Abstract

The invention relates to a pantograph detection circuit, a ground split-phase passing device and a control method. The pantograph detection circuit comprises a boosting cable and a sensor. The boosting cable is used for sending current of a steel rail corresponding to the position where a pantograph is located into a return cable when the pantograph draws electricity through a contact line. The sensor is electrically connected with the boosting cable and is used for outputting a detection signal to the ground split-phase passing device when detecting that the electric signal in the boosting cable exceeds a signal limit value, the detection signal is used for indicating the position information of the pantograph. The sensor is connected into the boosting cable to detect the electrical signal in the boosting cable and output the corresponding detection signal to the ground split-phase passing device. The aim that the ground split-phase passing device can know the specific position of thepantograph is achieved, shortening the length of a neutral section is facilitated, the phase change power-off time of a train is shortened, the speed loss is reduced, and the running efficiency of the train is improved.

Description

technical field [0001] The invention relates to the technical field of electrified railways, in particular to a pantograph detection circuit, a ground over-phase separation device and a control method. Background technique [0002] With the development of electrified railway technology, railway transportation has made unprecedented progress. The catenary of the electrified railway can adopt single-phase power frequency AC power supply mode, and in order to reduce the voltage unbalance of the three-phase power supply network of the power system and improve the utilization rate of the power grid, the electrified railway adopts segmented and phase-separated power supply, that is, in different phases of voltage An unpowered neutral zone is embedded between the two supply arms. The anchor segment joints are used to make a smooth transition between each power supply arm and the neutral zone. In the operation of electrified railways, in order to reduce the adverse effects of cate...
