Submersible oil electric pump control device

The utility model relates to a submersible oil electric pump control device. The device belongs to the technical field of petroleum mining manufacture submersible oil electric pump automatic control. The device comprises a voltage sensor, a current sensor, an analog quantity input module, an analog quantity output module, a CPU module, a storage card, a touch screen and a frequency converter. The device can completely replace the manner combining traditional submersible oil electric pump control device and a current recorder. The device enables all control protective functions needed by operation of the submersible oil electric pump, and records operating current data in the storage card of a programmable controller in a real-time manner. The device is flexible in structure, high in anti-interference capability and high in reliability. The device is convenient in upgrade and expansion. Control scheme changes can modify programs on line instead of changing hardware wiring. An RS485 communication interface and an analog quantity input channel are reserved to facilitate other parameter monitoring and oil well remote monitoring. The device utilizes the touch screen as a man-machine interface that is simpler, more abundant and more attractive, so that the device has greatly improved expandable and maintenance performances.
