The utility model discloses a to not have excitation pressure regulating dry -type transformer high -pressure coil and be tip pressure regulating structure by middle part pressure regulating structural change, and make no excitation pressure regulating dry -type transformer high -pressure coil structure and on -load voltage regulation dry -type transformer high -pressure coil in full accord, and its shunting lead wire preparation is simpler, and is insulating more reliable between the lead wire, does not have the cross -line, can regard as no excitation pressure regulating dry -type electrical transformer to use at the project construction initial stage, on -load voltage regulating switch can be disposed to the later stage, and the practicality is stronger.
Description
Technical field
The utility model relates to dry-type transformer manufacturing technology field, and especially a kind of large-scale dry-type power transformer is transferred the files structure.
Background technology
In recent years, resin casting dry-type transformer obtains fast development in China and the whole world, and this volume of transformer is little, lightweight, and occupation of land space is little, can be non-maintaining.The important place of large-scale dry-type power transformer one, in big and medium-sized cities, two wires and national economy is all used widely, and large-scale dry-type power transformer separate unit is worth large, and mating switch price is also very high.But large-scale dry-type power transformer generally can only customize, cannot by non-excitation pressure adjustment and the unification mutually of load tap-changing dry-type power transformer body, therefore versatility has much room for improvement.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of large-scale dry-type power transformer to transfer the files structure, can realize non-excitation pressure adjustment and on-load voltage regulation body is general on a Cast Resin Dry-Type Transformer.
The utility model solves the technical scheme that its technical problem adopts: a kind of large-scale dry-type power transformer is transferred the files structure, the high-tension coil comprising housing, be arranged on the multiple outlet port in housing outer surface and be arranged in housing; Described high-tension coil has multiple wiring tap; Described wiring tap is all drawn by the outlet port being arranged on surface of shell; The corresponding wiring tap of a described outlet port; Realize transferring the files by conducting strip and conduction connecting screw rod between described outlet port.
Further, conducting strip described in the utility model is copper bar; Described copper bar surface is provided with the screw equal with outlet port number; One end of described copper bar is fixedly connected with one of them outlet port by conduction connecting screw rod; The other end of copper bar is flexibly connected with remaining outlet port by another conduction connecting screw rod.
Further say, housing outer surface described in the utility model is also provided with input terminal and output terminal; Removably connect between described input terminal and output terminal on-load voltage regulation switch.
Further say, outlet port interleaving arrangement described in the utility model.
The beneficial effects of the utility model are, solve the defect existed in background technology, by being end pressure adjusting structure by non-excitation pressure adjustment dry transformer high-tension coil by middle part voltage regulating structural change, make non-excitation pressure adjustment structure of high-voltage coil for dry-type transformer and load tap-changing dry-type transformer high-tension coil completely the same; And its tap lead makes simpler, insulate between lead-in wire more reliable, there is no cross-line; Can use as non-excitation pressure adjustment dry-type power transformer at the project construction initial stage, later stage configurable on-load voltage regulating switch, practicality is stronger.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the end view after Fig. 1 increases conducting strip and conduction connecting screw rod;
Fig. 3 is the utility model high-voltage coil structure schematic diagram;
In figure: I, housing; II, outlet port; III, conducting strip; IV, conduction connecting screw rod.
Embodiment
With preferred embodiment, the utility model is described in further detail by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
The large-scale dry-type power transformer of one is as shown in Figure 1-2 transferred the files structure, the high-tension coil comprising housing I, be arranged on the multiple outlet port II in housing outer surface and be arranged in housing; Outlet port interleaving arranges.Housing outer surface is also provided with input terminal and output terminal; Removably connect between described input terminal and output terminal on-load voltage regulation switch.
High-tension coil has multiple wiring tap; Described wiring tap is all drawn by the outlet port being arranged on surface of shell; The corresponding wiring tap of a described outlet port; Realize transferring the files by conducting strip III and conduction connecting screw rod IV between described outlet port.Conducting strip is copper bar; Described copper bar surface is provided with the screw equal with outlet port number; One end of described copper bar is fixedly connected with one of them outlet port by conduction connecting screw rod; The other end of copper bar is flexibly connected with remaining outlet port by another conduction connecting screw rod.
As shown in Figure 3, high-tension coil has a shunting tap section, wherein sequence number is that 1,2,3,4,5,6,7,8,9 taps are taken out in same section, sequence number be 0 tap by internal layer second segment extract out (artificial mid point), all taps are all guided on outlet port; The gear of the high-tension coil shown in Fig. 3 is 9 grades; Regulation stall is adjusted to 9 grades by 0-1,0-2,0-3,0-4,0-5,0-6,0-7,0-8,0-9, order by 1 grade.When transformer non-exciting regulation uses, realize pressure regulation by copper bar.
An epoxy resin pouring dry type power transformer realizes non-excitation pressure adjustment and on-load voltage regulation body is general, non-excitation pressure adjustment dry-type transformer only need increase an on-load voltage regulating switch, just can be used as load tap-changing dry-type transformer and uses.
The just embodiment of the present utility model described in above specification, various illustrating is not construed as limiting flesh and blood of the present utility model, person of an ordinary skill in the technical field after having read specification can to before described embodiment make an amendment or be out of shape, and do not deviate from essence and the scope of utility model.
