Description

정지형 히터트리거타입 고온 초전도 전원장치{HEATER TRIGGERED TYPE HIGH TEMPERATURE SUPERCONDUCTING POWER SUPPLY}HEATER TRIGGERED TYPE HIGH TEMPERATURE SUPERCONDUCTING POWER SUPPLY}

본 발명은 초전도부하에 전원을 공급하는 장치에 관한 것으로서, 더욱 상세하게는 히터트리거형태의 초전도스위치를 사용하는 정지형 히터트리거타입의 고온 초전도 전원장치에 관한 것이다.The present invention relates to a device for supplying power to a superconducting load, and more particularly, to a high temperature superconducting power supply of a stationary heater trigger type using a superconductor switch of a heater trigger type.

대표적인 초전도부하는 현재 의료분야에서 사용되어지는 핵자기공명영상장치(MRI), 에너지 저장장치인 SMES(Superconducting Magnetic Energy Storage), 회전기기인 초전도 전동기와 초전도 발전기 등이 있으며, 이들은 공통적으로 고자장을 얻기 위하여 초전도 자석을 이용하고 있으며 외부의 별도 전원 장치에 의하여 전원을 공급받는다. 외부에서 전원을 공급받을 시에는 상전도 전원장치를 주로 사용함으로서 전원장치의 크기가 크며 더구나 저온조 내부에 설치되는 초전도 자석과 연결시 상전도체와 초전도체간의 접합이 존재하게 되고 이로 인하여 전기저항이 발생하며 이 전기저항에 의하여 발열을 하게 된다. 이로 인하여 열손실이 발생할 뿐 만 아니라 시스템의 안정을 해치는 결과를 초래한다.Representative superconducting loads include nuclear magnetic resonance imaging (MRI), which is currently used in the medical field, superconducting magnetic energy storage (SMES), and superconducting motors and superconducting generators, which are rotating devices. Superconducting magnets are used to obtain power and are supplied by an external power supply. When the power is supplied from the outside, the phase conduction power supply is mainly used, and the size of the power supply is large. Moreover, the connection between the phase conductor and the superconductor exists when connecting with the superconducting magnet installed inside the low temperature tank, which causes electrical resistance. And it generates heat by this electric resistance. This not only results in heat loss, but also results in compromised system stability.

본 분야에서 이를 해소하기 위하여 초전도 부하에 전원을 공급하는 전원장치를 초전도 전원장치로 대치하고자 하는 연구 개발이 지속되고 있으며 이러한 노력의 결과로 회전자속형 초전도 전류발생장치와 초전도 부하를 초전도 선재로 연결하는 시스템이 본 발명자들에 의하여 개발된 적이 있다.In order to solve this problem, research and development to replace the superconducting power supply with the superconducting power supply has been continued. As a result of this effort, the superconducting current type and the superconducting load are connected to the superconducting wire. System has been developed by the inventors.

그러나 이러한 초전도 전류발생장치는 저온 초전도체를 사용하기 때문에 냉매로 고가의 액체 헬륨을 필요로 하게 된다. 따라서 냉각시스템의 설계 및 제작이 어렵고 경제성이 없다.However, since the superconducting current generator uses a low temperature superconductor, an expensive liquid helium is required as the refrigerant. Therefore, the design and manufacture of the cooling system is difficult and economical.

본 분야에서는 고온 초전도체의 개발을 하고자 노력한 결과 초전도체의 저항이 없어지는 온도가 점진적으로 증가하는 초전도 물질이 개발되어 오던 중 1987년 미국의 휴스턴 대학에서 액체 질소의 온도(77K) 이상인 92K에서 초전도 현상이 발생하는 YBaCuO가 발견된 것을 필두로 BiSrCaCuO와 TiBaCaCuOr 계열의 산화물 초전도체가 발견됨으로서 냉매로 액체 질소를 사용하는 경제성이 우수한 초전도 전원장치를 실현할 수가 있는 토대가 마련되었으나 고온초전도체를 초전도 전원장치에 활용하기 위하여는 전류 펌핑을 위한 스위칭 기술이 개발되지 않아 아직까지 고온초전도체를 이용한 초전도 전원장치가 개발되지 못하고 있는 실정이다.In this field, as a result of the development of high temperature superconductor, superconducting materials with gradually increasing temperature disappearing of superconductor have been developed. In 1987, the superconducting phenomenon occurred at 92K, which is higher than liquid nitrogen (77K), at the University of Houston, USA. The discovery of BiSrCaCuO and TiBaCaCuOr series oxide superconductors, which led to the discovery of the generated YBaCuO, provided the foundation for realizing a superconducting power supply with excellent economical efficiency using liquid nitrogen as a refrigerant, but to utilize the high temperature superconductor in superconducting power supplies. Since the switching technology for current pumping has not been developed, a superconducting power supply using a high temperature superconductor has not been developed yet.

