Large Current Integrated Fiber Slip Ring
Large current slip rings is a must-have rotary conductive device on some heavy-duty equipment devices, as the large current is transmitted, which uses a nickel structure to achieve better heat dissipation capacity, and this structure is less suitable for transmission. Signal, however, some large devices are also demand for transmission of signals, which requires the corresponding signaling pathway to the slide ring used.
In the application of a large current slip ring, there is a case that needs to transmit electrical energy and signals to a distance from thousands of meters, and the distance between weak electric transmission is limited, so in order to improve the transmission distance of electrical energy, such large currents The voltages of the slip ring are usually above the kV, while the high voltage will greatly trouble the transmission of weak electric signals. Then, the weak electrical signal transmission distance is very short. If the transmission of long-distance weak electric signals is to be achieved on these devices, the system will make the system very complicated, so that the integrated fiber slide is very good.
From various product cases, many large current slip rings of integrated fiber skull rings, the voltage substantially exceeds 2000V, but its single current is relatively small, only 50 to 100A. Of course, due to the different fiber types, the fiber skull ring used in large current slides that support current signal long-range transmission is basically a single-mode fiber skull ring, and single-mode fiber skull rings and high The large current slide of the voltage is integrated, and the signal and electrical energy can be easily transmitted to 5,000 meters.
In addition, industrial production often faces some extreme production environments, so in order to ensure that equipment can be smooth and safe to operate in these common extreme production environments such as high temperature, dust, moisture, and achieve both guaranteed efficiency. It is also possible to take into account the purpose of production safety, which will be more stringent for electronic components, and the requirements for electronic components quality and technical parameters will be more stringent.
The latest large current slip ring of JINPAT Electronics is designed for the use of pulverized coal stacking machines and high dust environments, the entire fiber slip ring is vertical mounting, from rotor, stator, base three parts Composition (as shown in the figure below); in order to ensure security, the rotor waterproof joint is provided on the side of the rotor, and the bottom is provided with a stator wiring waterproof joint. The pressure resistance is 2500 Vac @ 50Hz (P) and 300Vac @ 50 Hz (S) protection The level reached the IP66 level, which can reach 10 rpm at the ambient temperature of -20 ° C - + 60 ° C, relative humidity ≦ 90RH, the speed is up to 10 rpm; not only, even under this condition, the light current production of JINPAT Electronics integrated optical fiber The slip ring still has a plug-in loss value of less than 4dB, and the insertion loss change value is controlled in 2DB and so on (detailed technical specifications as below).
At present, the slip ring is widely used in industrial application scenarios such as coal yards. If there is a manufacturer, you are welcome to come to consult, and the crystal will use high quality products and sincere service to get your trust.
