Embodiment Construction

[0027] refer to figure 1 , the generator air-gap waveform acquisition method in one embodiment can be applied to the control terminal, including cyclic execution of the following steps S110, S130, S150 and S170.

[0028] S110: Obtain the operating parameters during the start-up and stop of the generator.

[0029] When the generator is overhauled, it is necessary to start and then stop the generator; during the start-up process, the power of the generator gradually increases from zero to realize the start-up of the generator, and during the shutdown process, the power of the generator gradually decreases to zero. Generator shut down. The start-up and shutdown process includes the start-up process and the shutdown process of the generator, that is, the operating parameters obtained in step S110 include the operating parameters of the start-up process and the shutdown process during the generator overhaul process.

[0030] S130: When the operating parameters match the preset st...

Abstract

The invention relates to a generator air gap waveform acquisition method, a device and an acquisition system; the method comprises the following steps: obtaining operation parameters in a generator start up and shut down process, and start gathering the generator air gap waveforms if the operation parameters are matched with preset standard parameters; recording a waveform acquisition duration, and stop gathering when the waveform acquisition duration equals to the preset duration, thus obtaining the air gap waveforms gathered in the waveform acquisition duration. The method can automaticallygather the air gap waveforms in the generator normal start up and shut down process, and manual operation is not needed to adjust and fix the generator operation parameters, thus making no extra timestay in the generator normal start up and shut down process, and saving repairing time.

Description

technical field [0001] The invention relates to the technical field of waveform acquisition, in particular to a generator air gap waveform acquisition method, device and system. Background technique [0002] The maintenance of generators generally includes three items: overhaul, medium repair and minor repair. To overhaul the generator, it is necessary to adjust the power of the generator at a constant speed to control the start and stop of the generator. During the start and stop process, it is usually necessary to collect the air gap waveform under specific operating parameters, and compare the collected air gap waveform with the standard Compare the air gap waveforms to analyze the inter-turn insulation of the rotor, such as collecting the air gap waveforms at specific powers during the start and stop of the generator. [0003] The traditional method of collecting the air gap waveform of the engine is generally determined by the staff to keep the operating parameters of ...
