Abstract
Description
Technical Field
[0001] This invention relates to the field of outgoing line operating mechanisms, and in particular to an outgoing line operating mechanism for a 40.5KV combined electrical appliance. Background Technology
[0002] The outgoing line operating mechanism of combined electrical appliances generally adopts an integrated design of three-position switch, vacuum circuit breaker, surge arrester and current transformer, and achieves electrical isolation through air insulation or less SF6 gas insulation. The current outgoing line operating mechanism of combined electrical appliances cannot reach 40.5KV.
[0003] Therefore, it is necessary to design a 40.5KV combined electrical appliance outgoing line operating mechanism. Summary of the Invention
[0004] The technical problem to be solved by this invention is that the current combined electrical appliance outgoing line operating mechanism cannot reach 40.5KV.
[0005] To solve the above-mentioned technical problems, one technical solution adopted by the present invention is: providing a 40.5KV combined electrical appliance outgoing line operating mechanism, the outgoing line operating mechanism including a mechanism base, an energy storage shaft with gears rotatably mounted on the mechanism base, an intermediate gear rotatably mounted on the mechanism base, the intermediate gear meshing with the gears of the energy storage shaft, a closing shaft with gears rotatably mounted on the mechanism base, the intermediate gear meshing with the gears of the closing shaft, an output shaft mounted on the mechanism base, blades mounted on the output shaft, a opening spring mounted on the blades, and a closing spring mounted on the mechanism base, the closing spring being connected to the closing shaft.
[0006] A roller seat is mounted on the output shaft, and a closing roller and a opening roller are rotatably connected to both ends of the roller seat. A cam is mounted on the closing shaft, and the closing roller is located on one side of the cam.
[0007] A tripping coil is installed on the mechanism base, a tripping half-shaft is installed on the mechanism base, a tripping push plate is installed on the tripping half-shaft, and the tripping coil is opposite to the tripping push plate.
[0008] A tripping knob is installed on the top of the tripping half shaft.
[0009] A motor is mounted on the base of the mechanism, and the motor controls the rotation of the energy storage shaft.
[0010] The beneficial effects of this invention are as follows: The energy storage shaft is operated manually via a handle (or electrically via a motor). The energy storage shaft transmits energy to the closing shaft through a transition gear, causing the closing shaft to rotate 180 degrees clockwise. At the same time, the closing shaft stores energy in the closing spring. When the closing shaft has rotated 180 degrees, the closing spring directly drives the closing shaft to close the circuit. At this time, the cam on the closing shaft strikes the closing roller on the output shaft, causing the output shaft to rotate counterclockwise, closing the switch and storing energy in the opening spring. The opening roller passes through the opening shaft, which engages with the opening half-shaft, keeping the mechanism in the closed state. Manually rotating the opening knob (or using an electric coil to trip and impact the opening push plate) causes the opening half-shaft to rotate and release the energy of the opening spring, driving the switch on the output shaft to open.

[0016] A tripping coil 13 is installed on the mechanism base 1, a tripping half shaft 14 is installed on the mechanism base 1, and a tripping push plate 15 is installed on the tripping half shaft 14. The tripping coil 13 and the tripping push plate 15 are opposite each other.

[0018] A motor 17 is installed on the mechanism base 1, and the motor 17 controls the rotation of the energy storage shaft 2.
[0019] The energy storage shaft is operated manually via a handle (or electrically via a motor). The energy storage shaft transmits energy to the closing shaft through a transition gear, causing the closing shaft to rotate 180 degrees clockwise. At the same time, the closing shaft stores energy in the closing spring. When the closing shaft has rotated 180 degrees, the closing spring directly drives the closing shaft to close the circuit. At this time, the cam on the closing shaft strikes the closing roller on the output shaft, causing the output shaft to rotate counterclockwise, closing the switch and storing energy in the opening spring. The opening roller passes through the opening shaft, which engages with the opening half-shaft, keeping the mechanism in the closed state. Manually rotating the opening knob (or using an electric coil to trip and impact the opening push plate) causes the opening half-shaft to rotate and release the energy of the opening spring, driving the switch on the output shaft to open.
