현재까지 상용화된 변압기 냉각방법은 공냉식, 풍냉식, 송유풍냉식 및 수냉식이 적용되고 있으며 본 발명자는 실용신안등록 제375025호(2005.01.26), 제378014호(2005.02.28) 및 제385032호(2005.05.16) 등을 통하여 폐회로냉동사이클 및 온도차발전냉동사이클이 적용된 변압기 냉각장치를 고안한 바 있다. 그러나 고안들에 적용된 것은 냉동사이클이다. 냉동사이클을 사용하면 압축기를 필히 사용하여야 하며 응축기에서 제거시켜야 하는 열은 변압기에서 빼앗아 온 열에 압축기가 행한 일에 해당하는 열을 추가한 것이 되어 응축기가 커지는 단점이 있다.Commercially available transformer cooling methods are air-cooled, wind-cooled, oil-cooled, and water-cooled. The present inventors have applied for utility model registration Nos. 375025 (January 26, 2005), 378014 (October 28, 2005) and 385032 ( 2005.05.16) has devised a transformer cooling system to which closed-loop refrigeration cycle and temperature-differential generation refrigeration cycle are applied. But what has been applied to the designs is the refrigeration cycle. If a refrigeration cycle is used, the compressor must be used and the heat to be removed from the condenser has a disadvantage in that the condenser becomes large because heat added to the heat taken from the transformer is added to the work performed by the compressor.

본 발명에서는 변압기의 온도에 대한 운전기준은 상온보다 훨씬 높은 온도인 95℃ 정도이므로 변압기를 냉각한다고 하더라도 냉각대상인 변압기 온도를 응축시 키는 대기온도 보다 높게 유지해도 상관이 없으므로 냉동사이클 보다는 역냉동사이클인 발전랭킨사이클을 적용하는 것을 고려한다. 변압기 냉각에 있어서 냉동사이클이나 발전랭킨사이클이나 변압기로부터 취득한 열을 최종적으로 응축기에서 공기 또는 물로 제거시켜야 한다. 이 경우 응축기는 변전소 구내에 설치되어야 하므로 응축기도 설치공간을 필요로 하므로 효과적인 변압기 냉각장치를 구현하기 위해서는 응축기를 최소화하는 방안을 고려한다. 또한 기존의 변압기방열기를 활용하여 본 고안에 의한 냉각장치가 가동되지 않을 경우에도 냉각성능을 발휘하는 방법을 강구한다.In the present invention, since the operating standard for the temperature of the transformer is about 95 ° C., which is much higher than room temperature, even if the transformer is cooled, it does not matter whether the temperature of the transformer to be condensed is kept higher than the atmospheric temperature. Consider applying phosphorus-generated Rankine cycles. In transformer cooling, the heat obtained from refrigeration cycles, power generating cycles or transformers must be finally removed from the condenser with air or water. In this case, the condenser must be installed in the substation premises, so the condenser also needs a space for installation. Therefore, in order to implement an effective transformer cooling system, the condenser must be minimized. In addition, by using a conventional transformer radiator, even if the cooling device according to the present invention is devised a method of exhibiting the cooling performance.

