A circuit breaker intelligent control method of based on target line state detection

Abstract

The invention discloses a circuit breaker intelligent regulation and control method based on target line state detection. The method includes S1, establishing a first corresponding relation model among a line diameter, a detection point distance and a temperature change range and storing the first corresponding relation model; S2, establishing a second corresponding relation model among the lengthof the line, the distance of the detection point and the temperature change range, and storing the second corresponding relation model; S3, collecting the diameter and length of the target line, andthe temperature at the first detection point and the second detection point; S4, searching the corresponding first temperature change range and the second temperature change range; S5, regulating andcontrolling the working state of the circuit breaker on the target line. The invention considers and sets a plurality of parameter reference models from the self-state of the line, In order to analyzethe influence of the line state on the overall temperature change of the line, and then through the analysis of the actual temperature on the line to determine the safety of the target line, directlyand quickly regulate and control the working conditions of the line so as to ensure the safety and stability of the line.

Description

technical field [0001] The invention relates to the technical field of circuit breaker control methods, in particular to an intelligent control method for circuit breakers based on target line state detection. Background technique [0002] A circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The division of high and low voltage boundaries is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances. Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, protect power lines and motors, and automatically cut off the circuit when they are severely overloaded, short-circuited, or under-voltage. Its function is equ...
