Description
Technical field
The present invention relates to the high-voltage power capacitor cover plate, be specially a kind of high-voltage power capacitor integral type sound insulation cover plate.
Background technology
Along with developing rapidly of China's HVDC Transmission Technology, power capacitor has also obtained a large amount of application in DC transmission engineering, but in the DC transmission engineering of having moved, it is outstanding that noise problem becomes, and also had influence on surrounding environment and resident.In the numerous equipment of direct current transportation, ac filter capacitor and shunt capacitor are one of main sources of direct-current transmission converter station noise, because the pylon of DC filter capacitors is higher, the noise problem of DC filter capacitors also can not be ignored.
The noise of capacitor is because capacitor plate under the effect of applied voltage, produces regular mechanical oscillation propagates into and form in the air.This noise is said from propagation property and is belonged to compressional wave, that is to say that the direction of propagation of capacitor noise is consistent with the direction of vibration of pole plate, and namely the noise of capacitor is mainly propagated along the direction of bottom and outlet casing tube, and the noise of side is then so not outstanding.
In order to solve the noise problem of capacitor, China Patent No. ZL 2,009 2 0164706.6 discloses a kind of
Low noise capacitor device falls; China Patent No.ZL 2,008 2 0104113.6
A kind of capacitor device with noise absorption cover is disclosedThis noise reduction measure of taking in the capacitor device structure, generally be at capacitor group end face installing noise absorption cover, or between capacitor and mount support, take noise reduction measure, with to take noise reduction measure on the single capacitor different, although the noise that reduces whole capacitor device is had certain effect, effect is also not obvious.
Noise reduction measure for original single capacitor, Chinese patent ZL 2,008 2 0300691.7 discloses a kind of low-noise high-voltage power capacitor unit, the noise reduction measure that this low-noise high-voltage power capacitor unit adopts, mainly be that center to capacitor internal is fixed wrapping, and the employing sound-absorbing material, low noise effect is fallen thereby reach.Secondly some producers are also arranged at the end of capacitor unit and cover and try every possible means, adopt Di Hegai double-deck or thickening, for the material of the thickening end and lid, the effect of noise reduction is not so obvious; And adopt double-deck Di Hegai, every layer Di Hegai all to need separately and shell welds, increased the workload that shell welds, and if loam cake do not adopt seal weld, might play amplification to the noise of capacitor.
Summary of the invention
The objective of the invention is for overcoming the deficiencies in the prior art, and provide a kind of high-voltage power capacitor integral type sound insulation cover plate, the sound insulation cover plate of this structure can be directly welded in the capacitor case, noise isolation effect to the capacitor casing direction is obvious, reduce the noise of DC transmission engineering power capacitor sleeve pipe direction, thereby reach the effect that reduces whole capacitor device noise.
The technical scheme that realizes the object of the invention is:
A kind of high-voltage power capacitor integral type sound insulation cover plate, comprise upper cover plate and lower cover, upper cover plate is peripheral downward bending structure, lower cover is up bending structure of periphery, be connected as a single entity by peripheral bending part welding between two cover plates, and the formation cavity, be provided with circular hole at upper cover plate, be connected with the casing flange place of lower cover.
Described circular hole is by the mould one-shot forming, and its height is determined according to different casing sizes, welding requirements and cavity volume with size dimension, to obtain different cavity volumes, received different soundproof effects.
Described lower cover is the crimping cover plate of integral type for pressing embedding with sleeve pipe.
Sealing compound can be filled in the junction of described casing flange and circular hole, with the reliability of further raising welded seal, has also increased the aesthetic property of integral type sound insulation cover plate simultaneously.
Can fill acoustic damping materials as required in the described cavity, to increase sealing effectiveness and soundproof effect, further reduce noise, improve soundproof effect.
Described acoustic damping materials are prior art.
Advantage of the present invention is:
1, after the upper cover plate of this integral type sound insulation cover plate and lower cover periphery and annulus place carry out seal welding, form integral structure, can directly carry out the leak test check in sleeve pipe producer, can also again hunt leak separately when the user uses, at utmost avoid integral type sound insulation cover plate leakage problems.
2, this integral type sound insulation cover plate, use simple, convenient, can be directly and capacitor case weld, and the use of common cover does not have difference.
3, this integral type sound insulation cover plate soundproof effect is good, can obtain cavity volumes different between the upper and lower cover plates according to different annulus Height Adjustment, obtains different soundproof effects, and the scope of application is extensive flexibly.
4, this integral type sound insulation cover plate scope of application is extensive, can be applied to high and cold, high altitude localities, can not affect its serviceability and result of use.
5, this integral type sound insulation cover plate is reasonable in design, and is simple in structure, and soundproof effect is good, can use on a large scale in high-voltage power capacitor, and economy is higher.
6, this integral type sound insulation cover plate is not subjected to the restrictions such as condenser voltage grade, capacity and capacitor type, not only can be used for general conventional high-voltage power capacitor, also can be applicable to the high-voltage power capacitor in the DC transmission engineering, sealing, soundproof effect is good.
