Abstract
The utility model discloses a body insulation structure of a distribution transformer. The body insulation structure comprises a high-tension coil, a low-tension coil, an insulating cylinder, an angle ring, spaced partitions, an iron yoke spacer, iron yoke insulating members and an iron yoke partition. The insulating cylinder is disposed outside the low-tension coil and the high-tension coil. The angle ring is disposed between the low-tension coil and the high-tension coil. The spaced partitions are disposed on one side of the angle ring. The iron yoke partition is disposed at the upper ends of the high-tension and low-tension coils. The iron yoke spacer is disposed at the lower ends of the high-tension and low-tension coils. After the angle ring is added between the low-tension coil and the high-tension coil, influence of mutual induced voltage between the high-tension and low-tension coils is fully blocked, internal electric field is more uniform, and electric field concentration is avoided. After the insulating cylinder is added outside the high-tension and low-tension coils, support for inner peripheries of the high-tension and low tension coils is enhanced, and resistance to high-tension short circuit impact is enhanced. The body insulation structure is simple in structure and reasonable in layout and better guarantees insulation and tightness of a transformer body.
Description
Technical field
The utility model relates to a kind of insulating structure of distribution transformer body.
Background technology
Distribution transformer in the electrical power distribution system is more and more at present, transformer is to utilize the principle of electromagnetic induction to change the device of alternating voltage, in electric equipment and radio-circuit, be commonly used for lifting voltage, matched impedance and safety isolation etc., loss is low, the transformer of environment-friendly type is more and more favored, if adopt traditional insulation system form, insulation processing between the high-low pressure is bad, to directly affect the running quality of transformer, affect the useful life of transformer, bring loss to the user.
Summary of the invention
Technical problem to be solved in the utility model provides preferably insulating structure of distribution transformer body of a kind of insulating properties and sealing.
The utility model is achieved through the following technical solutions: a kind of insulating structure of distribution transformer body, comprise high-tension coil, low-voltage coil, insulating cylinder, square ring, phase partition, iron yoke cushion block, core insulation and iron yoke dividing plate, described insulating cylinder is arranged on low-voltage coil and the high-tension coil outside, described square ring is arranged between low-voltage coil and the high-tension coil, described phase partition is arranged on square ring one side, described iron yoke dividing plate is arranged on high-tension coil and low-voltage coil upper end, described iron yoke cushion block is arranged on high-tension coil and low-voltage coil lower end, and described core insulation is arranged on iron yoke cushion block upper end.
As preferably, described phase partition has two.
As preferably, the number of described insulating cylinder is six.
The beneficial effects of the utility model are: increase between low-voltage coil and high-tension coil after the square ring, just intercept the impact of the voltage that interacts between the high and low pressure coil fully, so that internal electric field is more even, the phenomenon of having avoided electric field to concentrate, it is after increasing insulating cylinder between the high and low pressure coil, so that the support of high and low pressure internal coil diameter has obtained reinforcement, increased high pressure Short Circuit withstand impact capacity, simple in structure, rationally distributed, can better guarantee integral insulation and the sealing of device body.
