Description

Technical Field

[0001] This utility model belongs to the technical field of resistance box testing, and more specifically, it relates to a comprehensive test bench for subway train braking resistance boxes. Background Technology

[0002] The braking resistor box is an important component of the electric braking system of subway trains. Under braking conditions, the traction motor outputs electrical energy to feed back to the power grid. If the power grid cannot consume the fed-back electrical energy, the braking resistor converts the excess electrical energy into heat energy and releases it. During the maintenance of the braking resistor, a series of tests need to be performed on the components to ensure the normal operation of each component.

[0003] Based on the above, most existing testing methods for braking resistor boxes have many shortcomings. Traditional testing uses connection methods such as alligator clips, which are inconvenient to operate and prone to errors. There is a lack of effective means to detect the airflow direction of the braking resistor fan, and incorrect fan rotation may lead to poor heat dissipation of the braking resistor. Test data mostly rely on manual recording and judgment, which is inefficient and prone to errors. Utility Model Content
