본 고안은 지하 전력구에 설치된 케이블을 화재로부터 보호하기 위한 것으로서, 더욱 상세하게는 배전케이블의 과부하나 케이블 접속부의 발열에 의해 발생되는 화재로부터 송전케이블을 보호하기 위해 송전케이블의 상부에 씌움 설치되는 케이블 보호 차화판에 관한 것이다.The present invention is to protect the cable installed in the underground power outlet from the fire, and more specifically, it is installed on the top of the power transmission cable to protect the power transmission cable from fire caused by overload of the distribution cable or heat generation of the cable connection portion A cable protection shield board.
일반적으로 배전선로를 인출하는 154KV 배전 변전소로부터 154KV 송전 케이블과 22.9KV 배전케이블이 지하전력구로 병행 설치되는데, 그 구조가 제1도와 같이 상하로 층층이 배선될 수 있도록 된 행거(17)의 상부 위치에 22.9KV의 배전케이블(11)이 설치되고, 하부에 154KV의 송전케이블(10)이 설치된다. 또한 전기 부하가 많이 걸리는 배전선로는 과부하로 인한 과열과 케이블접속부에 먼지와 같은 이물질이 쌓이게 되어 화재의 위험성이 도사리고 있으며, 또한 베전케이블에 발화가 될 경우, 그 불똥이 하부로 떨어져 화재에 취약한 가교폴리에틸렌 또는 오일 필드 케이블 구조로 되어 있는 무수히 많은 송전케이블에 옮겨 붙어 화염이 급속도로 확산되므로 지하 전력구에 설치된 소화탐지기가 작동하여 하론가스를 터트려 화재를 진압한다 해도 송전케이블의 피복이 손상을 입어 복구에 상당한 시간이 소요되고 상당기간 전원공급 불능상태가 되므로 막대한 피해를 입게 되는 폐단이 있었다. 또한 이를 막기 위해 송전케이블을 불연성소재를 사용할 수도 있으나 이는 고가이므로 설치비용이 너무 많이 소요되는 문제점이 있었다.In general, a 154KV power transmission cable and a 22.9KV power distribution cable are installed in parallel with an underground power outlet from a 154KV power distribution substation which draws a distribution line, and the structure is located at the upper position of the hanger 17 such that the structure can be layered up and down as shown in FIG. A power distribution cable 11 of 22.9 KV is installed, and a power transmission cable 10 of 154 KV is installed below. In addition, the distribution line, which is heavily loaded with electrical loads, may cause overheating due to overload and foreign matters such as dust on the cable connection, which may cause a fire. The flame spreads rapidly because it is transferred to a large number of transmission cables of polyethylene or oil field cable structure, and the fire extinguishing detector installed in the underground power outlet operates, and even if the fire is extinguished by blowing down the halon gas, the cover of the transmission cable is damaged and recovered. It took a lot of time, and for a long time, the power supply was incapacitated. In addition, to prevent this, it is possible to use a non-combustible material for the transmission cable, but this is expensive, there was a problem that takes too much installation cost.
따라서 본 고안은 상기와 같은 폐단을 해소하고자 안출된 것으로 상부의 배전케이블에 발생된 화염이 송전케이블에 옮겨 붙지 못하도록 보호하는 차화막을 설치하고,또한 케이블이 행거 하부로 늘어짐을 방지하는 그목적이 있다.Therefore, the present invention is designed to solve the above-mentioned end, and installs a shielding film to protect the flame generated in the upper distribution cable from being transferred to the transmission cable, and also prevents the cable from sagging down the hanger. .
상기한 목적을 달성하기 위한 본 고안은 송전케이블의 상부를 덮을 수 있는 구조로 된 난연성판으로 되고, 반원통형의 차화판을 형성하여 그 일측의 단부에는 소정의 폭을 갖는 반원통의 소켓판을 차화판의 내외면에 겹쳐지게하여 소켓부를 형성하고, 차화판의 종단부가 2매의 소켓판 사이에 잘반만 끼워지게 하여 볼트를 체결하므로서 차화판에 동일 형상의 요홈부가 형성되게 하고, 이에 대응하는 다른 판의 일단이 기밀하게 끼워지는 그 구로 길이방향으로 연속되게 연결 설치한다.The present invention for achieving the above object is a flame-retardant plate having a structure that can cover the upper portion of the power transmission cable, and forms a semi-cylindrical shield plate and a semi-cylindrical socket plate having a predetermined width at one end thereof The socket part is formed by overlapping the inner and outer surfaces of the shield plate, and the end of the shield plate is sandwiched only between two socket plates to fasten the bolts so that the grooves of the same shape are formed on the shield plate. One end of the other plate is connected to the sphere in a longitudinal direction and is installed continuously.
또한 케이블의 행거의 공간하부로 늘어짐을 방지하고,상기 차화판과의 결속을 위해 결속구가 구비된 결속밴드가 장치된다.In addition, the hanger of the cable is prevented from hanging down, and the binding band is provided with a binding port for binding with the shield plate.
