Fig. 2 is the shunt release schematic perspective view that is used for breaker with double breaks and plastic case;
Fig. 3 is the shunt release breakdown schematic perspective view that is used for breaker with double breaks and plastic case.
Among the figure: 1 armature, 2 lids, 3 hooks, 4 bases, 5 supports, 6 springs, 7 sensitive switches, 8 push rods, 9 second springs, 10 yokes, 11 coils, 12 screws, 13 iron cores, 14,15 round platforms, 16 holes.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, Fig. 2, Fig. 3, a kind of shunt release that is used for breaker with double breaks and plastic case comprises base 4, lid 2, coil 11, yoke 10, iron core 13, armature 1, support 5, push rod 8, spring 6, second spring 9, hook 3, sensitive switch 7, axle 14.The hole at coil 11 centers is passed iron core 13 and is installed in the yoke 10, and iron core 13 and support 5 riveted and fixed are on yoke 10, and yoke 10 and support 5 are arranged in the base 4, and yoke 10 is fixed on the base 4 through screw 12 and packing ring.Armature 1 is located in the hole at coil 11 centers and can be free to slide, and armature 1 neck is stuck in the U type frid of hook 3; Spring 6 is sleeved on the armature 1, and spring 6 two ends are the U type frid and support 5 bottoms of butt hook 3 respectively, and armature 1 can be resetted towards the direction that deviates from iron core 13 under the effect of spring 6.Hook 3 is located in base 4 grooves, and the U type frid of hook 3 one ends is connected with armature 1, and the other end is connected with the draw bar of circuit breaker transmission mechanism; Hook 3 can under the drive of armature 1 in base 4 linear slide, thereby the pulling draw bar.
Described sensitive switch 7 vertically is installed in base 4 bottoms and places in the base 4.Second spring 9 is sleeved on the axle 14 of base 4 bottoms, and the axle 14 of base 4 bottoms is equipped with push rod 8, and push rod 8 can rotate around axle 14, and second spring 9 is held push rod 8 rotates counterclockwise push rod 8.After rotateing in place, can touch by push rod 8 Action Button of sensitive switch 7.
11 lead-out wires of the coil of shunt release connect the control power supply, and coil 11 another root lead-out wires connect sensitive switch 7 normal-closed ends, and sensitive switch 7 common terminal are connected with the control power supply.
The course of work that the utility model is used for the shunt release of breaker with double breaks and plastic case is:
Shunt release of the present utility model is installed in the breaker of plastic casing.When circuit breaker was in "on" position, push rod 8 was leaning against under the effect of second spring 9 on the guide vane end stop of base 4, and push rod 8 is not pushed down the Action Button of sensitive switch 7.When the disjunction of needs far distance controlled circuit breaker, after shunt release is received extraneous control circuit signal, make its home loop conducting, coil 11 energisings.The electromagnetic force that coil 11 produces makes armature 1 by iron core 13 moments attraction, and armature 1 drives hook 3, and the reaction force that makes hook 3 overcome spring 6 slides to iron core 13 directions.Thereby make hook 3 pulling circuit breaker draw bars, make circuit breaker tripping, mechanism disconnects.
After mechanism disconnects, the circuit breaker main shaft rotates, main shaft withstands push rod 8, the active force that makes push rod 8 overcome second spring 9 clockwise rotates, after rotateing in place, push rod 8 pushes down the Action Button of sensitive switch 7, sensitive switch 7 works and disconnects coil 11 electric currents, has avoided coil 11 owing to long-time galvanization burns.So just realize the disjunction of far distance controlled circuit breaker.
The volume of an embodiment of shunt release that the utility model is used for breaker with double breaks and plastic case is little, and its length * wide * height is 34.5 * 18.3 * 28.2 (millimeters
3), satisfy the requirement of relative breaker, and easy for installation, stable performance, noise is low, and is highly sensitive, and shunted exciter tripping is reliable, can exchange or the direct current use.
