Utilize existing transmission line to be called power-line carrier communication as the method for medium transmission data, it starts from phase late 1950s, is the important means that carrier communication is carried out in electric power system.Coupling capacitor and filter joint are the important interface equipment that connects between high voltage transmission line and the carrier terminal equipment, the main at present split-type structural that adopts, and promptly coupling capacitor and filter joint are two independently parts, are connected with cable band iron copper strips therebetween.Though this split-type structural can be given carrier terminal equipment with high-frequency signal transmission from high voltage transmission line, but its shortcoming is because this two kinds of equipment bulky, therefore the consumption of the material and the energy is relative more, and it is big to take up room, wind resistance power is poor, and installation level and environment for use are bigger to its rate of failure and life-span influence; In addition, its body weight surpasses 35 kilograms, and it is big that required place not only is installed, and needs the fitting-up gang and the professional hanging device of specialty, backwoodsman construction difficulty particularly particularly in western part, even the situation of mounting cost much larger than the equipment purchasing expense appears; In addition, connection line length between two equipment and many, be that exposed contact is many in the air, so Installation and Debugging more complicated, especially because construction or natural rust etc. are former thereby contact loose contact meeting that cause makes its rate of failure high, and the thing that maintenance throughout the year allows power department feel a delicacy about especially, therefore this backward situation and power line communication modernization are extremely incompatible, thereby have seriously restricted the development process of electronic information.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide that a kind of volume is little, in light weight, compact conformation, Installation and Debugging and the very simple and cheap integrated coupling apparatus of power line carrier communication of maintenance.
In order to achieve the above object, the integrated coupling apparatus of power line carrier communication that provides of the utility model comprises the high-pressure side that is positioned at the insulator top and directly links to each other with high voltage transmission line; The high-voltage connection that the top terminal of high-pressure side and coupling capacitor is electrically connected; Be positioned at insulator top and directly be installed in coupling capacitor on the filter joint; The low-voltage lead of drawing and linking to each other from the bottom terminals of coupling capacitor with the low pressure exit; Be positioned at the filter joint that insulator bottom and its input and the lower curtate terminal of coupling capacitor directly link to each other; The high frequency cable exit of drawing from the filter joint output; The earth connection exit of drawing from the insulator base; And be connected the lightning arrester that shields between low pressure exit and the earth connection exit.
The integrated coupling apparatus of the power line carrier communication that the utility model provides is because its compact overall structure, so the raw material of the split-type structural of comparable prior art saving 40% and 25% energy consumption, and the exposed wiring point of equipment greatly reduces, can fundamentally solve multiple loose contact problem like this, thereby be convenient to Installation and Debugging and maintenance, and reduced relevant therewith expense; Particularly its weight has only about 9 kilograms, is particularly useful for being installed in the very difficult outlying mountain area of operation, thereby has tangible economic and social benefit.
