Embodiment Construction
[0021] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.
[0022] like figure 1 , 2 As shown, a distribution transformer low-voltage coil structure, which includes A-phase coil 1, B-phase coil 2 and C-phase coil 3 wound on their respective core columns; wherein,
[0023] The A-phase coil 1 is sequentially wound with four layers of coils from the corresponding core posts, which are the first-layer coil of A-phase, the second-layer coil of A-phase, the third-layer coil of A-phase and the fourth-layer coil of A-phase. Lead out the first tap head 11 of phase A from the first layer coil of phase A, lead out the second tap head 12 of phase A from the second layer coil of phase A, and lead out the third tap head of phase A from the third layer coil of phase A Connect the outlet 13, and lead out the fourth tap o...

The invention discloses a low-voltage coil structure of a distribution transformer, which comprises A-phase coil, B-phase coil and C-phase coil wound on respective core posts; wherein the A-phase coilis wound with four layers of coils from the corresponding core pillar outward in turn, which respectively are an A-phase first layer coil , an A-phase second layer coil, an A-phase third layer coil and an A-phase fourth layer coil, wherein the phase A first tap is led out from the phase A first layer coil, the phase A second tap is led out from the phase A second layer coil, the phase A third tapis led out from the phase A third layer coil, and the phase A fourth tap is led out from the phase A fourth layer coil; the B-phase coil is wound with four layers of coils from the corresponding corepillar outward, namely, the B-phase first layer coil, the B-phase second layer coil, the B-phase third layer coil and the B-phase fourth layer coil. The invention can improve the phenomenon of three-phase load unbalance in the distribution transformer, has the function of three-phase filtering and balancing, reduces the electric energy loss caused by the three-phase load unbalance of the distribution transformer, and saves electric energy by more than 10%.
Description
technical field [0001] The invention relates to a low-voltage coil structure of a power distribution transformer. Background technique [0002] At present, in the existing low-voltage coil structure of distribution transformers, the A, B, and C three-phase coils are relatively independent of each other, and each bears a single-phase load; this traditional structure has little effect on unbalanced three-phase loads that are common in operation. play any role. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a distribution transformer low-voltage coil structure, which can not only improve the unbalanced three-phase load in the distribution transformer, but also have the function of three-phase filter balance, Reduce the power loss of distribution transformers caused by unbalanced three-phase loads, saving more than 10% of power. [0004] The technical solution adopted by t...
