Title:
SWITCH, GAS-INSULATED SWITCHGEAR, AND SWITCH CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2022/009264
Kind Code:
A1
Abstract:
This switch (20) comprises: a fixed contact (32); a movable contact (31); motors (22, 49) that drive the movable contact (31) via a drive mechanism (30) that converts a rotary motion into a linear motion; and drive control devices (21, 47) that drive and control the motors (22, 49). The drive control devices (21, 47) control the rotation speed of the motors (22, 49) during the open operation of the switch (20) such that the moving speed of the movable contact (31) in a part of the entire movement range of the movable contact (31) is lower than the moving speed of the movable contact (31) when the switch (20) is turned on. The part of the entire movement range includes a breaking point where the arc current is extinguished.
