Embodiment Construction

[0064] figure 1 Shown is a slip ring SR with a sliding track SB, a power supply line D, sliding contact elements SE1 and SE2, sliding contacts SK1 and SK2, a measuring device MV and a determination unit EE. The slip ring SR has a slide track SB and is rotatable relative to the feeder D. At the feed line D, two sliding contact elements SE1 and SE2 are arranged. Each of the two sliding contact elements SE1 and SE2 is designed as a brush, for example a carbon brush.

[0065] Each of the two sliding contact elements SE1 and SE2 is connected to the feeder D by means of a spring element and a contact pressure adjustment device, wherein the contact pressure adjustment device is designed to adjust the contact pressure of the brush on the sliding rail SB. One end of the spring element is fixedly connected to the feeder D. The other end of the spring element is fixedly connected to the brush. The spring element can have, for example, an elastic metal strip which is clamped in the re...

Abstract

A computed tomography device includes a slipring for rotational transmission and a feed line. The slipring is arranged to be rotatable relative to the feed line. Two sliding contact elements are further included, forming sliding contacts between a slideway of the slipring and the feed line, the two sliding contacts being connected in parallel with one another and electrically conductively connected together via at least one portion of the slideway and via at least one portion of the feed line. The computed tomography device also includes a measuring apparatus, configured to detect a measured value dependent on a resultant inductance between the two sliding contact elements; and a determining unit, configured to determine an operating state of the two sliding contacts based upon the measured value.

Description

technical field [0001] The invention relates to a computed tomography system and a method for determining the operating state of a sliding contact on a slip ring for rotational transmission in a computed tomography system. Background technique [0002] For rotational transmission in computed tomography systems, slip rings with one or more sliding contacts are often used. The sliding contact can be realized, for example, in the form of carbon and / or brushes. Abrasion, contamination and / or special stresses can cause sliding contacts to fail. A failed sliding contact can cause arcing, which can damage the slip ring and, in particular, can lead to an interruption of inspections by means of computed tomography equipment. As the sliding contacts wear over time, they must be replaced periodically. [0003] In general, damage to the sliding rails caused by arcing is avoided by replacing the sliding contacts very early. This leads to unnecessarily high maintenance costs, since th...
