Selection and Advantages of Current Collectors

Dairui Electric recommends



A current collector is a device that transfers electrical energy from a sliding wire to electrical equipment through sliding contact. The conductor is made of a special aluminum alloy profile, and its outer protective cover is made of special polyvinyl chloride material, providing safety functions against rain, dust, snow, and electric shock. With a simple structure and easy installation and maintenance, it is widely used for power supply lines of mobile equipment in mines, metallurgy, chemical industry, machinery, docks, and freight yards.

　　

　　Current collector After every 1000 hours of operation, it is necessary to check for loose bolts on the brush holder and conductor caused by vibration during operation, which should be promptly tightened; check the movement of the carbon brush, which should move freely in the brush box without any obstruction.

　　

　　In addition, it is also necessary to check whether the pressure spring has come out of the brush holder or failed to reset after contacting the box; check whether the phase-to-phase resistance meets the requirements of item 3 in the installation requirements, and then use compressed air to blow out internal dust or use gasoline or alcohol to clean the carbon powder between phases. When performing maintenance, the incoming power supply should be cut off to ensure safety!

　　

　　If the equipment is not used for a long time, it is necessary to cut off the incoming power supply and take necessary protective measures. Before reuse, all items should be inspected and maintained according to the maintenance requirements; if the equipment has been submerged in water, drain all accumulated water, and after the equipment is fully dry, check and meet the installation requirements before powering on. After powering on, a trial run should be conducted first, and only after confirming no issues can operation proceed.

　　

　　Selection of current collectors:

　　

　　1. The number of poles can be arbitrarily combined, and can be made into a double-pick type.

　　

　　2. Determine the quantity based on the power consumption of the mobile equipment.

　　

　　3. If used as a control signal, it is recommended to use the double-pick type to ensure transmission accuracy.
