embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The one of the controlled dual air gap electromagnetic release of the utility model preferably implements structure as shown in Figure 1, and this magnetictrip is mainly used in low capacity breaker of plastic casing.
The utility model controlled dual air gap electromagnetic release comprises fixing yoke 2, armature 3, the conductive plate 1 be made up of conductor, dropout part, the draw bar 9 be made up of ferrimagnet, armature 3 is relative with the medial surface of yoke 2 and arrange rotationally, conductive plate 1 is arranged at below yoke 2, around conductive plate 1, magnetic field is produced when passing into alternating current, dropout part is arranged at above yoke 2, when armature 3 rotates under the effect of electromagnetic force, drive draw bar 9 action by dropout part.The controlled dual air gap electromagnetic release of the utility model also comprises middle baffle plate 11, middle baffle plate 11 is relative with the medial surface of yoke 2 and can arrange with moving horizontally, the upper end of middle baffle plate 11 is connected with rated current adjusting rod 10, when regulating rated current adjusting rod 10 along its axial motion, middle baffle plate 11 can with rated current adjusting rod 10 motion and move horizontally, thus change the initial position (namely change gap middle baffle plate 11 and yoke 2 between) of middle baffle plate 11 relative to yoke 2, namely the position of middle baffle plate 11 is limited (concrete structure as shown in Figure 5) by rated current adjusting rod 10.
The controlled dual air gap electromagnetic release of the utility model comprises another air gap formed between the medial surface of an air gap and middle baffle plate 11 and the yoke 2 formed between the medial surface of armature 3 and yoke 2, thus form two gap structure, the size of two air gap regulates respectively by rotation armature 3 and translation middle baffle plate 11, by regulating the initial position of armature 3 and middle baffle plate 11, the electric current of the multiple multiple of adjustable multiple rated current.
The controlled dual air gap electromagnetic release of the utility model also comprises reaction spring 4 for making the armature after rotation 3 reset and the drop-away current gear adjusting rod 7 for the initial position that limits armature 3, one end of reaction spring 4 is connected with base 12, the other end is connected with armature 3, and concrete structure as shown in Figure 4.Drop-away current gear adjusting rod 7 abuts against at the initial position of armature 3 and armature 3, and the position of drop-away current gear adjusting rod 7 regulates according to the initial position of required armature 3.When regulating drop-away current gear adjusting rod 7 along its axial motion, drop-away current gear adjusting rod 7 can drive the armature 3 abutted against with it to rotate, thus the gap reduced between armature 3 and yoke 2, thus reach the object of the initial position (namely changing the gap between armature 3 and yoke 2) regulating armature 3 relative to yoke 2.
Dropout part in the controlled dual air gap electromagnetic release of the utility model is for rotating dropout part, and it comprises the first rotation dropout part 5 and second and rotates dropout part 6, and its structure as shown in Figure 4.
The concrete adjustment process of the utility model controlled dual air gap electromagnetic release is as follows:
As shown in fig. 1, the axle that armature 3 can be fixing along the base 12 be made up of non-magnet material rotates, and controls its initial position, thus regulates the air gap between armature 3 and yoke 2, and then regulate drop-away current by electric current gear adjusting rod 7; Middle baffle plate 11 by rated current adjusting rod 10 limit levels shift position, thus can regulate the air gap between middle baffle plate 11 and armature 3.When conductive plate 1 passes through a certain size alternating current, around conductive plate 1, produce magnetic field, thus armature 3 is rotated along axle under the effect of electromagnetic force, drive draw bar 9 by rotating dropout part, thus drive outside snap close 8 to trip, complete trip action.
In sum, the controlled dual air gap electromagnetic release of the utility model, on the basis of traditional electrical magnetic release, with the addition of middle baffle plate, thus introduces two air gap.Adjustable pair of air gap comprises: fix the air gap between yoke and armature and pass through the adjustable initial air gap of rated current adjusting rod.Two air gaps are for the control of electric current, by following two kinds of methods: 1) regulate fixing initial size of gaps between yoke from armature to control different rated current, regulate the initial size of gaps between middle baffle plate and fixing yoke to regulate the multiple gear of drop-away current; 2) regulate fixing initial size of gaps between yoke and armature to regulate the gear of drop-away current, regulate the initial size of gaps between middle baffle plate and fixing yoke to control different rated current.By regulating the initial position of armature and middle baffle plate, the electric current of the multiple multiple of multiple rated current can be regulated, greatly extend the adjustable range of drop-away current.In dropout process, armature motion makes air gap reduce; Air gap between middle baffle plate and fixing yoke, regulates its initial air gap by external structure, and in dropout process, this air gap remains unchanged.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
