Common problems in high speed slip ring applications

A high speed slip ring is a device that helps a rotating device transmit a current signal as it rotates. It helps the rotating device transmit energy.More and more equipment began to use the slip ring because of its larger role, and the quality requirements are becoming more and more stringent.Accordingly, want to choose technology good manufacturer, the product that produces different class.However, there are still some problems in the actual use of any high-speed sliding ring, such as the following:


 

First one , too much interference.High speed slip ring is a device used to transmit power and signal, and the interference between power and signal can be divided into internal interference and external interference.Therefore, it is necessary for the designer to know clearly the type of signal.For special signals, special wires must be used for internal and external shielding.For the formed high speed slip ring, if the signal of the slip ring is found to be interfered, the external conductor can be shielded by itself.If this is still not resolved, the internal structure of the slip ring can only be redesigned.

 

The second is short circuit of high speed slip ring.Normally, the dust proof and water-proof grade of the slip ring is IP54.In the absence of additional protection, some customers place it in places with high waterproof requirements, causing water to enter the slip ring, resulting in short circuit and failure inside the slip ring.Not only that, when the high speed slip ring is used for a period of time, there will also be a short circuit problem, which may be the service life of the slip ring, or the slip ring is overloaded and burns out.Generally speaking, if a new slip ring shorts, it is due to a problem with the insulating material inside the slip ring, or a direct short circuit between the brush lines, broken wires, etc.

 

The last, slip ring overload burn.The larger allowable current of the high-speed slip ring is its safe operating current value, which is mainly determined by the comprehensive factors such as the contact area of the conductive ring and the brush, the pressure and speed of the brush and the contact surface.If this value is exceeded, the slip ring may become hot if it is very light.If it is very heavy, the contact surface will ignite and even form a welding point between the brush and the conducting ring.Although some safety considerations are taken into account in the design phase of the high speed slip ring, it is recommended that customers provide the slip ring manufacturer with the large current actually used.In addition, there are still some problems in the use of the slip ring, such as unsmooth rotation and unprotected circuit.
