Talking about the Design Principle of Submersible Electric Pump Protector
Design a special submersible electric pump protector that meets the characteristics of submersible electric pump. The submersible electric pump protector has protection functions such as overload, phase failure, unbalance, over voltage, under voltage and voltage imbalance. Given the design principle of such products, the difference between the product and the conventional motor protector and its hardware and software design principles are introduced.
The submersible electric pump is a medium-pressure mechanical oil recovery equipment used in oil fields. With the improvement of the automation level of oilfield development, the original submersible electric pump fixed-frequency control cabinet has imperfect leakage function, inconvenient data analysis, no waveform recording, no communication function, etc., and the main reason for these shortcomings is non-specifically targeted to submersible oil. The protector of the electric pump does not support the above functions.
At present, there are few domestic manufacturers researching and developing submersible electric pumps, and the scale is small, and the products have not formed serialization and scale. In order to enhance the competitiveness of domestic submersible electric pump protectors and make up for the shortage of old-fashioned protectors, it is necessary to develop a targeted submersible electric pump protector.

2 submersible electric pump protector features
3 submersible electric pump protector product composition
The submersible electric pump protector consists of a protector body, a human-machine interaction module, and a switching power supply, as shown in FIG. The main body of the protector completes the functions of parameter collection, protection and communication; the human-computer interaction module realizes real-time parameter display, parameter setting, real-time curve display, historical curve display, historical data query, fault query and other functions; the switching power supply will be AC/DC 220V (or Other grades) The voltage is converted to a low voltage for use by the main body and the human-machine interaction module.
