The present utility model provides a low voltage circuit breaker overcurrent release that has advantages of convenient assembly, small footprint, variable combination of coil turns and wire size may generate magnetic field required by circuit breaker different for action.
Description
(1) technical field
The utility model relates to a kind of low-voltage circuit breaker overcurrent trip.
(2) background technology
The overcurrent trip of low-voltage circuit breaker, generally comprise Thermomagnetic type, electronic type, the overcurrent trip of Thermomagnetic type comprises bimetal leaf, heater element, coil, iron core, yoke, described bimetal leaf connects the actuator of low-voltage circuit breaker, described heater element connects the operating current end, and described iron core penetrates in the coil, is provided with the gap between described coil and the bimetal leaf, described heater element is fixedlyed connected with bimetal leaf, and described yoke cooperates with described iron core.Bimetal leaf and heater element are riveted together, and iron core and coil and bimetal leaf link together.The problem that exists: 1, the space is big, the assembly manipulation trouble; 2, in release, iron core and coil ratio are easier to damage, if when iron core or coil damage, need to change whole release, use cost height; 3, coil turn malleable not can not produce action according to different requirement of circuit breaker, generally can only be suitable for the circuit breaker of certain specific model.
(3) summary of the invention
Existing low-voltage circuit breaker overcurrent trip assembly manipulation trouble, space are big in order to overcome, the coil turn deficiency of malleable not, and the utility model provides a kind of simple and convenient, low-voltage circuit breaker overcurrent trip little, that can change coil turn that takes up space that assembles.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of low-voltage circuit breaker overcurrent trip, comprise bimetal leaf, heater element, coil, iron core, yoke, described bimetal leaf connects the actuator of low-voltage circuit breaker, described heater element connects the operating current end, described iron core penetrates in the coil, is provided with the gap between described coil and the bimetal leaf, and described heater element is fixedlyed connected with bimetal leaf, described yoke cooperates with described iron core, and described coil is connected by dismountable securing member with described yoke.
Further, described iron core axial aperture, perforate on the described bimetal leaf, perforate on the described heater element, the perforate that described securing member passes iron core endoporus, bimetal leaf and heater element successively is connected with yoke.
Described iron core one end is connected with coil, and the other end is fixedlyed connected with back-up ring, is provided with the gap between described back-up ring and the described bimetal leaf.
Further again, described securing member is a set bolt.
Described yoke is fixedlyed connected with described heater element.
Described yoke is provided with connecting rod, and described heater element, bimetal leaf are provided with riveted holes, and described connecting rod passes two riveted holes and riveted joint.
Its operation principle is: coil and iron core are formed a magnetic system, and the magnetic field that is produced is used to trigger the action of low-voltage circuit breaker actuator, and the end of bimetal leaf connects this actuator; Coil generally is entwined by the copper paint envelope curve; Iron core is generally made by ferrous material, can be changed the magnetic field of combination results low-voltage circuit breaker different needs according to coil turn and line footpath, requires to produce a trigger action according to circuit breaker.
Heater element produces heat energy under the effect of electric current, bimetal leaf is extremely responsive to heat energy, the heat effect of heater element can promote bimetal leaf and bend, thereby promote actuator's action of low-voltage circuit breaker, keep certain clearance between coil and the iron core, guarantee the activity interval of bimetal leaf, avoid coil to hinder the action of bimetal leaf, according to the different current requirements of circuit breaker, can select the heater element and the varying sensitivity of bimetal leaf to be together to form the long delay tripping system of different requirements.
Removably be connected between bimetal leaf and the coil, it is simple and convenient to assemble whole release, only need by securing member with coil stationary on yoke; During dismounting, only need removal of fastener to get final product, change the number of turn of coil and the variation combination in line footpath, can produce the different magnetic fields that require of circuit breaker to produce action, applicable to the circuit breaker of different model.
The beneficial effects of the utility model mainly show: 1, assembling is simple and convenient; 2, the space is little; 3, pull down coil after, can adjust coil turn easily; If 4 coils or iron core damage, only need that broken parts is removed replacing and get final product, can less use cost.
