Auxiliary power supply device of guide rail electric locomotive, guide rail electric locomotive and power supply method of guide rail electric locomotive

Abstract

The invention provides an auxiliary power supply device of a guide rail electric locomotive, the guide rail electric locomotive and a power supply method of the guide rail electric locomotive, and solves the problems that existing auxiliary power supply equipment is large in size, inconvenient to maintain and detach, few in functions and high in manufacturing cost. The auxiliary power supply device comprises a central controller module, a preceding-stage voltage stabilization module, a high-frequency inversion module, a high-frequency DC/DC module, a main contactor and a storage battery. The central controller module is in communication connection with a locomotive driver cab, the preceding-stage voltage stabilization module, the high-frequency inversion module and the high-frequency DC/DCmodule and is electrically connected with the main contactor. The input end of the preceding-stage voltage stabilization module is electrically connected with a pantograph-catenary of the guide railelectric locomotive, and the output end of the preceding-stage voltage stabilization module is electrically connected with the input ends of the high-frequency inversion module and the high-frequencyDC/DC module; the output end of the high-frequency inversion module is electrically connected with a first locomotive load needing alternating current through a main contactor; the output end of the high-frequency DC/DC module is electrically connected with a second locomotive load needing direct current and the storage battery; and the storage battery is used for supplying power to the central controller module.

Description

technical field [0001] The invention belongs to the power supply technology of a guide rail electric locomotive, and in particular relates to an auxiliary power supply device for a guide rail electric locomotive, a guide rail electric locomotive and a power supply method thereof. Background technique [0002] With the continuous improvement of living standards and the continuous development of the transportation system, electric locomotives have gradually become one of the main means of transportation in large and medium-sized cities. As the core component of subway vehicles, the auxiliary power system of subway vehicles is an indispensable and important system components. In recent years, due to environmental pollution, the country has vigorously promoted electric clean energy, so guide rail cars have developed rapidly in recent years. Due to the various installation forms and high volume requirements of electric guide rail trams, higher requirements are placed on power su...
