Description

도시지역 지중배전선로의 안정화 시스템{Fixing System for underground power distribution line} Stabilization system for underground power distribution lines in urban areas {Fixing System for underground power distribution line}

본 발명은 배전 기술 분야 중 도시지역 지중배전선로의 안정화 시스템에 관한 것으로서, 더욱 상세하게는 지중배전기 내부의 부싱과 결합되는 배전선로 일단의 커넥터를 견고히 지지하기 위한 구조를 갖는 도시지역 지중배전선로의 안정화 시스템에 관한 것이다. The present invention relates to a system for stabilizing an underground distribution line in an urban area in the field of distribution technology, and more particularly, to an underground distribution line in an urban area having a structure for firmly supporting a connector at one end of a distribution line coupled with a bushing inside an underground distribution line. It relates to a stabilization system.

일반적으로 지상으로 배전선로를 노출시키지 않도록 이를 지중에 매설하는 방식이 많이 채택되고 있는데, 매설된 배전선로의 중간에는 부하개폐기를 구비한 지중배전기를 설치하여 수용가까지 안정적으로 전력이 공급되도록 하고 있다.In general, a method of burying the distribution line in the ground so as not to expose the distribution line to the ground is widely adopted.In the middle of the buried distribution line, an underground distributor equipped with a load switch is installed so that power is stably supplied to the customer.

수용가까지 전력을 공급하기 위해서 지중배전기 내 부하개폐기에 설치되어 외측으로 돌출되는 부싱에는 배전선로가 연결되는데, 이 부싱과 배전선로의 연결은 별도의 커넥터에 의해 이루어진다. In order to supply electric power to the customer, a distribution line is connected to a bushing installed at the load switch in the underground distribution and protruding outward, and the bushing and the distribution line are connected by a separate connector.

그런데 이러한 커넥터가 단순히 부싱에 끼움 결합되는 경우 진동이나 자중에 의해 그 부싱으로부터 분리될 수 있어, 이에 대한 보수작업이 요구될 시에 매우 번거로운 문제점이 있다.However, when such a connector is simply fitted into the bushing, it may be separated from the bushing by vibration or its own weight, and thus there is a very cumbersome problem when a maintenance work is required.

상기의 문제점을 해결하기 위한 등록특허 제10-0721717호에서는 커넥터 배면에 오목홈을 형성하고 그 오목홈에 삽입되는 돌기가 형성된 가압블록이 설치된 고정암으로 커넥터를 가압하는 구조를 갖고 있다. Registered Patent No. 10-0721717 for solving the above problems has a structure in which a concave groove is formed on the rear surface of the connector, and the connector is pressed with a fixing arm provided with a pressing block having a projection inserted into the concave groove.

이와 같은 구조에 따르면 커넥터 또한 가압블록의 크기를 고려하여 특정 형상으로 제작되어야 하는 한편으로 그 구조 또한 복잡하여 제작과 유지보수에 따른 비용이 많이 소모되는 문제점이 있다. According to such a structure, the connector must also be manufactured in a specific shape in consideration of the size of the pressing block, while the structure is also complex, and thus, there is a problem that a lot of costs are consumed for manufacturing and maintenance.
