Reliability Study of Low Voltage Switchgear Based on Trapezoidal Fuzzy Number
Junlan Nie · Low Voltage Apparatus · 2011
In view of the inaccurate factors for the probability of equipment failure,the reliability analysis of low voltage switchgear system was analyzed by fuzzy fault tree theory.According to the analysis of water pump circuit system of low voltage switchgear using trapezoidal fuzzy number,the fuzzy probability of return route failure and the fuzzy importance degree of bottom event were obtained.Combing with the fuzziness of probability and the project error,it has wide spread application prospect in the reliability project.
