摘要：
In view of the inaccurate factors for the probability of equipment failure, the reliability analysis of the low-voltage switchgear system is analyzed by fuzzy fault tree theory. According to the analysis of water pump circuit system of low-voltage switchgear using trapezoidal fuzzy number, we can obtain the fuzzy probability of return route failure and the fuzzy importance degree of bottom event. Combined with the fuzziness of probability and the project error, has widespread application prospect in the reliability project.
