利用星三角启动,大功率电机启动时将定子绕组接成星形,待启动完毕后再切换至三角形连接,能有效降低电机启动电流,减轻对电网的冲击.利用真空接触器、时间继电器、电机保护器等自行设计组装的星三角启动器,具有结构相对简单、保护功能齐全、安全可靠、设备投入较低等优点,满足大功率电机启动需求.
利用星三角啟動,大功率電機啟動時將定子繞組接成星形,待啟動完畢後再切換至三角形連接,能有效降低電機啟動電流,減輕對電網的遲擊.利用真空接觸器、時間繼電器、電機保護器等自行設計組裝的星三角啟動器,具有結構相對簡單、保護功能齊全、安全可靠、設備投入較低等優點,滿足大功率電機啟動需求.

by using the star delta starting, high power motor startup stator windings are connected to the star to be started again, after switching to the delta connection, can effectively reduce the motor starting current, reduce the impact of the power grid. Using the vacuum contactor, time relay, motor protector and design their own assembly star delta starter, with simple structure, complete protection function, safe and reliable, low investment of equipment, to meet the needs of large power motor start.
