Abstract

The embodiment of the invention provides a dual-mode current collecting system and method. The system comprises an alternating current-direct current pantograph, an alternating current-direct current voltage transformer, an alternating current-direct current change-over switch, a direct current circuit, an alternating current circuit and a switching controller. The alternating current-direct current voltage transformer is connected with the alternating current-direct current pantograph. The alternating current-direct current change-over switch is connected with the alternating current-direct current pantograph and the direct current circuit or the alternating current circuit. The switching controller is connected with the alternating current-direct current voltage transformer and the alternating current-direct current change-over switch. Both the direct current circuit and the alternating current circuit are connected with a traction converter. The switching controller is used for acquiring whether received voltage is an alternating current or a direct current and controlling the alternating current-direct current change-over switch to be connected with the direct current circuit or the alternating current circuit according to acquisition results, so that the direct current or the alternating current is provided for the traction converter. The dual-mode current collecting system and method can be suitable for train tracks in an alternating current mode and a direct current mode at the same time, and the operation range of a train set is expanded.

Description

technical field [0001] The invention relates to a train set current receiving technology, in particular to a dual system current receiving system and method. Background technique [0002] With the economic growth and the change of the economic structure, the construction and development of cities are becoming more and more fast, more and more cities have subway lines, and there are more and more intercity lines between cities. The construction of rail lines further enhanced the rapid development of the city. [0003] The existing intercity lines are not connected to the intra-city subway lines. The EMUs in the intercity lines receive the 25kV / 50Hz AC power provided by the AC high-voltage catenary through the AC pantograph; The pantograph receives 1500V DC power from the DC catenary. [0004] Because the power supply network of the intercity line and the subway line in the city are different, the EMU and the train set are equipped with different high-voltage current-receivi...