고온초전도 전원 장치의 핵심요소는 초전도 스위치이다. 초전도스위치는 초전도 상태를 상전도 상태로 전이하는 역할을 하여 초전도회로의 개폐를 용이하게 하는 장치이다. 초전도스위치의 형태를 살펴보면 회전자에서 발생하는 임계밀도 이상의 자속을 투과하여 초전도회로를 온/오프하는 회전형과 초전도체에 히터를 권선하여 전류를 인가함으로서 초전도회로의 상전이를 발생시키는 정지형이 있다.A key element of the high temperature superconducting power supply is the superconducting switch. The superconducting switch is a device that facilitates the opening and closing of the superconducting circuit by serving to transfer the superconducting state to the phase conducting state. Looking at the shape of the superconducting switch, there are a rotating type that transmits a magnetic flux above a critical density generated by the rotor to turn on / off the superconducting circuit and a stationary type that generates a phase transition of the superconducting circuit by applying a current by winding a heater to the superconductor.

본 발명은 저항이 없는 초전도체로 구성된 초전도부하에 전원을 공급함에 있어서 전원공급장치와 초전도부하 사이의 접합부에서 주울열 발생 등으로 인한 손실을 줄이고, 초전도부하와 같은 극저온 환경에서 동작하는 초전도 전원장치에 고온초전도체를 사용함으로서 액체 질소를 냉매로 사용할 수 있어 경제적이고, 또한 회전부가 없어 그 구성이 간단한 정지형 히터트리거타입 초전도전원장치를 제공하기 위한 것이다.The present invention reduces the loss due to Joule heat generation at the junction between the power supply and the superconducting load in supplying power to the superconducting load consisting of a superconductor without resistance, and to a superconducting power supply that operates in a cryogenic environment such as a superconducting load. It is to provide a stationary heater trigger type superconducting power supply device which is economical since the use of a high temperature superconductor can be used as a refrigerant and is simple in its structure without a rotating part.

상기한 목적을 달성하기 위하여 본 발명에 따른 정지형 히터트리거타입 고온초전도 전원장치는 자속을 공급하는 전자석과 초전도 스위치기능을 수행하기 위하여 초전도체에 권선된 두 개의 히터와, 전자석에서 발생한 자속을 초전도 코일에 쇄교시키기 위하여 규소강판 등으로 제작된 철심과 두 개의 히터를 제어하고 전자석에 공급되는 전원의 제어 등을 목적으로 하여 초전도 전원장치를 제어하는 콘트롤러부와 초전도 전원장치에서 발생한 전류를 공급받아 자계를 발생하는 초전도부하로 구성된다.In order to achieve the above object, the stationary heater trigger type high temperature superconducting power supply according to the present invention includes an electromagnet for supplying magnetic flux and two heaters wound on the superconductor to perform a superconducting switch function, and magnetic flux generated from the electromagnet to the superconducting coil. In order to control the iron core and two heaters made of silicon steel, etc., to control the power supply to the electromagnet, the controller unit controlling the superconducting power supply and the electric current generated from the superconducting power supply are generated. It consists of superconducting load.

본 발명의 구성은 도 1의 정지형 히터트리거타입 고온초전도 전원장치의 구조도에 나타난 바와 같이 규소강판 등으로 사각형의 자계회로(1)를 구성하고 사각형의 한 변, 즉 한쪽 레그(1차측)에는 자계발생부(2)로 외부 전원을 공급받아 자속을 발생시키는 코일이 권선되어 있으며, 타 측 레그(2차측)에는 고온 초전도체로 된 초전도코일(3)을 권선하였다. 초전도코일 양단은 초전도부하(6)와 연결되어 초전도코일에서 발생된 전류를 공급받아 자계를 발생하게 된다. 초전도코일의 일정부위에 극저온용 니크롬선을 권선한 제 1히터트리거스위치(4)가 부착되고 초전도코일과 초전도부하를 연결하는 양선 사이에 두 개의 초전도 폐루프가 형성되도록 고온초전도체로 된 단락선(7)을 연결하고 이 단락선(7)중간부위에 제 2히터트리거스위치(5)를 설치한다.As shown in the structural diagram of the stationary heater trigger type high temperature superconducting power supply device of FIG. 1, the configuration of the present invention comprises a rectangular magnetic circuit 1 made of silicon steel or the like, and the magnetic field is formed on one side of the square, that is, one leg (primary side). Coils are generated to generate magnetic flux by receiving external power from the generator 2, and a superconducting coil 3 made of a high temperature superconductor is wound on the other leg (secondary side). Both ends of the superconducting coil are connected to the superconducting load 6 to receive a current generated from the superconducting coil to generate a magnetic field. A short-circuit wire made of a high temperature superconductor such that a first heater trigger switch 4 having a cryogenic nichrome wire wound around a portion of the superconducting coil is attached, and two superconducting closed loops are formed between the two lines connecting the superconducting coil and the superconducting load. 7) and install the second heater trigger switch (5) in the middle of the short circuit (7).

상기한 구성의 정지형 고온초전도 전원장치의 동작과정을 도 1, 도 2 및 도3을 중심으로 상세히 설명한다.An operation process of the stationary high temperature superconducting power supply having the above configuration will be described in detail with reference to FIGS. 1, 2, and 3.

