Abstract

The invention discloses a test system and method for alternating current transmission of a complete vehicle with electric wheels. The system includes: a system to be tested, which is used to test the power characteristics of a diesel engine, the braking capacity of a braking resistor cabinet, the performance of a converter, and the characteristics of a motor. Unit component performance test, and the matching performance test of multiple unit components including main control regulation, excitation regulation and motor control, including sequentially connected diesel engines, generators, tested converters, test cabinets and tested motors, And the brake resistance cabinet and traction / brake pedal connected to the tested converter; the accompanying test system is used to cooperate with the tested system to complete various performance tests, and includes the accompanying test motor and the accompanying test converter connected in sequence and three-phase adjustable power supply. The tested motor is connected with the test motor through a coupling. The invention can solve the technical problems that the ex-factory test of the existing AC electric wheel complete vehicle components is insufficient and incomplete, the performance matching of the complete vehicle components cannot be tested, and the test process is time-consuming and laborious.

Description

technical field [0001] The invention relates to the field of converter technology, in particular to an electric drive test system and method applied to an AC drive mine dump truck. Background technique [0002] In order to solve the shortcomings of traditional mechanical transmission mining dump trucks, such as large load, easy damage, high maintenance cost, and large vehicle space, more and more large mining dump trucks have adopted AC drive control systems. The AC drive dump truck uses a high-power traction motor to replace the traditional mechanical transmission, which reduces a large number of gear transmission units and mechanical wear, brings greater flexibility to the vehicle space design, and improves the operating efficiency of the entire life cycle. However, when designing a complete vehicle with AC electric wheels, each component will have a factory test, but the test may not be sufficient and perfect. In the end, the performance of the complete vehicle can only b...
