Abstract

The invention discloses a dual-OPGW-cable leading-down fastening device of a high-voltage transformer substation. The device comprises a left fastening mechanism, an adjustment and fastening hoop anda right fastening mechanism. Limiting devices are arranged at the adjustment and fastening hoop. An insulating support column is arranged at the left fastening mechanism; a threaded rod is fixed to the lower end of the insulating support column and penetrates the inside of a through tube; and the threaded rod and the through tube are limited and fixed by a fixed nut. A mounting plate is fixed to the upper end of the insulating support column by a fixed pin; a connecting insulating rod is fixed to the right side of the mounting plate; and a leading-down fasting clamp is fixed at the right sideof the connecting insulating rod. The right fastening mechanism has the same structure as the left fastening mechanism. According to the invention, with the fastening device, the construction cost ofthe project is lowered; the on-pole work time is reduced; the field assembling can be carried out conveniently; and the occupied rod area is reduced. Problems of cable shedding and connected pole discharging and strand breaking are solved. The fastening device can be used safely and reliability for long time; and the safe running rate of the OPGW terminal down cable of the ultra-high-voltage transformer substation is increased.

Description

technical field [0001] The invention relates to an OPGW double-cable down-guide fastening device, in particular to a high-voltage substation OPGW double-cable down-guide fastening device. Background technique [0002] A substation is a place in a power system that transforms voltage and current, receives electric energy and distributes electric energy. The substation in the power plant is a step-up substation, whose function is to boost the electric energy generated by the generator and feed it to the high-voltage grid. [0003] OPGW optical cable, Optical Fiber Composite Overhead Ground Wire (also known as optical fiber composite overhead ground wire). The optical fiber is placed in the ground wire of the overhead high-voltage transmission line to form an optical fiber communication network on the transmission line. This structure has dual functions of ground wire and communication, and is generally called OPGW optical cable. [0004] At present, two sets of independent f...
