Abstract

The invention relates to an overload protection device used in a ground switch operating device. The overload protection device comprises a first main shaft having a shaft rod and a shaft cap at one end of the shaft rod; a first gear sleeving the shaft rod and arranged adjacent to the shaft cap; a second gear sleeving the shaft rod and disposed adjacent to the first gear, wherein the first gear defines at least one first groove in a surface facing the second gear, and the second gear defines at least one second groove in a surface facing the first gear; an elastic biasing mechanism for biasing the second gear axially toward the first gear; a first rolling member configured to be received in the first and second grooves in order to transfer power between the first and second gears and configured to slide from the first groove and / or the second groove when overload force is present; and a stopper for limiting the axial displacement of the elastic biasing mechanism. The invention also relates to an operation device including a ground switch of the overload protection device, and a ground switch.

Description

technical field [0001] The invention relates to the technical field of grounding switches, in particular to grounding switches used in switch cabinets. The invention also relates to an operating device for an earthing switch and an overload protection device used in the operating device for the earthing switch. Background technique [0002] The existing earthing switch operating device includes a housing, a micro switch arranged on the housing, an output mechanism with a hexagonal operating rod, a motor and a manual electric switching mechanism. Wherein, the motor is directly connected with the manual electric switching mechanism, so that the power is transmitted from the output shaft of the motor to the manual electric switching mechanism through a transmission mechanism such as a worm gear, so as to be transmitted to the output mechanism through the manual electric mechanism, so as to realize the electric mode to switch the microswitch between closing and opening. Althou...
