Description
Technical field
The invention belongs to the technical fields more particularly to a kind of high-voltage motor high osmosis impregnating varnish of insulating materials manufacture
And preparation method.
Background technique
Currently, high-voltage motor insulated structure is mainly still using the system of non-epoxy anhydride on domestic market.Using comparing
Successfully have two big series of products: one is epoxy-ester-phenylethylenes；Another kind is polyester-imide-phenylethylene.Epoxy
Ester-phenylethylene product has many advantages, such as low viscosity, good penetrability, stable storing, excellent electric properties, but there are volatile matters
The disadvantages of height, solidification temperature are high, the time is long, energy consumption is high, low efficiency；Polyester-imide-phenylethylene product have it is heat-resist,
The advantages that curing time is relatively short, stable storing, good mechanical property, but that there is also electric property nargin is few, water resistance is slightly worse
The disadvantages of.
And external large and medium-sized vacuum pressure impregnation of high voltage motor resin is substantially representative: one by two kinds of main products
It is using US Westinghouse company and French Alstom as the polystyrene systems of the epoxy polyester acid anhydrides of representative；The second is with moral
Siemens Company of state and Mitsubishi Corporation of Japan are the non-polystyrene systems of the epoxy anhydride of representative.The styrene of epoxy polyester acid anhydrides
The feature of environmental protection of system is not good enough；The non-polystyrene systems of epoxy anhydride can achieve the thinned purpose of insulation system, i.e. insulation thickness
Be thinned and electric property will improve instead, but this kind of resin storage and in use, easily be easily polluted by the external foreign matters and viscosity increase, insulation
Reduced performance, very sensitive to environment temperature, the heating repeatedly of impregnating resin is cooling to be used, and is wasted a large amount of energy, is reduced
Production efficiency, therefore in practical applications, receive larger limitation.
Currently, the related patents of high-voltage motor insulated structure are as follows both at home and abroad:
Chinese patent CN201210483323.1 describes a kind of high-voltage motor impregnated insulating paint and preparation method thereof, adopts
With unsaturated polyester modified epoxy resin, epoxy resin, unsaturated diluent, latent curing agent, peroxide are added
Initiator, epoxide diluent and levelling agent composition；Chinese patent CN201310046980.4 describes a kind of high-voltage motor without molten
Agent impregnating resin and curing method, using heat resisting unsaturated polyester, Ben Bing E piperazine imide resin, epoxy resin, reactive diluent,
The impregnating varnish that curing agent, promotor, initiator form, feature is that high-low pressure is general, and H-C grades general；Chinese patent
CN201020243735.4 describes a kind of high-voltage motor insulated structure of ten KV levels, lacks glue using double glass cloth reinforced mediate amount epoxy
Four layers of mica paper tape half-stack package formed in main insulating layer, then with double glass cloth reinforced mediate amount epoxy dry mica paper tape half-stack package four
Layer forms outer main insulating layer, and polyester-epoxy-anhydride-styrene type impregnating resin of arranging in pairs or groups forms final high-voltage motor insulated knot
Structure.But impregnating varnish involved in above-mentioned patent, the feature of environmental protection is insufficient, and cannot achieve the purpose that insulation is thinned.
Chinese patent CN201210566052.6 describes high voltage motor stator major insulation ultra-thin insulated technique, using ring
Three layers of oxygen polyester film dry mica half-stack package form insulation system, the epoxy anhydride with epoxy anhydride solvent-free immersion paint
Although system has achieved the purpose that insulation is thinned, is energy-saving, but the stable storing sexual deviation of epoxy anhydride system, causes to insulate
Service life is difficult to be expected.
Chinese patent CN201410771173.3 describes high-voltage motor stator coil insulation system and its dipping and solidification
Technique, using organosilicon solvent-free dip varnish with four layers of half-stack package of Kapton glass cloth dry mica paper tape form it is exhausted
Edge structure, for temperature resistant grade up to 220 grades, the organosilicon systems high temperature resistant grade is high and insulation life is long but at high cost, and bakes temperature
Degree is high, and application range receives limitation.
It can be seen that research and develop it is a kind of not only can with reduction insulation structure, improve electric property, but also can overcome that viscosity is big, temperature
The high environment-friendly type high osmosis high-voltage motor insulating impregnating varnish of susceptibility, has a very important significance the art.
