The utility model compared with prior art, and is simple in structure, and dependable performance guarantees that the high voltage load isolating switch accurately puts in place, makes it not be subjected to any impact; Because of being provided with electric and mechanical two kinds of protections, prolonged the useful life of high voltage load isolating switch and powder operation device thereof.
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing 2 is electronic powder operation device embodiment 2 principle schematic of high voltage load isolating switch, and 18 is tooth bar among the figure, and 19 is sector gear.
Its spindle turning device is located at the final stage that spiral subtracts the biography speed driving mechanism in the present embodiment, and this spindle turning device is made up of shift fork 8, driving lever 5, roller 7, main shaft 6, and the driving lever 5 that roller 7 is housed is connected on the screw 9, and shift fork 8 is connected with main shaft 6.Be provided with safe coupled axle-pin between the sleeve pipe of main shaft and isolator operation bar.
Hand-operating device is provided with handle and manual linking lever, and handle is connected with manual linking lever through the lead screw shaft of transmission mechanism, and the other end of this linking lever is connected with the clutch interlocking device that automatically resets.
When high voltage load isolating switch (hereinafter to be referred as isolating switch) combined floodgate electric operating, press switch knob, motor 1 loop is connected, the motor 1 that has decelerator is just changeing, transmission of power is given the lead screw shaft 10 of screw-drive mechanism by jaw clutch 2, screw 9 is along being fixed on guide post 4 on the casing 3 to left, driving lever 5 forces shift fork 8 to rotate around its main shaft 6 clockwise directions on the screw 9, main shaft 6 is locked by safe shaft coupling with the output shaft sleeve pipe on the isolating switch and is connected, after isolating switch closes a floodgate and puts in place, the auxiliary switch action, the power supply of motor 1 is cut off.Motor 1 is because of inertia continues rotation, is located at driving lever 5 on the screw-drive mechanism still to left.Because shift fork 8 can only turn an angle around its main shaft 6, so after the isolating switch combined floodgate puts in place, roller 7 on the driving lever 5 rolls along the left medial surface of shift fork 8 reposefully, shift fork 8 remains static all the time, after guaranteeing that isolating switch accurately puts in place, be not subjected to the influence of motor 1 inertia, without any impact.
When the electronic actuating of isolating switch separating brake, press opening button, motor 1 loop is connected, have motor 1 reverse rotation of decelerator, transmission of power is given the lead screw shaft 10 of screw-drive mechanism by jaw clutch 2, screw 9 is along being fixed on guide post 4 on the casing 3 to right translation, driving lever 5 on the screw 9 forces shift fork 8 after its main shaft 6 counterclockwise turns an angle, the isolating switch separating brake puts in place, the auxiliary switch action, and the power supply of motor 1 is cut off, motor 1 continues rotation because of inertia, driving lever 5 is still to right translation, but the roller 7 on the driving lever 5 is the Right Inboard face rolling along shift fork 8, and shift fork 8 remains static all the time.
When manual operation, handle 17 is inserted the external part of lead screw shaft 10, handle 17 counterclockwise rotates manual linking lever 16, drive interlocking clutch bar 14 and move right, the trip(ping) lever 12 that is located on the interlocking clutch bar 14 is thrown off jaw clutch 2, and the decelerator of motor 1 separates with screw-drive mechanism, simultaneously, the back-moving spring 11 that is located on the interlocking clutch bar 14 is stretched, the rotation of handle 17 clockwise directions, isolating switch separating brake; Handle 17 rotation counterclockwise, isolating switch closes a floodgate.After isolating switch branch, combined floodgate put in place, continue rotation as handle 17, the rotation of lead screw shaft 10 makes screw 9 continue to the right or to left along guide post 4, at this moment because of minute, closing a floodgate puts in place, roller 7 on the driving lever 5 is just along side roll in the right left side of the Right Inboard face of shift fork 8, and shift fork 8 keeps transfixion.When handle 17 when the external part of lead screw shaft 10 is withdrawn from, back-moving spring 11 on the interlocking clutch bar 14 shrinks automatically, drive interlocking clutch bar 14 to left movement, trip(ping) lever 12 is stirred jaw clutch 2 makes it chimeric, the decelerator of motor 1 is connected with the lead screw shaft 10 of screw-drive mechanism by jaw clutch 2, returns to electronic actuating state.
After the electronic branch of isolating switch, combined floodgate put in place, if other electrical equipment such as auxiliary switch breaks down, cause screw 9 to the right or left translation distance surpass normal value, at this moment, screw 9 promotes right limit bar 15 or promotes left limit lever 13, and interlocking clutch bar 14 is moved right, trip(ping) lever 12 forces jaw clutch 2 to be thrown off, screw-drive mechanism runs out of steam, and self damaging of electric operating mechanism avoided in then lead screw shaft 10, screw 9 and driving lever 5 stop motion immediately.
When isolating switch when there was a mechanical failure, the moment overrate that divides, closes a floodgate, the safe coupled axle-pin that adds between the main shaft of isolator operation bar and this device is cut off, and isolating switch runs out of steam, thereby has realized the protection to isolating switch.
Embodiment 2:
The course of action of the electronic branch of high voltage load isolating switch, combined floodgate, and the manual operation process is all identical with embodiment 1.Only driving lever 5, the roller 7 with spindle turning device is designed to tooth bar 18, and shift fork 8 is designed to sector gear 19, and tooth bar is connected with screw, and gear is connected with main shaft.
