High current conductive pulley is the main transmission of 50A-50A above the large current pulley. In a Conductive Slip Ring, the signal is different from the ordinary small current conductive slip ring. We know that the overcurrent is very large and it fluctuates greatly in terms of contact resistance and resistance change rate. As long as the contact resistance is high, power = current squared * resistance has a high contact resistance. Therefore, special attention should be paid to these two points when making and designing high current conductive slip rings. Secondly, the high current conductive pulley has a very high requirement for voltage change, especially when the high current is easy to produce electric fire effect.
The reliability and service life of the high-current conductive loop in operation are guaranteed, mainly considering the contact material and brush contact and installation method, secondly, to ensure that the installation performance of the conductive ring can be installed normally because the high-current conductive loop needs to be used in the seawater environment, its shell material must be corrosion resistant stainless steel Ring body and brush is a major part of the conductive ring, are key components of the conductive ring, surface adopts thick gold plated as electrical contact materials, brush is given priority to with flake spring brush and linear brush Spring brush brush brush with metal and graphite in high current density and minimum wear and tear, but the resistance high single spring brush is more suitable for use in high speed environment linear brush has excellent electrical conductivity and flexibility By combining the characteristics of all kinds of brush, you end up with a certain number of brushes can be made with the final brush PBT can be used as a dielectric insulating material, PBT, it has excellent dielectric properties chemical resistance fatigue resistance and lubricity For mechanical structure, want to consider the characteristics of the conductive circuit of large current, fully considering the electric insulation performance of installation and maintenance, etc.
