Study of Reliability of Substation for Coal Mine Supervision System

The sub-station has direct impact on the reliability of coal mine safety monitoring system reliability. The mine sub-station reliability of expected value and accelerated life test of the reliability value is given by setting the number of tests Censored Bayesian methods and Fixed Number Truncated of constant-stress accelerated methods on sub-station reliability research, and a sub-station with the voltage changes in the average life expectancy curves is simulationed. Through research we can see that the two methods to verify the reliability of the results of similar, and thus proved the scientific nature of the two methods.
