Make, so that connecting plate be driven to move, and then connecting lever rotation is driven, to realize on/off switch.The invention uses push-pull electromagnet knot
Structure substantially reduces starting current, expands the application range of permanent magnetic mechanism switch；Not only simplify accumulator, Er Qie great
It reduces costs greatly；Simultaneously as positive anti-magnetic acts on simultaneously, the reliability of movement is substantially increased, movement is substantially reduced
Time；On/off switch coil only in switch on/off switch moment electrification, is usually maintained at on/off switch position by permanent magnet, substantially reduces
Loss of the coil to electric energy.
But the on-load switch directly drives connecting plate using electromagnet, electromagnet by biggish resistance, need compared with
Big moment driving current can just make magnet spool generate enough magnetic force to drive its movable head, thus could the company of driving
Plate movement, so that the power consumption of the on-load switch or relatively high, there are also reduced spaces.
Utility model content

Specific embodiment
Referring to Fig.1, a kind of low-watt consumption magnetic dynamic load switch, including frame 1 and the mounting plate being connect with frame 12, in frame
Insulator 3 is arranged in top in 1, the interior lower part of frame 1 is provided with vacuum interrupter 4, vacuum interrupter 4 is located at insulator
3 underface is provided between the lower end of insulator 3 and the upper end of vacuum interrupter 4 and is flexible coupling, the bottom of vacuum interrupter 4
End is connect by insulated support with the bottom of frame 1.The on-load switch further includes transmission mechanism, and transmission mechanism includes connecting plate 6
With connecting lever 5, connecting plate 6 and one end of connecting lever 5 are hinged, and the top of the middle part of connecting lever 5 and frame 1 is rotatablely connected, the lower end of connecting lever 5 with
Insulator 3 is hinged.
The on-load switch further includes electromagnet 8 and lever 10, and the body of rod and mounting plate 2 of lever 10 are rotatablely connected, electromagnet 8
Main body and mounting plate 2 it is hinged, the movable head 9 of electromagnet 8 and one end of lever 10 are hinged, the other end and connecting plate 6 of lever 10
Hingedly, lever 10 is obliquely installed, the fulcrum of lever 10 be greater than at a distance from the connecting pin of movable head 9 away from it fulcrum away from its with
The distance of the connecting pin of connecting plate 6.
The action process of the on-load switch are as follows: the movable head 9 of electromagnet 8 acts, and activation lever 10 rotates, and drives connecting plate 6
Movement completes on/off switch movement so that connecting lever 5 be driven to rotate.
According to 10 labour-saving principle of lever, after lever 10 is added, electromagnet 8, which only needs to export lesser driving force, to be driven
