a plurality of photoelectric sensors and speed measuring radars, and the photoelectric sensors and the speed measuring radars can collect and feed back the speed and position information of the corresponding trains. The anti-fusing primary assembly and the train state acquisition assembly are communicated with the monitoring assembly through wiring cables, and the monitoring assembly is in communication connection with a substation integrated automation background. According to the device for preventing fusing of the insulation anchor section joint of the overhead line system and the corresponding direct current contactor control method, when an electric passenger car stops in the insulation anchor section joint area, the two sides of a fracture of the insulation anchor section are automatically short-circuited, most of the through current of the overhead line system is shunted to a short-circuit bypass of the device, fusing of the insulation anchor section joint is avoided, and the service life of the overhead line system is prolonged. And power supply safety and operation stability are improved.

    本发明涉及一种接触网绝缘锚段关节防熔断装置及直流接触器控制方法,涉及轨道交通的辅助器械领域,包括防熔断一次组件、监控组件和列车状态采集组件。防熔断一次组件包括直流接触器、电压检测单元和电流检测单元,可进行相应的消弧作业。监控组件包括监控单元、显示单元和通讯单元,可进行相应的数据监控、采集与指令发送作业。列车状态采集组件包括光电传感器和测速雷达,且光电传感器与所述测速雷达均为多个,可进行相应列车的速度及位置信息进行收集与反馈。防熔断一次组件与列车状态采集组件均通过接线线缆与所述监控组件相连通,监控组件与变电所综合自动化后台通讯连接。本发明接触网绝缘锚段关节防熔断的装置并配合相应的直流接触器控制方法,可使电客车停在绝缘锚段关节区域内时,自动短接绝缘锚段断口两侧,使接触网的穿越电流大部分分流至装置短接旁路,避免绝缘锚段关节熔断,提高供电安全与运行稳定性。
