Abstract
The utility model relates to the motor coil insulation technical field, and especially relates to a novel coil insulation composition comprising a plurality of wire gauge sets and a main insulation layer wrapped outside the wire gauge sets; an interturn insulation layer is arranged between adjacent wire gauge sets; each wire gauge is formed by combining a plurality of wire gauges in parallel. A single wire gauge of a large power motor is divided into a plurality of small wire gauges combined in parallel for usage; the small wire gauges are combined in parallel and a whole body is added with the interturn insulation layer, so motor slot fullness rate can be reduced, motor temperature rise is reduced, motor capacitor is increased, and the novel coil insulation composition is good in insulation effect; interturn fault is prevented in usage, thereby saving energy and reducing cost.
Description
Technical field
The utility model relates to insulating motor coil technical field, particularly a kind of new coil insulation system.
Background technology
At present, for electromechanics trade, insulation system is most important, directly affects capacity motor, temperature rise.The single wire gauge of high-voltage high-power motor generally all can be very large, in order to reduce eddy current loss and to be beneficial to end winding shaping, all single large wire gauge is made into several little wire gauge parallel connections and use, but so will reduce motor copper factor, electric machine temperature rise is raise, cause capacity motor to reduce.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of new coil insulation system that improves motor copper factor, effectively reduces electric machine temperature rise, increase capacity motor.
According to design provided by the utility model, a kind of new coil insulation system, comprise some wire gauge groups and the main insulating layer that is wrapped in wire gauge group periphery, between described adjacent wire gauge group, be provided with turn-to-turn insulation layer, described each wire gauge group is formed by many wire gauge parallel combinations.
According to above-mentioned new coil insulation system, described main insulating layer material is low-resistance belt, or is mica tape.
According to above-mentioned new coil insulation system, described turn-to-turn insulation layer material is double glass fiber, or is mica tape.
The beneficial effect of a kind of new coil insulation system of the utility model:
The single wire gauge of heavy-duty motor is divided into many in parallel uses of little wire gauge by the utility model, after little wire gauge parallel connection, entirety adds turn-to-turn insulation layer, so not only reduce motor copper factor, electric machine temperature rise is reduced, increase capacity motor, and insulation effect is good, avoids occurring in use procedure turn-to-turn fault, energy savings, reduces costs.
accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
embodiment
Number in the figure 10 represents wire gauge, and label 11 represents turn-to-turn insulation layer, and label 12 represents main insulating layer.
Below in conjunction with accompanying drawing and technical scheme, the utility model is described in further detail.
Shown in Figure 1, a kind of new coil insulation system, comprise some wire gauge groups and the main insulating layer 12 that is wrapped in wire gauge group periphery, described each wire gauge group is formed by many wire gauges 10 parallel combinations, between described adjacent wire gauge group, be provided with turn-to-turn insulation layer 11, between the many wire gauges 10 in wire gauge group, turn-to-turn insulation layer be not set.
Described main insulating layer 12 materials are low-resistance belt, or are mica tape.
Described turn-to-turn insulation layer 11 material are double glass fiber, or are mica tape.
The single wire gauge of heavy-duty motor is divided into many in parallel uses of little wire gauge by the utility model, between many little wire gauges, turn-to-turn insulation is not set, the entirety of the wire gauge group forming after little wire gauge parallel connection adds turn-to-turn insulation layer, so not only reduce motor copper factor, electric machine temperature rise is reduced, increase capacity motor, and insulation effect is good, avoid occurring turn-to-turn fault in use procedure, energy savings, reduces costs.
The utility model is not limited to above-mentioned embodiment, and those skilled in the art also can make multiple variation accordingly, but any and the utility model are equal to or similarly change and all should be encompassed in the scope of the utility model claim.
