Medium-Frequency Control Cabinet
價格：元
This electrical cabinet converts the input three-phase 380V, 50Hz AC power to 510V DC voltage through a three-phase rectifier circuit. After filtering, the circuit, controlled by the main control board and the drive board, inverts the DC to produce a 0.5–2.0 KHz single-phase medium-frequency voltage, which is then sent to the well heating cable via a medium-frequency output transformer. This is used for heavy oil extraction.
Key features include:
1.Simple surface facilities, easy to use and manage.
2.Even wellbore heating with a long heating duration, high thermal efficiency, and adjustable heating temperature to meet wellhead temperature requirements above the crude oil pour point.
3.Simple operation for starting and stopping wells, unaffected by environmental temperature or extended shutdowns.
4.Improved well production efficiency and comprehensive efficiency, increased pump efficiency, and higher cumulative output; reduced non-standard operations such as pump inspections due to power outages or waxing, extending pump inspection intervals.
5.Simple rod string structure, easy operation, and high repeatability and reliability, reducing the load on the pumping unit and improving its working conditions.
