Description
Technical Field
The utility model relates to a diameter-variable universal steel belt hoop assembly, in particular to a universal steel belt hoop assembly for fixing an OPGW (optical fiber composite overhead ground wire) cable down-leading insulator.
Background
In a national power grid, a fault of strand breaking caused by discharging of an entrance OPGW optical cable to a portal frame of a transformer substation is discovered in the transformer substation with different voltage levels for many times, and the communication safety and normal operation of each level of power grid system are seriously threatened.
The down-leading optical cable and the in-station framework are fixed by adopting a matched fixing clamp and insulating rubber, and the distance between the down-leading optical cable and a tower framework piece is not less than 20 mm. "is a measure generally adopted by a transformer substation under the current power regulation.
In the fixing mode, one insulating rubber clamp is easy to age, so that the OPGW led-down optical cable is loosened, and the distance between the loosened OPGW led-down optical cable and the framework tower is short. And secondly, the distance between the OPGW and the optical cable is not less than 20mm, and under the reasons of lightning, short circuit, operation and the like, the induced voltage on the optical cable drawn by the OPGW can break down the distance and form a discharge arc to burn the OPGW optical cable. Secondly, the stainless steel band width of the fixed insulating rubber clamp is not more than 20mm, the thickness is not more than 1.2mm, and the strength of the steel band is particularly weak under the influence of wind resistance swing in a high-voltage-class transformer substation. Although the ability of the steel strip to adapt to different rod diameters of the pull-down framework of the OPGW optical cable is not doubtful, on the premise of ensuring the communication safety and normal operation of the OPGW optical cable, the fixed clamp formed by the thin steel strip still has certain hidden danger to the whole system in view of the analysis.
The pole diameter of a framework of the transformer substation is inconvenient to measure on site, particularly the pole diameter of the upper part of the framework, even if the measured conical pole diameter possibly has a certain error with the actual pole diameter, inconvenience is brought to field installation, and even installation and construction cannot be completed. Meanwhile, the on-site measurement increases the cost and delays the supply period to a certain extent.
