First of all, the conductive ring is smoking, which is definitely burned out.
The following two reasons are easy for the conductive slip ring to burn out:
The current is overloaded, and the conductive ring cannot withstand this current and burns internally.
The conductive ring is short-circuited. In this case, the conductive ring is inspected incorrectly when it leaves the factory, causing the slip ring to be short-circuited and burned.
※ So, How to solve the problem of smoke when the conductive slip ring is in use?
If the conductive ring smokes and ignites, the power supply should be cut off immediately and the operation should be stopped. Remove the conductive ring and send it back to the factory for maintenance. Because there are no internal accessories, there is no way for individuals to repair it.
※ DO YOU KNOW THE WIND POWER SLIP RING?
In the field of wind power generation, the service life of wind turbines can basically reach twenty years. In the first few years of use, the entire fan system begins to age, and not all technical maintenance personnel can do the daily maintenance of the fan system, let alone some unplanned maintenance that requires very rich experience. As a result, the normal operation and even the service life of the wind power system will be affected. After years of experience, JARCH Electromechanical can now explain the superior performance of conductive slip rings for you.
Monofilament precious metal brushes improve the shortcomings of composite metal brushes, with small wear debris, small size, good signal transmission stability, but very limited bearing capacity. Fiber brushes are designed with multiple metal fibers, which maintain multiple points of contact with the metal ring body, and have excellent electrical conductivity and high current density. And the environmental sensitivity requirements in the fan housing are much lower than in other types of contacts.
Reducing the maintenance requirements of wind turbines is an important measure to reduce the operational risk of wind power systems. As an important part of the wind power system, the wind power slip ring is installed in the hood of the wind turbine to provide pitch power and the transmission of various control signals when the wind turbine is rotating. Since the brushes of the conductive slip ring are initially designed with a conductive block of composite metal, in order to avoid the wear of the slip ring ring body during operation, the brushes are preferentially worn in the design. Due to the service life of the brush itself and the conductive powder generated during wear, which seriously affects the normal operation of the wind power system, especially since the powder is more sensitive in a humid environment, so it needs to be cleaned regularly. About 60% of the wind power slip rings on the market use composite metal brushes, about 30% use monofilament precious metal brushes, and nearly 10% use fiber brush brushes.
