摘　　要：抽油机依靠电动机通过皮带传动带动驱动轴运行,皮带断裂后,抽油机停止工作,此时电动机仍处于空载运行状态,皮带断裂后目前只能靠日常巡回检查发现,并采取人工方法拉闸断电处理。电动机空载运转,特别是夜间可能长达十多个小时,造成了很大的能源浪费,也增加了工人的劳动强度。根据油田生产管理需要,研制了电动机空载运转自动断电装置,文中详细地介绍了该装置的技术原理、技术指标、解决途径以及实现方法,并对应用后的效果及节能情况进行了经济效益评价。目前,该装置已在5口抽油机井上应用,月度节电约5400 kWh。该装置的研制与应用,解决了当前油田电动机空载运转这一管理难题,为抽油机节能降耗提供技术支撑。The pump relies on the motor to drive the drive shaft through the belt drive.After the belt breaks,the pump stops working.When the motor is still in no-load operation state,the belt fault can only be found by daily circuit inspection and be taken manual power cutting method.The no load operation of the motor,especially at night,may last for more than ten hours,causing a great waste of energy and increasing the labor intensity of the workers.According to the needs of oilfield production management,we develops the automatic power off device for no load operation,introduces the technical principle,technical index,solution and realization method of the device in detail,and evaluates the effect and energy of application.At present,the device has been applied on 5 pumping wells,saving 5400 kWh of electricity per month.The development and application of this device have solved the current management problem of no-load operation of oil field motors,and have provided technical support for energy saving and consumption reduction of oil pumping machines.
