With the extensive application of the mechanical equipment and automation equipment technology upgrade and enhanced functionality, a growing number of machinery and equipment adopted conductive slip ring, Because of mechanical equipment used in the conductive slip ring can help improve the performance of the wire transfer for mechanical equipment operation efficiency greatly, so a lot of industry of machinery are conductive slip ring is used to improve operating efficiency, But each machine for the slip ring requirements are different, because each mechanical work environment is different, current, voltage, different levels of protection, rotation speed, etc. Which also contributed to the emergence of various models, types of conductive slip rings. For example, high current slip ring is often used in communication equipment and equipment, to avoid the system in operation, the transmission cable will not be broken due to twisting. Through the use of conductive slip ring, to ensure the smooth electrical connection. So how do we design a high current conductive slip ring?
As the transmission of a large current device, the primary consideration is the contact material and brush contact, installation, to ensure that the high current conductive slip ring in the working state of contact reliability and service life. secondly by the installation performance of conductive slip ring to ensure the normal. As the high current conductive slip ring needs to be used in seawater environment, its shell material must use corrosion-resistant stainless steel. The main components of the conductive slip ring ring and brush for the conductive slip ring of the key components, the surface of the use of thick gold as the electrical contact material, the brush is mainly sheet spring brush and linear spring brush, and A brush made of metal and graphite
The main parts of conductive slip ring ring body and brush as key components of conductive slip ring, its surface using thick gold plating as electrical contact materials, the brush has a plate spring brush and linear spring brush and made of metals, graphite block, Which produces high current density and minimal wear, but the resistance is large, The flake spring brush is more suitable for high-speed environment. The linear wire has excellent elasticity and electrical conductivity. Combined with the characteristics of all kinds of brushes, finally adopted by a certain number of brushes as the final brush. The insulator can use PBT as an insulating material, PBT has excellent dielectric properties, chemical resistance, fatigue resistance and lubrication performance. In the aspect of mechanical structure, it is necessary to consider the characteristics of the conductive slip ring of the large current, also need to fully consider the design of electrical insulation, and installation, maintenance performance and so on.
