Embodiment Construction
[0018] Below in conjunction with accompanying drawing, narrate an embodiment, the present invention is described further.
[0019] figure 1 The overall structure of the system of this embodiment is shown.
[0020] An equipment safety monitor 4 is installed on the output side of the 10KV transformer, and an equipment safety monitor 8, an intelligent power measurement and control instrument 7, and a multi The functional electric energy meter 9 implements hierarchical leakage detection and hierarchical management, and uploads the detection data directly to the main station 1 or through the sub-station 2 to the main station 1. The main station 1 monitors and analyzes the data, and implements it through the medium and low voltage remote meter reading system. power off.
[0021] The equipment safety tester 4 is installed on the output side of the 10KV transformer of each substation to monitor the leakage current; the equipment safety tester 8 is installed on the output side of the...
