摘　　要：液态软启动技术具有启动性能好 ,可调性高、适用范围广等特点 ,广泛应用于各类拖动电动机的启动与保护 ,特别是应用环境恶劣、启动困难的场所。电泵采油系统大多在野外深井中运行 ,采用工频全压启动方式 ,由于地下工况的变化 ,经常因电流过大而烧毁电机 ,对电泵机组及电器设备造成极大的损害 ,且维修困难 ,维护费用高。采用液态软启动技术有效地解决了电泵现场应用中的难题 ,并达到节能补偿的目的 。With the character of best starting property, wide adjusting range and wide applicable fields,the liquid soft starters that have been widely used in starting and protecting the electric motors, specially for the motors which were used under worse environment with great difficult to start on. The oil pump system drive by electric motor is used to work in field and deep under the oil well and is usually destroyed by crest current because of the change of work condition. This would be great hurt to the motor pump units and other equipment of electric.Since the difficulty and high cost to repair. The liquid soft starter will be widely used in this field to resolve the problem effectively.
