Abstract
The invention relates to a rapid switching mechanism of a dual power changeover switch. The rapid switch mechanism comprises a mechanism body, the two ends of the mechanism body are provided with a solenoid A and a solenoid B respectively, the middle portion of the mechanism body is provided with a rotating shaft, one end of the rotating shaft is connected with a power spring A and a power spring B of the mechanism body, the power spring A and the power spring B are arranged at the two sides of the rotating shaft respectively, the other end of the rotating shaft is connected with a movable rod, the rotating shaft is integrated with the movable rod, a movable iron core sleeves the rotating shaft, and the movable iron core can drive the rotating shaft to move horizontally. The mechanism is simple in structure, convenient to assemble, and high in switching speed, is prevented from being stuck, and does not influence the arc extinguishing performance.
Description
Technical field
The invention belongs to low-voltage electrical apparatus structure-design technique field, be specifically related to a kind of switching mechanism for dual-power transfer switch.
Background technology
The topmost performance index of automatic transfer switching electric appliance are short circuit making capacity, short circuit breaking capacity, electrical endurance and mechanical endurance, and device for switching Structure and Properties index effect has direct relation.The automatic transfer switching electric appliance of traditional more than 630A specification uses dual-mechanism or double electromagnet interlock, its shortcoming is adopting the quality of fit of many its each parts of complex structure of dual-mechanism its parts of transmission to require height, and break down often; Adopt double electromagnet interlock to need in debugging and maintenance the action of electromagnet power switch ability, otherwise automatic change-over just can not use.Be the diverter switch electrical equipment of the place use that 630A electricity consumption requirement can not have a power failure both at home and abroad in rated current, great majority are all that two the omnipotent breaker switches adopted add switch controller and mechanical interlocking is formed, adopt above-mentioned two kinds of duplicate supply switching modes, have certain switching effect, but unparalleled point of position also exist switching longer, in handoff procedure, have obvious interruption duration and the weak point such as easily to break down.
Summary of the invention
The present invention is intended to address the aforementioned drawbacks, and provides a kind of switch speed fast, does not affect the quick switching mechanism of the double power supply converting switch of arc extinction performance.
In order to overcome the defect existed in background technology, the technical solution adopted for the present invention to solve the technical problems is: a kind of quick switching mechanism of double power supply converting switch, comprise body, described body two ends are respectively equipped with A solenoid and B solenoid, rotation axis is provided with in the middle part of body, rotation axis one end connects a-power supply spring on body and B-source spring respectively, a-power supply spring and B-source spring are separately positioned on the both sides of rotation axis, the rotation axis other end connects moving lever, rotation axis and moving lever adopt integrated formed structure, rotation axis is arranged with motion iron core, motion iron core can drive rotation axis to realize transverse movement.
In a preferred embodiment of the present invention, rotation axis is provided with projection, and described motion iron core is provided with the hole corresponding with projection, and projection can transverse movement in hole.
The invention has the beneficial effects as follows: mechanism structure is simple, easy to assembly, and can not be stuck, switch speed is fast, does not affect the performance of arc extinguishing.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation one of the present invention;
Fig. 2 is structural representation two of the present invention;
Fig. 3 is stereogram of the present invention.
Embodiment
A kind of quick switching mechanism of double power supply converting switch as shown in Figure 1 to Figure 3, comprise body 1, body 1 two ends are respectively equipped with A solenoid 2 and B solenoid 3, rotation axis 4 is provided with in the middle part of body 1, rotation axis 4 one end connects a-power supply spring 5 on body and B-source spring 6 respectively, a-power supply spring 5 and B-source spring 6 are separately positioned on the both sides of rotation axis 4, rotation axis 4 other end connects moving lever 7, rotation axis 4 and moving lever 7 adopt integrated formed structure, ironware welding manner relatively, lifting process level greatly, and integral structure is more firm, rotation axis 4 is arranged with motion iron core 8, motion iron core 8 can drive rotation axis 4 to realize transverse movement, rotation axis 4 is provided with protruding 9, and motion iron core 8 is provided with the hole 10 corresponding with projection 9, and motion iron core 8 is by the attraction of solenoid, protruding 9 can transverse movement in hole 10, the transverse movement of convex 9 drives the transverse movement of rotation axis 4, finally realizes the motion of moving lever, realizes closing a floodgate and separating brake.
After the energising of B solenoid, faraday electromagnetic induction is utilized to produce powerful magnetic field, attractive motion iron core is to B lateral movement (motion iron core drives rotation axis to B lateral movement), and compress a-power supply spring, B-source spring energy-storage, after actuating strut moves to balance point, now switch utilizes a-power supply spring, B-source spring releases energy rapidly, add that the electromagnetic actuation force of B solenoid acts on the rotating shaft together, realize moving lever to B to motion, play combined floodgate effect fast, separating brake is also like this, this mechanism structure is simple, easy to assembly, and can not be stuck, fast arc extinction is played at low-voltage electrical apparatus, there is good effect.
