Accuracy: The hardware system adopts the 32-bit high-speed DSP integrated control of TI company, and the software system adopts the phase-locked synchronization control algorithm of independent intellectual property rights to realize the closed-loop automatic tracking control of motor starting process, which guarantees the stability and accuracy of equipment starting and running state at all times.
Fast: The speed of the DSP control system is above 150 MHz, and the response time of current regulation is 20 ms.
Intelligence: Unique large screen human-machine touch interface interactive function, through the interface easy to set start and protection parameters, state information animation settings, operators can quickly understand the motor operation status and equipment fault information, motor start, real-time and effective monitoring of motor operation, dynamic display of current and voltage curve, while querying historical curve records;
Communication: Intelligent docking of backstage or cloud platform can be provided to improve the level of automation management.
Energy saving: High voltage thyristor chopper voltage regulation loss of main device of solid-state soft starter is small, power loss of soft starter in starting process is less than 1% of rated power of equipment, and operation process is basically lossless.
All-round: strong adaptability and frequent start, a kind of solid-state soft-start device can be applied to different motors with the same voltage grade and rated current, which is convenient to realize the on-site working conditions of more than one tractor motor. The solid-state soft-start device adopts low-power control technology, which can start more than five times per hour to meet the needs of frequent soft-start under different working conditions.
Safety: Direct-drive trigger thyristor is used between low-voltage control system and high-voltage trigger system. Signal conversion is completed by electromagnetic induction, which completely solves the insulation problem of signal transmission channel and is safe and reliable.
