Abstract

The invention discloses a tri-position operating apparatus for a switching device used for operations of switch-on, switch-off and grounding operating positions of an isolating grounding switch of a high-voltage combination electric appliance. The forward and backward rotation of a single motor drives a gear pair/a worm and worm wheel pair/a geneva mechanism/an output gear to the output shaft to realize the tri-position batch operation. Driving pins are meshed with grooves of grooved wheels in the switch-on, switch-off and grounding positions; the positions of corresponding moving contacts are locked; and chains are driven by corresponding chain wheels on the corresponding grooved wheel shafts to drive an auxiliary switch geneva mechanism and gears to drive so as to realize the program-based behaviors of the isolation auxiliary switch/grounding auxiliary switch. By adoption of the operating apparatus, the tri-position moving contact error caused by mechanism clearance, component error, stress deformation and abrasion is eliminated; particularly in the switch-on-to-switch-off positions and the grounding-to-switch-off positions, the separate movement of the auxiliary switches of the isolation/grounding switches is carried out, so that the circuit design can be controlled conveniently. The tri-position operating apparatus is simple in structure, accurate in the tri-position and the rotary angle, stable, safe and reliable, and high in economic benefit.

Description

Device for switching three position operation device
Technical field
The present invention relates to device for switching electric operating mechanism field, particularly high-voltage combined electrical apparatus isolation earthing switch combined floodgate, separating brake, ground connection three position electrically operated device。
Background technology
High-voltage combined electrical apparatus develops to intellectuality, modularity, miniaturization, the detection of highly reliable, non-maintaining, real-time status, Fast-Maintenance direction, require traditional discrete formula isolating/grounding switch two-in-one, form three position operation devices of only one of which moving contact, a power source, reject the probability of line combined floodgate/live connection of ground wire with ground。
But due to joint gap, process and assemble cumulative error, stress deformation and parts depreciation, make switch on of moving contact, separating brake, earthing position inaccurate, have a strong impact on the dielectric strength of switch, temperature rise and dynamic and thermal stability, particularly divide and to be grounding to point position misaligned closing to, bigger negative error, instability occur, floats bigger at open position moving contact。
Domestic and international existing three-position switch actuating device: the employing bi-motor that has, double lead-screw/twin worm mechanism, Geneva mechanism transmission, two power sources, does not meet two-in-one principle, and open position moving contact floats;Some employing list motor/gear/Geneva mechanism transmissions;Single motor/cylindrical cam/the gear drive having;Single motor/gear/plane cam the transmission having。In the bigger and unstable angular error that open position all can produce to bear, the system inertia impact on output angle and position can not be eliminated, can not compensate moving contact due to gap, stress deformation, process and assemble cumulative error, abrasion cause defect, being difficult to arrive ideal position, mass production processes is poor。
Summary of the invention
(1) to solve the technical problem that
Present invention aim to overcome disadvantages mentioned above, it is desirable to provide a kind of device for switching three position operation device。
(2) technical scheme
For reaching above-mentioned purpose, the device for switching three position operation device of the present invention, including chassis component, driving device, electrical control protection device, torch interlock, it is characterized in that:
Chassis component is connected with case lid with hasp after being welding as one with base plate by surrounding casing, and industry rectangular connector, vent window, handle, manual operation valve, state instruction, manual operation hole, manual rotary operation Directional Sign, manual operation main points, selection switching manipulation program are arranged in casing surrounding;
Driving device is that motor drives gear, worm screw, worm gear successively;Drive pin on worm gear drives sheave, and sheave passes through gear wheel, little gear driven output shaft rotation, it is achieved combined floodgate, separating brake, earthed switch three position operation;Fluted roller shaft drives axle, side instruction axle, front instruction axle, location dish, driving dish, driven roller, special shape gear, gear, control cam by sprocket wheel, chain drive auxiliary switch;
Torch interlock includes chain support, manual hole jam plate, return spring, the chain cam of torch, extension spring fixing plate, the chain travel switch of torch。
Further, worm gear being connected to spacing roller, engage locking at combined floodgate, separating brake, ground connection three position drive pin with the groove in sheave, worm gear upper limit roller contacts with pallet, and restriction puts in place, and defensive position is dynamic to be operated。
Further, side has state to indicate, and point identification is wanted in manual operation valve, selection switch operation instruction, carrying handle, vent window, hasp, manual rotation Directional Sign and manual operation, has industrial rectangular connector later, for secondary circuit line。
Further; shown in electrical control protection philosophy Fig. 5 .1 of dual tandem; close separating brake KM1 in isolation and control loop; connect two travel switch CK2, CK8 making its action at different axis cams; with control loop being grounding to separating brake KM2, connect two and makes travel switch CK3, CK9 of its action at difference axis cams。When three position operation devices are from isolation " conjunction " position to the motion of isolation " dividing " position, the control line of motor is equiped with isolation point travel switch, isolation sub-control cam and isolation and divides that travel switch, two groups of sub-control cam of isolation repeat, series connection, be attached separately to the on/off device in two different rotating shafts;When moving in three position operation devices from " ground connection " to " dividing " position, the control line of motor is equiped with ground connection divide travel switch, ground connection sub-control cam and ground connection divide that travel switch, two groups of ground connection sub-control cam repeat, series connection, be attached separately to the on/off device in two different rotating shafts;So that the power supply of motor (50) can be cut off when this three position operation device is from isolation " conjunction " to " dividing " position or the motion of from " ground connection " to " dividing " position in time, completely, utterly, guarantee that motor (50) stops operating, fundamentally stop the offside situation at open position。
(3) beneficial effect
Compared with prior art, technical scheme has the advantage that the single motor operation three position switch of realization, closing a floodgate, separating brake, earthing position mechanical caging, the defect of floating without position, meet the two-in-one principle of single action contact/single power source, output shaft is positive differential seat angle in separating brake rotating position, moving contact can be compensated due to joint gap, cumulative error, deformation, the position deviation that abrasion causes, reach perfect condition, Geneva mechanism is utilized to eliminate the system inertia impact on output angle and position, isolation/ground connection auxiliary switch is two independent position switch, convenient and traditional secondary controls loop slitless connection, cam controller is adopted to carry out electric position control, simply, accurately, reliably, five is anti-chain complete, simply, reliably, convenient operating maintenance。
