Description

technical field [0001] The invention relates to the collection and processing of temperature signals, in particular to a contact-type high-voltage electrical temperature detection system. Background technique [0002] In modern industry, abnormal operation or failure of industrial equipment usually shows abnormal temperature changes. For example, high-voltage switchgears in power plants and substations are important electrical equipment. During the long-term operation of the equipment, the joints of the dynamic and static contacts in the switchgear and the joints of the busbars and other parts of the switchgear are heated due to excessive contact resistance due to factors such as oxidation and looseness, forming a vicious circle, and these heat-generating parts become failures. The hidden dangers of accidents, once electrical equipment safety problems occur, will cause huge economic losses. In other important areas, temperature detection plays a vital role in equipment and ...
