Description

확장형 케이블행거 {Extending cable hanger}Extension cable hanger {Extending cable hanger}

본 고안은 전력구 및 맨홀 내에 설치되어 송배전선로에 전원을 공급하는 전력케이블을 지지하는 확장형 케이블행거에 관한 것으로서, 특히 최초 설치 후 추가회선 인출에 따른 케이블행거의 확장 시 기존의 행거를 철거함이 없이 확장이 가능함은 물론 확장 후 작업공간의 협소에 따른 안전사고가 방지되는 확장형 케이블행거에 관한 것이다.The present invention relates to an extended cable hanger that is installed in a power outlet and a manhole to support a power cable for supplying power to a transmission and distribution line. In particular, the existing hanger is removed when the cable hanger is extended by drawing out additional lines after the initial installation. Expandable cable hanger that can be extended without a safety as well as to prevent safety accidents due to the narrow working space after expansion.

일반적으로 케이블행거는 전력구내 송배전선로나 발전소와 변전소의 케이블 처리실이나 지중화 구간의 맨홀 등에 가설되는 케이블을 지지하는 금구류로서, 이러한 케이블행거는 변전소에서 최종적으로 인출할 수 있는 회선수에 상응하는 규격을 설치함이 원칙이나 도심지역에서는 도로굴착의 제한 및 교통의 영향을 적정 규격의 구조물을 확보하기가 곤란하여 좁은 공간에 상위 규격의 행거를 설치하게 된다.In general, cable hangers are brackets that support cables installed in transmission and distribution lines in power premises, cable processing rooms of power plants and substations, and manholes in underground zones. These cable hangers correspond to the number of lines that can be finally drawn out from the substation. In principle, however, it is difficult to secure a structure of appropriate standard to limit road excavation and traffic influence in urban areas. Therefore, a hanger of higher standard is installed in a narrow space.

그러나 상위규격의 행거를 설치하다 보면, 케이블 신설이나 선로 순시 점검시 작업자 및 순시자의 통행불편으로 작업효율이 저하되어 올바른 시공을 하기가 곤란한 경우가 발생하며, 이를 해소하기 위하여 설치공간에 적합한 케이블 행거를 시설할 경우, 전력 수요 증가에 따른 추가회선 인출시 기존의 행거를 모두 철거하고 상위규격으로 교체함에 따른 공사기간 및 공사비용이 증가될 우려가 있다.However, when installing a higher standard hanger, it is difficult to properly install the cable hanger due to the inconvenience of worker and instantaneous traffic during installation of the cable or the instantaneous inspection of the track. If the facility is installed, there may be an increase in the construction period and construction cost by removing all the existing hangers and replacing them with higher standards when drawing out additional lines due to the increase in electric power demand.

아울러 지중케이블 작업은 전력구나 맨홀 등 협소한 공간에서 작업이 이루어지고 있으며, 내부의 여러 부속자재의 도출로 작업자의 안전이 위협받고 있다. 특히 행거는 단말부가 날카롭게 되어 있어 작업자에게 큰 부담이 되며, 전력구 내에서는 별도의 야광 행거캡을 부착하고 있으나, 선로점검 등 출입시나 기타 작업시 행거캡이 행거에서 분리될 우려가 있으며, 맨홀 내에서는 행거캡 자체가 시설되지 않고 있는 실정으로 순간적인 방심으로 작업자에게 큰 부상을 일으킬 수 있는 요인이 상존하고 있다.In addition, underground cable work is being carried out in narrow spaces such as electric power or manholes, and the safety of workers is threatened by the derivation of various internal materials. In particular, the hanger has a sharp end, which is a great burden to the worker.In the electric power district, a separate luminous hanger cap is attached.However, the hanger cap may be separated from the hanger during entry or other work such as track inspection. In the hanger cap itself is not equipped with the fact that there is a factor that can cause a great injury to the workers with a momentary carelessness.

즉, 종래의 케이블행거는 몸체에 상하방향으로 다수개의 보울트공이 형성된 체결부와, 체결부에 일체 또는 매개부재를 통해 연결된 지지부로 구성되어, 체결부를 지지대의 설치개소에 맞댄 상태에서 보울트로 체결하여 지지부를 수평상태로 유지시킨 다음, 지지부의 상부측에 전력케이블을 안착시키는 것이다.That is, the conventional cable hanger is composed of a fastening portion formed with a plurality of bolt holes in the body in the up and down direction, and a support portion connected to the fastening portion integrally or through an intermediate member, and fastening the fastening portion with the bowl in a state where the fastening portion is opposed to the installation point of the support. The support is kept horizontal, and then the power cable is seated on the upper side of the support.

그러나 상기 종래의 케이블행거는 수평으로 유지되는 지지부의 길이를 길게할 경우, 출입시 통로의 어려움과 지지부 끝단에 작업자가 상해를 입는 문제점이 있었다. 아울러 지지부를 짧게할 경우 회선의 증가시 케이블행거 전체를 교체하는 불편한 문제점이 있었다.However, in the conventional cable hanger, when the length of the support portion to be maintained horizontally, there is a problem of difficulty in passage and injuries of workers at the end of the support portion when entering and exiting. In addition, when the support is shortened, there was an uncomfortable problem of replacing the entire cable hanger when the line was increased.
