Abstract
The utility model relates to a single-sided epoxy dry polyster film powder mica tape, including a mica paper (1), strengthening material (3) and epoxy bond (2) connecting the mica paper (1) and the strengthening material (3). The utility model has the beneficial effects of meeting the requirements of loop manufacturing technology, speeding up the manufacture speed, lowering cost, high bond strength, no delamination and no powder fall. Because the polyster film is used as the strengthening material, insulation performance is improved greatly and insulation thickness is thinner; the motor size and cost are reduced.
Description
Technical field
The utility model relates to a kind of mica tape, relates in particular to the structure of this mica tape.
Background technology
Ac high-voltage motor main insulation has several systems such as many rubber powders mica tape die stamping insulation, middle rubber powder mica tape VPI insulation and low resin mica tape VPI insulation in the prior art.From combination property and long term growth, low resin mica tape VPI insulation is undoubtedly the developing direction of high-voltage motor insulated manufacturing technology.
Compare with preceding two kinds of insulation systems, mica content in the low resin mica tape VPI insulation significantly improves, no air gap in the insulation, overall performance is good, helps improving the electric property of insulation, corona resistance and anti-electric life, thereby improved technical indicator, service life and the operational reliability of motor, simplified the coil manufacturing process greatly simultaneously, not only can shorten the production cycle, reduce manufacturing cost, and help improving the coil insulation quality.
In the former development type, low resin mica tape is extremely unstable, flies problems such as powder, layering, can not satisfy mechanical wrapped coil technological requirement, can't produce in batches, does not satisfy the demand of electromechanics trade.
Summary of the invention
The utility model technical issues that need to address have provided a kind of epoxy little-glue single-face polyester film powder mica tape, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: mica paper; Also comprise: supporting material; Connect by the modified epoxy adhesive between described mica paper and the supporting material.
Compared with prior art, the beneficial effects of the utility model are: can satisfy the coil manufacturing process, faster production reduces cost, and the adhesion strength height is not stratified, not the epoxy little-glue mica tape of dry linting.Because adopting polyester film is supporting material, has improved insulation property greatly, makes the insulation thickness attenuate become possibility.Reduce the size of motor, reduced cost.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As seen from Figure 1: the utility model comprises: mica paper 1; Also comprise: supporting material 3; Connect by modified epoxy adhesive 2 between described mica paper 1 and the supporting material 3;
Described mica paper 1 is big scale mica paper;
Described supporting material 3 is the very high polyester films of single face dielectric strength.
The utility model is made up of supporting material, modified epoxy adhesive and big scale mica paper.Through compound, cure, rolling, cutting form.
Supporting material is a polyester film.The polyester film dielectric breakdown strength is very high, insulation thickness that can the attenuate coil after using.Because adopt the modified epoxy adhesive, glue content is lower than 11%, the mica tape softness, dry linting not, the adhesion strength height, not stratified.It is wrapped to be suitable for high speed, but high volume applications is wrapped in the coil of high-voltage motor, greatly attenuate insulation thickness, improved the insulation quality of coil, shortened the cycle, greatly reduce production cost.
The utility model is applicable to motor, wind-driven generator coil, lead-in wire and end lapped insulation.Adopt big scale mica tape to make mica tape have better permeability, improved the overall performance of motor coil, improved electric, anti-corona, anti-electric life.Epoxy binder modified have a very high adhesive strength, with existing insulated impregnating resin higher intermiscibility arranged again simultaneously, and low resin mica tape is produced in batches becomes possibility.
Claims (3)
1. an epoxy little-glue single-face polyester film powder mica tape comprises: mica paper (1); It is characterized in that: also comprise: supporting material (3); Connect by modified epoxy adhesive (2) between described mica paper (1) and the supporting material (3).
2. epoxy little-glue single-face polyester film powder mica tape according to claim 1 is characterized in that: described mica paper (1) is big scale mica paper.
3. epoxy little-glue single-face polyester film powder mica tape according to claim 1 and 2 is characterized in that: described supporting material (3) is the very high polyester film of single face dielectric strength.
