Description

Technical Field

[0001] The utility model belongs to the field of transformer bushing detection, in particular to a detection device for transformer bushing production. Background Art

[0002] At present, the bushing is mainly composed of a capacitor core, an oil pillow, a flange, and upper and lower porcelain sleeves. The main insulation is the capacitor core, which is composed of concentric capacitors connected in series and enclosed in a sealed container composed of upper and lower porcelain sleeves, an oil pillow, a flange and a base. The container is filled with treated transformer oil, making the internal main insulation an oil-paper structure. The contact surfaces between the main components of the bushing are lined with oil-resistant rubber gaskets. Each component is subjected to a central compression force applied by a set of strong springs set in the oil storage cabinet, so that the inside of the bushing is in a fully sealed state. The flange is equipped with a vent plug, an oil extraction device, and a device for measuring the dielectric loss (tan δ, referred to as dielectric loss) and partial discharge (PD) of the bushing. During operation, the outer cover of the measuring device must be covered to ensure that the end screen is grounded. It is strictly forbidden to open the circuit. The following items should be checked before installation of the transformer bushing: (1) Whether there are cracks or scratches on the surface of the porcelain sleeve, (2) Whether the neck of the bushing flange and the inner wall of the equalizing ball are clean, (3) Whether the bushing has passed the test, and (4) Whether the oil level indication of the oil-filled bushing is normal and whether there is oil leakage.

[0003] However, after the transformer bushing is produced, the porcelain sleeve is generally rotated by hand and the outer surface of the porcelain sleeve is visually observed. However, since the gap inside the porcelain sleeve is too small and the batch size of porcelain sleeves also causes inconvenience in subsequent inspection, a detection device for transformer bushing production is proposed.

[0004] Therefore, in view of the shortcomings of the above scheme in actual production and implementation, it has been revised and improved. At the same time, in the spirit and concept of seeking improvement, with the assistance of professional knowledge and experience, and after many ingenuity and experiments, the present utility model was created. In particular, a detection device for transformer bushing production is provided to solve the problem that after the production of the existing transformer bushing is completed, the porcelain sleeve is generally rotated by hand and the outer surface of the porcelain sleeve is visually observed. However, due to the small gap inside the porcelain sleeve and the batch of porcelain sleeves, subsequent inspection is inconvenient. Summary of the Invention

[0005] The utility model provides a detection device for transformer bushing production, which solves the problem in the prior art that after the production of transformer bushings is completed, the inspection items are as follows, such as whether there are cracks on the surface of the porcelain sleeve.
