摘要
抽油机电机控制箱是80年代初期开始研制和使用的，它的主要作用去控制和保护抽油机电动机。作为一种安装于户外的低压电器控制设备，它的各项技术指标必须符合GB7251-87《低压成套开关设备》和有关技术文件的要求。在正常情况下，应能保证电机的起动、运行和制动；出现故障时，它应保证电机不被损坏。电控箱的检测应按GB9466-88《低压成套开关设备基本试验方法》的规定和有关技术文件的要求进行。
The electrical machine controller of the pumping unit was used and reearched at the beginning of the 80’s. Its main function was to protect the motor of the pumping unit. As outdoor low-voltage electrical apparatus control equipment, the technical index must be in accordance with the requiement of GB 725-87 Low-Voltage complete set of swith equipment and the other technical documents. Under the condition of normal use, the requirement should guarantee the start, operation and stop. In case of failure, the requirement should keep the motor from damaging. The Testing of Electrical Controller should be in accordance with GB 9466-88 Low-Voltage Complete Set Equipment Experiment Method.
