Problems solved by technology

However, so far, this technology still cannot be effectively popularized and applied on beam pumping units
The main reason is high price and low reliability
Xi'an Petroleum Institute, Northwestern Polytechnical University, Gansu University of Technology and many oilfield research institutes have made unremitting efforts, but so far they have not been able to fundamentally solve the problem

Abstract

The invention is concerned with oil pump high effect and energy saving control tank belonging to electron control technology field. It is fit for oil pump with absolute frequency modulation, press modulation, frequency and pressure control function, owning high capability frequency conversion technology taking 380V / 660V / 1140V three-phase AC pressure. The product relates to main circuit, driving, control, data collecting, feedback, display and electrical source, and the main circuit owns rectifier and inverter, drive exports high effect type SPWM wave to drive IGBT, data collecting collects three-phase current, three-phase voltage, DC, voltage of DC, feedback answers electricity to power network, display uses liquid crystal to display data, the electrical source offers the needed work electrical source. This control tank owns active energy count, over-current protection, over-voltage protection, feedback electricity to power network and give an alarm when it stops, and it is setting fit for oil pump.

Description

(1) Technical field [0001] The invention relates to an electronic control technology, in particular to a high-efficiency and energy-saving control cabinet for a pumping unit. (2) Background technology [0002] For a long time, the energy-saving technology for pumping units has mainly started from three aspects: one is to improve the mechanical part of the pumping unit; the other is to develop different types of energy-saving motors for pumping units; the third is to use energy-saving distribution boxes. In recent years, with the development of high-power electronic switching device IGBT, the development of high-cost-effective frequency conversion power supply for pumping unit motors will become the most promising energy-saving product for oilfields. Frequency conversion control technology has been widely used in crude oil gathering and transportation systems, water supply systems, and oil drilling rigs in major oil fields at home and abroad. However, so far, this technology...
