Embodiment

[0018] A data reconstruction method for integrated isolation circuit breaker defect database evaluation, comprising the following steps:

[0019] Step 1, assuming that the defect data sets of circuit breaker, operating mechanism, grounding switch, current transformer and monitoring control device are respectively M={M 1 , M 2 , M 3 , M 4 , M 5}, each device contains different types of faults, which can be expressed as M i ={M i1 , M i2 ,... M in}, after data reconstruction, the defect data set of integrated isolation circuit breaker is M'={M 1 ', M' 2 , M 3 ', M' 4 , M 5 '}. The components of the integrated isolation circuit breaker are compared with the corresponding components of the traditional substation. The comparison results of each component are shown in Table 1.

Abstract

The invention discloses a data reconstruction method for evaluating the defect library of an integrated isolating circuit breaker. The components of the traditional circuit breaker and the integrated isolating circuit breaker are compared, and the same components and different components of the two are obtained through comparative analysis. For the same components, directly write the defect data in the traditional substation into the defect database of the integrated isolating circuit breaker. For different components, analyze the improvement points of these components of the integrated isolating circuit breaker, eliminate the defect data eliminated by the improvement, and convert the rest Defect data is written into the integrated isolating circuit breaker defect library. Considering the overall improvement advantages of the integrated isolating circuit breaker, the obtained defect data is optimized to obtain a defect library of the integrated isolating circuit breaker that is closer to the actual situation. After the data reconstruction of the present invention, the data deviation is small, and the defect library of the obtained integrated isolating circuit breaker is closer to the actual situation, which solves the problem of insufficient data of the integrated isolating circuit breaker.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a data reconstruction method for evaluating defect databases of integrated isolation circuit breakers. Background technique [0002] With the rapid and intelligent development of substations, more and more smart substations have been established and put into operation, and a number of new types of smart substation equipment have also been applied, especially the use of integrated isolation circuit breakers. [0003] At present, the operation time of integrated isolating circuit breakers is short, and there are relatively few data related to its operation. It is difficult to establish a corresponding defect database with complete data, which affects the evaluation of the status of integrated isolating circuit breakers. In traditional substations, circuit breakers, operating mechanisms, grounding switches, current transformers and other equipment have been put into operatio...
