Abstract

The invention discloses a locomotive traction converter test apparatus and a method thereof. The apparatus comprises: a power assessment power supply, a charging and discharging loop, a secondary filter circuit, a locomotive simulation power supply, an impedance load, a traction converter, a cooling system, an inverter impedance load and a measurement and control system. The power assessment power supply is connected with the charging and discharging loop. The charging and discharging loop is connected with the secondary filter circuit. The charging and discharging loop and the secondary filter circuit are connected with the traction converter respectively. An output terminal of the locomotive simulation power supply is connected with the impedance load and the traction converter respectively. The output terminal of the traction converter is connected with the inverter impedance load. The traction converter is connected with the cooling system and the measurement and control system respectively. The test method comprises: a chopper loop test, a light load joint debugging test and a power assessment test of the traction converter. By using the technical scheme in the invention, the comprehensive performance test can be performed to the locomotive traction converter. A structure is simple. An operation is simple. And environmental protection and energy saving can be achieved.

Description

technical field [0001] The invention relates to a locomotive test bench device and a method thereof, in particular to a locomotive traction converter performance test bench device and a method suitable for locomotive vehicles. Background technique [0002] As the heart of the locomotive, the traction converter determines the performance of the locomotive such as starting, running, braking and maximum operating speed. The development of locomotive and rolling stock technology is concentrated on the development of traction converters, but there is no performance test bench for locomotive traction converters to provide analog signals and analog power supplies for locomotive traction converters. and simulated loads to carry out performance tests on locomotive traction converters. [0003] Sany Electric Co., Ltd. applied on December 25, 2009, and published on June 16, 2010. The Chinese invention patent application with the publication number CN101738553A, "A Universal Test Syste...
