Problems solved by technology

However, when the optical fiber is exposed to the air and affected by pollution, conductive dust, moisture, etc., high voltage will be generated along the surface of the optical fiber to flashover, and the introduction of high voltage into the low-voltage control and communication system will cause major equipment and personal accidents, which is quite dangerous.

Description

technical field [0001] The invention relates to an on-line temperature monitoring device for a high-voltage switchgear, in particular to a contact box structure directly connected to a photoelectric conversion optical fiber for on-line high-voltage temperature monitoring. Background technique [0002] At present, due to the manufacturing and installation deviations of the moving and static contacts in the removable switchgear, as well as the mechanical vibration caused by electrical wear, mechanical operation and short-circuit electric power during the operation process, the contact resistance increases, causing the temperature to rise and aggravate the contact resistance. Oxidation of the contact surface leads to excessive local temperature and major equipment accidents occur frequently. This phenomenon has become the weak link of switchgear, so how to accurately and conveniently monitor its real temperature online is a subject of concern to people in the industry. [0003...
