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 ...

Abstract

The invention relates to a short-term reliability evaluation method of a high-voltage breaker. The current and recent reliability of the high-voltage breaker is evaluated accurately and quantitatively by a fault tree and fault mode evaluation model via data acquired by all detection means of the current breaker, including routine patrol, special patrol, preventive test data, diagnostic test data, basic standing book information of equipment, equipment defects over the years, fault records and the like. The method for evaluating the reliability of the high-voltage breaker has the advantages of conciseness, intelligibility, accuracy, visuality, quantification and the like.

Description

technical field [0001] The invention belongs to the category of state evaluation of electrical equipment, and is suitable for current and short-term state evaluation of 500kV, 220kV and 110kV high-voltage circuit breakers. Background technique [0002] Modern grid electrical equipment has greater complexity and stronger system, so better ideas are needed to realize the modern management of electrical equipment. Especially for domestic power grid enterprises, the power grid is developing rapidly, and it is necessary to pursue an efficient equipment management model to ensure the safety of power grid production, and to solve the increasingly prominent contradictions between excessive human intervention and equipment maintenance tasks and personnel in the equipment management process . Therefore, it is necessary to establish a repair and maintenance strategy for electrical equipment based on equipment status and reliability, clarify the weak points of electrical equipment, gui...
