온라인 전기자동차의 자기장 차폐장치{Magenetic Field Cancellation apparatus for OLEV}Magnetic Field Shielding Device for Online Electric Vehicles {Magenetic Field Cancellation apparatus for OLEV}

본 발명은 온라인 전기자동차의 자기장 차폐장치에 관한 것으로, 특히 급전장치 및 차폐장치에서 발생하는 불요 자기장에 대하여 차폐를 위해, 집전부의 집전장치와, 급전선로의 급전장치를 동시에 차폐하는 온라인 전기자동차 급전부 및 집전부의 자기장 차폐장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic field shield of an on-line electric vehicle, and in particular, an on-line electric vehicle that simultaneously shields a current collector of a current collector and a power feeder of a feeder line for shielding against unnecessary magnetic fields generated by the power supply device and the shielding device. The magnetic field shielding device of the feeder and the collector.

환경오염 문제를 유발하는 화석연료를 바탕으로 동작하는 기존의 자동차를 대체하기 위해 개발중인 대체 에너지 자동차 중, 배터리 모듈을 탑재한 전기 자동차는 배터리 용량의 한계로 인하여 장거리 주행이 어려우며, 또한 배터리의 충전을 위해 소정시간동안 전력공급수단에 연결하여 기다려야한다는 단점이 있다. 뿐만 아니라, 1회 충전으로 주행할 수 있는 거리가 제한적이다.Among alternative energy vehicles that are being developed to replace existing vehicles operating on fossil fuels that cause environmental pollution problems, electric vehicles equipped with battery modules are difficult to drive over long distances due to the limitation of battery capacity. There is a drawback to wait for a predetermined time by connecting to the power supply means. In addition, the distance that can be driven on a single charge is limited.

이러한 단점을 극복하기 위해, 배터리의 용량을 늘리고 충전 시스템의 효율을 높이는 기술이 개발되었으나, 차량 무게의 증가로 효율이 떨어지고, 차량 단가가 상승하며, 배터리의 수명이 짧아지는 다른 문제점이 발생하였다.In order to overcome these disadvantages, a technology for increasing the capacity of the battery and increasing the efficiency of the charging system has been developed, but other problems occur that increase efficiency of the vehicle, decrease the efficiency, increase the unit cost, and shorten the battery life.

이에 따라, 전술한 배터리 모듈 탑재형 전기자동차의 개선된 형태로서, 도로 밑에 급전장치를 설치하고 이를 통한 자기유도방식으로 배터리를 충전하는 온라인 전기자동차가 제안되었다. 이러한 자기유도방식 전기자동차는 급전장치로부터 전력공급이 중단되는 경우에는 탑재된 배터리의 충전 전력으로 구동되는 장점이 있다.Accordingly, as an improved form of the aforementioned battery module-mounted electric vehicle, an on-line electric vehicle has been proposed to install a power feeding device under the road and charge the battery in a self-induction manner. Such a self-induction electric vehicle has an advantage of being driven by the charging power of the mounted battery when the power supply is interrupted from the power feeding device.

전술한 전기자동차의 급전부 및 집전부에서는 필연적으로 불요 자기장이 발생하게 되며, 이에 대한 차폐 기술로서 기존에 제안된 MFCW(Magenetic Field Cancellation Wiring)은 모노타입(mono type) 집전장치에 대한 자기장 차폐 기술이다. 이는 자기장 형성 분포가 Horizontal Direction으로 형성되어 집전장치 양 끝단에 구리코일(copper coil)로 와이어링(Wiring)함으로서 형성된 불요 자기장을 손쉽게 Cancelling 할 수 있다는 장점이 있다. 그러나, 듀얼타입(dual type) 집전장치 즉, 출력 효율을 향상시킨 집전장치는 자기장 형성 분포가 Vertical Direction으로 형성되어 종래의 기술을 적용할 경우 전혀 자기장을 상쇄시키지 못하고 오히려 배가시키는 경우가 많다는 문제점이 있었다.An unnecessary magnetic field is inevitably generated at the feeder and the collector of the electric vehicle described above. As a shielding technology, the previously proposed MFCW (Magenetic Field Cancellation Wiring) is a magnetic shielding technology for a mono type current collector. to be. This has the advantage that the magnetic field formation distribution is formed in a horizontal direction so that the unwanted magnetic field formed by wiring with copper coils at both ends of the current collector can be easily canceled. However, the dual type current collector, that is, the current collector having improved output efficiency, has a problem in that the magnetic field formation distribution is formed in the vertical direction so that the magnetic field is not canceled at all, but rather doubled when the conventional technique is applied. there was.

본 발명은 전술한 문제점을 해결하기 위해 안출된 것으로, 출력 효율을 향상시킨 듀얼타입(dual type) 집전장치에서, Vertical Direction으로 형성되는 자기장 을 보다 효율적으로 차폐하는 온라인 전기자동차 급전부 및 집전부의 자기장 차폐장치를 제공하는 데 그 목적이 있다. SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and in the dual type current collector having improved output efficiency, an on-line electric vehicle power supply unit and a current collector unit that effectively shield a magnetic field formed in a vertical direction The object is to provide a magnetic shield.
