Description

technical field

[0001] The invention relates to a large-scale generator load testing method, which is used for the load test of the large-scale generator. Background technique

[0002] At present, large-scale mining trucks use the mode that the drive motor directly drives the wheels, and the power transmission from the generator to the drive motor is realized by the generator directly connected to the engine to provide power. 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 performing a performance test on the generator, it involves a series of large, heavy, and difficult problems such as driving, installation, and fixing. .

[0003] Moreover, the structure of the large-scale loading truck generator is different from that of ordinary generators. The rotor is only designed with a bearing seat at the rear end, and there is no bearing seat at the connection end with the engine. When ...

Embodiment Construction

[0041] Combine below Figure 1 to Figure 6 Embodiments of the present invention are described in detail.

[0042] The large-scale generator load testing method is characterized in that a large-scale generator load testing device and a drive motor 200 are used to perform a load test on the test generator 100; the large-scale generator load testing device includes a bracket 1 for supporting the test generator The support assembly 2 and the shaft seat assembly 3 of 100, the shaft seat assembly 3 is horizontally arranged and fixed on the support 1, and the support assembly 2 is arranged in the support 1; the steps for performing a load test on the test generator 100 are:

[0043] In the first step, the test generator 100 is placed on the support assembly 2, and the rotor and stator of the test generator 100 are coaxially fixed with the shaft seat assembly 3;

[0044] In the second step, the test generator 100 is fixedly connected to the support 1;

[0045] The third step is to d...
