Analysis of the fault causes of the conductive slip ring

The fault and failure of the sliding ring will directly lead to the failure of the equipment. For the fault analysis of the sliding ring, it is necessary to understand the sliding ring from the structure and working principle. Most of the sliding rings in the market are, including carbon brush contact, single filament contact and brush beam multi-point contact. The internal components are composed of sliding ring body, brush support, brush, bearing, bearing end cover, etc. The key to the quality of the sliding ring is the rotation accuracy of the sliding ring body, the electric contact pressure of the brush and the ring body and the electric contact material.

Slip ring fault mainly has rotation, poor contact, contact failure, leakage, short circuit, signal interference, signal packet, there are many reasons for these problems, may be due to the design itself problems, but the ring itself in use after a period of time, may also be due to the contact surface wear, use environment abnormal slip ring fault. We need to check and test the abnormal conductive loop, open the shell of the loop, check the abnormal point of the loop, analyze the cause of the abnormality, in order to find a solution to the problem.
