본 발명은 맨홀에 고압케이블 연결관 이음장치를 설치시 맨홀 내부에 누수 발생 및 송배전 고압케이블의 누전사고를 방지하기 위한 변전소의 송배전 고압케이블 연결관 이음장치에 관한 것이다.The present invention relates to a transmission and distribution high voltage cable connector of the substation for preventing the leakage of the inside of the manhole and the leakage of the high voltage cable of the transmission and distribution when installing the high voltage cable connector fitting in the manhole.

일반적으로 각 가정이나 사무실 등에서 사용되는 전기는 각 지역별로 설비되어 있는 변전소로부터 제공되고 있다.In general, electricity used in each home or office is provided by substations installed in each region.

즉, 변전소는 발전소에서 생산한 전력을 송전선로나 배전선로를 통하여 수용가에게 보내는 과정에서 전압이나 전류의 변성 및 전력의 배분을 위하여 설치되는 시설이라 할 수 있으며, 상기 변전소는 154KV, 23KV용 현장설비로 나뉘어지며, 23KV 변전소를 통해 각 부하(소비자)로 전기가 공급된다.In other words, the substation is a facility that is installed for the distribution of voltage or current and the distribution of power in the process of sending the power produced by the power plant to the customer through the transmission line or distribution line, the substation is a field equipment for 154KV, 23KV It is divided and supplied to each load (consumer) through a 23KV substation.

한편, 변전소는 통상 지상 구조를 갖고 있으나, 고압전선이 외부로 노출됨에 따른 위험성이 대두되면서 현재에는 집단 민원과 도시 미관을 해친다는 이유로 지 하에 설치되는 경우가 점차 늘어나고 있는 실정이다.On the other hand, substations usually have a ground structure, but as the danger of exposure to high-voltage lines increases, they are increasingly being installed underground because they undermine group complaints and urban aesthetics.

이와 같이 변전소를 지하에 설치하게 되면, 고압케이블을 설치하는 과정에서 주변의 지형에 따라 절단한 후 다시 연결하여 사용하는 경우가 빈번하게 발생하고 있다. 또한, 최초에 설계한 고압케이블의 길이가 현장 여건에 따라 더 소요되므로, 고압케이블을 더 연결하여 사용하는 경우 또한 자주 발생하고 있다.When the substation is installed in the basement as described above, in the process of installing the high-voltage cable, it is frequently used to cut and reconnect according to the surrounding terrain. In addition, since the length of the initially designed high-voltage cable takes longer depending on the site conditions, it is also frequently used to connect more high-voltage cable.
