Title:
エレベータ駆動システムの電源変動の管理
Document Type and Number:
Japanese Patent JP5122570
Kind Code:
B2
Abstract:
A device (22) manages power source variations in an elevator system. The device includes a transformer (60) having a primary (62) and a secondary (64). An input of the elevator system is connected to the secondary (64). Tap switches (66a, 66b, 66c, 66d) are connected to the transformer (60) such that each tap switch is connected to a tap point (68a, 68b, 68c, 68d) on the transformer (60). A controller (54) operates the tap switches (66a, 66b, 66c, 66d) based on a sensed power source output to provide power on the secondary (64) within a tolerance band of the elevator system.
