본 발명은 변전소 전력콘덴서 단자부식 방지용 튜브설치구조에 관한 것으로서, 특히 변전소 전력콘덴서의 애자 상단에 형성된 단자에 물기나 먼지가 침투하여 상기 단자가 부식되는 것을 방지할 수 있는 변전소 전력콘덴서 단자부식 방지용 튜브설치구조에 관한 것이다.The present invention relates to a tube installation structure for preventing corrosion of substation power capacitor terminals, and in particular, a substation power capacitor terminal corrosion prevention tube that can prevent corrosion of the terminal by infiltration of water or dust into a terminal formed on the insulator upper end of the substation power capacitor. It relates to the installation structure.

일반적으로, 변전소란 발전소에서 생산한 전력을 송전선로나 배전선로를 통하여 수요가에게 보내는 과정에서 전압이나 전류의 변성 및 전력의 배분을 위하여 설치하는 시설의 집합체를 말한다.In general, a substation is a collection of facilities 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 demand through transmission lines or distribution lines.

이렇게 전력을 발전소에서 수요가까지 수송하기 위하여는 비교적 장거리의 송전선로를 통과해야 하는데, 이 때 필연적으로 선로의 저항과 선로를 흐르는 전류의 제곱의 곱에 상당하는 손실이 발생된다. 이 송전손실을 줄이기 위하여는 전선을 굵은 것으로 사용하여 저항을 작게 하거나 송전전압을 높게 하여 동일 전력 수송시 전류를 작게 하는 방법이 사용된다.In order to transport power from a power plant to demand, it is necessary to pass a relatively long transmission line, which inevitably causes a loss corresponding to the product of the resistance of the line and the square of the current flowing through the line. In order to reduce this transmission loss, a thick wire is used to reduce the resistance or to increase the transmission voltage to reduce the current during the same power transportation.

한편, 발전소의 전압은 제작비용 등을 고려하여 통상 2만~3만V 사이의 값을 가지게 되며 이 전압을 송전전압으로 높여서 송전한다. 한국의 송전전압은 66,000V, 154,000V 및 345,000V 등이며 앞으로 765,000V 송전선로를 건설할 계획이 다. 이와 같은 높은 전압으로 일반 가정까지 전력을 수송할 수 없으므로 변전소에서는 이들 전압을 배전전압(한국의 경우 주로 22,900V이며 일부 지역에서는 6,600V임)으로 낮추어 배전하며, 이 배전전압을 주상변압기 등을 통하여 110V 또는 220V로 낮추어 가정에서 전기를 사용한다. On the other hand, the voltage of the power plant usually has a value between 20,000 to 30,000V in consideration of manufacturing costs, etc., and the power is increased by increasing the voltage to the transmission voltage. The transmission voltages in Korea are 66,000V, 154,000V, and 345,000V, and 765,000V transmission lines are planned to be constructed. Since such high voltages cannot transport power to ordinary homes, the substation lowers these voltages to the distribution voltage (22,900V in Korea and 6,600V in some areas) and distributes this voltage through a column transformer. Lower it to 110V or 220V to use electricity at home.

이상과 같이 발전전압을 송전전압으로 높이는 변전소를 승압변전소라 하고, 송전전압을 배전전압이나 더 낮은 송전전압으로 낮추는 변전소를 강압변전소라 한다. 강압변전소 중에서 그 기능에 따라 송전전압을 더 낮은 송전전압으로 낮추는 변전소를 1차 변전소라 하며, 송전전압을 배전전압으로 바꾸는 변전소를 2차 변전소라고도 한다.As described above, substations that raise the generation voltage to the transmission voltage are called boost substations, and substations that lower the transmission voltage to the distribution voltage or lower transmission voltage are called substations. Substations that lower the transmission voltage to lower transmission voltages according to their function are called primary substations. Substations that convert transmission voltages to distribution voltages are also called secondary substations.

l차변전소에서는 일반적으로 전압을 조정하는 것이 주목적인데, 이러한 목적을 실현하기 위하여 조상기(調相機) 또는 대용량의 전력콘덴서가 설비된다.In the primary substation, the main purpose is to adjust the voltage. In order to achieve this purpose, an ancestor or a large capacity power capacitor is installed.

