Study on the Relationship Between the Length of Distribution Circuits and the Selection of Circuit-Breakers
This paper studies the relationship between the length of distribution circuits and the selection of the circuit-breakers.By analyzing the single-phase grounding faults in distribution circuits using double splicing cables in practical projects,this paper explores the possibility of cable distribution distance,short-circuit current,and circuit breaker selection.By the analysis of the different situations of short-circuit current in distribution circuits,referring to product samples and national standards,suggestions for selecting distribution cable circuit breakers are provided,which can provide theoretical basis for the optimal design.