도1은 본 발명의 발전랭킨사이클을 활용한 변압기 냉각장치 설명도이다. 절연유 또는 절연가스를 저장하는 변압기(또는 방열판)(10)의 절연유 또는 절연가스는 순환펌프(12)의 작동에 변압기(또는 방열판)(10)와 보일러용열교환기(13) 1차측 사이를 순환관(11)을 통하여 순환하면서 열교환에 의해 보일러용열교환기(13) 2차측에 유입되는 작동유체를 끓인다. 본 발명에 사용되는 작동유체는 냉동사이클에 사용되는 냉매나 액화가스 등을 사용한다. 보일러용열교환기(13) 2차측에 유입된 작동유체는 1차측에 유입 되어 순환되는 변압기의 절연유 또는 절연가스로부터 열을 흡수하여 끓어 기체가 되며 압력조절밸브(14)에 의해 압력과 비등점이 조절된다. 기화된 작동유체는 압력조절밸브(14)를 통하여 넓은 공간을 가진 팽창기(15)로 유입되어 단열팽창 되고 그 내부에 설치된 터빈 등의 기계장치에 일을 행하고 에너지를 일부 상실하고 응축기(16)로 유입되어 열을 빼앗기고 액체상태로 상태변화를 한다. 액화된 작동유체는 작동유체탱크(17)로 유입되고 작동유체공급펌프(18)에 의해 작동유체량조절밸브(19)를 거쳐 보일러용열교환기(13)에 유입되어 냉각의 한 사이클을 종료한다.1 is an explanatory view of a transformer cooling device utilizing the power generation Rankine cycle of the present invention. The insulating oil or insulating gas of the transformer (or heat sink) 10 storing the insulating oil or insulating gas is circulated between the transformer (or heat sink) 10 and the primary side of the heat exchanger 13 for the boiler during operation of the circulation pump 12. Boil the working fluid flowing into the secondary side of the heat exchanger for the boiler 13 by heat exchange while circulating through the pipe 11. The working fluid used in the present invention uses a refrigerant or liquefied gas used in a refrigeration cycle. The working fluid flowing into the secondary side of the boiler heat exchanger (13) absorbs heat from the insulating oil or insulating gas of the transformer, which flows into the primary side, and boils to become a boiling gas, and the pressure and boiling point are controlled by the pressure regulating valve (14). do. The vaporized working fluid flows into the inflator 15 having a large space through the pressure regulating valve 14 to insulate and expand adiabatic and to work on a mechanical device such as a turbine installed therein. It flows in and loses heat and changes its state to a liquid state. The liquefied working fluid flows into the working fluid tank 17 and enters the boiler heat exchanger 13 through the working fluid flow control valve 19 by the working fluid supply pump 18 to end one cycle of cooling.

도 2는 냉동사이클의 P-h선도 설명도이다. 냉동사이클에서 증발기의 압력(Pe)과 온도는 응축기의 압력(Pc)과 온도 보다 낮다. 그렇지만 변압기에서는 증발기와 접하는 변압기절연유 온도를 응축기가 접하는 대기온도 보다 낮게 유지할 이유가 없다. 또한 응축기가 제거해야 하는 열량(Ec)은 변압기로부터 취득한 열량(Ee)에 압축기가 행한 일에 상응하는 열량(Ep)을 추가하여 응축기가 커지는 단점이 있다.2 is an explanatory view of a Ph diagram of a refrigeration cycle. In the refrigeration cycle, the pressure (P e ) and temperature of the evaporator are lower than the pressure (P c ) and temperature of the condenser. However, in a transformer, there is no reason to keep the temperature of the transformer oil in contact with the evaporator below the ambient temperature in contact with the condenser. In addition, the heat amount E c that the condenser needs to be removed has a disadvantage in that the condenser becomes large by adding a heat amount E p corresponding to the work done by the compressor to the heat amount E e obtained from the transformer.

도 3은 랭킨사이클의 P-h선도 설명도이다. 랭킨사이클에서 보일러의 압력(Pb)과 온도는 응축기의 압력(Pc)과 온도 보다 높다. 따라서 변압기에서는 보일러와 접하는 변압기절연유 온도는 응축기가 접하는 대기온도 보다 높게 유지할 수 있다. 또한 응축기가 제거해야 하는 열량(Ec)은 변압기로부터 취득한 열량(Eb)에서 팽창기 내부에 존재하는 기기가 외부로 행한 일에 상응하는 열량(Eg)을 차감한 값이 되므로 응축기가 작아지는 장점이 있다.3 is an explanatory diagram of a Ph diagram of a Rankine cycle. In the Rankine cycle, the pressure (P b ) and temperature of the boiler are higher than the pressure (P c ) and temperature of the condenser. Therefore, in the transformer, the temperature of the transformer insulating oil in contact with the boiler can be maintained higher than the ambient temperature in contact with the condenser. In addition, the amount of heat (E c ) that the condenser needs to be removed is equal to the amount of heat (E b ) obtained from the transformer minus the amount of heat (E g ) corresponding to the work done outside of the equipment inside the expander by the condenser. There is an advantage.

