Title:
REMOTELY-CONTROLLED ROTARY ISOLATOR SWITCH
Document Type and Number:
WIPO Patent Application WO/2024/051714
Kind Code:
A1
Abstract:
A remotely-controlled rotary isolator switch, comprising an operating device (1) and a switch body (2). The switch body (2) comprises at least one switch unit, and the switch unit comprises a moving contact assembly (225) and a static contact. The operating device (1) is transmittingly connected to the moving contact assembly (225) of the switch unit, and drives the moving contact assembly (225) to rotate so as to be in contact with or separated from the static contact, thereby achieving connection or disconnection of a circuit. The operating device (1) comprises an operating shaft (1131), a real-time energy storage mechanism, a delayed energy storage mechanism, a locking mechanism, and a trip mechanism. The locking mechanism comprises a locking member (122). The trip mechanism comprises a trip unit (134). The trip unit (134) acts after receiving a trip signal, and drives the locking member (122) to release the locking of the delayed energy storage mechanism, and the delayed energy storage mechanism releases energy so as to drive the operating shaft (1131) to rotate toward an open position, so that the remotely-controlled rotary isolator switch is switched to an open state. The remotely-controlled rotary isolator switch has good reliability.
