Description
Technical field
The invention belongs to dynamo-electric manufacture field, particularly a kind of trip gear adjustable for the protection class in breaker of plastic casing.
Background technology
On market, breaker of plastic casing is when short-circuit protection, and the snap action protection of thermo magnetic trip release Direct Action Type is moved iron core by the big current that short circuit produces by the magnetic attraction that coil produces and driven draw bar to realize protection of threading off.Usual stage clip props up racking iron core in this device, keeps air gap.Circuit breaker functional requirement: release can will be threaded off within the scope of setting current, mates the rated current of different size by the stage clip changing different size.All very high to the required precision of the magnetic force of each pole of product, spring like this, due to whole Pyromagnetic release be assembled after verify again, if there is substandard product (early dynamic or motionless), Field adjustment cannot be carried out to product, can only disassemble product, verify after changing spring, this have impact on production efficiency in process of production greatly, causes the waste of unnecessary human and material resources again.
Summary of the invention
The object of this invention is to provide a kind of simple for structure in breaker of plastic casing, thread off reliable and the trip gear that multiple current class regulates can be realized.
For the trip gear that the protection class in breaker of plastic casing is adjustable, this trip gear comprises: extension spring, slidable adjustment button, supporter, adjustment draw bar, adjusting screw(rod), nut, sleeve, dynamic iron core, magnetic coil, static iron core, yoke, pedestal, stage clip, dropout part, dropout draw bar; One end of described extension spring is connected with adjusting screw(rod), and the other end is connected with adjustment draw bar; One end of slidable adjustment button is connected with adjustment draw bar, and the other end is installed in the relevant position of supporter; Described dynamic iron core is threaded connection by adjusting screw(rod) and sleeve and forms, and one end of adjusting screw(rod) is connected with extension spring, and the other end is connected with bush whorl; Nut thread is set in adjusting screw(rod) one end near extension spring; Described magnetic coil, static iron core are positioned at the rectangular chamber of yoke and pedestal formation, and static iron core is fixed on immediately below dynamic iron core; Stage clip is installed on dropout part, and one end of dropout draw bar is engaged with dropout part, and other end thread set, on adjusting screw(rod), is positioned at the below of nut;
In dropout process, different protection class can, by regulating slidable adjustment button, make adjustment draw bar rotate the length regulating extension spring, and the current class gear realizing drop-away current regulates; When there being short circuit current by release, the magnetic field suction that magnetic coil produces moves iron core, dynamic iron core is rotated down motion makes extension spring stretch, and drive dropout draw bar to rotate by nut, after dropout draw bar rotates, snap fit is thrown off, dropout part rotates under the effect of stage clip bounce, realizes the trip action of breaker body.
Not only structure is simple for trip gear of the present invention, dropout is reliable, but also achieves the adjustable function of multiple current class, substantially increases production efficiency and verification efficiency.

Fig. 2 is the front view of release apparatus of the present invention;
Fig. 3 is the left view of release apparatus of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
As shown in Figure 1, Figure 2, Figure 3 shows; breaker of plastic casing can be divided into 1 ~ 4 pole as required, and each pole is all provided with trip gear, the problem that the present invention finds in actual use according to breaker of plastic casing; devise a kind of new trip gear, this trip gear is applicable to different protection class.For the trip gear that the protection class in breaker of plastic casing is adjustable, this device comprises: extension spring 1, slidable adjustment button 2, supporter 3, adjustment draw bar 4, adjusting screw(rod) 5, nut 6, sleeve 7, dynamic iron core 8, magnetic coil 9, static iron core 10, yoke 11, pedestal 12, stage clip 13, dropout part 14, dropout draw bar 15.One end of extension spring 1 is connected with adjusting screw(rod) 5, and the other end is connected with adjustment draw bar 4; One end of slidable adjustment button 2 is connected with adjustment draw bar 4, and the other end is installed in the relevant position of supporter 3.Dynamic iron core 8 is threaded connection by adjusting screw(rod) 5 and sleeve 7 and forms, and one end of adjusting screw(rod) 5 is connected with extension spring 1, and the other end is threaded with sleeve 7.Nut 6 thread set is in one end near extension spring 1 of adjusting screw(rod) 5.Magnetic coil 9, static iron core 10 are positioned at the rectangular chamber of yoke 11 and pedestal 12 formation, and static iron core 10 is fixed on immediately below dynamic iron core 8.Stage clip 13 is installed on dropout part 14, and one end of dropout draw bar 15 is engaged with dropout part 14, and other end thread set, on adjusting screw(rod) 5, is positioned at the below of nut 6.
When there being short circuit current by release, the magnetic field suction that magnetic coil 9 produces moves iron core 8, dynamic iron core 8 is rotated down motion makes extension spring 1 stretch, and drive dropout draw bar 15 to rotate by nut 6, dropout draw bar 15 rotates rear snap fit and throws off, dropout part 14 rotates under the effect of stage clip 13 bounce, realizes the trip action of breaker body.In dropout process, different protection class by regulating slidable adjustment button 2, can make adjustment draw bar 4 rotate the length regulating extension spring 1, changing counter-force size, and the current class gear so also just achieving drop-away current regulates.When magnetic coil 9 is by after electric current, can suction be produced between static iron core 10 and dynamic iron core 8, thus iron core 8 is moved downward, complete reset.Adjusting screw(rod) 5 can change the amount of tension of distance between dynamic iron core 8 and static iron core 10 and spring 1, thus changes the fine setting that dynamic suction between iron core 8 and static iron core 10 realizes the current protection characteristic of single gear.
Trip gear of the present invention regulates the rotation of draw bar 4 to regulate the initial tension of the extension spring 1 be connected with dynamic iron core 8 to realize the fine setting of drop-away current by slidable adjustment button on release panel 2 and current class gear adjusts.Trip gear of the present invention not only structure is ingenious, simple, and greatly can also improve batch production efficiency and verification efficiency.
