向电梯轿厢供电的供电装置
摘要：
一种供电装置(10)，以非接触方式将电力供给于电梯(1)的轿厢(2)。该供电装置(10)具有供电线(11)、高频电源(12)、铁芯(131)、线圈(132)和磁性体(14)。供电线(11)架设在升降井(3)内轿厢(2)进行移动的范围的整个长度上。高频电源(12)将高频电流供给于供电线(11)。铁芯(131)安装在轿厢(2)上，具有内侧以非接触方式配置有供电线(11)的槽(134)。线圈(132)以与供电线(11)交叉的方向为中心卷绕在铁芯(131)上。磁性体(14)沿升降井(3)与各楼层对应地配置，在轿厢(2)停靠在各楼层的状态下以非接触方式与铁芯(131)相对，并与铁芯(131)一起构成磁性回路。
摘要（英）：

A power supply unit (10) supplies the power to a car (2) of an elevator (1) in a non-contact mode. The power supply unit (10) has power supply lines (11), high frequency power supply (12), iron core (131), coil (132) and magnetic substance (14). The power supply lines (11) are spanned on the whole length of the car (2) moving in the shaft (3). The high frequency power supply (12) supplies the high frequency current to the power supply lines (11). The iron core (131) is installed on the car (2) and has a groove (134) configured with the internal power supply lines (11) by a non-contact mode. The coil (132) is wound on the iron core (131) taking the direction crossing with the power supply lines (11) as center. The magnetic substance (14) is correspondingly configured with each floor along the shaft (3) and is opposite to the iron core (131) by a non-contact mode in the state of the car (2) stopping at each floor and composes a magnetic circuit with the iron core (131).
