Definitions
- the invention relates to a capacitor device, comprising a plurality of capacitor elements, each comprising at least two electrodes and at least one dielectric disposed between the electrodes.
- Electrical capacitor devices typically include a plurality of electrical capacitor elements arranged in rows or stacks. Each capacitor element is formed of at least two electrodes and we ⁇ tendonss arranged between the electrodes Dielekt- rikum. Such capacitor devices are used for example as power capacitors in the field of power engineering for the transmission and distribution of electrical energy in or between power distribution networks.
- the invention is based on the problem of providing a contrast improved capacitor device.
- the problem is solved by a capacitor device of the type mentioned which there ⁇ by distinguished in that arranged between at least two adjacent capacitor elements, a visco-elastic damping element is disposed at least.
- the inventive principle is based on the idea of a arranged a plurality of, ie capacitor means typically formed several dozen, Benach ⁇ discloses arranged capacitor elements adjacent means between the adjacent arranged capacitor elements or groups capacitor elements arranged viscoelastic damping ⁇ elements in certain respectively determined disposed under ⁇ units to subdivide ,
- a subunit consists of a capacitor element or a group of several be ⁇ nachbart arranged capacitor elements.
- the size, ie the number of capacitor elements included in a subunit, is given by the choice of the positioning of the damping elements between the typically rei ⁇ hen- or stack-like arranged capacitor elements.
- the number of corresponding, belonging to a subunit capacitor elements is to be chosen in particular taking into account the total number of capacitor elements and the related ⁇ training option corresponding mechanical vibrations through the capacitor device.
- the number of corresponding capacitor elements belonging to a subunit, ie the size of corresponding subunits is arbitrary.
- the type of arrangement or the order of the subunits determining choice of the sequence of corresponding subunits is given by the choice of the positioning of the damping elements between the capacitor elements.
- a regular sequence or arrangement of corresponding elements between the damping elements Kondensatorele ⁇ a uniform distribution of the
- Condenser device formed in corresponding subunits to be.
- a regular sequence of corresponding subunits is given, in particular, if at least one damping element is arranged between all capacitor elements arranged directly adjacent to one another.
- An irregular sequence or arrangement of corresponding damping elements accordingly forms an uneven distribution of the capacitor device into corresponding subunits.
- Subunits include.
- the viscoelastic damping member may be disposed over the entire surface Zvi ⁇ rule two adjacently arranged capacitor elements, making it the immediately adjacent surfaces each completely covered. It is conceivable, depending ⁇ but also that the damping element directly aneinan- the adjacent faces corresponding capacitor elements only area or partially.
- one or more strip-shaped damping elements can cover the directly adjoining surfaces of corresponding capacitor elements in each case and in particular only in certain areas in total.
