The invention discloses an intelligent built-in electronic arc-blowout bypass type soft
starter, which comprises an
electric motor. The intelligent built-in electronic arc-blowout bypass type soft
starter is characterized in that the intelligent built-in electronic arc-blowout bypass type soft
starter further comprises a singlechip, a
voltage regulator, a current detection protecting module, an open-phase detecting module, a bypass
relay control module, a communication module, a display and a keyboard. The
electric motor is connected with the
voltage regulator; the
voltage regulator is connected with a
data port of the SCM; the display, the keyboard, the current detection protecting module, the open-phase detecting module and the bypass
relay control module are connected with the
data port of the singlechip; the communication module is connected with a communication port of the singlechip, and the bypass
relay control module is connected with the
voltage regulator. The soft start controller has the characteristics of flexible keystroke setting, intuitive
liquid crystal display, various starting manners, current-limiting protection and open-phase protection and the like. A three-phase anti-parallel
thyristor module is adopted by the
voltage regulator, so the control precision is high. Electrically erasable programmable read-only memory(
EEPROM) inside a serial
chip of the singlechip is flexible and reliable in storage, the display is intuitive by adopting the display, and the RS485 communication is flexible, so that the overall controller has a higher performance
price ratio.
