Description

변전소 전력 콘센트 단자부식 방지용 구형튜브{Spherical tube for terminal corrosion protection of power outlet of transforming station}Spherical tube for terminal corrosion protection of power outlet of transforming station

본 발명은 변전소 전력 콘센트 단자부식 방지용 구형튜브에 관한 것으로서, 보다 상세하게는 전력 콘덴서의 단자와 케이블의 연결부에 전후방측 구형튜브몸체와 몸체회동받침링 및 상부마감밀폐캡과 케이블신축보호관을 형성시킴으로써 연결부가 수분이나 먼지 등과 같은 외부 환경요인과 최대한 차단될 수 있도록 하여 연결부의 부식을 근본적으로 방지할 수 있어 유지비용을 최대한 절감시킬 수 있는 변전소 전력 콘센트 단자부식 방지용 구형튜브에 관한 것이다. The present invention relates to a spherical tube for preventing corrosion of a substation power outlet terminal, and more particularly, by forming a front and rear spherical tube body and a body rotation support ring, an upper closure sealing cap, and a cable extension protection tube at a connection portion of a terminal and a cable of a power condenser. The present invention relates to a spherical tube for preventing corrosion of a substation power outlet terminal, which can reduce maintenance costs as much as possible by allowing the connection part to be blocked from external environmental factors such as moisture or dust as much as possible, thereby fundamentally preventing corrosion of the connection part.

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 refers to an assembly of facilities installed for the transformation of voltage or current and distribution of power in the process of sending power produced by a power plant to a consumer through a transmission line or distribution line.

이렇게 전력을 발전소에서 수요가까지 수송하기 위하여는 비교적 장거리의 송전선로를 통과해야 하는데, 이때 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 electric power from the power plant to the demand price in this way, it must pass through a relatively long transmission line, inevitably, a loss equivalent to the product of the square of the resistance of the line and the current flowing through the line is generated. In order to reduce the transmission loss, a method of reducing the resistance by using a thick wire or increasing the transmission voltage to reduce the current when transporting the same power is used.

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 계획이다. On the other hand, the voltage of the power plant usually has a value between 20,000 ~ 30,000V in consideration of manufacturing cost, etc., and this voltage is raised to the transmission voltage and transmitted. Korea's transmission voltage is 66,000V, 154,000V, and 345,000V, and 765,000V transmission lines are planned to be built in the future.

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. Since electricity cannot be transported to general households with such a high voltage, the substation reduces these voltages to the distribution voltage (mainly 22,900V in Korea and 6,600V in some areas) and distributes the distribution. 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, a substation that increases the power generation voltage to a transmission voltage is referred to as a step-up substation, and a substation that decreases the transmission voltage to a distribution voltage or a lower transmission voltage is referred to as a step-down substation. Among the step-down substations, a substation that lowers the transmission voltage to a lower transmission voltage according to its function is called a primary substation, and a substation that converts the transmission voltage into a distribution voltage is also called a secondary substation.

l차변전소에서는 일반적으로 전압을 조정하는 것이 주목적인데, 이러한 목적을 실현하기 위하여 조상기(調相機) 또는 대용량의 전력콘덴서가 설비된다. 상기 전력콘덴서의 상단에는 송전선이나 전기기기의 나선 부분을 절연하고 동시에 기계적으로 유지 또는 지지하기 위하여 자기로 만든 애자가 설치되고, 상기 애자에는 케이블과 연결되는 단자가 설치된다. In the primary substation, the main purpose is to adjust the voltage in general, and to achieve this purpose, an ancestor or a large-capacity power capacitor is installed.
