Compared with the traditional heat-sensitive detection method without anti-mistake protection function, the present application has great advantages.

Description

technical field [0001] The invention belongs to the field of anti-misoperation protection of electric high-voltage equipment, and in particular relates to a heat-sensitive anti-misoperation protection device of an array of electric high-voltage equipment. Background technique [0002] There are three methods for the existing overheating protection technical solutions of traditional electric high-voltage equipment: 1) Power off the high-voltage equipment, and do corresponding electrical tests such as contact resistance, withstand voltage, leakage, insulation, etc.; 2) The staff carry infrared thermal imaging The instrument performs manual temperature measurement and scanning on the electric high-voltage equipment one by one; 3) The newly developed infrared robot detection. Among these three technical schemes, the first one needs to be powered off, and online detection and protection cannot be performed. The second type requires manual operation. When an overheating fault occ...

[0004] The purpose of the present invention is to provide an array thermosensitive anti-malfunction protection device for electric high-voltage equipment and its protection method. According to the intervals of different types of electric high-voltage equipment, corresponding lattice arrays are set up, and two sets of parallel array infrared thermal probes are respectively installed on the The interval between electric high-voltage equipment is conducive to effective monitoring and detection at the appropriate position. Through the pre-designed programming of the control module, the thermal-sensitive anti-misoperation protection function of electric high-voltage equipment is realized. This is a new secondary anti-mistake protection function for power high-voltage equipment The protection method solves the problem that the traditional thermal detection of high-voltage electric power equipment cannot perform anti-mistake protection for overheating faults. Compared with the traditional thermal detection method without the function of anti-mistake protection, this application has a huge advantage
