Breaker risk evaluation system and risk evaluation method thereof

Abstract

The invention discloses a breaker risk evaluation system and a risk evaluation method thereof. The system comprises data management equipment, diagnosis analysis equipment connected with the data management equipment, and search statistic equipment connected with the diagnosis analysis equipment, wherein the data management equipment is used for acquiring equipment machine-account data, technical parameter data, state evaluation conclusion data, environment and safety factor data and accumulated failure occurrence statistic data from a data center; the diagnosis analysis equipment is used for diagnosing and analyzing accessed data according to an optimal risk evaluation model and outputting a risk evaluation result; and the search statistic equipment is used for counting and searching the accessed risk evaluation result, outputting an evaluation conclusion report, and carrying out equipment pre-warning by combining state pre-warning. By adopting the breaker risk evaluation system and the risk evaluation method, information related to breaker equipment can be uniformly maintained and managed with environmental and historical failure data, accident occurrence is reduced, the management level of equipment is improved, and safe and stable operation of a power grid is guaranteed.

Description

technical field [0001] The invention relates to the maintenance technology of circuit breaker equipment, in particular to a circuit breaker risk assessment system and a risk assessment method thereof. Background technique [0002] The SF6 circuit breaker can not only cut off and connect high-voltage lines and various no-load and load currents when the system is running normally, but also cut off various overloads automatically, quickly and reliably through the function of the relay protection device when the system fails. Load current and short-circuit current are the key equipment to ensure the stable operation of the power grid to prevent the occurrence and expansion of the scope of accidents. Therefore, it is especially important to reduce the number of failures of SF6 circuit breakers and ensure their normal operation. The risk assessment is an important means to quickly identify the potential risks of equipment, avoid and reduce the accident discovery of SF6 circuit br...

Problems solved by technology

Among them, knowledge-based analysis and qualitative analysis mainly rely on the experience and intuition of professional consultants or the standards and practices of the industry to qualitatively grade the size or level of various risk-related elements (asset value, threat, vulnerability, etc.) The experience and ability of personnel put forward higher requirements, especially the hidden dangers of equipment failures, which are affected by environmental, human and other factors, resulting in untimely statistical analysis and inaccurate conclusions during risk analysis, thus affecting the safety of the power grid. Operation constitutes a certain degree of influence
