The grounding operation mechanism on the special mechanism for the load switch adopts a grounding motor to realize electric grounding, and the working mode during grounding is as follows: the work of the grounding motor drives the worm to rotate, the worm drives the worm wheel to rotate, and the worm wheel drives the grounding operating shaft to rotate, so that the grounding spring is stretched to store energy, and the purpose of electric grounding is achieved. The utility model discloses the mode that the load switch private organization of electronic ground connection realized the ground connection operation with the motor-driven replaces original manual ground connection has promoted whole electrical system's automation and intelligent degree, and electronic ground connection action is steady reliable, the precision is high, can reduce the impact between the earthing operation mechanism spare part, improves the life of whole load switch private organization.

The utility model discloses further set up to be fixed with the separation and reunion wheel on the worm wheel, be provided with the carousel in the worm wheel, the symmetry is provided with two swing arms on the carousel, the swing arm passes through pin swing joint on the carousel, be connected with the separation and reunion spring on two swing arms, the interior week of formation evenly distributed's of separation and reunion wheel recess, the swing arm leans on outer one side to form the lug, the lug sets up respectively in the recess, the carousel leans on bottom plate one side to form the axle sleeve, the ground connection operating axis is connected in the axle sleeve.

The lug is supported to the recess of clutch pulley under the effect of separation and reunion spring on the aforesaid through the swing arm for when the worm wheel rotated, the clutch pulley also can drive the carousel and rotate, thereby drives the rotation of ground connection operating axis, realizes load switch specialized mechanism's ground connection operation.

The utility model discloses it has the rachis to wear to put on the carousel further, be provided with separation and reunion tooth and separation and reunion piece on the rachis, the separation and reunion tooth is located between two swing arms, the separation and reunion piece is located the top of separation and reunion spring and swing arm.

The rotating gear shaft drives the clutch gear to rotate any one of the swing arms around the pin, the protruding block of the swing arm is separated from the groove of the clutch wheel, the rotating disc is separated from the clutch wheel, the grounding spring releases energy, and the grounding mode of the special mechanism for the load switch can be manually closed.

This practicality further sets up to the axle sleeve internal fixation has the adapter sleeve, the one end setting of ground connection operating axis is in the adapter sleeve.

This practicality further sets up to be provided with two for the motor mounting panel, worm wheel and worm all set up between two motor mounting panels.

The motor mounting plate enables the transmission matching of the worm wheel and the worm to be more stable and reliable, and ensures that the transmission mechanism does not deviate or misplace.
