A device and method for installing reserved cables for OPGW terminals in substations

Abstract

This application discloses an installation device for reserved cables for OPGW terminals in substations, which completely solves the inter-turn contact discharge and electric erosion caused by the OPGW inter-turn induction electricity wound in the OPGW terminal reserved disks of ultra-high voltage, ultra-high voltage, and high-voltage substations. It improves the safe operation rate of cables reserved for OPGW optical cable terminals in UHV, EHV, and HV substations, eliminates the hidden dangers of optical cable backbone line equipment in the power grid, promotes the safe operation rate of the power grid, and reduces the lack of maintenance work for optical cables. The operation and maintenance cost of power grid enterprises is reduced, and the on-site construction is convenient, simple and easy to implement. It includes waterproof glue, insulating protective sleeve, and heat shrink treatment equipment. Apply waterproof glue or wind insulating tape at the end of the OPGW terminal reserved cable, put the insulating protective sleeve into the part coated with waterproof glue, and pass The heat-shrinking treatment equipment performs heat-shrinking treatment on the insulating protective cover, thereby eliminating the air in the insulating protective cover. Methods are also provided.

Description

Technical field [0001] The present invention relates to the technical field of power systems, and more particularly to a mounting apparatus of a substation OPGW terminal reserved cable and a method thereof, mainly used in the high pressure, ultra high pressure and high pressure substation of the power system. Background technique [0002] With the continuous development of society, electricity has become an indispensable energy for people, and therefore the technology development of substation related to electricity is increasingly attracted more and more. [0003] At present, the outer structure of the OPGW (Optical Fibercomposite Overhead Ground Wire, Optical FiberComposite Overhead Ground Wire, Optical Composite Overhead) of the Power System at home and abroad is the outer structure of the optical cable. Since the OPGW optical cable is hierarchical in the upper portion of the tower of the transmission line, the power transmission line will generate an induction electricity for...

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 optical cable lines of the power grid, directly threatening the safe production of the current smart grid
