Abstract
A kind of transformer housing structure, comprising: upper shell and lower casing are engaged between the upper shell and the lower casing by clip assembly；The clip assembly includes: upper lug, one end of two upper lug and the upper cage connection, and the other end of two upper lug extends towards the lower casing, forms groove between two upper lug；One end of lower lug, two lower lug is connect with the lower casing, and the other end of two lower lug extends towards the upper shell, and two lower lug form tongue；The tongue and the matching grooves.Scheme compared with the existing technology, the present invention changes shape at the enclosure interface of transformer housing structure and improves dielectric level, makes the rated insulation level in (0.66/3kV, height above sea level≤1000 meter, national standard) on the basis of be increased to 0.66/6kV, 3000-5000 meters of height above sea level.
Description
Technical field
The present invention relates to electricity field more particularly to mutual inductor, especially a kind of transformer housing structure.
Background technique
In the prior art, the interface mode of transformer casing can only meet rated insulation level (0.66/3kV, height above sea level≤
1000 meters, national standard), it is not able to satisfy the safety used in high altitude localities.
Summary of the invention
For the technological deficiency of the prior art, the purpose of the present invention is to provide a kind of mutual inductances for solving above-mentioned technical problem
Device shell structure.
In order to solve the above technical problems, transformer housing structure provided by the invention, comprising: upper shell and lower casing, institute
It states and is engaged between shell and the lower casing by clip assembly；The clip assembly includes: upper lug, and two described prominent
One end of part and the upper cage connection, the other end of two upper lug extends towards the lower casing, described in two
Groove is formed between upper lug；One end of lower lug, two lower lug is connect with the lower casing, two lower lug
The other end extend towards the upper shell, two lower lug form tongues；The tongue and the matching grooves.
Two lower lug are located at the inside of two upper lug.
The outer wall of two lower lug is bonded with the inner wall of two upper lug of two sides respectively.
The upper lug and the lower lug are centrum shape structure, and the smallest width of centrum shape structure top end is
1.0 millimeter.
The length of the upper lug and the lower lug is 8.01 millimeters.
The groove is trapezoidal.
Scheme compared with the existing technology, the present invention change shape at the enclosure interface of transformer housing structure and insulate to improve
Level makes rated insulation level be increased to 0.66/6kV on the basis of (0.66/3kV, height above sea level≤1000 meter, national standard),
3000-5000 meters of height above sea level.

Specific embodiment
Transformer housing structure of the present invention is described in further detail with reference to the accompanying drawing.
As shown in fig. 1~fig. 5, transformer housing structure provided by the invention, comprising: upper shell 100 and lower casing 300,
Engaged between upper shell 100 and lower casing 300 by clip assembly；Clip assembly includes: upper lug 110, two upper lug 110
One end connect with upper shell 100, the other ends of two upper lug 110 extend towards lower casing 300, in two upper lug 110
Between formed groove 500；One end of lower lug 310, two lower lug 310 is connect with lower casing 300, two lower lug 310
The other end extends towards upper shell 100, and two lower lug 310 form tongue 600；Tongue 600 is matched with groove 500.
Two lower lug 310 are located at the inside of two upper lug 110.The outer wall of two lower lug 310 is respectively with two
The inner wall fitting of the upper lug 110 of two of side.The upper lug 110 and lower lug 310 are centrum shape structure, the centrum shape
The smallest width of structure top end is 1.0 millimeters.The length of upper lug 110 and lower lug 310 is 8.01 millimeters.Groove is trapezoidal.
Such setting is so that the winding conductor 400 and shell of iron core 200 extend along the distance between insulating surface, in addition
Clip assembly, the two, which combines, improves dielectric level, and rated insulation level is made to be increased to 0.66/6kV, and 3000-5000 meters of height above sea level.
The preferred embodiment of the present invention has been described in detail above, but the invention is not limited to implement
Example, those skilled in the art can also make various equivalent modifications on the premise of not violating the inventive spirit of the present invention
Or replacement, these equivalent variation or replacement are all included in the scope defined by the claims of the present application.
