Protective Design Of Slip Ring
Slip ring protection requirements including corrosion resistant design, dustproof design, waterproof design, seismic design four areas.
Slip ring corrosion resistant design: the cover layer is applied to the metal surface corrosion of the metal with the surrounding dielectric isolation, from corrosion, metal coating layer, the non-metallic covering layer and chemical treatment layer may be applied generally. To a reasonable selection of materials, to reduce the potential difference of each of the contact between a metal and a metal plating, the general provisions of the potential difference is less than 0.6V. For prone to corrosion fatigue of parts, technical measures should be taken to improve the surface finish. For the metal needs to be done salt spray test, salt spray test is divided into three levels: 48 hours, 72 hours, 96 hours. Domestic general application environment salt spray test not less than 48 hours, the harsh environment of not less than 72 hours; for foreign sales, the general environment salt spray test not less than 72 hours, the harsh environment of not less than 96 hours.
Slip ring dustproof design: devices should be installed in the inlet air filter. Performance evaluation of the air filter should be considered: permeability, absorption of (life), temperature, static pressure losses. Dust levels required to achieve IP3.
Slip ring waterproof design: for outdoor equipment, or other water requirements of use of the environment, the need to use the appropriate waterproof rating based on water requirements. It generally takes up to class IP5.
Seismic design: meet the "anti-seismic performance testing communications equipment Interim Provisions" and anti-vibration requirements.
