Introduction to the design of large current conductive slip ring
Today for everyone to share about the large current conductive slip ring product design, because the transmission is a large current device, the first consideration is contact material and brush contact, installation mode, to ensure that the large current conductive slip ring in the working state of the reliable and useful life. The second is the conductive slip ring installation to ensure normal installation. The main components of the conductive slip ring and the electric brush are the key components of the conductive slip ring, the surface of which is used as the electrical contact material, the brush is mainly flaky brush and wire brush, and the brush block composed of non-ferrous metal and graphite. Produce high current density and minimum wear, but the resistance is larger. And the flake brush is more suitable for use in the high Speed environment. Wire-like brushes have excellent elasticity and conductivity.
Combined with the characteristics of all kinds of brushes, the type of brush can be determined according to the current size. The insulator can use PBT as 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 large current of the conductive slip ring, and to fully consider the electrical insulation and the installation and maintenance performance in the design.
Large current conductive slip ring product Advantages: 1, the selection of top-grade graphite alloy; 2, current can be up to hundreds of amps; 3. Compatible with data bus protocol; 4, Super long life, maintenance-free, no lubrication; 5, 360° continuous rotation transmission power or data signal; 6. Compact shape;
Large current conductive slip ring options: 1, access number; 2. Signal and power supply can be transmitted separately or in combination; 3, current, voltage; 4. Conductor length; 5. Connecting terminals; 6. Protection grade; 7, the outlet direction;
We can according to customer requirements of different size of the shaft diameter, different specifications, current size, access number, speed, protection level and other parameters of the slip ring. Widely used in security, automation, power, instrumentation, chemical, metallurgy, medical, aviation, military, shipping, transportation and other electromechanical equipment.
