High-voltage switch contact temperature detection and control system

Abstract

The invention relates to the field of power supply equipment detection and discloses a high-voltage switch contact temperature detection and control system. The high-voltage switch contact temperaturedetection and control system comprises a cooling mechanism, a control module, an infrared thermal imager and an image processing module. The infrared thermal imager is spaced from contacts (4) of a high-voltage switch and directed towards the contacts (4) of the high-voltage switch to convert the sensed temperature into image data. The image processing module is connected to the infrared thermalimager to convert the image data into a temperature value and output the temperature value to the control module. The control module is connected to the cooling mechanism to control the cooling mechanism to perform cooling when the temperature value is greater than a preset temperature. The high-voltage switch contact temperature detection and control system overcomes the problems of high heatingtemperature and high difficulty in installing a temperature sensor for accurate detection in the prior art, and solves the problem of difficulty in accurate detection of high-voltage switch contact temperature by the infrared non-contact temperature measurement technology.

Description

technical field [0001] The invention relates to the field of power supply equipment detection, in particular to a high-voltage switch contact temperature detection and control system. Background technique [0002] The reliability of power supply is directly related to the safety of rail transit system operation. If the power supply equipment fails, it will often cause the rail transit to be out of service, and even cause safety accidents, which will not only cause huge economic losses, but also endanger the personal safety of passengers. cause extremely bad social impact. The rail transit lines are long, there are many power supply equipment, and there are many inspection points. The traditional inspection method with special personnel on duty is difficult to meet the maintenance needs of equipment. The use of data acquisition and monitoring control to monitor and control power supply equipment has been widely used and has become a development trend. In recent years, with ...
