Embodiment Construction
[0054] In order to better understand the present invention, the content of the present invention will be further described below in conjunction with the accompanying drawings and examples.
[0055] The invention provides an ice-melting optical fiber composite overhead ground wire joint box and a connection method of the joint box. The joint box is used to connect the ice-melting optical fiber composite overhead ground wire. The structure of the ice-melting optical fiber composite overhead ground wire is as follows figure 1 As shown, it includes a central reinforcing wire, an outer monofilament 1, an ice-melting wire 2 and an optical fiber unit 3. One or more ice-melting conductors 2 and optical fiber units 3 are twisted between the central strengthening wire and the outer monofilament, which constitutes the ice-melting optical fiber composite overhead ground wire, and the central strengthening wire and the outer monofilament are used to improve Mechanical strength of ice-melti...

The invention provides a conjunction box of ice-melting composite fiber-optic overhead ground wires and a connection method of the conjunction box. The conjunction box comprises a fiber junction cavity and an ice melting power supply connection cavity separated from the fiber junction cavity by an insulated separating layer; the fiber junction cavity is provided with a fiber splice tray and a porcelain conductor connecting insulator, and the bottom of the fiber junction cavity is provided with a cable guiding-in hole whose inner wall is conical; and the ice melting power supply connection cavity is internally provided with a plugging type connection seat which is connected with the porcelain conductor connecting insulator via a lead. According to technical schemes of the invention, the problem that a common composite fiber-optic overhead ground wire connection method cannot be used to melt ice after icing is solved, the problems that during ice-melting power supply connection, operation is difficult, time and labor are consumed and a line needs to be power off for construction are also solved, time of first-aid repair is saved, and it is ensured that fiber communication is not influenced during ice melting.
Description
technical field [0001] The invention relates to a splice box and a connection method of the splice box, in particular to an ice-melting optical fiber composite overhead ground wire splice box and a connection method thereof. Background technique [0002] After entering the new century, the frequency of icing accidents on transmission lines is increasing, and the losses caused by icing disasters on overhead transmission lines are becoming more and more serious, resulting in large-scale power and communication terminals, which have seriously affected people's lives and work. . [0003] There have been related reports on the research on the control of icing disasters on transmission lines, which disclosed some feasible icing technologies for transmission lines and applied them to actual lines. The ice-melting optical fiber composite overhead ground wire is an ice-melting conductor twisted inside the ordinary optical fiber composite overhead ground wire (OPGW). Icing outside o...
