Description
본 발명은 특고압전선용 무정전 절연커버구조에 관한 것으로서, 보다 상세하게는 간편한 조립방식으로 이루어져 무정전 절연커버의 취부작업이 표준화되고, 빗물의 유입을 방지하여 감전이나 누전에 의한 안전사고의 발생이 줄어들며, 도시미관을 해치지 않게 되는 특고압전선용 무정전 절연커버구조에 관한 것이다. The present invention relates to an uninterruptible insulation cover structure for high-voltage wires, and more specifically, the assembly of the uninterruptible insulation cover is standardized by a simple assembly method, and the occurrence of safety accidents due to electric shock or leakage is reduced by preventing rainwater from entering. In addition, the present invention relates to an uninterruptible insulation cover structure for an extra high voltage wire that does not harm the aesthetics of a city.
일반적으로 일관작업을 하는 공장 등에서는 정전이 되면 생산라인에 많은 문제를 가져오게 되므로, 전기공사를 할 경우에는 정전시키지 않고 공사하는 무정전 작업을 많이 하게 된다.In general, when a power failure occurs in a factory that performs consistent work, a lot of problems occur in a production line. Therefore, when electrical work is performed, a lot of uninterrupted work is performed without power failure.
이렇게 무정전 작업을 할 경우에는 특고압전선의 일부에 피복을 제거하고, 이 피복이 제거된 부위에는 클램프로 바이패스 케이블 헤드를 연결하여 작업하게 된다.In the case of uninterrupted work, the cover is removed from a part of the extra high voltage wire, and the bypass cable head is connected to the part where the cover is removed by a clamp.
그리고, 무정전 작업을 끝낸 후에는 피복을 제거한 부위에는 분기슬리브 커버를 취부하여 특고압전선의 피복제거부를 절연하게 된다.After the uninterruptible work is completed, a branch sleeve cover is attached to a portion where the coating is removed to insulate the coating removing portion of the high-voltage cable.
상기 분기슬리브 커버를 취부한 상태의 특고압전선은 데드 앤드 클램프를 매 개로 현수애자에 연결되어 있다. 상기 현수애자는 전주의 완금에 설치되어 있다. 상기 데드 앤드 클램프에는 데드 앤드 커버가 씌워져 있다. 상기 특고압전선의 중간부에서 피복을 제거한 부위에는 분기슬리브 커버가 취부되어 있다.The extra high voltage wire with the branch sleeve cover attached is connected to the suspension insulator with a dead end clamp. The suspension insulator is installed at the completion of Jeonju. The dead end cover is covered with a dead end cover. A branch sleeve cover is attached to a portion where the cover is removed from the middle portion of the extra high voltage wire.
그러나, 종래에는 무정전 작업시 특고압전선의 임의의 장소에 피복을 제거한 후 분기슬리브 커버를 취부하고 있으므로, 무정전 작업의 증가로 인하여 특고압전선의 피복제거에 따른 분기슬리브 커버의 취부개소가 증가하게 되어, 도시미관을 해친다는 문제점이 있었다.However, in the prior art, since the branch sleeve cover is mounted after removing the cover at any place of the extra-high voltage cable during the uninterruptible work, the branch sleeve cover is increased due to the increase in the uninterruptible work. There was a problem that it hurts the city view.
또한, 작업방법이 표준화되어 있지 않으므로, 임의의 개소에서 피복을 제거하여 무정전 작업 및 분기슬리브 커버의 취부작업을 하게 되면 안전사고가 발생하게 된다는 문제점이 있었다.In addition, since the work method is not standardized, there is a problem that a safety accident occurs when the uninterruptible work and the attachment of the branch sleeve cover are removed by removing the cover at any point.
