Abstract

The invention relates to an inductance coupling device for broadband communication by using a middle-pressure overhead power transmission line. In the invention, an overhead line coupling device and an inductance coupler are arranged on the middle-pressure overhead power transmission line; the overhead line coupling device is a signal exchange device which consists of a high-pressure coil, a high-pressure signal connector, a low-pressure coil and a low-pressure signal connector and can realize signal exchange between high-pressure and low-pressure ends; and the inductance coupler is a magnetic medium component which consists of a main body left semicircle, a main body right semicircle, a hoop, a buckle and a limiting projection and can couple signals transmitted by the overhead line coupling device and the middle-pressure overhead power line. The inductance coupling device has the advantages of coupling the signals transmitted by the overhead line coupling device and the middle-pressure overhead power line, accessing signals of middle-pressure power line broadband network communication equipment, avoiding the magnetic saturation of the inductance coupler when a loading current on the power line is too large, working without power cut, along with simple structure, high cost performance, high insulation strength, high-temperature resistance of the inductance coupler, high band width, low inductive impedance, low signal transmission attenuation, high signal coupling performance, convenient installation and maintenance and the like and is suitable to be used in electric communication departments.

Description

1. Technical field [0001] The invention relates to the field of electric power communication engineering, in particular to an inductive coupling device for medium-voltage overhead power line broadband communication, which is especially suitable for application in electric power communication departments. 2. Background technology [0002] Power line carrier communication uses the power line for signal transmission, that is, the high-frequency signal carrying information is modulated and loaded on the current, and transmitted through the power line, and the receiving end separates the useful signal from the current through coupling, demodulation, etc. For end users, this communication method has the advantages of easy deployment and no wiring, and has been a hot area of ​​communication technology research since its birth. With the development of science and technology, the modulation technology of power line communication has developed from the original traditional analog modu...
