Embodiment Construction
[0024] See figure 1 , figure 2 , Table 1, a high-voltage circuit breaker short-term reliability evaluation method, the present invention is characterized in that its method steps are:
[0025] (1) Establish a circuit breaker fault tree
[0026] The circuit breaker can be divided into three parts: the circuit breaker body, the energy storage mechanism and the transmission mechanism; according to the in-depth analysis of the failure modes of each component of the circuit breaker, according to the structural characteristics of the circuit breaker, combined with the previous collection and arrangement of circuit breaker fault information, The circuit breaker fault T is divided into three categories: body fault A1, energy storage mechanism fault A2, and transmission mechanism fault A3; where T is the top event of the fault tree, Aj where j=1,2,9, Ek where k= 4.1, 4.2,...,6.5 are the middle events of the fault tree, and Xi where i=1.1,1.2,...,9.7 is the bottom event of the fault ...
