Description
Technical field
The utility model relates to a kind of transformer, especially a kind of dry transformer for ozone generator.
Background technology
At present, structurally can be divided into two types at the dry-type transformer that uses: solid insulation is sealed winding and is not sealed winding.
Solid insulation is sealed the transformer integral body of winding by epoxy resin bag quilt, the heat that Transformer Winding produces will just can be delivered in the air through heavy obstruct, has caused the temperature of winding will be higher than the sealing material in the outside far away, and it is bad to dispel the heat, the copper that transformer uses increases cost up.
Do not seal the transformer of winding because winding exposes in air, and heat radiation is good, but has caused another kind of bad influence, be easy to be subjected to the filthy and steam invasion and attack of dust, insulation descends, the transformer job insecurity.
Summary of the invention
The utility model is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, heat dissipation ventilation good, super nameplate serviceability is strong, the degree that reliability height, coil be subjected to filth, make moist is low, loss and the low dry transformer for ozone generator of noise.
The purpose of this utility model is to adopt following technical proposals to realize: a kind of dry transformer for ozone generator, comprise housing, high-tension coil, low-voltage coil, the high and low pressure coil is located in the housing, between the high and low pressure coil cover around, be provided with insulating cylinder between the high and low pressure coil, insulating cylinder is provided with the axial ventilation louvre, like this can be on the basis of original rated capacity decreased average 20% loss and/or significantly improve the capacity of existing equipment, average size can increase by 50%, some equipment even can increase by 100%.Loss was lower when load descended, and the load summit phase can provide bigger capacity again.And reliability strengthens and the fringe benefits such as minimizing of maintenance workload also make these choices of technology more attractive economically.Hull outside is provided with screen.
Described low-voltage coil is the several paralleled conductor laminar, and wherein turn insulation and layer insulation adopt the epoxy resin embedding.
Described high-tension coil is the cake formula, adopts the pectination stay between the line cake.
Described insulating cylinder is made by epoxy resin.
Described screen is a Copper Foil.
Low-voltage coil of the present utility model is the several paralleled conductor laminar, and turn insulation and layer insulation all adopt the epoxy resin embedding.High-tension coil is the cake formula, adopts the pectination stay between the line cake, makes that like this ceiling voltage between cake has reduced half, has also improved the axial anti-short circuit capability of high-tension coil greatly.High-voltage coil and low-voltage coil overlap around, strengthened mechanical strength, reduced leakage inductance.Insulating cylinder between the high-low pressure is made with epoxy resin, and ventilating heat dissipating hole is reserved with mould in the centre.Its impregnation technology adopts VPI vacuum, pressure impregnation, and high temperature drying is solidified.In order to reduce high frequency radiation, add one deck Copper Foil as screen in the transformer outside, can effectively reduce electromagnetic radiation influence to external world.
Characteristics of the present utility model are that the contact area of high and low pressure coil and air is big, benefit is that heat dissipation ventilation is good, and super nameplate serviceability is strong, sometimes also because the restriction of load loss, coil temperature rise has bigger nargin, thereby the reliability of transformer is increased.Also reduced simultaneously the degree that coil is subjected to filth, makes moist.
Description of drawings
Fig. 1 is the utility model plan structure schematic diagram;
Fig. 2 is a side-looking structural representation of the present utility model;
Wherein 1. housings, 2. high-tension coil, 3. low-voltage coil, 4. insulating cylinder, 5. ventilating heat dissipating hole, 6. screen.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Among Fig. 1, Fig. 2, high and low pressure coil 2,3 is located in the housing 1, between the high and low pressure coil 2,3 cover around, be provided with insulating cylinder 4 between the high and low pressure coil 2,3, insulating cylinder 4 is provided with axial ventilation hole 5, low-voltage coil 3 is the several paralleled conductor laminar, and turn insulation and layer insulation all adopt the epoxy resin embedding.High-tension coil 2 is the cake formula, adopts the pectination stay between the line cake, makes that like this ceiling voltage between cake has reduced half, has also improved the axial anti-short circuit capability of high-tension coil 2 greatly.High and low pressure coil 2,3 overlap around, strengthened mechanical strength, reduced leakage inductance.Insulating cylinder 4 usefulness epoxy resin between the high and low pressure coil 2,3 are made, and are middle with mould reservation ventilating heat dissipating hole 5.Its impregnation technology adopts VPI vacuum, pressure impregnation, and high temperature drying is solidified.In order to reduce high frequency radiation, add one deck Copper Foil as screen 6 in transformer housing 1 outside, can effectively reduce electromagnetic radiation influence to external world.
The utility model adopts the technologies such as flowability, mould and curing of vacuum degree, epoxy resin to guarantee, gets rid of bubble coil is tightly sealed.Roughly can divide four-stage:
1, coil winding, arrangement are cured drying after finishing, and this is a very important stage, because all dry-type transformer coils can not carry out the drying second time again.Usually adopt the drying room constant pressure and dry, the strict process operation sequence should be arranged according to different specifications.Can adopt high temperature (180-190 ℃), time weak point or middle temperature (140 ℃), long slightly drying means of time.
2, make transformer suitably after the cooling, it is inserted in the impregnation tank, inject epoxy resin under the state of vacuum, and keep a period of time, epoxy resin will be penetrated in the slit of coil this moment.
3, remove vacuum, change pressure into, under the high pressure of 0.5Mpa, epoxy resin will be pressed in each slight gap.Such dipping effect is more much better than only using vacuum-impregnated method.
4, the coil after above processing, high temperature drying is solidified.