도 4는 서지드럼(Surge Drum)이 추가된 변압기 냉각장치 설명도이다. 보일러용열교환기(13) 2차측에 공급되는 작동유체의 공급을 원활하게 하기 위하여 작동유체순환펌프(42)에 의해 보일러용열교환기(13) 2차측과 서지드럼(Surge Drum)(41) 사이를 작동유체가 순환하도록 관으로 연결하고 서지드럼(Surge Drum)(41) 내부로 유입된 기체상태 작동유체는 압력조절밸브(14)를 통하여 유출되도록 관으로 연결하고, 작동유체량조절밸브(19)를 지나온 액체상태 작동유체는 서지드럼(Surge Drum)(41)으로 유입되도록 관으로 연결한다. 작동유체는 보일러용열교환기(13) 2차측과 서지드럼(Surge Drum)(41) 사이를 순환하면서 보일러용열교환기(13) 1차측과 열교환을 잘 하여 빨리 증기상태로 변한다. 즉 보일러기능을 보강한 것이다. 나머지 작동원리는 도1에서 설명한 바와 같다.4 is an explanatory diagram of a transformer cooling device to which a surge drum is added. In order to facilitate the supply of the working fluid supplied to the secondary side of the boiler heat exchanger (13), between the secondary side of the boiler heat exchanger (13) and the surge drum (41) by the operating fluid circulation pump (42). Connect the working fluid to the pipe to circulate, and the gaseous working fluid introduced into the surge drum 41 is connected to the pipe so that the working fluid flows out through the pressure regulating valve 14, and the working fluid flow control valve 19 is connected. Passing the liquid working fluid is connected to the pipe to enter the surge drum (Surge Drum) (41). The working fluid circulates between the secondary side of the boiler heat exchanger 13 and the surge drum 41, and exchanges heat well with the primary side of the boiler heat exchanger 13 to quickly change into a vapor state. In other words, the boiler function is reinforced. The remaining operation principle is as described in FIG.

도 5는 팽창기에 터빈이 설치된 사례 설명도이다. 팽창기(15)(미도시)는 넓은 공간을 형성하고 있으며 그 안에 터빈(51)을 두고 터빈 축에 발전기(또는 기계장치)(52)를 설치하여 기화된 작동유체의 흐름에 의해 에너지를 회수한다. 그림에서는 팽창기(15)를 터빈(51)으로 대체하여 도시하였다. 이 때 에너지 상실에 따라 작동유체의 일부가 액화될 경우 이를 순환회로에 투입하기 위하여 액분리기(53)를 터빈(51)에 이어 설치한다. 액체상태 작동유체는 액분리기(53)에서 작동유체탱크(17)로 유입되고 기체상태 작동유체는 응축기(16)로 유입된다. 나머지 원리는 도1과 도4에서 설명한 바와 같다.5 is a diagram illustrating a case where a turbine is installed in the expander. The expander 15 (not shown) forms a large space, and has a turbine 51 therein, and installs a generator (or a mechanism) 52 on the turbine shaft to recover energy by the flow of vaporized working fluid. . In the figure, the inflator 15 is replaced with the turbine 51. At this time, when a part of the working fluid is liquefied due to the energy loss, the liquid separator 53 is installed after the turbine 51 in order to inject it into the circulation circuit. The liquid working fluid flows into the working fluid tank 17 from the liquid separator 53 and the gas working fluid flows into the condenser 16. The remaining principles are the same as described with reference to FIGS. 1 and 4.

도 6은 기체작동유체순환관이 설치된 사례 설명도이다. 터빈(51)의 회전에 의해 기체상태 작동유체는 송풍되지만 순환회로가 없으며 응축기(16)에서 열교환이 잘 일어나지 않을 수 있다. 응축기(16) 끝부분에 액분리기(53)를 추가하고 액분리기(53)의 기체유출관과 터빈(51) 기체유체유입관 사이를 연결하는 기체작동유체순환관(61)을 추가하여 터빈(51), 액분리기(53), 응축기(16), 액분리기(53), 다시 터빈(51)으로 기체상태 작동유체가 순환하여 응축효과를 높이도록 한다. 나머지 원리는 도1, 도4, 도5에서 설명한 바와 같다.6 is a diagram illustrating a case where a gas working fluid circulation tube is installed. The gaseous working fluid is blown by the rotation of the turbine 51, but there is no circulation circuit and heat exchange in the condenser 16 may not occur. A liquid separator (53) is added to the end of the condenser (16), and a gas working fluid circulation tube (61) connecting the gas outlet pipe of the liquid separator (53) and the gas fluid inlet pipe of the turbine (51) is added to the turbine (51). ), The liquid separator 53, the condenser 16, the liquid separator 53, and the turbine 51 again circulate gaseous working fluid to increase the condensation effect. The remaining principles are the same as those described with reference to FIGS. 1, 4, and 5.

