Transformer substation OPGW terminal reserved cable and manufacturing method thereof

Abstract

The invention discloses a transformer substation OPGW terminal reserved cable and a manufacturing method thereof. An insulating protection layer is arranged on the tail end of the OPGW terminal reserved cable, and an OPGW optical cable with the insulating protection layer is formed. The insulating protection layer comprises a waterproof object and an insulating protection sleeve. The waterproof object is a coated waterproof gluing object or a wound insulating tape. The insulating protection sleeve sleeves the waterproof object. Pyrocondensation processing is carried out on the insulating protection sleeve through a pyrocondensation processing device, so that air in the insulating protection sleeve is eliminated. The tail end of the OPGW optical cable with the insulating protection layer is connected into an OPGW optical cable connection box. The invention further provides a manufacturing method of the transformer substation OPGW terminal reserved cable.

Description

technical field [0001] The invention relates to the technical field of electric power systems, in particular to a substation OPGW terminal reserved cable and a manufacturing method thereof, which are mainly used in ultra-high voltage, ultra-high voltage, and high-voltage substations of electric power systems. Background technique [0002] With the continuous development of society, electric power has become an indispensable energy source for people's production and life, so the technical development of substations closely related to electric power has attracted more and more attention. [0003] At present, the outer structure of OPGW (Optical Fiber Composite Overhead Ground Wire, optical fiber composite overhead ground wire) optical cable in ultra-high voltage, ultra-high voltage, and high-voltage substations in domestic and foreign power systems is aluminum-clad steel bare stranded wire. Since the OPGW optical cable is erected on the same pole on the upper part of the trans...

AI Technical Summary

Problems solved by technology

Since the OPGW optical cable is erected on the same pole on the upper part of the transmission line tower, the transmission line will generate induction electricity to the OPGW optical cable. When the OPGW optical cable enters the substation, it will generally be introduced into the reserved cable fork and wound 4-10 times. OPGW optical cable has inter-turn contact, and OPGW optical cable induces electricity to cause inter-turn contact discharge and electric erosion to break the strands.

If there is a risk of broken strands in the OPGW optical cable in operation, it will cause major equipment hidden dangers to the backbone communication optical cable lines of the power grid, directly threatening the safe production of the current smart grid
