Description

technical field [0001] The invention relates to the technical field of high-voltage substation system protection, in particular to an intelligent overvoltage protection and detection and alarm device. Background technique [0002] In the high voltage substation system, damp and explosion of resistors are the most likely faults in the operation of zinc oxide arresters, accounting for about 90% of arrester faults. How to quickly and easily judge the fault conditions of such arresters and make timely Response has always been a difficult problem faced by the staff of high voltage power distribution system. [0003] Patent No. CN201020137355.2 relates to a wireless online monitoring device for lightning arresters, including a host computer, multiple wireless sensor base stations, multiple wireless leakage current monitoring sensors and multiple wireless voltage monitoring sensors. Long-distance wireless two-way data transmission is adopted between the above-mentioned multiple wi...
