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.
