Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings:
Fig. 1 is the STRUCTURE DECOMPOSITION figure of the utility model specific embodiment;
Fig. 2 is the schematic diagram that the utility model specific embodiment (taking the state of loam cake apart) connects with circuit breaker.
Embodiment:
As shown in Figure 1 and Figure 2, the operating mechanism of the utility model double power supply automatic transfer switch comprises motor 1, transmission mechanism 2, switch transition shifting block 3 and base 4, two switch transition shifting blocks link also in opposite direction by transmission mechanism and motor formation, and straight line moves, the purpose of transmission mechanism is to give the switch transition shifting block with the transmission of power of motor, gyration is become straight line move, the structure of transmission mechanism can be used structures such as rack-and-pinion transmission, friction pulley transmission and chain drive.Use the rack-and-pinion drive mechanism in the most preferred embodiment of the present utility model, transmission mechanism 2 comprises reducing gear 21 and travelling gear 22, travelling gear 22 is located on the base, switch transition shifting block 31,32 is located at the both sides of travelling gear 22, two inboards are respectively equipped with the tooth bar 35 that is parallel to each other and are meshed with travelling gear 22, switch transition shifting block 3 also is provided with the gathering sill parallel with tooth bar 33 and constitutes slide-and-guide with base and cooperates, and the two switch transition shifting blocks outside is provided with the bayonet slot 34 that matches with the mains switch handle and constitutes described coupling mechanism.Reducing gear 21 common and motors 1 as a whole (adopting the motor of band reducing gear), installation for the ease of motor, the utility model also is provided with and the fastening loam cake that connects 5 of base 4 screws, motor 1 and reducing gear 21 are connected and fixed in loam cake 5, and the power transmission shaft of reducing gear passes in the centre bore that loam cake 5 extends to travelling gear 22.Switch transition shifting block 31,32 stage casing (is considered from angle of mechanics, position near tooth bar is good more more) alignment pin 41 that is provided with of the gathering sill 33 and the base 4 that are provided with constitutes slide-and-guides and cooperates, the quantity of gathering sill 33 can be one, also can adopt two (can increase stability), the quantity of the alignment pin that cooperates with single gathering sill can be one or two, best mode is that two gathering sills cooperate with three alignment pins, should preferentially adopt the fit system (considering) of two alignment pins from the mechanics angle near the gathering sill of tooth bar, another gathering sill cooperates with an alignment pin, and the end of alignment pin 41 cooperates the constraint that constitutes the switch transition shifting block with collar 44.The power of motor 1 is by the transmission of reducing gear 21 (purpose of deceleration is in order to improve moment of torsion and to reduce rotating speed) and travelling gear 22, make left-handed opening conversion shifting block 31, right switch transition shifting block 32 along opposite direction linear slide, thereby realize that left circuit breaker 7 is in different states with right circuit breaker 8, needs are connected, and another must disconnect earlier.Because of the switch transition shifting block is a rectilinear motion, can not produce the effect of button square to the handle of circuit breaker, thus the useful life of improving circuit breaker, this is particularly outstanding characteristics of the utility model.For the purpose of more reliable, also be provided with a guide vane end stop 6 in the most preferred embodiment of the present utility model, guide vane end stop 6 is positioned at the outside that switch transition shifting block 31,32 can be realized the sliding end of power supply closure, the center of guide vane end stop 6 is provided with a pin-and-hole and constitutes the rotation cooperation with the bearing pin 42 (end of bearing pin 42 cooperates the formation axial limiting with collar 44) that base is provided with, the sliding end of the end of guide vane end stop 6 and switch transition shifting block 3 leans, and the purpose of guide vane end stop is to prevent that two circuit breakers from connecting simultaneously.Consider from safer angle, closed again another circuit breaker after should allowing closed originally circuit breaker disconnect fully, if the whole circumference of travelling gear 22 is equipped with profile of tooth, then closing with closed operating on synchronously of two circuit breakers carried out, time difference between the two is very little, has certain risk.So, in most preferred embodiment of the present utility model, the profile of tooth scope of its travelling gear 22 is less than 180 degree (but not being less than 90 degree), originally closed again another circuit breaker after closed circuit breaker is disconnected fully, again because dual-power transfer switch controller (the applicant's separate case application) in the extremely unsettled occasion of some power supply supply, need make two circuit breakers all be in off-state when power down, satisfy this kind control requirement, the circumferential profile of tooth scope that must make travelling gear is less than 180 degree.The length of the gathering sill 33 of switch transition shifting block is according to the stroke decision of the handle of circuit breaker, can prevent that the switch transition shifting block from not producing destruction to circuit breaker, in order to reduce Motor torque the mechanism that is slidingly matched of switch transition shifting block there is destruction, it is that spacer pin 43 that circular arc stopper slot 221 and the base 4 of round dot is provided with constitutes and is slidingly matched that travelling gear 22 is axially arranged with its center, the motor power transmission is limited to the angular range of stopper slot 221.As shown in Figure 2, operating mechanism is installed on the substrate 9, at operating mechanism circuit breaker 7 and circuit breaker 8 be installed each side, also be provided with a Wiring port 10 on the substrate and connect, so constitute a complete double power supply automatic transfer switch with controller outside (the applicant has done the separate case application).
By as seen above-mentioned, because of operating mechanism adopts rack-and-pinion drive mechanism and position-limit mechanism, make the operating mechanism of the utility model double power supply automatic transfer switch have simple in structure, cost is low, high reliability features.
