Abstract: 본 발명은 무선 전력전송 장치의 교류 전원장치와 급전선로를 잇는 연장선을 내측선과 외측선의 일체형으로 구성하여 인덕턴스가 제로인 무유도 전력선을 구현하고, 연장선의 정중앙부에 과열 감지선을 삽입하여 유도 가열에 의한 연장선의 가열에 대해 신뢰성이 있는 감지를 달성하는 기술이다. 특히, 본 발명은 내측선을 외측선의 정중앙에 삽입하는 형태로 구성하여 내측선과 외측선 각각으로부터 발생하는 자속이 서로 상쇄되어 외측선과 내측선으로부터 인덕턴스가 제로 상태가 되도록 하고, 내측선의 중앙부에 과열 감지선을 일체형으로 삽입하여 내측선과 외측선으로부터 발생하는 자속으로부터 과열 감지선은 유도 가열이 일어나지 않아 내측선에 대한 신뢰성 있는 열감지를 수행하도록 하는 기술에 관한 것이다. 본 발명에 따르면 내측선과 과열 감지선이 상호 밀착되어 있기 때문에 발열감지의 신뢰성이 매우 높은 장점이 있다.

Abstract: The present invention relates to a protection circuit for wireless power transfer device which supplies the power to a movable body by the alternating electromotive force applied to a pickup coil and relates to the pickup coil, installed on the movable body, in which the alternating electromotive force is applied by the magnetic flux generated from an induced current from a wireless power transfer device which supplies power wireless to the movable body moving along a track. Generally, the problem of the power transfer device is that there is no way to block an inverter on a first side when there is an error of the overvoltage, overcurrent, and overheating since without an additional communications device, it is not possible to recognize the state of a device on the second side. Another problem is that a distance between the device on the second side comprising a pickup coil, a resonant circuit, and a rectifying section on which the inverter on the first side and the movable body are installed is too large. To solve the problems, by recognizing an error occurred in the device on the second side, a protective circuit on the second side is provided which can block inputs of a rectifier by cutting the two ends of the pickup coil.
Abstract translation: 本发明涉及一种用于无线电力传送装置的保护电路，其通过施加到拾取线圈的交变电动势将动力提供给可移动体，并且涉及安装在可移动体上的拾取线圈，其中交变电动势 由从无线功率传输装置产生的感应电流产生的磁通量施加到沿轨道移动的可移动体。 一般来说，电力传输装置的问题在于，由于没有附加的通信装置，当存在过电压，过电流和过热的误差时，无法阻止第一侧的逆变器，所以不可能识别出 第二面设备状态。 另一个问题是，包括拾波线圈，谐振电路的第二侧的装置与安装有第一侧的逆变器和可移动体的整流部分之间的距离太大。 为了解决上述问题，通过识别在第二侧的装置中发生的错误，提供了第二侧的保护电路，其可以通过切割拾取线圈的两端来阻断整流器的输入。
