Description
Technical field
The invention belongs to technical field of generators, particularly relate to a kind of method for gradually inserting coil of loop-type coils of high-voltage motor.
Background technology
At present, along with the increase of capacity motor, voltage and current is also along with increase, thereby the electric machine winding group just produced hard coiling group, its coil be shaped as " circle formula (shaped as frame) " and two kinds of form-wound coils of bar line stick.Bar line stick is single rolling off the production line when rolling off the production line in stator coring groove, so roll off the production line than being easier to, " circle formula (shaped as frame) " coil then rolls off the production line just cumbersome, all adopts " taking the upper hand again " (or claiming to turn over circle limit, upset circle limit) offline mode when it rolls off the production line.
So-called " taking the upper hand again " inserting-coil process is: from the coil of first segment distance, just at the bottom of lower floor's limit embedded groove, the limit, upper strata is the embedded groove internal upper part also.When closing up to the end down, when again the coil electricity of first segment distance being heated to 70-80 ℃, under hot state, " taking the upper hand again " extracted in the limit, upper strata in groove, about 90 ° of angles of overturning, the relative lower floor in limit, upper strata limit, this moment, straight line portion was indeformable, only allow nose deformation, the upper ring edge of slinging.Avoid the notch space on the lower floor circle limit of last pitch like this, trench bottom is arrived on the lower floor of the coil of last pitch circle limit down, and then the limit, upper strata of whole coils of the initial first segment distance 90 ° of normal shapes that are recovered to original coil that overturn again, to the position, upper strata of groove, finished the overall process that rolls off the production line so down.
From the whole overall process that rolls off the production line and close up, can see whole coils of initial first segment distance, for closing up of coil is 90 ° of degree of " receiving handle " twice upset angle.Why coil can be implemented in nose portion so big variation, and key is that the main insulation material of coil is thermoplastic, and when coil was heated to 80-90 ℃, whole winding can deliquescing.Make nose that so big distortion be arranged certain twice, the main insulation electrical strength is had great damage,, also have to do like this because motor will be finished down line process.

Embodiment
For further understanding technology contents of the present invention, characteristics and effect, enumerate following example now, and be described with reference to the accompanying drawings as follows:
See also accompanying drawing 1 and Fig. 2.
Method for gradually inserting coil of loop-type coils of high-voltage motor, the key of wire insertion technology have been handle and have received two links.Play that the position, upper strata of first segment distance will be created conditions in the lower floor's embedded groove for a pitch receiving, and rise the limit is enclosed by the lower floor of first segment distance, embedded groove makes down the coil of several pitches carry out regular rule more than interior again.
For this reason, made circle limit in the upper strata of first pitch coil has been raised.And the distance of raising is as the criterion so that receipts are entered coil lower floor circle limit in the groove easily.
Be as the criterion with interior with the strain that " distortion " that coil was taken place is limited in coil insulation and play the degree of depth that the lower floor of first segment distance circle limit is entered in the groove.
Subsequently, the coil of second pitch, the coil of the 3rd pitch ... employing (coil of each pitch is an one-level) ladder is step by step fallen progressively and is goed deep in the groove, carries out cycloid like this, through the transition of 3-4 pitch, but formal down line process so just can be carried out also with regard at the bottom of the embedded groove in the lower floor of coil circle limit.
When closing up, receive the coil lower floor limit of pitch is entered the spacing that is pre-existing between limit, upper strata and the internal diameter unshakable in one's determination in the groove by means of rising, Here it is gradually inserting.
In a word, gradually inserting be utilized and subsequent the coil of several pitches the method in the groove of entering that falls progressively step by step, through several transition segments apart from after, coil can formally roll off the production line.Simultaneously, rise the gap that exists between the bottom surface, limit, upper strata of coil and the inside diameter surface unshakable in one's determination caused again to receive coil lower floor circle limit is entered the interior necessary spacing of groove.
The gradually inserting concrete steps: it is some to get insulation filler strip 2, is overlapped into a square column type, uses the strap tighten, and it is long that its length equals pitch, highly equals 1/2 groove depth, totally 2.
Then, begin several coils 1 of first segment distance down, the limit, upper strata of these several coils 1, with above-mentioned square column cushion block well with coil upper strata pad.
In the embedded groove, the degree of depth is not to be as the criterion painstakingly between the cushion block of limit, upper strata gently on the lower floor limit, and (seeing Fig. 1, Fig. 2) can embed groove depth 1/4 usually.
The coil of second pitch, in the embedded groove, the limit, upper strata rides on the lower floor limit of first segment distance successively, and it is 1/2 of groove depth that groove depth is gone on the limit by lower floor.
The 3rd pitch in like manner, the limit, upper strata rides on the lower floor limit of second pitch, groove is gone in the limit by lower floor, the degree of depth is 3/4 of a groove depth.
Bottom land under the embedding can be finished in the lower floor limit of the 4th pitch.
Following pitch begins normally to roll off the production line.During to a last pitch coil, square column cushion block 3 is extracted out.This moment first pitch coil the limit, upper strata, with the spatial altitude of iron core be 1/2 groove depth, can be with the lower floor limit of the last pitch coil that puts in less than 1/2 groove depth, its space length equals a pitch.Therefore, also fully can following last coil (see figure 2) of finishing last pitch.
Receive at last having knocked gently successively coil with rubber hammer to the direction of first segment distance, do not exert great efforts and can finish receipts program since the coil of the 4th pitch, the layer insulation filler strip the time be encased inside in advance as much as possible.
Should divide several transition segments at the bottom of the embedded groove as for rising, decide according to the depth of groove, the size of pole span coil.Ordinary circumstance is that groove is dark more, needs the pitch number of transition many more at the bottom of the embedded groove, and this is that the limit deformation that just can guarantee coil is in the scope of minimum because only so.Also have a factor to be: pole span is more little, needs the pitch number of transition many more at the bottom of the embedded groove, and this is that the central angle of coil is more little because pole span is more little, allows the size of distortion more little.
In sum, this inserting method rolls off the production line much smaller to the damage of coil insulation than taking the upper hand again to the damage of coil insulation, because it has avoided " taking the upper hand again ", " handle falls " turns over for twice and turn round the damage that coil insulation causes.
