With reference to Fig. 8 A, Fig. 8 B and Fig. 8 C, disclose the structure chart of energy storage component in electromagnetic protection device.Wherein Fig. 8 B is the sectional view of part A in Fig. 8 A, and Fig. 8 C is the sectional view of part B in Fig. 8 A.Fig. 8 A is the view shown from the dorsal part direction of Fig. 1.Energy storage component is arranged on upper shell 101, and energy storage component includes energy storage bar the 602nd, bimetallic adjusting rod the 601st, energy-stored spring and regulation screw 604.Wherein energy-stored spring is multiple, including energy-stored spring 603 and energy-stored spring 610.Bimetallic adjusting rod 601 extremely all coordinates across whole upper shell 101, multiple with multipole circuit breaker.Position in each pole of corresponding multipole circuit breaker; bimetallic adjusting rod 601 includes a contact bar 601B; each contact bar 601B and a pyromagnetic protected location 104 are corresponding; contact bar 601B coordinates with the bimetal leaf 121 of the Thermal protection unit in this pyromagnetic protected location 104; contact bar 601B coordinates with the inclined-plane 122 on bimetal leaf 121 top; there is interval between contact bar 601B and inclined-plane 122 when normal work, bimetal leaf 121 deformation when overload occurs makes inclined-plane 122 and contacts bar 601B and contact.Bimetallic adjusting rod 601 also includes that locking-bar 601A, locking-bar 601A make bimetallic adjusting rod 601 interconnect with the form of snap close with energy storage bar 602.As shown in Figure 8 C, locking-bar 601A and the snap close face 602A of energy storage bar 602 forms snap close.Regulation screw 604, for regulating the snap close amount of locking-bar 601A and snap close face 602A, rotates regulation screw 604, and the contact area between locking-bar 601A and snap close face 602A, i.e. snap close amount is changed.Energy-stored spring 603 is connected to bimetallic adjusting rod 601.When bimetal leaf 121 temperature distortion; contact bar 601B can be promoted; and driving bimetallic adjusting rod 601 to rotate, bimetallic adjusting rod 601 rotates around it center 601C and rotates, after bimetallic adjusting rod 601 rotates; locking-bar 601A trips with snap close face 602A; after tripping, energy-stored spring 603 drives bimetallic adjusting rod 601, and hits the operating mechanism of breaker under the cooperation of energy-stored spring 610; make operating mechanism produce dropout open circuit, reach the function of overload protection.In the energy storage component of the present invention, bimetal leaf 121 plays the effect of triggering, and the action hit is driven by energy-stored spring 603 and energy-stored spring 610, and therefore, the operating physical force hitting operating mechanism is stable.
Fig. 9 A and Fig. 9 B discloses the structure chart of adjusting part in electromagnetic protection device.Figure 10 A and Figure 10 B discloses the mounting structure figure of adjusting part.As it can be seen, adjusting part 107 is arranged on the pedestal of breaker.Adjusting part 107 includes mounting bracket the 173rd, the first adjusting rod 171 and the second adjusting rod 172.First adjusting rod 171 and the second adjusting rod 172 are rotatably installed in mounting bracket 173.With the junction of mounting bracket 173, there is packing ring 705 at the first adjusting rod the 171st, the second adjusting rod 172.The middle part of the first adjusting rod 171 has the first regulation gear 704, and the bottom centre of the first adjusting rod 171 has the first projection 708, and the bottom of the first adjusting rod 171 also has conical projections 701, and the tapered end of conical projections 701 has positioning bar.With reference to Fig. 8 A, upper shell 101 is provided with support 161, the bending part of support 161 has installing hole 605.First projection 708 of the first adjusting rod is arranged in installing hole 605, forms revolute pair.The positioning bar of the conical projections 701 of the first adjusting rod 171 is inserted in the regulating tank 601F of bimetallic adjusting rod 601.The middle part of the second adjusting rod 172 has the second regulation gear 703, and the bottom of the second adjusting rod 172 has the 3rd regulation gear 702, and the bottom centre of the second adjusting rod 172 has the second projection 707.With reference to Fig. 8 A, upper shell 101 has installing hole 606.Second projection 707 of the second adjusting rod is arranged in installing hole 606, forms revolute pair.3rd regulation gear 702 of the second adjusting rod is engaged with the geared parts 504 on bar 501.So that rotate during the first adjusting rod the 171st, the second adjusting rod 172 more accurate, mounting bracket 173 also has stepping support, the two ends of stepping support are profile of tooth end, and profile of tooth end 706 contacts with the first regulation gear 704 and is engaged, and profile of tooth end 705 contacts with the second regulation gear 705 and is engaged.When the first adjusting rod 171 or the second adjusting rod 172 rotate, profile of tooth end and regulation gear make adjusting rod stepping in the way of a tooth every time rotate.In other examples, the first adjusting rod 171 and the second adjusting rod 172 also can use the mode of damping rotary.
With reference to Figure 10 A and Figure 10 B, adjusting part 107 coordinates with geared parts 504 and bimetallic adjusting rod 601 respectively, realizes overload current and the regulation of snap action electric current.The positioning bar of the conical projections 701 of the first adjusting rod 171 is inserted in the regulating tank 601F of bimetallic adjusting rod 601, when rotating the first adjusting rod 171, the positioning bar driving conical projections 701 is subjected to displacement, and positioning bar drives bimetallic adjusting rod 601 transverse shifting by regulating tank 601F.Because the working face of bimetal leaf 121 is inclined-plane 122, therefore after bimetallic adjusting rod 601 transverse shifting, distance F between its contact bar 601B and inclined-plane 122 is changed.The size of overload current can be regulated after changing distance F.3rd regulation gear 702 of the second adjusting rod 172 is engaged with the geared parts 504 on bar 501.Rotating the second adjusting rod 172, by bite strap lever 501 transverse shifting of gear, the size of the dynamic air gap between iron core and static iron core of regulation after bar 501 transverse shifting, the size of air gap changes the size that can regulate wink streaming current.
The magnetic of the electromagnetic protection device of the present invention protects spring in assembly to provide fixing interior counter-force, and this fixing interior counter-force is adjustable.This magnetic protection assembly makes only to need when design to consider one parameter of air gap, and design difficulty is greatly lowered.
Above-described embodiment is available to be familiar with person in the art and realizes or use the present invention's; those skilled in the art can be without departing from the present invention in the case of the inventive idea; make various modifications or change to above-described embodiment; thus protection scope of the present invention is not limited by above-described embodiment, and should be the maximum magnitude meeting the inventive features that claims are mentioned.
