High-rating generator load testing method

Abstract

The invention discloses a high-rating generator load testing method. A high-rating generator load testing device and a driving motor are used for testing a load for a testing generator; the high-rating generator load testing device includes a bracket, a supporting assembly and an axle seat assembly, wherein the axle seat assembly is arranged and fixed on the bracket, and the supporting assembly isarranged in the bracket; the high-rating generator load testing method includes the steps that the testing generator is arranged on the supporting assembly, and a rotor and a stator of the testing generator are coaxially fixed to the axle seat assembly; the testing generator is fixedly connected with the bracket; the driving motor is connected with the axle seat assembly in a transmitting mode; and the driving motor is started, the axle seat assembly transmits power to drive the rotor of the testing generator to rotate, and the testing generator is tested the load. According to the high-rating generator load testing method, load testing of the testing generator is realized, accuracy and reliability of testing are improved, butting of the testing generator and the axle seat assembly is realized quickly and accurately, and loading testing for the testing generator with the different models is realized.

Description

Technical field [0001] The invention relates to a load test method for a large generator, which is used for the load test of a large generator. Background technique [0002] At present, large-scale mining trucks adopt the mode that the driving motor directly drives the wheels. The power transmission from the generator to the driving motor is realized by the generator directly connected to the engine. Due to the large horsepower, the power of the generator is also very large, all above 1000KW, and the maximum weight is 5 tons. Therefore, when the performance test of the generator is carried out, a series of large, heavy and difficult problems such as driving, installation, and fixing are involved. . [0003] Moreover, the structure of the generator of a large-sized truck is different from that of an ordinary generator. The rotor only has a bearing seat at the back end, and there is no bearing seat at the end of the engine. When the main engine is installed, the front end of the gen...

Problems solved by technology

[0008] In the prior art, there is no device or method specially designed for load testing of generators of large-loaded trucks. Load testing of generators of large-loaded trucks requires the transmission power of the external drive motor to be effectively transmitted to the rotor of the generator of large-loaded trucks. In addition, it is necessary to ensure that the large-scale loaded truck generator will not generate redundant vibrations during the test, which will affect the accuracy of the test. Different types of generators have different dimensions, so before testing, it is also necessary to adapt to different types of generators due to the external dimensions and installation. and variations in assembly dimensions caused by manufacturing errors
