The utility model provides a grounding switch operating mechanism, a locking electromagnet module and a locking electromagnet device, and belongs to the technical field of grounding switch safety locking. The grounding switch locking electromagnet module comprises a locking electromagnet coil circuit, a locking electromagnet coil is arranged on the locking electromagnet coil circuit in series, a divider resistor is further arranged on the locking electromagnet coil circuit in series, and the divider resistor is provided with a control switch in parallel. According to the grounding switch locking electromagnet module, when the requirements that the high-voltage side of the grounding switch is not electrified and the grounding switch is in an off-position state are met, the switch is controlled to be closed to enable the divider resistor to be in short circuit, electrification of the locking electromagnet coil is not affected, and locking of a grounding switch operation loop is not affected; after the locking electromagnet coil is powered on, the control switch is switched off to enable the divider resistor to be connected into a circuit, the divider resistor plays a role in dividingvoltage, current passing through the locking electromagnet coil is reduced, and the problem that large burnout hidden danger exists due to the fact that large current passes through the locking electromagnet coil for a long time is effectively solved.
