The pole coils are of a tubular structure. Every two adjacent pole coils are fixedly connected through welding. Welded welding lines A are located on the two side edges of a gap formed by the side walls of every two adjacent pole coils, the two ends of the pole coils are provided with cover plates respectively, and pipe openings of the multiple pole coils are shielded through the cover plates. According to the structure and the end closing structure of the pole coils of the transformer, the cover plates are arranged in the pipe openings in the two ends of the pole coils respectively through welding, notches are full of welding fluid, the pipe openings of the pole coils are closed through welding lines B, cooling water in pipes of the pole coils cannot overflow from the pipe openings, the cooling effect of the pole coils is guaranteed, the short circuit is avoided, and the service life of the transformer is prolonged.
Description
Technical field
The utility model relates to field transformer, is specifically related to a kind of end closed structure of pole coil of transformer.
Background technology
Transformer is application Faraday's electromagnetic induction law and raise or reduce the device of voltage.Transformer comprises two groups or above coil conventionally.Main application is voltage, change impedance and the isolating circuit of lifting alternating current.
In the structure of electric welding machine, transformer is a very important assembly, the transformer of using as welding power supply; By welding manner, can be divided into arc welding transformer and welding resistance transformer two classes.Electric welder transformer in use voltage is generally 1～30 volt, and electric current is depending on weldment thickness, generally all more than hundreds of peaces.So the pole coil of transformer inside can bear very high temperature, because the material of pole coil is copper, the temperature height of pole coil after can exert an influence to transformer, thereby affect the result of use of electric welding machine.The patent that the name that the applicant applies for is on the same day called the pole coil cooling structure of transformer has solved the problems referred to above, but because the glassware for drinking water in bosh has certain hydraulic pressure, generally in 10MPa left and right, and the end of two adjacent pole coils is generally all undertaken airtight by built-up welding when welding, but this air-tight manner is complicated operation not only, technological requirement is high, and can exist and do not weld real hidden danger, this welding manner needs a large amount of welding rods or welding wire in addition, cost is higher, and efficiency is lower.
Summary of the invention
The purpose of this utility model is: overcome the deficiencies in the prior art, a kind of end closed structure of pole coil of transformer is provided, cover plate is located at respectively to the mouth of pipe at pole coil both ends by welding, welding fluid is filled in tankful mouth, weld seam B makes the mouth of pipe of pole coil airtight, and in the pipe of pole coil, cooling water can not overflow from the mouth of pipe, guarantees the cooling effect of pole coil, avoid occurring short circuit, extend the useful life of transformer.
Technical solution adopted in the utility model is:
The end closed structure of the pole coil of transformer, comprise many set pole coils side by side, described pole coil is tubular structure, adjacent two pole coils are fixedly connected by welding, the dual-side edge in weld seam A formed gap between the sidewall of adjacent pole coil of welding, the both ends of described pole coil are provided with respectively cover plate, and described cover plate covers the mouth of pipe of many pole coils.
The further improvement project of the utility model is, described cover plate is fixing respectively with the both ends of pole coil by welding, and the weld seam B of welding is positioned at the lower edge of cover sidewall.
The utility model further improvement project is that described cover plate is airtight by the mouth of pipe of pole coil by weld seam B.
The utility model further improvement project is that the length of described cover plate is less than or equal to the ultimate range between outside and inner side pole coil, is more than or equal to the ultimate range between outside and the inner side pole coil mouth of pipe.
The utility model further improvement project is that the width of described cover plate is less than or equal to the width of pole coil, and is more than or equal to the width of the pole coil mouth of pipe.
The beneficial effects of the utility model are:
The end closed structure of the pole coil of transformer of the present utility model, cover plate is located at respectively to the mouth of pipe at pole coil both ends by welding, welding fluid is filled in tankful mouth, weld seam B makes the mouth of pipe of pole coil airtight, in the pipe of pole coil, cooling water can not overflow from the mouth of pipe, guarantee the cooling effect of pole coil, avoid occurring short circuit, extend the useful life of transformer.
