Abstract
The invention provides a safety-increased type motor anticorona structure, which comprises a coil straight line part, an iron core and a coil end part, wherein polyimide film-fluorine 46 covered flat copper wires are adopted for coil interturn insulation, polyimide film single-side reinforced little-glue mica tapes and glass fiber single-side reinforced little-glue mica tapes are semi-covered outside the polyimide film-fluorine 46 covered flat copper wires in a staggered way, a layer of low-resistance tape is semi-covered on the coil straight line part, a layer of high-resistance tape is semi-covered on the end part of the coil, a layer of dacron glass fiber interweaving tape is semi-covered on the outermost layer of the end part of the coil, and insulation material tapes are arranged between the coils. The insulation anticorona test is respectively carried out for the interturn insulation, interphase insulation and inter-coil insulation, homemade materials are adopted, the cost is low, the insulation thickness is reduced, the cross area of the care copper wire is effectively increased under the same condition, and the heat conducting capability of the insulation layer is improved.
Description
Technical field
The present invention relates to the electrical machine insulation field, relate in particular to a kind of rated operational voltage at the corona preventing construction of different, the synchronous INCREASEDSAFETY fire-proof motor of the three-phase alternating current of 10-11kV scope.
Background technology
INCREASEDSAFETY motor new standard GB3836.3-2010 has higher requirement to insulating between the turn-to-turn insulation of motor and alternate, line.The insulation system of current extensive employing does not satisfy this requirement, in insulation thickness, the heat radiation requirement, in the production process to the wrapping requirement of strength under, select domestic insulating material, by reasonable combination with for active component, meet the demands fully by test of many times and test proof, through the audit of national explosion-proof test center, now be used for production.
Summary of the invention
The object of the present invention is to provide a kind of corona-proof insulation structure that satisfies INCREASEDSAFETY motor new standard, all be better than now using structure aspect insulation thickness, heat conduction, insulating material mechanical strength and the technological operation simultaneously.
The present invention is achieved in that a kind of INCREASEDSAFETY motor for preventing coronal structure, comprise the coil straight line portion, unshakable in one's determination, end winding, it is characterized in that: coil turn-to-turn insulation adopts polyimide film-fluorine 46 wrapped flat type copper wires, described polyimide film-fluorine 46 wrapped flat type copper wire outside intersection half laps are surrounded by polyimide film single-side reinforced low resin mica tape and glass cloth single-side reinforced low resin mica tape, be surrounded by one deck low-resistance belt at coil straight line portion half lap, at the high stopband of end winding half-stack package one deck, described end winding outermost one deck half-stack package one deck dacron glass fiber band that interweaves; Be provided with insulating material belt between coil and the coil.
As optimization, described coil straight line portion intersection half lap is surrounded by 9-10 strata imide membrane single-side reinforced low resin mica tape and glass cloth single-side reinforced low resin mica tape; Described end winding intersection half lap is surrounded by 8-9 strata imide membrane single-side reinforced low resin mica tape and glass cloth single-side reinforced low resin mica tape.
The present invention carries out respectively isolated coronaproof test with insulation between turn-to-turn insulation, phase insulation, line, adopts the home made materials cost low, under attenuate insulation thickness, the same terms, effectively increased bare copper wire sectional area, improved the capacity of heat transmission of insulating barrier.In the mutual collocation combination of anticorona employing different materials, the control shared thickness of quantity of material and lapping structure and position have been satisfied the requirement of INCREASEDSAFETY motor new standard, and can have been promoted the insulation system of corona being had relatively high expectations for other.
