Description
Technical field
The utility model relates to transformer technology field, is specifically a kind of dry type transformer with split winding high pressure lead wire structure.
Background technology
Along with China's rapid development of economy, country is increasing to the demand of the energy, and New Energy Industry fast development is got up.Solar energy is as a kind of clean type regenerative resource, and the energy resources that Ye Shi China is important are current technology maturations simultaneously, have the regenerative resource of large-scale development condition, is therefore more and more subject to all circles and payes attention to.Therefore, photovoltaic power generation transformer is then arisen at the historic moment, these series of products, in order to adapt to the feature of photovoltaic generation, limiting short-circuit current, reduce transformer number of units simultaneously, therefore the two splitted construction of winding need be designed to, two splitted construction can limiting short-circuit current effectively, is applicable to selecting light-duty switchgear, saves peripheral hardware investment, two transformers are united two into one simultaneously, reduce the device space and cost.China national intellectual property board web discloses a kind of two division dry-type distribution transformer high pressure lead wire structure, the leading point of A, B, C three-phase is placed on centre by it.This structure has the following disadvantages: due to the leading point of A, B, C three-phase is placed on centre, when therefore making this leading point be connected with high-voltage outlet terminal, stube cable and connecting rod is needed again to keep certain insulation distance, which not only adds the lead-in wire space of transformer, add cost, increase the volume of dry type transformer with split winding, and high-tension cable directly picks out from the terminal of resin-cast, cable weight adds the burden of high-voltage connection terminal, even damage high-voltage connection terminal by pressure, reduce the functional reliability of dry type transformer with split winding.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of high-voltage connection compact, and high-tension cable wiring is reliable, and can not increase the dry type transformer with split winding high pressure lead wire structure of dry type transformer with split winding volume.
The technical solution of the utility model is, a kind of dry type transformer with split winding high pressure lead wire structure is provided, comprises A phase terminal point, B phase terminal point, C phase terminal point, X phase terminal point, Y phase terminal point, Z phase terminal point, A ' phase terminal point, B ' phase terminal point, C ' phase terminal point, X ' phase terminal point, Y ' phase terminal point, Z ' phase terminal point and six tap terminals; Described A phase terminal point, B phase terminal point, C phase terminal point are located at dry type transformer with split winding top, and on steel folder, are fixed the binding post of high pressure A, B, C phase by special isolation after upwards being drawn by cable; Described A ' phase terminal point, B ' phase terminal point, C ' phase terminal point are located at dry type transformer with split winding bottom; Described X phase terminal point, Y phase terminal point, Z phase terminal point, X ' phase terminal point, Y ' phase terminal point and Z ' phase terminal point are located in the middle part of dry type transformer with split winding; Described A phase terminal point is connected by the first high pressure connecting rod with Z ' phase terminal point with Z phase terminal point, A ' phase terminal point; Described B phase terminal point is connected by the second high pressure connecting rod with Y ' phase terminal point with X ' phase terminal point, C ' phase terminal point with Y phase terminal point, B ' phase terminal point with X phase terminal point, C phase terminal point; Described X phase terminal point is connected by gear shunting piece with Z ' phase terminal point with Y ' phase terminal point, Z phase terminal point with X ' phase terminal point, Y phase terminal point; Insulation distance is provided with between the first described high pressure connecting rod and the second high pressure connecting rod.
Six described tap terminals are horizontally set.
After adopting above structure, the utility model compared with prior art, has the following advantages:
The utility model dry type transformer with split winding high pressure lead wire structure is due to by A, B, the leading point of C three-phase is placed on transformer top, directly to upper lead-in wire, high-tension cable binding post can be set on the reliable steel folder of intensity, when therefore making this leading point be connected with high-voltage outlet terminal, without the need to stube cable and connecting rod are kept certain insulation distance, this not only reduces the insulating space of lead-in wire, reduce cost, reduce the volume of dry type transformer with split winding, and the minimizing of high voltage cable alleviates the weight of high-tension cable, reliably can bear the weight of high-tension cable like this, thus avoid the burden causing high-voltage outlet terminal, more impossiblely damage high-voltage outlet terminal by pressure, thus make the functional reliability of dry type transformer with split winding higher, horizontal tap terminals design, add tap terminals and the direct distance of high-voltage connection dexterously, solve dry type transformer with split winding volume little, binding post is many, the problem that insulation distance is inadequate.
