Abstract

The invention provides a linear interconnection method and device for an optical fiber composite power cable. The interconnection device comprises two strain preformed silk hardware tools (1) which are respectively arranged on two ends (to be interconnected) of the optical fiber composite power cable (5), a tensioning member (2) and an intermediate connection box (3), wherein two ends of the tensioning member (2) are respectively connected with the two strain preformed silk hardware tools (1) at the opposite sides, and the tensioning member (2) is used for tensioning and fixing the optical fiber composite power cable (5); and the intermediate connection box (3) is provided with two cable inlets (35) which are used for respectively introducing optical fiber wires (to be interconnected) of the optical fiber composite power cable (5). The interconnection device can realize the interconnection of an optical fiber composition phase conductor (OPPC) or an optical fiber composite overhead ground wire (OPGW) at a linear gear and has performances of tension interconnection, communication optical fiber interconnection and electric power wire interconnection; and in addition, all the performances of the interconnection device can meet requirements of a normally high-voltage power transmission line operation standard.

Description

technical field [0001] The invention relates to a power system, in particular to a method and a device for straight-line splicing of an optical fiber composite power cable. Background technique [0002] Optical fiber composite phase line (OPPC) and optical fiber composite overhead ground wire (OPGW) are characterized by communication optical fibers inside, which can not only transmit current, but also communicate. However, due to this feature, it cannot be squeezed, and the conventional crimping process cannot be used for straight-line splicing, and at the same time optical fiber splicing is required, so the shortcomings in use must be carried out on the strain tower of the high-voltage transmission line. However, the number of tension towers of normal transmission lines is small, and each tension section is relatively long. Once the wires in this section have problems such as disconnection, etc., the optical fiber composite phase conductor (OPPC) of the entire tension secti...

However, due to this feature, it cannot be squeezed, and the conventional crimping process cannot be used for straight-line splicing, and at the same time optical fiber splicing is required, so the shortcomings in use must be carried out on the strain tower of the high-voltage transmission line. However, the number of tension towers of normal transmission lines is small, and each tension section is relatively long. Once the wires in this section have problems such as disconnection, etc., the optical fiber composite phase conductor (OPPC) of the entire tension section must be replaced. , which will waste a lot of capital and labor, and also bring great difficulties to design, infrastructure construction and manufacturing
