The most basic conductive slip rings must be explosion-proof. The slip rings used in steelmaking must be resistant to high temperature. All conductive slip rings in electroplating industry must be able to withstand excessive current
The conductive slip ring is a method for connecting 360 degree rotators, transferring energy and signals, which solves the problem of gas electricity mixing in the rotating part. With the further implementation of China's new energy policy and emission reduction policy, as well as the strong support and implementation of the country for the wind power industry, small wind power conductive slip rings have been increasingly used in the wind power industry.，
The conductive slip ring is a device that uses the sliding or rolling contact, electrostatic coupling or electromagnetic coupling of conductive parts to transmit electrical signals and energy to the rotating parts and static parts of the antenna base. Transmission elements, measuring elements and control elements on rotating parts must transmit control signals to the machine room and supply power to them.
The slip ring determines the current value that the slip ring can safely pass according to the area of the copper ring, the contact area of the brush, the size of the wire diameter, etc. If this value is exceeded, it is easy to short-circuit the outgoing line and damage the inner part of the conductive ring. When purchasing the slip ring, the manufacturer must be informed of the current to pass through to avoid many problems.
Special attention shall be paid to these two points when designing electric slip rings and high current slip rings. High current conductive slip rings also have high requirements for voltage variation. When the current is particularly large, it is easy to produce an electric fire effect, which will have a great impact on the life of slip rings, material oxidation, etc.
