Description

냉각장치를 구비하는 초고압 변압기를 갖춘 변전설비{EQUIPMENT FOR TRANSFORMATION}[0001] EQUIPMENT FOR TRANSFORMATION [0002] FIELD OF THE INVENTION [0003]

본 발명은 냉각장치를 구비하는 초고압 변압기를 갖춘 변전설비에 관한 것이다.The present invention relates to a substation equipped with an ultra-high voltage transformer having a cooling device.

변전소란, 발전소에서 발생한 전력을 경제적인 송전을 하기 위해 전압을 높이거나 낮추어 수송하는 장소를 말하며, 변전소의 설치 목적은 전압의 승압 및 강압, 전력의 집중과 배분, 전력 계통을 보호하기 위해서이다. A substation is a place where electric power generated by a power plant is transported by increasing or decreasing a voltage for economical transmission. The purpose of installation of a substation is to protect voltage and pressure, power concentration and distribution, and power system.

이러한 변전소에는 초고압 변압기가 구비되어, 발전소로부터의 전력을 변전한다. 예를 들어 기간 계통 변전소는 발전소로부터 전력을 집중하고 초고압 변압기를 이용하여 345[kV]나 765[kV]로 승압한 후 다른 동일한 변전소로 전력을 송전한다.Such a substation is equipped with an extra-high voltage transformer to transform power from the power plant. For example, a substation substation concentrates its power from a power plant and boosts it to 345 [kV] or 765 [kV] using an ultra-high voltage transformer and then transfers power to the same substation.

한편 상기 변압기는 부싱과 엘보 접속재를 매개로 송전선과 연결되어, 발전소로부터의 전기를 공급받는다.On the other hand, the transformer is connected to a transmission line via a bushing and an elbow connection member, and receives electricity from the power plant.

그러나 이러한 변압기는 비가 내릴 시 우수에 의해 누전이 발생할 수 있어 매우 위험하다. 또한 상기 변압기는 내부 열이 증가할 수 있는 데 이를 신속하게 냉각해 주지 않으면, 폭발의 위험성이 있다.However, such a transformer is very dangerous because it may cause a short circuit due to rain during rain. Also, the transformer can increase the internal heat, and if it does not cool quickly, there is a risk of explosion.

따라서 절연성을 향상시키고, 폭발의 위험을 낮출 수 있는 안정적인 변전설비의 필요성이 꾸준히 제기되고 있다. Therefore, there is a continuing need for a stable substation facility capable of improving the insulation and reducing the risk of explosion.

Meanwhile, in the present embodiment, the insulating oil is accommodated in the insulating oil accommodating space 130, but the insulating oil may not be accommodated.

상판(110)은 상하방으로 개구된 삽입홀(111)과, 삽입홀(111)의 하부에 구비되어 삽입홀(111)과 연통되며 측방으로 형성되는 상부유로(112)를 갖춘다. 이때 상부유로(112)는 물이 흐르면서 냉각작용을 하도록 한다.The upper plate 110 is provided with an insertion hole 111 opened upward and downward and an upper passage 112 provided at a lower portion of the insertion hole 111 and communicating with the insertion hole 111 and laterally formed. At this time, the upper flow path 112 allows the cooling operation to be performed as the water flows.

측판(120)은 상판(110)의 상부유로(112)의 일측에 연통되고 하방으로 형성되는 측부유로(121)와, 측부유로(121)의 하측에 연통되며 외측방으로 개구되는 개구홀(122)을 갖춘다. 본 실시예에서는 전력공급이 이루어지는 판을 제외하고 3개의 측판(120)이 연결되도록 구비된다. 이때 측부유로(121)는 물이 흐르면서 냉각작용을 하도록 한다.The side plate 120 includes a side flow path 121 communicating with one side of the upper flow path 112 of the upper plate 110 and formed downwardly and an opening hole 122 communicating with the lower side of the side flow path 121, ).

