Chinese show motor soft start SZRJ1 Product details: SZRJ1-5000 type Chinese display motor soft start device is an advanced microprocessor core sixteen high-power thyristor control module, three-phase AC induction motor (squirrel cage) soft start and soft stop function relay, while overload, phase loss, overvoltage, undervoltage protection and a number of optional features. The products are mainly supporting the use and complete control cabinet, use must be connected with the corresponding specifications of the bypass contactor. Product specifications covering 5.5KW-600KW three-phase AC induction motor (squirrel cage), is widely used in all industrial sectors of electrical transmission equipment metallurgy, oil, fire, mining, petrochemical, and other traditional music song Y- △ starter relay, reactance starter, auto decompression starter ideal replacement products. This product performance in line with the relevant provisions of GB14048.6-98. QD-MF series of high-voltage inverter Product details:? Features flexible loop control sensorless vector control to achieve a stable speed control. The need for precise speed control or high starting torque, speed sensor can be used in closed-loop vector control. ? High-load input power transformer secondary winding multiplexed, reducing harmonic current power supply pollution, meet the most stringent IEEE 519 standard. No need to install power factor compensation device and harmonic suppression device power-off delay relay, the "Perfect Harmony Drive" in the true sense. ? Quality-driven multi-level PWM motor control, providing sinusoidal current output. Common mode voltage and dV / dt is small, motors, cables, no special requirements, frequency transformation of the old equipment, no need to replace the motor. ? Higher harmonic components of the ideal mechanical power output current contains extremely small, pulsating torque shaft system resulting influence is negligible. ? High efficiency basic sinusoidal output current, reducing the motor high harmonic losses. Input transformer primary winding high harmonics is small, the system efficiency of over 97%. Without additional output transformer, eliminating the losses arising therefrom. Multi-level PWM control, cut its high frequency IGBT switching losses. ? High-power diode full bridge rectifier uses without power factor compensation relay model, can reach more than 95%. ? High reliability IGBT inverter: The 1700V high voltage IGBT, at the same time reducing the number of components, improving the reliability of the system. Strong anti-interference: using optical fiber isolation between the control system and the power unit, safe and reliable. Strong self-diagnostic capability: the system in a timely manner all kinds of emergencies to make an accurate early warning protection.
