Abstract

The invention provides a test system for a metro traction system and a method. The test system for the metro traction system comprises a rectifier cabinet, wherein the rectifier cabinet accesses external high-voltage alternating current; the body of the rectifier cabinet comprises a rectifier bridge, a discharge resistor, a capacitor, a buffer resistor, a vacuum contactor, a high-voltage relay, an air switch, a fuse and a contactor; the bottom wall of the body of the rectifier cabinet is connected with the top wall of a cuboid stainless steel base arranged on the ground. The problems that working performance of the conventional rectifier cabinet is affected by shaking of devices in the rectifier cabinet under the action of external vibration and even the devices are destroyed, the manufacture cost is increased, the assembly accuracy is low and the visual effect is poor in the prior art are effectively solved in combination with the method.

Description

technical field [0001] The invention relates to the technical field of subway testing, in particular to a testing system and method for a subway traction system. Background technique [0002] As a train power system, the traction system has extremely high requirements on safety and reliability. The product must undergo rigorous testing from research and development to production and delivery. From the component level, functional component level, module level to the final system level, each layer of testing must Indispensably, the traction products of mainstream traction system suppliers at home and abroad are verified through routine tests or type test platforms to verify equipment functions and reliability. The test platforms are complicated, the utilization rate of personnel is low, and the initial construction and maintenance costs are extremely high. Greatly increased the threshold for emerging manufacturers to enter related fields. [0003] To avoid such problems, a hi...
