Abstract
An arrangement has an electrical device with two or more electrical contact points. A fluid-based reference potential connecting device is suitable for connecting the electrical contact points to a reference potential. The fluid-based reference potential connecting device has an annular fluid line which connects the contact points in series, and, when a fluid flows through the fluid line, the fluid successively wets the contact points, starting from a starting point, contact point by contact point, along a predefined flow direction.
Claims17
An arrangement, comprising:
- an electrical device having a plurality electrical contact points and having a fluid-based reference potential connecting device configured for connecting said electrical contact points to a reference potential;
- said fluid-based reference potential connecting device having an annular fluid line that connects said contact points in series;
- and
- when a fluid flows through said fluid line, said fluid successively wets said contact points, starting from a starting point, one contact point after another contact point, along a predefined flow direction.
A method for connecting an electrical device, which has at least two electrical contact points, to a reference potential, the method comprising:
- providing a fluid-based reference potential connecting device having an annular fluid line which connects the electrical contact points in series;
- filling the annular fluid line with conductive fluid so as to form a conductive fluid ring;
- and/or
- increasing a conductivity of a fluid in the fluid line by feeding in a substance that increases the conductivity;
- and
- successively wetting the electrical contact points with the conductive fluid and, as a result, electrically connecting the electrical contact points to one another in succession.
