Abstract

The invention relates to the technical field of travel survey, in particular to a high-voltage motor insulation detection method and device. The method comprises the following steps: a first experiment for detecting the surface conductivity fouling of the high-voltage motor coil; and / or a second experiment for detecting the aging degree and dielectric loss of the insulating layer of the high-voltage motor coil; and / or a third experiment for detecting the partial discharge amount in the insulating layer of the high-voltage motor coil. All data are collected within the rated voltage range of thehigh-voltage motor, and the experiment is reliable and stable; no harm is caused to client equipment; the operation is convenient and easy; and the experiment time is short, and the whole experimentprocess is within one hour.

Description

technical field [0001] The invention relates to the technical field of travel investigation, in particular to a method and device for detecting insulation of a high-voltage motor. Background technique [0002] High-voltage motor insulation diagnosis is to judge the conductive contamination of the coil surface, surface partial discharge, local damage, insulation internal air gap state, and insulation internal partial discharge through experimental data. The corresponding plan is adopted for the use and maintenance of the equipment, so that customers can understand the status of the equipment, and take timely measures to reduce risks and save costs. The existing high-voltage motor insulation diagnosis technology is immature, and it is often necessary to send the equipment to be diagnosed to the laboratory for a withstand voltage test, which has great harm to the equipment and reduces the service life of the equipment. At the same time, the existing withstand voltage test metho...
