Embodiment Construction
[0016] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0017] see figure 1 , figure 2 , image 3 , a structural schematic diagram of a three-position isolation-grounding operating mechanism using a ball screw in the present invention, which includes a motor 1, a bevel gear 2 and a bevel gear 3, a ball screw 4, a driving slider 5, a guide rod 6, and a roller 7 , shift fork 8, rotating shaft 9, the motor 1 rotates to drive the bevel gear 2 and the bevel gear 3 to rotate, and drives the ball screw 4 to rotate, and the drive slider 5 runs through the ball screw 4 and the two guide rods 6 , the axis of the ball screw 4 is kept parallel to the axes of the two guide rods 6. When the ball screw 4 rotates, the driving slider 5 will move linearly along the guide rod 6, and the inside of the driving slider 5 is connected with the ball screw 4. There are balls that reduce friction...

The invention discloses a three-position-isolation-grounding operating mechanism adopting a ball screw. The three-position-isolation-grounding operating mechanism comprises a motor, a bevel gear and a bevel gear, the ball screw, a driving sliding block, guiding rods, a rolling wheel, a shifting fork and a rotary shaft; the three-position-isolation-grounding operating mechanism is characterized in that the rotation of the motor drives the bevel gear and the bevel gear to rotate to drive the ball screw to rotate; the driving sliding block runs through the ball screw and the two guiding rods; the axial line of the ball screw is parallel to that of the two guiding rods; rolling beads for reducing friction are arranged between the interior of the driving sliding block and the ball screw; the rolling wheel is fixed on the upper surface of the driving sliding block; the rolling wheel is in contact with the shifting fork; and the shifting fork is fixed on the rotary shaft. The three-position-isolation-grounding operating mechanism has the characteristics of low cost, high precision, simple structure, low friction resistance, flexible operation, long service life, accurate positioning, and high transmission efficiency.
Description
technical field [0001] The invention relates to the technical field of electric power transmission and distribution, in particular to a [0002] Three-position isolated-grounded operating mechanism. Background technique [0003] Existing power equipment (such as GIS: short for fully enclosed combined electrical appliances) has a set of operating mechanisms for the isolating switch and the grounding switch. Such a design has a large number of parts, high cost, low efficiency, poor precision, and complex structure. Human misoperation will bring faults to the power system. Contents of the invention [0004] For the shortcomings and deficiencies existing in the prior art, the purpose of the present invention is to provide [0005] A three-position isolation-grounding operating mechanism using a ball screw, which has the characteristics of low manufacturing cost, high precision, high efficiency, long life and simple structure. [0006] The technical solution adopted to reali...
