Jiangxi SCKR-260kW internally bypassed soft starter, three-phase line soft start

Jiangxi SCKR-260kW internally bypassed soft starter, three-phase soft starter online production company FJR series soft starter after years of application and continuous improvement, both in terms of performance and reliability are showing remarkable superiority. At present, motor soft starters for various occasions, the power range from 7.5--800KW FJR series motor soft starters, its control circuit INTEL company's 8797 16-bit microcontroller to control the core, the main circuit using three pairs of anti-parallel SCR composition phased form, by controlling the size of its conduction angle, to change the output voltage of the purpose, in order to achieve a smooth start AC motor soft starter has the following characteristics: 1. The soft starter uses stepless power devices regulator, the motor starting process can achieve a smooth adjustment, compared with the traditional starter, no Y / △ start switching shocks and from the lotus root decompression and magnetic starters compared to the initial moment of the soft starter visual load regulation Therefore the load adaptable. More suitable for heavy-duty starter and large loads. 2. FJR soft starter control circuit chip technology, so that the hardware control circuit structure is simple, reliable and powerful software features rely on to achieve a fully digital device, influenced by the supply voltage fluctuation is small, digital trigger job stability, 6-way trigger pulse signal synchronized to maintain a strict relationship, so that the output voltage stability symmetry, while the circuit with a series of anti-jamming measures, even in harsh electromagnetic noise environment can work. In the control system, also used the fuzzy control theory, the starting process of limiting or ramp control, to avoid starting the process of resonance phenomena may arise. 3. After completion of the starting device, automatically by the bypass contactor motor into the power grid, making SCR life is greatly extended, but also greatly enhance the reliability of the device, not because of the bypass contactor with current switch, so its Almost life depends on its mechanical life, greatly reducing the maintenance cost of the device. 4. Open the user full digital keyboard, making operation simple and convenient compiled. Soft starter products directly from Chinese character display mode, the operation is more intuitive, but also through the RS485 communication interface, using a PC monitor. 5. FJR soft starter also has a passive remote control interface, user-friendly remote control or chain control. 6. FJR soft starter with a soft start and soft stop function, but also the equivalent of a motor integrated protection, has over-current, overload, lack of equal protection, can effectively prevent damage to the motor.
