Problems solved by technology
Since both wireless temperature measurement and infrared temperature measurement technologies use electronic sensors as on-site sensing units, the on-site sensors are charged and are easily affected by strong magnetic fields and high voltages, and are prone to aging after long-term work, bringing safety hazards to equipment
Optical fiber temperature measurement technology can avoid the above problems, but the current optical fiber temperature measurement mainly uses optical cables, which cannot measure the temperature of specific contacts and can only be used for long-distance temperature measurement
Therefore, it is not suitable for short-distance and temperature measurement of specific contacts such as high-voltage switchgear

Description
technical field [0001] The present invention relates to the technical field of optical fiber sensing, in particular to an optical fiber temperature measuring host used for a high-voltage switchgear, a system including the optical fiber temperature measuring host, and a temperature measurement method using the optical fiber temperature measuring host. Background technique [0002] Various contacts, busbars, cable joints and connectors of electrical equipment inside the high-voltage switchgear are prone to poor contact and abnormal plug-in eccentricity. This will cause the contact resistance to be too large, and the heat will be serious under high current. Failure, destroying the safety and reliability of power supply, this is the main failure form of high-voltage switchgear. Therefore, real-time temperature monitoring of the contact head, timely detection of hot spots in the switch cabinet, and early prediction and alarm of faults are extremely important for ensuring the saf...
