Description

technical field [0001] The invention relates to a motor protection monitoring management device and a management method thereof, in particular to a protection monitoring management device and a management method that can be applied to oil field submersible oil pumps or other motors. Background technique [0002] The submersible pump monitoring device is used to monitor and protect the submersible pump. The submersible pump monitoring device is usually composed of a motor protector and a current recorder; , overvoltage, undervoltage, voltage imbalance and other protection functions; the current recorder draws the real-time current value of the motor on the punching paper, and the punching paper is replaced regularly by relevant personnel; [0003] The original submersible electric pump monitoring device is widely used in oil fields, which improves the reliability of the equipment to a certain extent, but the original submersible electric pump monitoring device still has the f...

AI Technical Summary

Problems solved by technology

[0004] 1. The motor protector used does not have a communication function. In order to realize the digital oil field, it is necessary to add a new set of current transformer and RTU device. The current transformer collects the current, and the collected value is sent to the RTU unit. The RTU unit passes GPRS or other channels. This method is widely used in oil field reconstruction, but the addition of a current transformer acquisition system increases system investment and is inconvenient for maintenance and construction;

[0005] 2. The current recorder is a punch-card type, the recording cycle end and paper remain unchanged and the current data cannot be used directly by the user. It needs to be re-entered into the computer before it can be used. The overall efficiency is not high and the maintenance is difficult.
