Abstract
The utility model discloses a 6-10 kV double-voltage dry type transformer coil structure with the same linking group. The 6-10 kV double-voltage dry type transformer coil structure with the same linking group comprises high-voltage coils in each phase, and each high-voltage coil is provided with 16 outgoing line terminals. The 6-10 kV double-voltage dry type transformer coil structure with the same linking group has the advantages that compared with an existing 6-10 kV double-voltage dry type transformer with 'D' connection and 'Y' connection conversion, due to the fact that the internal structure of the high-voltage coils is changed and the outgoing line terminals are wired according practical working requirements of a transformer, obtained output voltage of the 6-10 kV double-voltage dry type transformer coil structure with the same linking group is more accurate, the situation that parallel groups are not the same is overcome, and using requirements under different voltages are met.
Description
Technical field
The utility model relates to a kind of double-voltage dry type transformer, particularly a kind of identical 6-10kV double-voltage dry type transformer loop construction of group that connects.
Background technology
In the access distribution transformer occasion of specific (special) requirements was arranged, namely the transformer high-voltage winding had 6kV access situation, might access situation by 10kV again, was generally and satisfied this two kinds of situations, utilized 6kV and 10kV voltage ratio to approach
The basis, in 6kV access situation, transformer connects for " D " and connects, in 10kV access situation, transformer connects for " Y " and connects.
In fact access the distribution transformer occasion, have the problem of transformers connected in parallel, connect group and require unanimously, and " D " connect with " Y " and connect conversion, can not to connect group consistent with on-the-spot other transformer, inconsistently then can not access.
Usually supply network 6kV level has: 6kV, 6.3kV, three kinds of voltages of 6.6kV, and the 10kV level has: 10kV, 10.5kV, three kinds of voltages of 11kV, utilize voltage ratio to approach fully
, then be difficult to satisfy.
The two voltage transformers of 6-10kV refer to two voltage transformers that any voltage makes up mutually in these two kinds of electric pressures, and the combination of 3 * 3=9 kind is arranged in theory.
The utility model content
Utility model purpose: for the problems referred to above, the purpose of this utility model provide a kind of high-voltage coil and low-voltage coil number of windings identical with the common double winding transformer, connect the double-voltage dry type transformer loop construction that group is identical, input voltage is 6kV or 10kV, make to connect that group is consistent, output voltage is more accurate.
Technical scheme: a kind of identical 6-10kV double-voltage dry type transformer loop construction of group that connects, comprise the high-tension coil of every phase, described high-tension coil is provided with 16 outlet terminals.
Described 16 outlet terminals are distributed into 3 tap region by 4,8,4 successively from input to output, and described 3 tap region are separated into 4 wire turn sections with described high-tension coil.
Principle of the present utility model is that high-voltage coil structure is carried out modularized design, when transformer uses, according to actual electric network voltage, winding wiring requirement by design of transformer, the method that adopts local string and connect connects corresponding outlet terminal, obtains the number of turn with the input voltage corresponding requirements.The high pressure winding of transformer is no matter access from the access of 6KV step voltage or from the 10KV step voltage, but the number of windings is the same with the common double winding transformer, identical high-tension coil of every phase, an identical low-voltage coil, be that the high-voltage coil and low-voltage coil number of windings is identical, low pressure output is identical, short-circuit impedance is close, connects group and does not change.
Beneficial effect: compared with prior art, the utility model has the advantages that by changing the high-tension coil internal structure, require the wiring outlet terminal according to the transformer real work, connect with " D " of existing 6-10kV double-voltage dry type transformer and to connect conversion with " Y " and compare, the output voltage that obtains is more accurate, overcome the inconsistent situation of group in parallel, satisfied the instructions for use of different voltages.
