Dynamic pitman shaft 60.
It should be understood that driving gear on worm 13 by motor 12, gear on worm 13 is engaged with linkage gear 141 again to be turned
It is dynamic, so that transmission direction is changed, changes the rotation direction of pitman shaft 60 eventually by driving gear set 14, to make breaker 100
Handle 40 realize manual divide-shut brake operation or automatic breaking-closing operating.When driving gear set 14 the second Transmission gear 143 with
When the turbine 144 that links engages, control circuit controls motor 12 and rotates, and so that breaker 100 is obtained handle 40 and realizes automatic divide-shut brake behaviour
Make；When the second Transmission gear 143 of driving gear set 14 is detached with linkage turbine 144, driving gear set 14 can not the company of drive
60 rotational handle 40 of bar axis, the trip assembley therefor 26 of the combination of handle 40 at this time realize manual divide-shut brake operation.Snail is driven by motor 12
Bar gear 13 and driving gear set 14, and the second Transmission gear 143 is combined to engage or detach with linkage turbine 144, compared to original
It is single to pull handle 40 and driving mechanism is placed on hull outside, the standard degree of short-circuiting device is improved, installation difficulty is reduced,
Improve operational stability.
Further, the diameter of the first transmission gear be more than the second transmission gear diameter, the second Transmission gear 143 it is straight
Diameter is more than the diameter of the second transmission gear.The setting of different size diameter can preferably match the installation of driving gear set 14
Operating mode ensure that the stable operation of driving gear set 14.
Further, the second Transmission gear 143 is 1/4 partial gear, and the face of gear of the second Transmission gear 143 is divided into two
Part, a portion, which is the circumference of entire second Transmission gear 143, all has gear, has 1/4 in the flank profil of a portion
Perimeter has gear, and 3/4 is arcuate structure.Linkage turbine 144 is 1/4 partial gear, which is defined as this
There is 1/4 perimeter that there is gear in the flank profil of linkage turbine 144,3/4 is arcuate structure.Pass through the endless of the second Transmission gear 143
The gear engagement of the partial gear of all gear and linkage turbine 144, realizes the second Transmission gear 143 of driving gear set 14
Linkage turbine 144 between engagement or detach, provided for the miniature circuit breaker 100 with novel zero sequence mutual inductor installation structure
The simple technical support easily realized.
The foregoing is merely the preferred embodiment of the present invention, are not intended to limit the scope of the invention, every at this
Under the inventive concept of invention, using equivalent structure transformation made by description of the invention and accompanying drawing content, or directly/use indirectly
In the scope of patent protection that other related technical areas are included in the present invention.
