Detailed description of the invention
The embodiment combined in accompanying drawing is further described by this utility model below:
As shown in Fig. 1 ~ 5, this utility model mainly includes power capacitor casing 3 and power capacitor fuse 4, power capacitor fuse 4 it is provided with in power capacitor casing 3, in power capacitor casing 3, it is provided with at least one installation site vibration damper plate 1 flexibly, absorbs the noise within power capacitor casing 3 by vibration damper plate 1.
As it is shown in figure 1, the steel plate materials that vibration damper plate 1 uses 1 ~ 2.5mm thickness makes, the length, width and height of vibration damper plate 1 are designed according to power capacitor core size.Vibration damper plate 1 outer surface coated insulation layer, and be connected with power capacitor fuse 4, for fixed potential by wire.
Vibration damper plate 1 is internal is provided with sealed damping chamber 2.Damping chamber 2 can use air type damping chamber or vacuum type damping chamber, air type damping intracavity portion to be full of the air of normal atmosphere, and vacuum type damping intracavity portion evacuation processes.Compared with air, vacuum state has higher obstruction ability for sound wave, therefore absorbs noise result more preferable.
During power capacitor runs, element issues raw mechanical vibration in the effect of electric power and electromagnetic field, produces noise.Noise is the strongest in two big faces of element, is reflected on power capacitor body as upper and lower two bottom surface noises maximum.
In embodiment one as shown in Figure 2, between power capacitor casing 3 and power capacitor fuse 4 upper surface, place vibration damper plate 1.
In embodiment two as shown in Figure 3, between power capacitor casing 3 and power capacitor fuse 4 lower surface, place vibration damper plate 1.
In embodiment three as shown in Figure 4, vibration damper plate 1 is placed inside power capacitor fuse 4, vibration damper plate 1 is placed in parallel with the power capacitor fuse 4 within power capacitor, vibration damper plate 1 has, to vibrations and the noise of power capacitor fuse 4, the effect absorbing and hindering, it is achieved thereby that reduce the purpose of power capacitor noise.
In embodiment four as shown in Figure 5, between power capacitor casing 3 and power capacitor fuse 4 upper surface, between power capacitor casing 3 and power capacitor fuse 4 lower surface, inside power capacitor fuse 4, all place vibration damper plate 1, thus improve damping effect.
This utility model simple in construction, compact, reasonable, manufacturing process is simple, does not affect the structure of power capacitor inner core, does not affect the key property of power capacitor, and manufacturing cost is relatively low；Power capacitor noise can be substantially reduced, flexible and convenient to use.
