Description
One, technical field:
The invention belongs to a kind of dry-type transformer, relate in particular to a kind of multi-stage dry voltage regulating transformer.Be applicable to that particularly polysilicon smelts usefulness, can realize the multi-stage dry voltage regulating transformer of many gears transformation, also can be used for the operating environment of other many gears of needs transformation.
Two, background technology:
Along with current society is more and more higher to the requirement of environmental protection and energy use, solar energy receives much concern as a kind of renewable free of contamination energy.Need in the use of solar energy with a large amount of polysilicons, reacting furnace is a necessaries of producing polysilicon.According to the special process process of production of polysilicon, the transformer that present domestic reacting furnace adopts is the oil-filled transformer of import all, and it costs an arm and a leg, safeguard frequently, and the maintenance cost height, and influence is produced.In addition, the user is in order to improve the output of polysilicon, must boost and increase mixed gas flow reacting furnace, increase mixed gas flow and then need to increase lot of energy, and the oil-filled transformer capacity of import is low, can not satisfy the needs that increase mixed gas flow, thereby has influenced quality, the output of production of polysilicon, even can cause that tripping operation has a power failure, and has a strong impact on ordinary production.In addition,, mostly be oil-filled transformer, and range of regulation generally is no more than 10%, can not satisfies the needs of reacting furnace (reacting furnace) production polysilicon though at present many grades transformer is arranged.
Three, summary of the invention
The purpose of this invention is to provide a kind of multi-stage dry transformer, its high pressure winding coupling group adopts three-phase, and low pressure is used single-phase; The low pressure winding can be exported various different voltages and electric current simultaneously, and range of regulation is big.
For achieving the above object, the technical scheme that the present invention takes is: adopt a plurality of low-voltage coils to form the method for low pressure winding.Promptly include iron core, folder from top to bottom, high-low pressure winding etc., the high-low pressure winding is sleeved on the iron core, and folder from top to bottom is arranged on the two ends up and down of iron core, is provided with insulating cylinder between the high and low pressure winding.The low-voltage coil of winding mesolow winding is no less than 2, and low-voltage coil is provided with the insulating radiation air flue according to voltage height suit successively from outside to inside between two adjacent low-voltage coils.Each low-voltage coil is provided with tap, and the other end of tap is connected with the insulated terminal of the low pressure of transformer output.So just, can obtain the low pressure of shelves identical number and current gear number of times (as 2 grades, 3 grades, 4 grades, 6 grades, even 8 grades etc.) with the low-voltage line number of turns; And each low-voltage coil can design as required, and the pressure regulation rate just can break through 10% scope.
Winding mesohigh coil is wire-wound, resin-cast, segmented layered structure; Low-voltage coil is that paper tinsel is around structure.
For the ease of heat radiation, the high-tension coil inside in the winding is provided with air flue I, is provided with the air flue II that insulating stay supports between each low-voltage coil.The heat that produces during transformer work dispels the heat by air flue I, II.
High pressure adopts three-phase to connect with high-voltage fence in use, and low pressure adopts single-phase connection.When high pressure access electrical network, the low pressure winding produces the low voltage voltage shelves number identical with the low-voltage line number of turns.Just can carry out fluid drive by AEG or other control system of using equipment, to satisfy the instructions for use of equipment.
Because the present invention adopts a plurality of low-voltage coil suits to form the method for the low pressure winding in the winding, the quantity of low-voltage coil can come to determine as required, each low-voltage coil can design as required, also can correspondingly improve simultaneously the capacity of transformer, satisfy the needs of many grades of voltages of equipment use.Therefore, the present invention has when low pressure can export various different voltages and electric current simultaneously, and characteristics such as range of regulation is big.Can the satisfy the demand equipment instructions for use of many grades of pressure regulation.
