Fault current limiting smart superconducting cable winding structure that also performs current limiting function, and smart superconducting cable winding structure used for dual use of transmission and distribution cable and reactor type current limiter can be produced by simple operation of inserting metal core into the superconducting cable drum itself. The present invention relates to a superconducting cable winding structure-based current limiter combined power transmission device capable of independently controlling the cooling of the superconducting cable winding structure that generates heat according to the inflow of fault current.
초전도 케이블은 전력손실없이 대용량의 전력수송이 가능하므로, 송배전 케이블로의 활용을 위한 연구개발이 활발하게 이루어지고 있다. 이와 같은 초전도 케이블은 기본적으로 포머, 통전층, 차폐층으로 구성된 동축 케이블로서, 포머와 통전층은 전기적으로 연결되어 있다. 초전도 케이블의 정상운전 시 통전층에 흐르는 전류는 완벽하게 차폐층에 유도되어 케이블 외부로 자기장이 누설되지 않는다. 그러나 계통 사고에 따라 통전층의 임계전류보다 큰 고장전류가 흐르게 되면, "Quench"가 발생하면서 통전층의 저항이 급격하게 증가하여 상대적으로 저항이 낮은 구리 포머로 전류가 우회하여 통전층을 보호하게 된다. 그리고 고장전류 유입시 전자기 유도에 의해 전류가 발생하는 차폐층에는 "Quench"의 발생으로 통전층보다 훨씬 적은 전류만이 유도된다. 즉 차폐층의 "Quench"로 인하여 통전층 전류를 완벽하게 유도시키지 못하게 됨으로써 자기장이 초전도 케이블 외부로 누설되면서 케이블 자체의 임피던스가 증가하게 된다.Superconducting cable is capable of large-capacity power transmission without loss of power, so research and development for the use as a transmission and distribution cable is actively being made. Such a superconducting cable is basically a coaxial cable composed of a former, a conductive layer, and a shielding layer, and the former and the conductive layer are electrically connected to each other. During normal operation of the superconducting cable, the current flowing through the conducting layer is completely induced in the shielding layer so that no magnetic field leaks out of the cable. However, if a fault current larger than the critical current of the conductive layer flows due to the system accident, "Quench" occurs and the resistance of the conductive layer increases rapidly, so that the current is bypassed by a relatively low-resistance copper former to protect the conductive layer. do. In addition, in the shielding layer where current is generated by electromagnetic induction when a fault current is introduced, much less current is induced than the conducting layer due to the generation of "Quench". That is, the "Quench" of the shielding layer does not completely induce the conduction layer current, so that the magnetic field leaks out of the superconducting cable, thereby increasing the impedance of the cable itself.
한편 한류 기능을 갖는 초전도 케이블에는 저항형 한류 케이블과 유도형 한류 케이블이 있는데, 저항형 한류 케이블은 고장전류가 케이블로 유입될 시 통전층의 "Quench"로 인한 통전층 자체의 저항 성분으로 임피던스를 발생시켜 고장전류를 제한하게 되는 것이고, 유도형 한류 케이블은 고장전류가 케이블로 유입될 시 차폐층의 "Quench"에 따라 외부로 방출되는 자기장이 케이블 외부의 철심에 집속되어 쇄교되는 자속을 통해 발생되는 유도성 임피던스로 고장전류를 제한하게 되는 것이다. 이와 같은 유도형 한류 케이블과 관련한 기술로는 본 출원인에 의해 출원된 대한민국 공개특허공보 공개번호 제10-2012-0032961호 "유도형 초전도 한류 케이블"(특허문헌 1)이 있다.On the other hand, superconducting cables with current-limiting functions include resistance-type current-limiting cables and inductive-type current-limiting cables. Resistance-type current-limiting cables are impedance components of the current-carrying layer itself due to "Quench" in the current-carrying layer when a fault current flows into the cable. Induced current-limiting cable is generated by magnetic flux emitted to the outside according to the "Quench" of the shielding layer when the fault current flows into the cable, and is concentrated through the magnetic flux that is chained to the iron core outside the cable. This will limit the fault current to the inductive impedance. As a technique related to such an inductive current-limiting cable, there is a Korean Patent Application Publication No. 10-2012-0032961 filed by the present applicant "Induction-type superconducting current-limiting cable" (Patent Document 1).
여기서 고장전류를 통전층이 직접 감당하는 저항형 한류 케이블의 경우 고장전류의 크기의 제곱에 비례하는 통전층의 발열이 발생하고, 냉매인 액체질소가 발열에 의해 기화되는 것을 막기 위하여 질소의 운전압력을 상향 조절해야 하며, 계통 사고에 따른 고장전류 유입 후 발열에 대한 충분한 열적 회복시간이 필요한 단점이 있다. 또한 초전도 케이블이 배치되는 계통의 상황에 적합한 한류 저항을 발생시키기 위하여 초전도 선재의 사양, 포머의 단면적, 적용 개소의 케이블 길이를 맞춤식으로 설계해야 하고, 절연구조 설계도 필수적으로 요구되는 번거로움도 있다. Here, in the case of a resistive current-limiting cable that directly handles the fault current by the conducting layer, heat generation of the conducting layer in proportion to the square of the magnitude of the fault current occurs, and operating pressure of nitrogen to prevent the liquid nitrogen, which is a refrigerant, from vaporizing due to the heat generation. It is necessary to adjust upward, and sufficient heat recovery time for heat generation after inflow of fault current due to system accident is required. In addition, in order to generate a current-limiting resistance suitable for the situation in which the superconducting cable is arranged, the specification of the superconducting wire, the cross-sectional area of the former, and the cable length of the application location must be customized, and the design of the insulating structure is also required.
이에 반하여 유도형 한류 케이블의 경우 케이블 바깥의 철심에 쇄교되는 자속을 통해 유도성 임피던스 성분으로 고장전류를 제한하는 것임에 따라 케이블 외부에서 발열이 발생하는 한편, 고장전류를 통전층과 포머가 같이 감당하는 동시에 대부분의 사고전류가 포머를 통해 흘러 상대적으로 적은 발열이 발생됨으로써 질소의 운전압력 상향 조절할 필요가 없고, 제한된 크기의 공간 내에 설치할 수 있으며, 초전도 케이블과 상전도 케이블을 연계하는 것도 가능한 이점이 있다.
