Conductive slip ring is a very important part in automatic control system. It is responsible for providing energy and information transmission channel for the system. So its performance parameters and quality as well as the factors affecting quality, quality control becomes particularly important. Its performance is directly related to the stability of the whole system operation, or even normal operation. The following is shenzhen Jiujiang Yingzhi technology on the main electrical performance of slip ring do some simple introduction. So that we can be more comprehensive in the selection of slip ring evaluation and selection.
First, the electrical contact performance of slip ring The role of slip ring is to transmit power and signal by electric connection, the first choice must have excellent electrical contact performance. As the contact mode of the conductive ring is electrical sliding contact, it needs to have wear resistance and electrical corrosion resistance.
Based on the above points, we can find that the conductive slip ring contact needs to have the characteristics of excellent electrical conductivity, good wear resistance and strong electrical corrosion resistance. We know that The best conductivity is Ag, followed by Cu, Au, Al... However, the hardness of these metals is low and wear resistance is poor. In order to make up for this shortcoming, we will add other metal elements to these metals to increase the hardness of materials and enhance the wear resistance of alloy materials according to the actual application requirements. In addition to the performance of the material itself, we also need to pay attention to the smoothness of the contact surface. A rough contact surface or a flaw on the contact surface will affect the transmission effect of the electric slip ring.
Two, the anti-interference of conductive slip ring
The slip ring needs to transmit various signals in the limited space, including high-frequency AC, high-voltage AC, high-current AC and weak dc small signals. Due to the close distance between the rings, various interferences will occur in the signal transmission process, resulting in the distortion of transmitted information. General magnetic interference, we use electromagnetic shielding; Electrical interference, we use electric field shielding, and other ways to reduce interference
The above aspects are the key factors to be considered when we choose conductive rings. If you want to know more about our dynamic and products, please click and browse.
