Description

The capacitor arrangement of the double fabrication holes of band

Technical field

The utility model is related to a kind of capacitor arrangement, and the capacitor arrangement of the double fabrication holes of especially a kind of band belongs to electricity Power equipment technical field.

Background technology

For the internal capacitor using maceration extract, it usually needs a fabrication hole is set on housing, for vacuumizing And oiling.Capacitor common at present is vacuumized and carried out with oiling on this fabrication hole all only with a hole.As schemed It is the structure that single fabrication hole is set on capacitor top cover plate common at present, either simplex skill shown in 1-1, Fig. 1-2 and Fig. 1-3 Hole position is between 2 sleeve pipes.It is that single fabrication hole is set on capacitor casing leptoprosopy as shown in Fig. 2-1, Fig. 2-2 and Fig. 2-3 Structure.

The content of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art there is provided a kind of capacitor of the double fabrication holes of band Structure, can shorten the manufacturing cycle using double fabrication holes, enhance product performance.

The technical scheme provided according to the utility model, the capacitor arrangement of the double fabrication holes of the band, including capacitor protector Body, sets two sleeve pipes in the top blind flange of capacitor casing, it is characterized in that：Two works are set in the capacitor casing Skill hole.

In a detailed embodiment, described two fabrication holes are arranged between two sleeve pipes.

In a detailed embodiment, described two fabrication holes are arranged on the leptoprosopy of the sidepiece of capacitor casing.

The capacitor arrangement of the double fabrication holes of band described in the utility model can shorten the manufacturing cycle, enhance product performance.

Embodiment

With reference to specific accompanying drawing, the utility model is described in further detail.

Embodiment one：

As shown in Fig. 3-1, Fig. 3-2 and Fig. 3-3, the capacitor arrangement of the double fabrication holes of band described in the utility model includes electric capacity Device housing 1, sets two sleeve pipes 2 in the top blind flange of capacitor casing 1, and two fabrication holes are set between two sleeve pipes 2 3。

Embodiment two：

As shown in Fig. 4-1, Fig. 4-2 and Fig. 4-3, the capacitor arrangement of the double fabrication holes of band described in the utility model includes electric capacity Device housing 1, two sleeve pipes 2 are set in the top blind flange 1 of capacitor casing 1, are set on the leptoprosopy of the sidepiece of capacitor casing 1 Put two fabrication holes 3.

The capacitor arrangement of the double fabrication holes of band described in the utility model was manufactured using the structure of double fabrication holes in capacitor Cheng Zhongyu is vacuumized, oil filling pipeline is attached, and capacitor is vacuumized and during oiling technique, using duplexing skill pore structure Through-current capacity, which increases, to be twice, and substantially reduces finding time for moisture and gas in tank of power capacitor；Simultaneously can in vacuum impregnation To realize that a hole carries out vacuumize process, another hole carries out oiling simultaneously, so that it is guaranteed that retaining during oiling in case shell minimum Air cavity, the bubble that oil injection center inner impact is produced also extracted out outside case shell in time, it is ensured that capacitor interior insulation oil note foot note It is full.

The discontented phenomenon of oil, can improve the part of capacitor product when the utility model can solve the problem that capacitor single hole oiling Discharge level, improves the service life of product.
