三、电滑环的绝缘性能
绝缘性能是滑环安全性能，包括环道间绝缘、环道与外壳间绝缘，导线间绝缘、环道与导线间绝缘、环路和导线与外壳间的绝缘，绝缘性能取决于绝缘材料，也取决于滑环的生产工艺和使用环境，不同的生产工艺，我们所采用的绝缘材料的材质和形态都不一样，通常我们需要考虑绝缘材料的绝缘性、耐老化性、吸水率、防火等级、耐高温、以及机械强度等方面。针对不同的应用选择合适的绝缘材料至关重要。
以上几个方面是我们在选择导电环时，重点需要考虑的几个因素。
The conductive slip ring is an important part in the automatic control system, which is responsible for providing energy and information transmission channels for the system. Therefore, its performance parameters and quality, as well as the factors affecting the quality and quality control become particularly important. Its performance is directly related to the stability of the whole system, even normal operation. Here is a brief introduction to the main electrical performance of the slip ring by Hangzhou Baixuan power technology. So that we can make a more comprehensive evaluation and selection in the selection of slip ring.
1、 First, the electrical contact performance of slip ring
The function of slip ring is to transmit power and signal by electric connection, so it must have excellent electric contact performance first. Because the contact mode of the conductive ring belongs to electrical sliding contact, it needs to have wear resistance and corrosion resistance.
Through the above points, we can find that the conductive slip ring contact needs to have excellent conductivity, good wear resistance and strong resistance to electric erosion. We know that the best conductivity is AG, followed by Cu, Au, al But these metals have low hardness and poor wear resistance. In order to make up for this defect, according to the actual application demand, we will add other metal elements to these metals to increase the hardness of materials to enhance wear resistance, alloy materials. 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.
2、 Anti interference of conductive slip ring
The slip ring needs to transmit various signals in the limited space, including high-frequency alternating current, high-voltage alternating current, large current alternating current and weak small direct current small signals. Due to the close distance between the rings, various interferences will occur in the process of signal transmission, resulting in the distortion of the transmitted information. For general magnetic interference, we use electromagnetic shielding; for electric interference, we use electric field shielding to reduce interference.
3、 Insulation performance of electric slip ring
The insulation performance is the safety performance of slip ring, including the insulation between the rings, between the rings and the shell, between the wires, between the rings and the wires, between the rings and the shell. The insulation performance depends on the insulation material, and also depends on the production process and the use environment of slip ring. Different production processes, the materials and shapes of the insulation materials we use are different Often we need to consider the insulation, aging resistance, water absorption, fire rating, high temperature resistance, mechanical strength and so on. It is very important to choose suitable insulating materials for different applications.
The above aspects are the key factors we need to consider when choosing the conductive ring.