도 7은 보일러 내포형 방열기를 보일러용열교환기로 활용한 사례 설명도이다. 변압기방열기(71)의 내부에 보일러(72)의 공간을 형성하여 작동유체가 보일러(72)에 유입되어 끓을 수 있도록 하고, 냉각장치를 작동하지 않을 경우에는 변압기방열판(71) 외부 표면을 통하여 냉각장치 기능을 수행할 수 있다. 이 것으로 보일러용열교환기(13)를 대신할 수 있다.7 is a diagram illustrating an example in which a boiler-containing radiator is used as a heat exchanger for a boiler. A space of the boiler 72 is formed inside the transformer radiator 71 so that the working fluid flows into the boiler 72 and boils, and when the cooling device is not operated, cooling is performed through the outer surface of the transformer radiator 71. Device functions can be performed. This can replace the heat exchanger 13 for boilers.

도 8은 보일러 외포형 방열기를 보일러용열교환기로 활용한 사례 설명도이다. 변압기방열기(71)를 감싸도록 설치되는 보일러(72)와 이 보일러(72)를 감싸도록 순서대로 외부에 설치되는 단열재(81), 외함(82)으로 마감처리 한다. 이 것으로 보일러용열교환기(13)를 대신할 수 있다.8 is a diagram illustrating a case using a boiler envelope radiator as a heat exchanger for a boiler. Boiler 72 is installed to surround the transformer radiator 71 and the heat insulating material 81, the outer box 82 is installed in order to surround the boiler 72 is finished. This can replace the heat exchanger 13 for boilers.

도 9는 미응축기체압축기가 설치된 사례 설명도이다. 응축기(16)의 성능이 모자랄 경우 일부 미응축기체가 존재할 수 있고 응축기(16)를 통과한 미응축기체는 미응축기체압축기(91)에서 압축된 후 액체상태로 변하고 작동유체공급펌프(18)를 통하여 보일러용열교환기(13)로 유입된다. 다른 원리는 도1에서 설명한 바와 같다.9 is a diagram illustrating a case where a non-condensing gas compressor is installed. If the performance of the condenser 16 is insufficient, some uncondensed gas may be present, and the uncondensed gas that has passed through the condenser 16 is compressed in the uncondensed gas compressor 91 to become a liquid state, and the working fluid supply pump 18 Through the heat exchanger for the boiler 13 is introduced. The other principle is as described in FIG.

변압기의 냉각에 냉동사이클을 적용할 수도 있지만 이 경우 압축기는 반드시 필요하며 응축기(16)는 증발기에서 취득한 열과 압축기가 한 일에 해당하는 열을 추가하여 제거해야 하므로 응축기가 커지는 단점이 있었다. 변압기의 유지온도가 상온보다 높아도 문제가 되지 않은 점을 착안하여 역냉동사이클인 발전랭킨사이클을 적용하면 응축기(16)의 규모를 줄일 수 있어 설치공간이 작아지고, 팽창기(15) 에서 에너지도 회수 할 수 있는 장점이 있다. 큰 규모의 압축기가 필요치 않으므로 에너지 사용량도 줄일 수 있다.Although a refrigeration cycle may be applied to the cooling of the transformer, a compressor is necessary in this case, and the condenser 16 has a disadvantage in that the condenser becomes large because the heat obtained from the evaporator must be removed by adding heat corresponding to the work done by the compressor. Taking into consideration that it is not a problem even if the maintenance temperature of the transformer is higher than room temperature, the application of the power generation Rankine cycle, which is a reverse refrigeration cycle, can reduce the size of the condenser 16, thereby reducing the installation space and recovering energy from the expander 15. There is an advantage to this. Energy consumption is also reduced because no large compressor is required.
