Abstract

The invention particularly relates to a hybrid railcar traction system, and aims to solve the problems that the conventional hybrid railcar traction system is complex in switching, inconvenient to operate and low in utilization ratio. The hybrid railcar traction system adopts the structure that a diesel generator set is connected to a rectifier; the rectifier, a normally-closed contact of a power change-over switch, a contactor set, a direct current traction motor set, and a normally-closed contact of a direction change-over switch are sequentially connected in series; a traction accumulator battery, a fuse, a direct current contactor, a smoothing reactor, a normally-open contact of the power change-over switch, the contactor set, the direct current traction motor set, a normally-open contact of the direction change-over switch, and a chopper are sequentially connected in series; the output end of a driver controller is respectively connected with the input ends of a constant-power excitation controller, the chopper and the direction change-over switch; the output end of the constant-power excitation controller is connected with the input end of the diesel generator set; the output end of a power select switch is connected with the input end of the power change-over switch. The hybrid railcar traction system has the advantages of simplicity and convenience in operation, and high utilization ratio of vehicle-mounted equipment.

Description

technical field [0001] The invention relates to rail vehicle traction technology, in particular to a dual-power rail vehicle traction system. Background technique [0002] With the gradual improvement of people's environmental protection requirements, some road sections require rail cars to run with zero emissions, low noise, quietness and stability. , the internal combustion rail car just meets the requirements of these road sections; the dual-power rail car with a diesel generator set and a battery pack at the same time meets the needs of users. [0003] However, there is currently no dual-power rail car traction system matching it, and there are often problems such as complicated power switching, inconvenient operation and low utilization rate. Contents of the invention [0004] In order to solve the problems of complicated switching, inconvenient operation and low utilization rate in the existing dual-power rail car traction system, the present invention provides a du...
