Abstract

Abstract: The article presents an algorithm for estimating reliability parameters - probability of failure-free operation time and failure rate of low-voltage switching devices based on statistical data on failures of circuit breakers installed in control and protection circuits of such consumers as compressors, pumps and fans in industrial enterprises. The theoretical and statistical functions of the probability of the failure-free operation time of automatic circuit breakers depending on the service life and the number of operation cycles have been investigated and a hypothesis has been put forward and confirmed on the normal distribution law of the random variable (probability of failure-free operation o automatic circuit breakers) using the "agreement criteria" - the Kolmogorov test and Pearson's criterion.