먼저 본 발명의 전류 펌핑 원리를 설명하고자 한다.First, the present pumping principle of the present invention will be described.

용이한 설명을 위하여 상기 도 1의 구성을 도 2와 같이 간략화하여 표시하였다.For ease of explanation, the configuration of FIG. 1 is simplified and displayed as shown in FIG. 2.

도 3에서와 같이 먼저 변압기 형태의 1차측 철심에 권선된 전자석에 외부전원을 인가하여 자속을 발생시킨다. 발생된 자속은 철심에 의해 2차측의 초전도코일과 쇄교하여 초전도 코일에 전류를 발생시킨다. 발생된 전류는 초전도부하를 통하여 흐른다고 가정하고(이하에서는 루프 1이라 한다)(S1), 제어부의 제어에 의하여 초전도코일(3)내의 히터1(이하에서는 제 1히터 트리거스위치)(4)에 전류를 공급하면 가열된 부위는 상전도체가 되어 루프 1에는 저항이 발생하게 되고 전류I는 초전도부하와 초전도 단락선(5)을 통하여 흐르게 된다(이하에서는 루프 2라 한다)(S2)As shown in FIG. 3, an external power source is applied to an electromagnet wound on a primary iron core of a transformer to generate magnetic flux. The generated magnetic flux is connected with the superconducting coil on the secondary side by the iron core to generate a current in the superconducting coil. It is assumed that the generated current flows through the superconducting load (hereinafter referred to as loop 1) (S1), and to the heater 1 (hereinafter, the first heater trigger switch) 4 in the superconducting coil 3 under the control of the controller. When the current is supplied, the heated portion becomes a phase conductor and resistance occurs in loop 1, and current I flows through the superconducting load and the superconducting short circuit 5 (hereinafter referred to as loop 2) (S2)

그 다음 자계발생부(2)를 구동시켜 루프 1에 자속을 인가하고(S3), 제 1히터트리거스위치(4)에 공급되는 전원을 차단하면(S4), 제 1히터트리거스위치(4)는 냉매에 의하여 냉각되어 다시 초전도 상태로 되고, 다음으로 전자석에 공급하는 전원을 차단하면 루프 1내에 자속변화가 일어나게 되어 결국 -dφ/dt 만큼의 유기 기전력이 초전도코일(3)에 유기된다. 이 유기 기전력에 의하여 전류가 발생되며 인가한 총자속에 의해 증가한 전류만큼(ΔI) 루프 1에 발생한다. 이 때, 초기전류는 루프 2에 그대로 흐르게 된다.Then, when the magnetic field generator 2 is driven to apply magnetic flux to the loop 1 (S3) and the power supplied to the first heater trigger switch 4 is cut off (S4), the first heater trigger switch 4 When the refrigerant is cooled by the refrigerant to be in a superconducting state again, when the power supply to the electromagnet is cut off, a magnetic flux change occurs in the loop 1, and finally, the organic electromotive force of -d? / Dt is induced in the superconducting coil 3. The current is generated by this induced electromotive force and occurs in loop 1 by the current increased by the applied total flux (ΔI). At this time, the initial current flows in the loop 2 as it is.

다음으로 단락선(7)에 감겨진 히터(이하에서는 제 2히터트리거스위치 라 함)(5)에 전원을 공급하면 단락선의 가열부위는 상전도체가 되어 저항이 발생하고루프 2에 흐르던 전류(I)는 루프 1로 흐르게 된다.Next, when power is supplied to the heater (hereinafter referred to as the second heater trigger switch) 5 wound on the short circuit 7, the heating portion of the short circuit becomes a phase conductor, a resistance is generated, and the current flowing through the loop 2 (I ) Flows to loop 1.

루프 1에는 루프 2에서 전이된 전류(I)에 증가한 전류(ΔI)가 더하여져 즉 I+ΔI가 흐르게 되어 전류 펌핑이 이루어지며(S5), 이후 제 1히터트리거스위치(4)에 전원을 인가하여 가열된 부위를 상전도로 전환시키고, 제 2히터트리거(7)에 전원를 차단하면 단락선이 초전도 상태로 회복되어 전류는 루프 2로 전이되어 흐르게된다(S6). 이는 저항이 없는 초전도 폐루프에서 전류의 흐름을 나타낸 것이며, 전류는 항상 저항이 작은 쪽으로 흐른다는 것을 보여주고 있다.In loop 1, an increased current ΔI is added to the current I transferred in loop 2, that is, I + ΔI flows to perform current pumping (S5), and then power is supplied to the first heater trigger switch 4. When the heated portion is switched to the phase conduction and the power is cut off to the second heater trigger 7, the short circuit is restored to the superconducting state, and the current is transferred to the loop 2 and flows (S6). This shows the flow of current in a superconducting closed loop without resistance, which shows that the current always flows in the smaller direction.

상기한 일련의 과정을 반복을 통하여 초전도부하에 공급되는 전류를 증가시킬 수 있으며 결국 전류는 계단형상으로 증가하게 될 것이다.By repeating the above series of steps, the current supplied to the superconducting load can be increased and eventually the current will increase stepwise.
