Maintenance system of power equipment based on risk assessment

Abstract

The present invention discloses a maintenance system of a piece of power equipment based on risk assessment, comprising: that a data acquisition unit monitors original data of the power equipment and the acquired original data is saved to a database server; a data processing unit processes the acquired original data to generate a processing result; an application service unit allows a user to access the original data and interactively operates the processing result; and the user determines whether the power equipment needs to be maintained based on the processing result and the original data. Using the system in the invention, blindness of the equipment maintenance can be dramatically reduced and insufficient or over maintenance can be avoided, and then a principle that what needs to be maintained should be maintained and what should be maintained needs good maintenance of the equipment can be realized, while a lot of maintenance cost can be saved, safe and stable operation of the equipment is guaranteed and a managing level of the equipment is greatly enhanced.

Description

technical field [0001] The invention belongs to the field of equipment condition maintenance in electric power enterprises, and in particular relates to a risk assessment-based power equipment maintenance system. Background technique [0002] The development of electrical equipment maintenance system can be roughly divided into three stages: accident maintenance (BM, Break Maintenance), planned maintenance (SM, Schedule Maintenance), and condition maintenance (CBM, Condition-Based Maintenance). [0003] Break Maintenance (BM, Break Maintenance), also known as breakdown maintenance, is the earliest maintenance method. This maintenance method takes the functional failure of the equipment as the criterion, and only performs maintenance when the equipment fails and cannot continue to operate. Obviously, this kind of emergency maintenance needs to pay a lot of safety, economic cost and maintenance cost, which not only seriously threatens the equipment or personal safety, but also...

Problems solved by technology

Due to the lack of accurate data on risk assessment models and quantitative risk assessment indicators, the risk value depends on the personal experience of the evaluator, and the risk assessment value obtained, because personal subjective factors account for a large proportion, it is easy to cause risk assessment to fail due to personal experience , resulting in under-maintenance or over-maintenance
