Points for Attention in Design of Large Current Slip Ring

    With the extensive application of mechanical equipment and automation equipment technology upgrades and enhancements, more and more mechanical equipment use conductive slip ring, because the conductive slip ring can help all equipment to improve the transmission performance of a variety of wires, So that the operating efficiency of equipment greatly improved, so many industries have adopted conductive slip ring to improve the efficiency of mechanical operation, but each mechanical have different requirements of the slip ring, for the reason that each machine's working environment, current, voltage, protection level, Speed and etc is different. Which also contributed to the various types of conductive slip ring appears. For example, high current slip ring is often used in communications and equipments which can avoid the transmission cable will not be damaged by twisting when the system is running. Through the use of conductive slip ring, to ensure the smooth flow of electrical connections.

 

    What are the main points in designing a high-current slip ring? As the transmission of high current devices, the first thing to consider is the contact material and brush contact, installation, in order to ensure high-current slip ring in the working condition of the reliability and service life, the second is the conductive slip ring installation performance can ensure normal installation, because the conductive slip ring needs to be used in marine environment, the shell material must use corrosion-resistant stainless steel. The main components of conductive slip ring ring body and brush as key parts of conductive slip ring, the surface of the plated gold as the electrical contact material, brushes are mainly sheet spring brush and wire spring brush, There is a brush block made of metal and graphite. It produces high current density and minimal wear, but the resistance is large. While the sheet spring brush is more suitable for high-speed environment. The linear brush wire has excellent elasticity and electrical conductivity. Integrated above the characteristics of a variety of brushes, and ultimately by a certain number of brush bundle can be used as the final brush. While the insulator PBT can be used as an insulating material, PBT has excellent dielectric properties, chemical resistance, fatigue resistance and lubrication performance. In the mechanical structure, we need to consider the characteristics of large-current conductive slip ring, in the design of full consideration of electrical insulation, and installation, maintenance performance and so on.

 

    Jinpat Electronics for high-current slip ring performance requirements and the characteristics of certain industries products, ring structure designed into a special empty frame that can be easy maintenance, conducive to heat dissipation. Excellent electrical contact performance, long service life, flexible structure, the use of imported carbon brush production, carrying capacity, less dust, the current up to 2000A per ring, stable and reliable. The unique structural design and high-quality contact materials, So that it has achieved BV classification society certification. Jinpat slip ring can be customized according to customer requirements of different shaft diameter, different specifications, current size, number of channels, speed, protection levels and other parameters of the slip ring.
