345㎸ 2도체용 폴리머 상간스페이서{Bundle type phase to phase polymer spacer for 345㎸ power transmission line}Bundle type phase to phase polymer spacer for 345㎸ power transmission line

본 발명은 복도체 송전선로의 상간에 설치하여 이 상간 이격거리의 부족개소 내지는 빙설해, 갤로핑(Galloping) 및, 전선도약(Sleet Jump) 등에 의한 송전선로의 상간 단락고장을 방지하는 폴리머 상간스페이서(Polymer Phase Spacer)에 관한 것으로, 특히 상간스페이서의 절연설계와 설치 편의를 위해 상간스페이서 길이조절 및 절연전압 상승으로 발생할 수 있는 코로나 방지구조를 갖춘 345㎸ 2도체용 폴리머 상간스페이서에 관한 것이다.The present invention is installed between the phases of the corridor transmission line, the polymer phase spacer to prevent the short-circuit failure of the transmission line by the galloping and the slip jump, such as the lack of the distance between the phases or ice. The present invention relates to a polymer phase spacer for a 345 ㎸ two-conductor having a corona-preventing structure that can be caused by phase length adjustment and insulation voltage rise for the insulation design and installation convenience of the phase spacer.

전력 송전에 있어서 송전선로의 전력선과 전력선 사이의 상간 이격거리를 일정하게 유지시키는 상간스페이서는 송전선로의 상간에 설치하여 빙설해 등 기상현상에 의한 송전선로의 상간 혼촉 고장을 예방하고, 이 송전선로의 고장발생에 따른 산업의 피해예방과, 고도제한 등으로 송전선로의 상간 이격거리 축소가 필요한 개소 등에 널리 활용되고 있다.An interphase spacer that maintains a constant distance between phases of power lines and power lines in power transmission lines is installed between phases of transmission lines to prevent interphase failure of transmission lines due to meteorological phenomena such as ice and snow. It is widely used in places that need to reduce the distance between phases of transmission lines due to industrial damage prevention and altitude restrictions.

종래 일반적인 폴리머 상간스페이서는 단/복도체 고정형 및 약 50㎝ 단위의 단/복도체 가변형 절연로드 2-5단으로 되어 있는데, 이중 도 5는 종래 복도체 고정 형 폴리머 상간스페이서를 도시한 것이다.Conventional conventional polymer phase spacers are composed of a single / conductor fixed type and a single / conductor variable insulating rod of 2 to 5 steps in units of about 50 cm, of which FIG. 5 illustrates a conventional corrugated fixed polymer phase spacer.

종래 이 같은 폴리머 상간스페이서는 아이로드(101)로 서로 연결된 코아(103)의 양단에 크레비스 로드(104)가 배치되고, 이 크레비스 로드(104)의 끝단에 삼각요크(105)가 연결되며, 이 삼각요크(105)의 밑면 양쪽 꼭지부에 송전선로의 전력선이 이 삽입 관통되는 전선 클램프(106)에 연결된 크레비스 링크(107)가 각각 설치되어 있었다.In the conventional polymer phase spacer, a crevis rod 104 is disposed at both ends of the core 103 connected to each other by an eye rod 101, and a triangular yoke 105 is connected to an end of the crevis rod 104.

In addition, there is a shortage of preventing the voltage drop caused by a short circuit failure in accordance with the trend of increasing the customer's level of demand for electrical quality.
