Description

technical field

[0001] The invention belongs to the technical field of WiFi wireless remote control DC high-voltage power supply. Specifically relates to a WiFi wireless remote control DC high-voltage power supply for cable fault detection equipment. Background technique

[0002] With the rapid development of my country's economy, power cables play an increasingly important role in the planning and construction of urban power grids, and gradually replace the laying of overhead open wire cables to become the dominant direction of future power grid development. However, because the cables are buried deep underground, once a fault occurs, it will be difficult to quickly detect and locate the fault manually. Therefore, a cable fault detection system is needed to realize the identification, detection and location of the fault point of the deeply buried cable. The cable fault detection system uses a high-voltage power supply as a high-voltage signal generator to provide a certain...
