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.
