Description
Technical field
The present invention relates to hydrogenerator, and in particular to a kind of hydrogenerator pole(cell) insulation box preparation method, insulation booth
For the insulation between pole coil and pole core.
Background technology
Pole(cell) insulation refers to the insulation between pole coil and pole core.In, low capacity water-wheel generator magnetic pole pole body it is exhausted
Bag consolidated structures are scalded using the direct mopping of epoxy phenol aldehyde glass embryo cloth more than edge.In, the magnetic pole pole body of large capacity hydroelectric generator it is exhausted
Use glued construction more edge, bonded on iron core, pole(cell) insulation is highly highly smaller 1~4 millimeter than pole body unshakable in one's determination, its end
For epoxy phenolic glass cloth rolled-up stock, and straight line portion is machined to the epoxy phenol aldehyde glass cloth laminated board of type.Bag is scalded in traditional mopping
Consolidated structures have as a drawback that：1）As shown in figure 1, due to regardless of straight line portion and end, every layer of epoxy phenolic glass cloth
Length will be with pole core pole body girth almost, and centre does not allow splicing, and stock utilization is relatively low；2）Scald every layer of stitching portion of bag
When epoxy phenolic glass cloth is tensed, gap 5 is otherwise easily formed between hot pole(cell) insulation and pole core 4, reduction is exhausted
Edge effect, operation requires high, and difficulty is big, and cost of manufacture is high.During using conventional adhesive structure, as shown in Fig. 2 the epoxy of its end
Phenol aldehyde glass cloth rolled-up stock needs to use cavity plate and the secondary mould 6 of punch-pin two during actual fabrication, is suppressed by cavity plate and punch-pin
Form, because the rolled-up stock versatility is not strong, and needs to use heating furnace and be heating and curing, so fabrication cycle is long, production cost
It is high.
The content of the invention
Have the shortcomings that fabrication cycle length, production cost are high present invention is generally directed to traditional insulation booth production method, send out
Understand a kind of hydrogenerator pole(cell) insulation box preparation method, insulation booth divide into straight line portion and overhang insulation box part, directly
Formed between line part and overhang insulation box using inclined-plane overlap joint, meanwhile, the making of overhang insulation box no longer needs to use mould,
But epoxy phenol aldehyde glass embryo cloth is successively superimposed boiling hot bag and formed, time-consuming short, cost is low.
The above-mentioned technical problem of the present invention is carried out by the following technical programs：A kind of hydrogenerator pole body is exhausted
Edge box preparation method, pole(cell) insulation box by both sides straight line portion and two ends overhang insulation box overlap joint constitute, straight line portion with
The connecting portion of overhang insulation box is arranged to the two of the overlap joint inclined-plane being mutually matched, the i.e. two ends of straight line portion and overhang insulation box
End is arranged to angle of inclination identical inclined-plane, using viscous between the overlap joint inclined-plane of straight line portion and the overlap joint inclined-plane of overhang insulation box
Mixture is bonded.
If described overhang insulation box is successively covered by dried layer epoxy phenol aldehyde glass embryo cloth and is formed by stacking, its making step bag
Include：
A, in magnetic pole pole body surface brush ring oxygen phenol glue, first layer epoxy phenol aldehyde glass embryo cloth is coated on magnetic pole pole body
On, this layer of epoxy phenol aldehyde glass embryo cloth is heated with boiling hot bag equipment, pressed；
B, the outside that second layer epoxy phenol aldehyde glass embryo cloth is covered in first layer epoxy phenol aldehyde glass embryo cloth, are set with boiling hot bag
It is standby that second layer epoxy phenol aldehyde glass embryo cloth is heated, pressed；
C, in the way of step B, if remaining dried layer epoxy phenol aldehyde glass embryo cloth is sequentially coated on into last layer epoxy phenol
The outside of aldehyde glass embryo cloth, often covers one layer of epoxy phenol aldehyde glass embryo cloth, will be with boiling hot bag equipment to this layer of epoxy phenol aldehyde glass
Embryo cloth is heated, pressed；
D, scald and wrap one layer of epoxy phenol aldehyde glass embryo cloth of outermost after, if dried layer epoxy phenol aldehyde glass embryo cloth mutually glue it is boiling hot
Overhang insulation box semi-finished product are formed, overhang insulation box semi-finished product and magnetic pole pole body are bound with bandage；
From first layer epoxy phenol aldehyde glass embryo cloth to one layer of epoxy phenol aldehyde glass embryo cloth of outermost, epoxy phenol aldehyde glass embryo cloth
Length be gradually reduced, the two ends of overhang insulation box is formed inclined overlap joint inclined-plane, overlap joint inclined-plane now is rougher, its chi
The very little overlap joint that can also also meet is required, so needing follow-up finishing；
E, solidification：Cooled and solidified under natural conditions, general solidification temperature is room temperature；
F, deburring：Complete after solidification, remove bandage, deburring is carried out to overlap joint inclined-plane with cutter.
Preferably, the boiling hot bag equipment wraps special electric iron or boiling hot bag electric iron special to scald, scalding bag temperature is
175 DEG C~190 DEG C.
Preferably, the hardening time is 4~7 minutes.
Preferably, the insulation booth thickness is 3 millimeters, the length on overlap joint inclined-plane is 70 millimeters, overlaps the end points on inclined-plane
0.5 millimeter of thickness.
Preferably, the overhang insulation box is formed by stacking by 6~12 layers of epoxy phenol aldehyde glass embryo cloth.
Preferably, described adhesive is made up of epoxy resin, polyamide according to proportioning 100: 70.
Preferably, the pole(cell) insulation box is made up of the straight line portion of both sides and the overhang insulation box overlap joint at two ends, often
One pole(cell) insulation box is provided with four inclined-plane overlapped points.
In summary, the present invention has the following advantages that compared with prior art：
Insulation booth divide into straight line portion and overhang insulation box part by the present invention, between straight line portion and overhang insulation box
Formed using inclined-plane overlap joint, process is simpler, is easy to produce and operates, and improves the utilization rate of material；The end of the present invention is exhausted
No longer need to use mould in the manufacturing process of edge box, save die cost.
The making of overhang insulation box of the present invention is directly successively to be superimposed epoxy phenol aldehyde glass embryo cloth to scald bag in magnetic pole pole body
On, it is ensured that the insulation booth of shaping can be brought into close contact with magnetic pole pole body, and insulation effect is good.
In the manufacturing process of overhang insulation box of the present invention, glass fabric of epoxy resin is directly overlayed on magnetic pole pole body,
So the amount of being body makes, compared with the production method of molding type, mode of the invention, which makes, can avoid magnetic pole pole body and insulation
Box unmatched problem in specification.
