Embodiment Construction
[0014] figure 1 Schematic diagram of the use of the embodiment of the present invention. The present embodiment includes the receiving unit 100 at the power room or station substation, the calibration unit 200 on the power line, the receiving unit 100 includes a feed receiver 105, a zero-crossing detection circuit 107, a carrier receiving unit 104, and a data processing unit 101 , alarm prompt unit 102, backup power supply 103, calibration unit 200 includes electromagnetic inductor 201, rectifier circuit 202, battery 203, code generator 204, code transmitter 205, coupling circuit 206, zero-crossing detection circuit 207; In this implementation In the example, the electromagnetic inductor 201 is a magnetic core voltage sensor that can be opened. When in use, the ferromagnetic core is stuck on the high voltage line, and the coil wound on the magnetic core is used as a secondary. When the high voltage line in the magnetic core passes through the current, the ferromagnetic core A...
