Below in conjunction with Fig. 1 and 2, further describe the operation principle of device for indicating failure of electric apparatus of the present invention.
As shown in Figure 1, when electrical equipment is done the closing by hand operation, be that operating grip 1 moves to closing position along the F1 direction, cylindrical bearing pin 9c on the lever piece of operating mechanism moves along the F9 direction shown in Fig. 1, promote the block 3c on the indication piece 3, make indication piece 3 do counterclockwise to rotate, this moment described cylindrical bearing pin 9c the plane of cambered surface and block 3c between to contact be that line-face contacts, help reducing the frictional force between the contact-making surface, improve the robust motion between indication piece 3 and the described lever.The white index plane 3e that waits to do the indication piece 3 that counterclockwise rotates enters the window 10e position on the support 10, self-locking takes place in the snap close face 5a of the padlock face 3b of indication piece 3 and snap close piece 5, the white index plane 3e of indication piece 3 firmly is locked in the window 10e, is in " normally " state with indication electrical equipment.Under this kind state, if electrical equipment is done the manual brake separating operation, being operating grip 1 moves to the separating brake position along the rightabout of F1, bearing pin 9c on the lever piece of operating mechanism moves along the rightabout of F9, and break away from (not shown) with block 3c on the indication piece 3, at this moment, because indication piece 3 still is in self-locking state with snap close piece 5, so the white index plane 3e of indication piece 3 still firmly is locked in the window 10e, be in " normally " state with indication electrical equipment.
As shown in Figure 2, when electrical equipment generation electric fault, push rod 6 on the electrical equipment trip gear sends the action of threading off, this dropout action passes to the snap close face 5a of the snap close piece 5 of the triggering part 12 of operating mechanism and accident indicator respectively by dropout feeler 6b and fault feeler 6a, operating mechanism and accident indicator are triped, make operating grip 1 move to trip position along the F2 direction, bearing pin 9c on the operating mechanism lever piece moves along the F10 direction, because this moment, indication piece 3 was in unbuckled state with snap close piece 5, so under the torsional interaction of spring 4, indication piece 3 is made clockwise direction and is rotated, red index plane 3d is entered in the window 10e on the support 10, be in " fault " state with indication electrical equipment, this indicating status lasts till that always electrical equipment is once more till the closing by hand operation.
After electrical equipment is because of the generation electric fault, be in the disjunction state, once more operating grip 1 is carried out the closing by hand operation, with operating grip 1 when the F1 direction moves to closing position, the bearing pin 9c that is arranged on the lever of operating mechanism moves along the F9 direction, the block 3c that promotes on the indication piece 3 does counterclockwise to rotate, the white index plane 3e that treats indication piece 3 enters the window 10e position on the support 10, padlock face 3b on the indication piece 3 contacts with the snap close face 5a of snap close piece 5 and fastens, self-locking takes place, white index plane 3e firmly is locked in the window 10e, is in " normally " state with indication electrical equipment.Be assemblied in the spring 4 drive snap close pieces 5 that act on simultaneously on the indication piece 3 on the snap close piece 5 and turn clockwise, when operating grip 1 was finished closed procedure, indication piece 3 in the electric fault indicating mechanism and snap close piece 5 were also finished the locking of normal operating conditions.The snap close face 5a of the padlock face 3b of indication piece 3 and snap close piece 5 contacts under the effect of spring 4 by face, face and locks under visible this state from accompanying drawing.When operating grip 1 from closing position when the F1 rightabout moves to the separating brake position, the bearing pin 9c that is arranged on the lever of operating mechanism moves along the rightabout of F9, and break away from block 3c on the indication piece 3, indication piece 3 still keeps self-locking state with snap close piece 5, be that white index plane 3e on the indication piece 3 still firmly is locked in the window 10e on the support 10, be in " normally " state of manual brake separating with indication electrical equipment.As seen, can there be the potential safety hazard of the mistake indication of existing mechanism in device of the present invention.
Under "on" position, for example when electrical equipment generation leak current fault, tripping mechanism sends the instruction of threading off, push rod 6 on the tripping mechanism touches the triggering part 12 of operating mechanism and the shake-up face 5b on the snap close piece 5 by dropout feeler 6b and fault feeler 6a respectively, the tripping bar that promote the electrical equipment branch, closes contact mechanism is triped operating mechanism, simultaneously push rod 6 promotes snap close pieces 5, padlock face 3b on the indication piece 3 is triped with snap close face 5a on the snap close piece 5 separate.Divide, after closing the contact mechanism separating brake, bearing pin 9c resets, removed constraint to the block 3c of indication piece 3, operating grip 1 moves to trip position along the F2 direction, bearing pin 9c on the operating mechanism lever piece moves along the F10 direction, snap close piece 5 is rotated counterclockwise under the effect of spring force, the moment of torsion of spring 4 promotes that indication piece 3 does that clockwise direction rotates and in red index plane 3d enters window 10e on the support 10, the final electrical equipment of realizing is in the indication of " fault " state, the information of leak current fault state indication is stored reliably, can see red indication information on the indication piece 3 by the indication window 10e on support 10 shells.Under this state, the cylindrical bearing pin 9c of lever realizes that with the block 3c of indication piece 3 line, face contact once more, prepares for carrying out next time closed procedure.
In sum, use the interaction between indication piece 3, spring 4 and the snap close piece 5 of accident indicator of the present invention, the direct actuating member that the lever of operating mechanism is resetted as indication piece, need not directly to drive, carry out the like product volume that the electric fault indicating device resets and reduce greatly with operating grip 1 by operating grip 1; Push rod 6 in the fault trip gear is when guaranteeing the electrical equipment branch, closing in time the triping of contact mechanism, directly effect is taken place in indication piece 3 and snap close piece 5, carry out triping of indicating mechanism, reduced the link of message transmission, guaranteed the reliable indication of each required classification, can make electrical equipment automatically reset to normal operating conditions, indicate " normally " state of closing by hand, manual brake separating and " fault " state of fault trip like clockwork from the electric fault indicating status.Under normal condition, no matter electrical equipment is in manual brake separating or "on" position, all presents white in the window 10e of support 10.Under " fault " state, i.e. after the electrical equipment tripping operation, no matter operating grip 1 is in is closed a floodgate or the separating brake position, all presents redness in the window 10e of support 10, and indication piece 3 can not be subjected to the breaking speed of operating grip 1 and the present position influences and cause the mistake of indication piece to indicate.The composition reasonable in design of device for indicating failure of electric apparatus of the present invention, number of components is few, has reduced small product size, has beautified outward appearance, has reduced manufacturing cost.
