Abstract
A motor manipulating mechanism for electric switch is composed of motor, speed reducer, tooth-embedded clutch and casing. Said motor is an AC/DC one with forward with backward rotations. Said speed reducer is a harmonic annular flexible-wheel one matched between motor and clutch. Its advantages include simple structure and high safety and reliability.
Description
The invention belongs to a kind of electric operating mechanism, it can be used for high pressure, middle pressure or low tension switch powder operation device.
Existing switch operating mechanism has that manual (as " high voltage isolator operating mechanism ", ZL86208982 stops; " operating mechanism of switching device ", ZL88208777 stops), have vapour-pressure type (as " independent pneumatic mechanism ", ZL87206265 stops; " the air operating mechanism of circuit breaker adapted ", ZL95205571), DYN dynamic (as " the electronic powder operation device of high voltage isolator ", ZL88209272 stops, and its drive system is three grades of deceleration transmission) arranged.Have in the electrodynamic type by the plug-in strip of the direct or indirect actuating isolating switch of connecting lever axle and divide and close (as " spiral is paid the operating mechanism of link rod transmission ", ZL8820288 stops), have the band spring (as " spring operating mechanism ", ZL88214657 stops; " energy storage device of high-voltage switch gear spring operating mechanism ", ZL95230789; " energy storage operation machine of insulation gas filled high-voltage circuit-breaker pole ", ZL96192221; " outdoor high-voltage vacuum breaker operating mechanism ", ZL96232294; " primary cut-out powder operation device ", ZL96238300; " indoor high-voltage on-load switch formal dress formula operating mechanism ", ZL96243155; " the spring energy-storage hydraulic actuating mechanism of mesohigh circuit breaker ", ZL97216865; " a kind of switch spring powder operation device ", ZL97239787; " outdoor AC high-voltage on-load switch spring operating mechanism ", ZL99219074; " middle pressure vacuum circuit-breaker spring operating mechanism " ZL99224006), has (as " a kind of isolating switch operating mechanism ", ZL92214525 stops) of driving worm mechanism by gear mechanism or the like.
Above-mentioned electrodynamic type operating mechanism is by the motor energy storage, dropout separating brake after spring closes a floodgate.This mechanism structure complexity, volume is big, Heavy Weight, and basically by four connecting rod mechanical connections, poor reliability, easy break-down, normal maintenance.
" the electronic powder operation device of high voltage load isolating switch " (ZL94224514), form by motor, transmission mechanism, electric control loop, switching manipulation bar, spindle turning device, clutch, safe coupled axle-pin, hand-operating device and casing etc., the final stage that it is characterized in that transmission mechanism is the spiral reduction gearing mechanism that is provided with spindle turning device, clutch is the mechanical type jaw clutch, and be provided with the clutch interlocking device etc. that automatically resets, its structure more complicated that still seems.
The object of the present invention is to provide that a kind of volume is little, the electric operating mechanism of dependable performance, minimum maintenance.
For achieving the above object, the solution that the present invention takes is: a kind of electric operating mechanism, comprise motor, decelerator, jaw clutch, casing, decelerator is a harmonic wave ring-shape flexspline decelerator, the one end is connected with motor, the other end is connected with jaw clutch, is in the top of mechanism; One end of jaw clutch has gear and is connected with the travelling gear combination that is in the middle part, is connected with the transmission output shaft of bottom then; Motor is the alternating current-direct current clockwise and anticlockwise motor.
The present invention compared with prior art has following good effect:
1, owing to adopt harmonic wave ring-shape flexspline decelerator, this harmonic wave ring-shape flexspline decelerator speed reducing ratio is big, deceleration is steady, rotary speed precision is high, can more correctly grasp the speed and the time of deceleration, makes that the entire mechanism compact conformation is simple, volume is little.
2, by jaw clutch, will manually separate safely and effectively, make that mechanism's service life is long, few maintenance with electronic two kinds of modes of operation.
3, because simple in structure, and do not have the connecting rod mechanical connection and without spring close, separating brake, good reliability.
The invention will be further described below in conjunction with embodiment and accompanying drawing thereof.
Fig. 1 is the structural representation of present embodiment.
In Fig. 1: 1-alternating current-direct current clockwise and anticlockwise motor, 2-harmonic wave ring-shape flexspline decelerator, 3-jaw clutch, the combination of 4-travelling gear, 5-casing, 6-gear, 7-transmission output shaft.
As shown in Figure 1, a kind of electric operating mechanism comprises motor, decelerator, jaw clutch 3, casing 5, and decelerator is a harmonic wave ring-shape flexspline decelerator 2, and the one end is connected with motor, the other end is connected with jaw clutch 3, is in the top of mechanism; One end of jaw clutch 3 has gear 6 and is connected with the travelling gear combination 4 that is in the middle part, is connected with the transmission output shaft 7 of bottom then; Described motor is an alternating current-direct current clockwise and anticlockwise motor 1.Alternating current-direct current clockwise and anticlockwise motor 1 is by in the alternating current-direct current 220V, and the voltage that is added in jaw clutch 3 through transformation is the 24V safe voltage.Alternating current-direct current clockwise and anticlockwise motor 1 energising back is with the starting of 3000rpm rotating speed, and slowing down through harmonic wave ring-shape flexspline decelerator 2 is 28rpm, drives travelling gears combination 4 actions by jaw clutch 3 and makes that switch closes, separating brake.When removing alternating current-direct current clockwise and anticlockwise motor 1 voltage, jaw clutch 3 separates, and switch stops action, and at this moment directly manually actuating need not to be provided with any blocking mechanism.
The present invention is with casing 5 supportings and hold known alternating current-direct current clockwise and anticlockwise motor 1, harmonic wave ring-shape flexspline decelerator 2, jaw clutch 3, travelling gear combination 4, gear 6, they are organically made up as a whole, become a kind of novel electric operating mechanism.It is not only simple in structure, and its fail safe all is better than the similar electric operating mechanism that is using at present with reliability.It can be widely used for the powder operation device of appliance switch, no matter be high pressure, middle pressure or low tension switch.
