Description

TECHNICAL FIELD

Traditional sulfur hexafluoride insulation gas can destroy the ozone layer and cause the greenhouse effect, so the development of new environment-friendly insulation gas friendly to the ozone layer has become a hot topic in this research field. New insulation gas generally exists in the form of compounds, and the gas itself and the decomposition gas generated under the action of the electric field of the power equipment may affect the environment and personnel safety, in addition, the economic cost of developing and producing different insulation gases is also different. Therefore, how to comprehensively evaluate the performance of environment-friendly insulation gas in multiple dimensions is an important problem to be solved in electrical engineering.

[0003] In the existing evaluation research of gas, single-dimensional evaluation is generally carried out according to the purpose of the gas, such as whether the insulation performance is excellent, whether the environmental protection is in line with the regulations, whether the toxicity is in line with the regulations, whether the decomposition characteristics meet the expectations, etc. However, in actual use, multiple physical / chemical properties of the gas will play their roles, and directly integrating single-dimensional evaluation information will cause the problem of relatively fragmented evaluation of each index. Moreover, based on different use scenarios, the requirements for different performances are completely different, and the current scheme cannot directly obtain the optimal selection, and the efficiency and accuracy of manual selection are poor. Therefore, how to comprehensively consider the multi-dimensional indexes affecting the performance of insulation gas, and combine the difference in the degree of requirement of each dimensional index in engineering practice to comprehensively evaluate the insulation gas to obtain the optimal selection under different requirements is a technical problem to be solved at present.

[0047] Collect data of the gas to be evaluated based on the comprehensive evaluation index, and obtain the initial value of the evaluation index;

[0048] Normalize and dimensionless the initial value of each dimension evaluation index in the index system, respectively, to obtain the evaluation index value I=(I1, I2,..., I m ), I i (i=1, 2,..., m) is the normalized and dimensionless value of each dimension evaluation index.

[0049] In this embodiment, as shown in Figure 2As shown, the established comprehensive evaluation index system mainly includes four main dimensions of insulation, safety, environmental friendliness and economy, and contains eight indexes of breakdown field strength I1, arc extinguishing ability I2, inhalation toxicity I3, carcinogenic toxicity I4, greenhouse effect I5, environmental toxicity I6, manufacturing cost I7, and maintenance cost I8 under each corresponding dimension.

[0050] The normalization and dimensionless algorithm of the index value is:

[0051]

[0052] In the formula, I represents the normalized and dimensionless value of the index, I 实际 represents the actual value of the index, I 实际max represents the maximum value in the actual value of the index.

[0053] The unit nonlinear base function is established, the evaluation index value is substituted into the unit nonlinear base function, and the influence degree of each dimension evaluation index on the comprehensive performance is obtained.
