Refer to shown in Fig. 1, during existing high-voltage power capacitor runs, noise is huge, bring larger being stranded to productive life
Disturb；Noise mainly spreads out of above and below capacitor unit, and during high-voltage power capacitor runs, noise reduction is referred to as a difficult problem.
Capacitor casing 1 has been referred to as a kind of reliable noise reduction mode using cavity cap and cavity bottom.
However, make cavity bottom in the bottom 11 of capacitor casing 1 submit simply, but cavity cap is due to involving two
Outgoing line porcelain bushing 26, prior art is difficult to.
Utility model content
The purpose of this utility model is to provide a kind of high-voltage power capacitor unit and its noise reduction cavity integral cap to go out
Thread casing, to solve above-mentioned technical problem.
To achieve these goals, this utility model adopts the following technical scheme that：
A kind of noise reduction cavity integral cap outlet casing tube, including two vertical and spaced insulator, upper capacitor covers
Plate and noise reduction cover plate；Upper capacitor cover plate passes through the bottom that rolling is fixed on two insulators；On two insulators, each rolling is connected with
One flange, flange and upper capacitor cover plate interval setting, centre is separated with a section of insulator；Two through holes are had on noise reduction cover plate,
This two through holes are enclosed within companion flange periphery, and and flange welding；Upper capacitor cover plate is parallel with noise reduction cover plate and interval setting；
The edge of upper capacitor cover plate and noise reduction cover plate is fixed by cover sidewall；Form one between upper capacitor cover plate and noise reduction cover plate
The cavity of individual sealing.
Further, it is full of air in cavity.
Further, cavity is vacuum.
Further, it is filled with sound-absorbing material in cavity.
Further, cover sidewall be upper capacitor cover plate to upper overturning formed, the downward flange of noise reduction cover plate formed or
For a single part.
A kind of high-voltage power capacitor unit, including capacitor casing and noise reduction cavity integral cap outlet casing tube；Electric capacity
The top of device casing is provided with roof, and crown center opening is used for installing outlet casing tube；Upper capacitor cover plate sealing welding is in electric capacity
On the roof of device casing.
With respect to prior art, this utility model has the advantages that：This utility model is in the bottom of outlet casing tube
The cavity type cover plate of setting hollow, can effectively reduce the noise sending upwards during power capacitor runs.
Further, constitute the connection not having rigid in the middle part of the upper capacitor cover plate of cavity and noise reduction cover plate, can
Effectively sound insulation.
Further, after cavity evacuation, noise reduction can further be increased.
Further, cavity inside subregion filling sound-absorbing material, can make noise reduction more excellent.
Brief description
Fig. 1 is the structural representation of existing power capacitor.
Fig. 2 is the structural representation of this utility model power capacitor.
Fig. 3 is the amplification view in A portion in Fig. 2.
Specific embodiment
Refer to shown in Fig. 2 and Fig. 3, a kind of high-voltage power capacitor unit of this utility model, including capacitor casing 1 He
Noise reduction cavity integral cap outlet casing tube 2.

21 and noise reduction cover plate 22.Upper capacitor cover plate 21 passes through the bottom that rolling is fixed on two insulators 26.Respectively roll on two insulators 26
Pressure is connected with a flange 23, flange 23 and upper capacitor cover plate 21 interval setting, and respectively there is a section of insulator 26 centre.Noise reduction lid
Two through holes are had on plate 22, this two through holes are enclosed within companion flange 23 periphery, and weld with flange 23 so that upper capacitor cover plate
21 and interval settings parallel with noise reduction cover plate 22.The edge of upper capacitor cover plate 21 and noise reduction cover plate 22 is welded by cover sidewall 24
Connect fixation.Form the cavity of a sealing, for completely cutting off capacitor to upload between upper capacitor cover plate 21 and noise reduction cover plate 22
The noise going out.It is not rigidly connected between upper capacitor cover plate 21 and noise reduction cover plate 22, is connected by insulator, noise isolating performance is excellent
Good.It is air in cavity, or evacuation, or filling sound-absorbing material, noise isolating performance is more preferably.Upper capacitor cover plate 21 seal weld
It is connected on the roof 12 of capacitor casing 1.
Further, cover sidewall 24 is upper capacitor cover plate 21 to upper overturning formation, the downward flange shape of noise reduction cover plate 22
Become or be a single part.
