[0007] So although these above-mentioned patents all relate to utilizing ultraviolet light to monitor, and have proposed some specific monitoring methods, but all do not propose how to utilize ultraviolet light corona technology to carry out the method and the device of detection control to the insulating part of rail transit power supply system, and present Some rail transit power supply system insulation components generally work in relatively harsh working conditions, and are prone to deterioration of insulation performance. The insulation degradation of its components will directly lead to the reduction of safety factor and transportation efficiency, so further improvement is still needed

Embodiment 1
[0020] by attaching figure 1 It can be seen that the present invention relates to a method for detecting rail transit insulating parts using ultraviolet corona technology. According to the characteristics of high-voltage discharge, rail transit insulating parts will emit ultraviolet light before they are damaged during operation, and the rail transit insulating parts The emitted ultraviolet light is classified, and the ultraviolet sensor is used to detect the level of the discharge ultraviolet light emitted by the insulating parts of the rail transit to judge the insulation status of the insulating parts of the rail transit, so that the insulation performance of the insulating parts of the rail transit has not been completely destroyed Forecast the insulation status in advance to prevent damage to rail transit insulation components.

The present invention provides a method for detecting track traffic insulation parts through adoption of an ultraviolet corona technology. The track traffic insulation parts can emit ultraviolet light characteristics prior to being damaged during the running, the ultraviolet light emitted by the track traffic insulation parts is graded, and an ultraviolet sensor is adopted to detect the grade of the discharge ultraviolet light emitted by the track traffic insulation parts to determine the insulation condition of the track traffic insulation parts, so that the insulation condition may be forecasted before the insulation performances of the track traffic insulation parts are not completely damaged to prevent the track traffic insulation parts from being damaged. The method for detecting track traffic insulation parts through adoption of the ultraviolet corona technology is able to detect the insulation condition of the track traffic insulation parts through adoption of the ultraviolet corona technology to determine the insulation performances of the track traffic insulation parts, with non-contact detection, forecast the insulation condition in advance and effectively avoid over-heated faults.
Description
technical field [0001] The invention relates to a component detection method of rail transit, in particular to a method for detecting and controlling insulating components such as contact nets, insulators, and locomotive high-voltage equipment in rail transit equipment by using ultraviolet corona technology, which belongs to rail transit components Equipment monitoring and control technology field. Background technique [0002] As the source of power for electrified railway locomotives, the power supply system is very important and is an important part of rail transit. The power supply system is mainly composed of substations, catenary, insulators, locomotive high-voltage equipment, poles, etc. The power supply system is high-voltage and high-current. The insulation deterioration of its components directly leads to the reduction of safety factor and transportation efficiency. For example, electrified railways have been in operation for decades, and even high-speed railways ...
