A circuit breaker intelligent control system based on load current detection

Abstract

The invention discloses a circuit breaker intelligent control system based on load current detection: the information storage module is used to store the average load current I of the target line at a specified time m days before the current date 0 ; The information collection module is used to collect the actual average load current I of the target line at the specified time on the current date 1 The node separation module is used to obtain the actual load currents at the m collection nodes respectively; the circuit breaker regulation module is used to regulate the start-stop state of the circuit breaker on the target line. The present invention is provided with a plurality of load current collection nodes, and collects and analyzes the actual load currents at different positions on the target line through sub-nodes, which can ensure timely and accurate collection of load current changes at different positions, so as to more quickly Find the area with excessive load current on the target line, so as to timely and quickly adjust the working state of the circuit breaker on this line to ensure the stability and safety of the target line.

Description

technical field [0001] The invention relates to the technical field of circuit breaker control, in particular to an intelligent control system for circuit breakers based on load current detection. Background technique [0002] The power supply department can only give a limited load value for the electricity consumption of each power consumption unit under its jurisdiction, which is a value obtained by evaluating the peak power consumption of each power consumption unit and the possible power supply of the power supply department. However, the power consumption of a large number of power consumers under the jurisdiction of a certain power supply department varies greatly in different time periods of the day, and the load current generated by the circuit also varies greatly. The peak power consumption may reach hundreds of amperes, but it may only be Ten amps. During the peak of power consumption, if the load current is too large, the circuit breaker can play a protective ro...

AI Technical Summary

Problems solved by technology

During the peak of power consumption, if the load current is too large, the circuit breaker can play a protective role, but in the valley of power consumption, because the load current is small and the gear is relatively large, sometimes the occurrence of the fault cannot be judged

All of the above are frequent and very dangerous situations in the use of circuit breakers. Therefore, in order to use circuit breakers and electricity more safely, how to avoid these problems as much as possible has become the focus of current circuit breaker system technology research.
