In the utility model, the functions of an electromagnetic tripper for short circuit current and an electromagnetic tripper for residual current can be achieved on one electromagnetic tripper, thereby not only saving the space, reducing the parts and lowering the cost, but also being favor for the modularization of a small-sized breaker.
Description
Technical field
The utility model relates to the low-voltage electrical apparatus field, is specifically related to a kind of magnetictrip of miniature circuit breaker.
Background technology
Miniature circuit breaker has overload, short circuit and aftercurrent action protecting function usually.Short-circuit protection function is realized thereby make armature motion and promote breaker mechanism turn-off current loop by comprising the magnetictrip induction that coil, armature, magnet yoke element etc. form and setting up magnetic field; The aftercurrent action protecting function is responded to residual current by zero sequence current mutual inductor, and when residual current during greater than set point, the action of residual current acting magnetictrip also promotes breaker mechanism turn-off current loop and realizes.
The magnetictrip of existing miniature circuit breaker is made up of two separate short circuit current action magnetictrip and residual current acting magnetictrips.It as application number 99206121.0 the disclosed technical scheme of patent, in space of the inner side expansion of the miniature circuit breaker of short circuit current action magnetictrip, the residual current acting magnetictrip is placed in this space, this structure has increased the volume of circuit breaker, wasted raw material, cost obviously improves.Another kind is 200420081810.6 the disclosed technical scheme of patent as application number; the coil sleeve of residual current acting magnetictrip is in the coil of short circuit current action magnetictrip; because two coils are to insert mutually with core; in actual use; two coil heatings superpose mutually; cause that easily the overheated potential winding that makes burns, and assembling inconvenience, be unfavorable for large-scale production.
The content of utility model
Above-mentioned shortcoming at existing magnetictrip, the applicant has carried out improving research, provide a kind of simple in structure, be easy to processing and manufacturing, production cost is low and properties of product are stable, has the combined electromagnetic release of short circuit current action magnetictrip and residual current acting magnetictrip function simultaneously.
The technical solution of the utility model is as follows:
A kind of combined electromagnetic release, coil rack is installed in the yoke, static iron core, moving iron core apparatus are in the container cavity of coil rack, current coil and potential winding are being installed on the coil rack or on the yoke, current coil, potential winding and are linked in the magnetic loop at the different tap positions of current coil, potential winding in same magnetic loop.
A further technical scheme is:
Described current coil, potential winding all are enclosed within on the coil rack.Described current coil is enclosed within static iron core one end, and described potential winding is enclosed within moving iron core one end; Perhaps described potential winding is enclosed within static iron core one end, and described current coil is enclosed within moving iron core one end.
Another further technical scheme is:
One of them is enclosed within described current coil, potential winding on the coil rack, and another is enclosed within on the yoke.Described current coil is enclosed within on the coil rack, and described potential winding is enclosed within on the yoke; Perhaps described potential winding is enclosed within on the coil rack, and described current coil is enclosed within on the yoke.
Useful technique effect of the present utility model is:
The utility model has the function of short circuit current action magnetictrip and residual current acting magnetictrip simultaneously on a magnetictrip, simple in structure, is easy to processing and manufacturing, can reduces production costs and the stable prod performance.Because current coil 4 and potential winding 5 shared magnetic circuit systems, the structure of magnetictrip is oversimplified more, reduces the part kind, has not only saved cost of material, has also saved processing cost, also helps the modularization of miniature circuit breaker.Assembly work is easier to be carried out because current coil 4 makes with potential winding 5 discrete layouts, and the product heat resistance is promoted greatly.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
As shown in Figure 1 and Figure 2, coil rack 6 of the present invention is installed in the yoke 1, static iron core 2, moving iron core 3 are installed in the container cavity of coil rack 6, current coil 4 and potential winding 5 are being installed on the coil rack 6 or on the yoke 1, current coil 4, potential winding 5 and are linked in the magnetic loop at the different tap positions of current coil 4, potential winding 5 in same magnetic loop.
Embodiment 1:
As shown in Figure 1 and Figure 2, current coil 4, potential winding 5 are enclosed within on the coil rack 6.Current coil 4 is enclosed within static iron core 2 one ends, and potential winding 5 is enclosed within moving iron core 3 one ends; Also can make potential winding 5 be enclosed within static iron core 2 one ends conversely, current coil 4 is enclosed within moving iron core 3 one ends.
Embodiment 2:
As shown in Figure 3, one in current coil 4, the potential winding 5 is enclosed within on the coil rack 6, and another is enclosed within on the yoke 1.Current coil 4 is enclosed within on the coil rack 6, and potential winding 5 is enclosed within on the yoke 1; Potential winding 5 is enclosed within on the coil rack 6, and current coil 4 is enclosed within on the yoke 1.
Operation principle of the present utility model is as follows: when the circuit operate as normal, there is not electric current to pass through in the potential winding 5, potential winding 5 does not produce excitation field, flow through the electric current that is not more than the circuit breaker rated current in the current coil 4, it is not enough so that moving iron core 3 actions that current coil 4 produces very little excitation field; When the big short circuit current of generation in the circuit made current coil 4 produce enough big excitation field, to the direction motion of static iron core 2, threaded off by pushing mechanism under the effect of this excitation field for moving iron core 3; When having enough big residual current to produce in the circuit, control circuit will be connected the circuit of potential winding 5, make potential winding 5 two ends load sufficiently high voltage, potential winding 5 produces enough big excitation field, make iron core 3 direction motion to static iron core 2 under the effect of this excitation field, pushing mechanism is threaded off.
The utility model is because current coil 4 and potential winding 5 shared one tunnel magnetic systems are simple in structure, and the part kind reduces, and has not only saved cost of material, has also saved processing cost.Assembly work is easier to be carried out because current coil 4 makes with potential winding 5 discrete layouts, and the product heat resistance is promoted greatly.
