Description

지중배전선로의 케이블 고정장치{Cable Fixing Device for Underground Distribution Lines}Cable fixing device for underground distribution lines {Cable Fixing Device for Underground Distribution Lines}

본 발명은 지중배전선로의 케이블 고정장치에 관한 것으로, 더욱 상세하게는 지반침하에 의해 전력구와 함께 처진 전력케이블을 원래의 높이로 상승시켜서 보정할 수 있도록 한 지중배전선로의 케이블 고정장치에 관한 것이다.The present invention relates to a cable fixing device for an underground distribution line, and more particularly, to a cable fixing device for an underground distribution line capable of correcting a power cable sagging along with a power outlet due to ground subsidence by raising it to its original height. .

화력발전소, 수력발전소, 원자력발전소 등의 발전소에서 약 20,000V 정도의 전압으로 발전된 전기는 송전에 적합한 초고압(154 KV 또는 345 KV)으로 승압되며 승압된 전기는 초고압선로를 통하여 1차 변전소로 송전된다.Electricity generated at a voltage of about 20,000V at power plants such as thermal power plants, hydroelectric power plants, and nuclear power plants is boosted to extra-high voltage (154 KV or 345 KV) suitable for transmission, and the boosted electricity is transmitted to the primary substation through extra-high voltage lines. .

1차 변전소는 배전된 초고압의 전기를 특고압인 22.9 KV로 강하시켜 대용량의 수용가 근처에 위치한 2차 변전소 또는 배전선로를 따라 일반수용가로 송전 또는 배전한다.The primary substation drops the distributed extra-high voltage electricity to 22.9 KV, which is a special high voltage, and transmits or distributes power to general consumers along the secondary substation or distribution lines located near large-capacity consumers.

1차 변전소 또는 2차 변전소로부터 배전된 전기는 가공배전선과 지중배전선으로 구성된 송배전선로를 통해 각 수용가의 수전설비로 송전 또는 배전되며 특고압수용가, 고압수용가 및 각종 옥외설치 변압기를 통하여 저압수용가에까지 송배전되어 산업용, 가정용 등으로 사용된다.The electricity distributed from the primary substation or secondary substation is transmitted or distributed to the receiving facilities of each customer through transmission and distribution lines composed of overhead distribution lines and underground distribution lines, and is transmitted and distributed to low-voltage customers through extra-high voltage customers, high-voltage customers, and various outdoor transformers. It is used for industrial and household purposes.

한편, 전력구를 이용한 지중배전선로는 지반침하에 의해 일부의 전력구가 하강되면 포설된 전력케이블에 처짐이 발생하면서 전력케이블에 과도한 장력이 가해지는데, 이를 방치하면 전력케이블의 수명이 크게 저하되는 문제점이 있었다.On the other hand, in the underground distribution line using power tunnels, when some power outlets are lowered due to ground subsidence, sagging occurs on the installed power cables, and excessive tension is applied to the power cables. There was a problem.

이러한 문제를 개선하기 위해 국내 등록특허 제10-2292482호의 종래기술이 개시된 바 있으며, 이러한 종래기술은 랙과 피니언을 이용해서 분할된 벽체를 상승시킨 다음 스프링에 의해 전진 방향으로 힘을 받는 로드를 고정판에 형성된 구멍에 걸리도록 해서 상승된 위치를 지속적으로 유지하도록 구성된 것이다.In order to improve this problem, the prior art of Korean Registered Patent No. 10-2292482 has been disclosed, and this prior art raises the divided wall using a rack and pinion, and then moves a rod that receives force in the forward direction by a spring to a fixed plate. It is configured to continuously maintain an elevated position by being caught in a hole formed in.

그러나, 이와 같은 종래기술은 고정판에 형성된 구멍이 한 개만 형성되어 있기 때문에 높이를 임의로 설정해서 고정할 수 없는 치명적인 단점을 갖고 있었다.However, this prior art has a fatal disadvantage in that the height cannot be arbitrarily set and fixed because only one hole is formed in the fixing plate.

국내 등록특허 제10-1145356호(공고일 2012.05.17.)Domestic Patent Registration No. 10-1145356 (Announcement date 2012.05.17.) 국내 등록특허 제10-2292482호(공고일 2021.08.24.)Domestic Patent Registration No. 10-2292482 (Announcement date 2021.08.24.)

본 발명은 상기와 같은 문제점을 해결하기 위하여 이루어진 것으로, 그 목적은 지반침하에 의해 처짐이 발생한 전력케이블을 원래의 위치로 상승시켜서 보정할 수 있는 지중배전선로의 케이블 고정장치를 제공함에 있다.The present invention has been made to solve the above problems, and its object is to provide a cable fixing device for an underground distribution line capable of correcting a power cable sagging caused by ground subsidence by raising it to its original position.