그러나, 상기와 같은 종래의 변전소 전력콘덴서는 케이블과 단자의 연결부분에 수분이나 먼지가 침투하여 그 연결부에 쉽게 녹이 발생되는 문제점이 있다.However, the conventional substation power capacitor as described above has a problem in that moisture or dust penetrates into the connection portion of the cable and the terminal, thereby easily causing rust.

본 발명은 상기한 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 단자와 케이블의 연결부가 수분이나 먼지 등과 같은 외부 환경요인과 차단될 수 있도록 튜브를 설치하여 상기 연결부의 부식을 방지할 수 있는 변전소 전력콘덴서 단자부식 방지용 튜브설치구조를 제공하는데 그 목적이 있다.The present invention has been made to solve the problems of the prior art, a substation that can prevent the corrosion of the connection by installing a tube so that the connection between the terminal and the cable can be blocked from external environmental factors such as moisture or dust.

상기와 같이 구성된 본 발명에 따른 변전소 전력콘덴서 단자부식 방지용 튜브설치구조의 설치과정을 살펴보면 다음과 같다.Looking at the installation process of the substation power capacitor terminal corrosion prevention tube installation structure according to the present invention configured as described above are as follows.

먼저, 단자보호튜브(50)를 애자(20)의 상단에 안착시켜 상기 단자보호튜브(50)가 단자(30)를 감싸도록 한다. 만약 단자보호튜브(50)의 하측부가 너무 좁아서 단자(30)를 상기 단자보호튜브(50)의 중간부에 위치하게 할 수 없다면, 도면에 도시하지는 않았으나 단자보호튜브(50)를 상하방향으로 절개한 후에 상기 단자보호튜브(50)를 벌리고 애자(20)를 감싼다. 그런 다음 조임부재를 이용하여 단자보호튜브(50)의 절개된 부분을 조여주면 된다.First, the terminal protection tube 50 is seated on the top of the insulator 20 so that the terminal protection tube 50 surrounds the terminal 30. If the lower portion of the terminal protection tube 50 is too narrow to allow the terminal 30 to be positioned in the middle of the terminal protection tube 50, the terminal protection tube 50 is cut in the vertical direction although not shown in the drawing. Afterwards, the terminal protection tube 50 is opened and the insulator 20 is wrapped. Then, tighten the cut off portion of the terminal protection tube 50 by using a fastening member.

Let's do it.

이후, 접속캠(64)의 하단을 단자보호튜브(50)의 상단에 끼우고, 연이어 봉합튜브관(62)의 하단을 상기 접속캠(64)의 상단에 끼운다.Thereafter, the lower end of the connection cam 64 is inserted into the upper end of the terminal protection tube 50, and subsequently the lower end of the sealing tube tube 62 is inserted into the upper end of the connection cam 64.

그런 다음, 봉합커플링(66)의 하단을 봉합튜브관(62)의 상단에 끼워 케이블 보호튜브(60)의 내부 공간을 외부환경과 차단시킨다.Then, the lower end of the sealing coupling 66 is inserted into the upper end of the sealing tube tube 62 to block the inner space of the cable protection tube 60 from the external environment.

이렇게 케이블 보호튜브(60)의 내부 공간이 밀폐되면, 봉합튜브관(62)의 주입구(62a)를 통하여 상기 케이블 보호튜브(60)의 내부공간이 완전히 채워질때까지 접속제(70)를 주입시킨다.When the inner space of the cable protection tube 60 is sealed in this way, the connection agent 70 is injected through the inlet 62a of the sealing tube tube 62 until the inner space of the cable protection tube 60 is completely filled. .
