Description

technical field [0001] The invention relates to the technical field of long-distance power supply, in particular to a long-distance power supply generator and a method for locating long-distance power supply faults. Background technique [0002] Various monitoring equipment on expressways generally adopt centralized or relatively centralized power supply. The power used is drawn from the power plant or the high-voltage power grid in the nearby area, and sent to the substation of the expressway itself. The 220V or 380V alternating current is generated through the low-voltage transformer, and then passed through the power cable. Provide power to remote monitoring equipment. [0003] The power supply mode in expressway mechanical and electrical engineering is strip-shaped, the power supply distance is long, and the load is relatively small and scattered. The substations are generally set in the management center, toll station, service area or maintenance work area, and the pow...