연결부(210)는 측방으로 개구된 순환라인연결홀(211)을 구비하고, 냉각기구(100)의 삽입홀(111)에 착탈가능하게 설치되며, 파이프 형상을 이룬다. The connection part 210 has a circulation line connection hole 211 opened sideward and is detachably installed in the insertion hole 111 of the cooling mechanism 100 and has a pipe shape.

가이드부(220)는 상방으로 개구되고, 하방으로 갈수록 경사지며, 냉각기구(100)의 폭 보다 크고, 연결부(210)의 상부에 구비되어 연결부(210)와 연통된다. 이때 가이드부(220)는 냉각기구(100)의 폭 보다 크기 때문에 우수가 냉각기구(100)에 직접 닿는 것을 방지한다.The guide portion 220 is opened upward and is inclined downward and is larger than the width of the cooling mechanism 100 and is provided at an upper portion of the coupling portion 210 to communicate with the coupling portion 210. At this time, since the guide part 220 is larger than the width of the cooling mechanism 100, it prevents the rain from directly touching the cooling mechanism 100.

돌출부(230)는 가이드부(220)의 측면 둘레부를 따라 구비되고, 상방으로 돌출된다.The protruding portion 230 is provided along the side circumferential portion of the guide portion 220 and protrudes upward.

제2지지부재(320)는 내측으로 개구된 스프링수용홈(321)을 구비하며, 제1지지부재(310)에 대향되도록 우수수용기구(200)의 돌출부(230)의 내측에 설치된다.The second support member 320 has a spring receiving groove 321 opened to the inside and is installed inside the protrusion 230 of the water tank 200 so as to face the first support member 310.

거름망(330)은 일단이 제1지지부재(310)의 스프링수용홈(311)에 상하이동가능하게 설치되고, 타단이 제2지지부재(320)의 스프링수용홈(321)에 상하이동가능하게 설치된다. 이때 거름망(330)은 우수와 포함되어 유입되는 이물질을 거른다.One end of the filtering wire 330 is vertically movable in the spring receiving groove 311 of the first supporting member 310 and the other end thereof is vertically movable in the spring receiving groove 321 of the second supporting member 320 Respectively. At this time, the screening filter 330 filters the foreign matter contained in the rainwater.

제1하부스프링(340)은 제1지지부재(310)의 스프링수용홈(311)의 하부에 설치되어 거름망(330)을 상방으로 탄발지지한다. The first lower spring 340 is installed at a lower portion of the spring receiving groove 311 of the first supporting member 310 to elastically support the drawing wire 330 upward.

제1상부스프링(350)은 제1지지부재(310)의 상부에 설치되어 거름망(330)을 하방으로 탄발지지한다.The first upper spring 350 is installed on the upper portion of the first supporting member 310 to elastically support the filtering wire 330 downward.

제2하부스프링(360)은 제2지지부재(320)의 스프링수용홈(321)의 하부에 설치되어 거름망(330)을 상방으로 탄발지지한다.The second lower spring 360 is installed at a lower portion of the spring receiving groove 321 of the second supporting member 320 to elastically support the drawing wire 330 upward.

제2상부스프링(370)은 제2지지부재(320)의 스프링수용홈(321)의 상부에 설치되어 거름망(330)을 하방으로 탄발지지한다.The second upper spring 370 is installed at an upper portion of the spring receiving groove 321 of the second supporting member 320 to elastically support the filtering wire 330 downward.

이때 상기 제1하부스프링(340), 제1상부스프링(350), 제2하부스프링(360), 제2상부스프링(370)은 거름망(330)에 우수 및 이물질이 낙하할 시 발생하는 진동을 완충하여, 상기 발생하는 진동이 변압기(T)에 전달되지 않도록 함으로써, 변압기(T)가 보다 안정적으로 구동되도록 한다. At this time, the first lower spring 340, the first upper spring 350, the second lower spring 360, and the second upper spring 370 move the vibration generated when the rainwater and the foreign matter fall on the water line 330 So that the generated vibration is not transmitted to the transformer T, so that the transformer T is more stably driven.
