Description

Technical Field

[0001] The utility model relates to the technical field of isolating switches, in particular to an operating mechanism for isolating switches. Background Art

[0002] An operating mechanism for an isolating switch realizes the opening and closing action of the switch by rotating an operating handle. The existing operating mechanism generally realizes 90-degree rotation transmission through bevel gears. Although the spring has a process from compression to release during operation, since the transmission is only realized through the meshing of gears, the output angular velocity of the mechanism is completely synchronized with the angular velocity of the operator's rotating handle, resulting in a slow opening and closing speed of the switch, which is extremely disadvantageous when disconnecting current, and brings certain hidden dangers to the connection and disconnection of the isolating switch.
