Abstract

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.

Description

technical field [0001] The invention relates to an intelligent built-in electronic arc-extinguishing bypass type soft starter. Background technique [0002] High-power three-phase asynchronous motors are widely used in various industrial fields due to their simple structure and reliable performance. When the high-power motor is directly started, it will generate a large impact current on the power grid, and the mechanical transmission parts will fail due to the impact torque. Moreover, direct starting is easy to burn out the windings, and it is not allowed to start directly with load. Therefore, people continue to improve the starting technology of three-phase asynchronous motors. The soft start technology has developed from the initial stator series resistance, star-delta start, and auto-coupling decompression start to the modern intelligent soft start controlled by thyristor voltage regulation. The traditional soft start control system has complex structure, numerous co...