이하 본 고안의 바람직한 실시예를 첨부도면과 함께 상세히 설명하면 다음과 같다.Hereinafter, described in detail with reference to the accompanying drawings a preferred embodiment of the present invention.
먼저 행거(17)의 상부에 설치된 송전케이블(10)의 상부를 덮는 차화판(12)은 반원통형으로 형성하여 일측의 단부에서 소정의 폭을 갖는 반원통형의 소켓판(131)을 차화판(12)의 내외면에 겹쳐지게 하여 소켓부(13)를 형성하고, 상기 차화판(12)의 종단부가 2매의 소켓판(131) 사이에 절반만 끼워지게 하여 볼트(132)로 체결함에 따라 차화판(13)에 동일 형상의 요홈부(133)가 형성되게 하여서 된다.(제3도 참조)First, the shielding plate 12 covering the upper portion of the power transmission cable 10 installed on the top of the hanger 17 is formed in a semi-cylindrical shape to form a semi-cylindrical socket plate 131 having a predetermined width at one end thereof. The socket part 13 is formed by overlapping the inner and outer surfaces of the 12), and the terminal part of the hardening plate 12 is sandwiched between the two socket plates 131 by only half and fastened with the bolt 132. The grooves 133 having the same shape are formed on the shield plate 13. (See FIG. 3)
또한 상기의 대응되는 요홈부(133)에 다른 차화판(12)의 일측단이 기밀하게 끼워져 길이방향으로 연속되게 결합설치되며, 상기 차화판(12)과 그 하부의 송전케이블(10)처침을 방지하고, 양호한 결속력을 주기 위해 인장강도와 내구성이 뛰어난 스테인리스강판이면서 결속구(15)를 구비한 결속밴드(14)가 길이방향으로 일정한 간격으로 설치된다.In addition, one side end of the other shield plate 12 is hermetically fitted to the corresponding recess 133 to be installed in a continuous manner in the longitudinal direction, and the drop plate 12 and the power transmission cable 10 at the bottom thereof are disposed. In order to prevent and give a good binding force, the binding band 14 which is a stainless steel sheet excellent in tensile strength and durability, and which has the binding port 15 is installed at regular intervals in the longitudinal direction.
상기한 구성에 의한 본 고안의 사용상태를 설명하면 다음과 같다.Referring to the state of use of the subject innovation according to the above configuration is as follows.
먼저, 지하 전력구의 행거에 층층이 배전설치된 송전케이블(10)의 상부로 차화판(12)을 씌우고, 그 일측에 형성된 소켓부(13)에 대응되는 다른 차화판(12)의 일측단을 삽입하여 틈새가 없도록 기밀하게 연결 설치한 후 차화판(12)이 송전케이블(10)로부터 이탈되지 않도록 서로를 결속밴드(14)로 감은 후 클립과 같은 결속구(15)로 체결하여 견고하게 결속되도록 한다.First, cover the circuit board 12 to the upper portion of the power transmission cable 10, the layered layer is installed on the hanger of the underground power outlet, and insert one end of the other shield plate 12 corresponding to the socket portion 13 formed on one side thereof. After installing the airtight connection so that there is no gap, wind the board 12 together with the binding band 14 so as not to be separated from the power transmission cable 10, and then fasten it with a binding hole 15 such as a clip so as to be firmly bound. .
따라서 상기 지하 전력구의 행거상부에 배전설치된 배전케이블에 과부하로 인한 과열이나 ,케이블 접속부에 먼지와 같은 이물질이 쌓여 과열에 의해 화재가 발생하는 등 여러 요인에 의해 화재가 발생하면 상기 배전케이블을 피복하고 있는 합성수지가 타면서 그 불똥이 하부로 떨어지는데 이는 송전 케이블(10)의 상부에 기밀하게 연결 결합된 난연성 케이블 차화판(12)에 의해 차단되어 절대로 옮겨 붙지 않는다.Therefore, if a fire occurs due to various factors such as overheating due to overload in a distribution cable installed in the upper part of the hanger of the underground power outlet, or foreign matter such as dust accumulated in the cable connection part, the fire may be caused by various factors such as covering the distribution cable. As the synthetic resin burns down, the spark falls to the bottom, which is blocked by the flame-retardant cable shield plate 12 which is tightly connected to the upper portion of the power transmission cable 10 and never moves.
이상에서와 같이 본 고안은 지하 전력구에 조밀하게 설치된 케이블을 난연성 차화판으로 덮어 배전케이블의 과열이나 다른 원인에 의해 발생된 화재로부터 확실하게 보호할 있으므로 배전선에 부득이 화재가 발생하더라도 그 피해를 최대한 줄일 수 있는 장접이 있는 것이다.As described above, the present invention covers a cable installed densely in an underground power outlet with a flame-retardant panel to reliably protect it from fire caused by overheating of the distribution cable or other causes. There is a deduction that can be reduced.
