Description
Technical field
The utility model relates to a kind of breaker thermal magnetictrip.
Background technology
Thermoelectricity magnetic release is a most key action executing element in circuit breaker, and existing thermoelectricity magnetic release is formed by support, armature, yoke, heater element, the two gold of heat, spring, axle and rivet combination conventionally.General is all in the centre of armature, to wear a rotation axis, the below of armature and the yoke being fixed on support leave certain electromagnetism gap by torsion spring, the top of armature connects the tripping mechanism that can make circuit breaker tripping, and the application point of tripping mechanism and yoke direction are reverse, while having Short-Circuit High Current to occur in loop, in yoke, produce loop current magnetic field, the constraint that armature lower end overcomes torsion spring active force when magnetic field the is greater than set point moving axis that rotates rotates to yoke adhesive direction, thereby the upper end of armature promotes circuit breaker, de-mouth mechanism makes breaker open operation, thereby cut off the electricity supply.
But, also there is certain problem in above-mentioned tripper structure: the torque of torsion spring will be changed according to product current specification size, and shape and size are substantially close, in circuit breaker actual production, specification kind is many especially, in stock, similar torsion spring part is extremely easily obscured, and causes a lot of troubles of production management.
On the other hand, because the field of employment of circuit breaker is more and more wider, a lot of users have proposed the product that same shell dimension will be done less current specification, and conventional way only has the heating resistive element of replacing and release torsion spring to realize, but effect is undesirable.
Summary of the invention
The shortcomings such as the torsion spring torque replacing of existing thermoelectricity magnetic release structure existence bothers in order to overcome, the effect of little current specification product is undesirable, the utility model provides a kind of breaker thermal magnetictrip that torsion spring is adjusted the breaker thermal electromagnetic release mechanism of torsion, increase heating resistor coil, applicable multiple current specification of being convenient to.
The technical solution adopted in the utility model is:
Breaker thermal magnetictrip, comprise support, rivet, armature, rotation axis, heater element, torsion spring, the two gold of heat and yoke, the two gold of described heat, heater element and yoke are hinged on support one side, the position that the opposite side of support is relative with yoke is provided with described armature, described heater element, the two gold of heat are riveted by described rivet and described support respectively, it is characterized in that: also comprise insulating trip and resistance coil, the middle part, both sides of described support is provided with the rotation axis can be through torsion spring and armature the inclination U-lag rotatablely moving mouth is provided; Described two sides, support upper end are provided with many groups and for torsion spring, change the spring hanging groove mouth of torque magnitude, the spring arm of the described torsion spring left and right sides is affiliated on described spring hanging groove mouth, by changing two spring arms, at the front and back position of spring hanging groove mouth, regulates the torsion of hanging spring; On described heater element, be welded with described resistance coil, described resistance coil is longitudinally wound in described yoke, the installation direction of described yoke is longitudinal and parallel with the installation direction of heater element, is provided with described insulating trip between described resistance coil and yoke.
Further, the opening part of the breach direction of described U-lag mouth is higher than the height of U-lag mouth bottom centre's point.
Further, the other end of described resistance coil welds by copper litz wire and terminal block.
The beneficial effects of the utility model are embodied in:
1, this breaker thermal magnetictrip that the utility model provides, owing to adopting opening inclination U-shaped notch design at support and shaft connection place, makes to assemble convenient; And the opening part of inclination U-lag mouth, higher than U-lag mouth bottom, can guarantee that axle can not skid off laterally under torsion spring active force;
2, this breaker thermal magnetictrip that the utility model provides, owing to being provided with many group spring hanging groove mouths on support, by adjusting two extension spring arms, at the front and back position of spring hanging groove mouth, regulate the torsion of torsion spring, can make a kind of specification torsion spring tackle multiple current specification circuit breaker, simplify manufacturing process, saved the cost in production management;
3, this breaker thermal magnetictrip that the utility model provides, owing to having increased resistance coil in yoke, be equal to and increased loop number of ampere turns, can effectively strengthen magnetic field, loop, can tackle the little current specification product that user proposes according to different electricity consumption occasions, and because coil is longitudinally wound around, take up room minimum.
