A transmission line iron tower safety evaluation system and its evaluation method

Abstract

The invention relates to an evaluating system for electric transmission line iron tower safety and evaluating method thereof. The evaluating system comprises a data collecting module, a controlling module and an output module connected in sequence; the controlling module comprises an iron tower safe state grading module, a judging module and a comparing module. The evaluating system collects information of iron tower state through the data collecting module, conducts grading and ranking to the iron tower state through the controlling module, and finally transmits all evaluation information to the output module. According to the technical scheme, potential safety risks of an electric transmission line iron tower can be found timely, so that the iron tower safety is mastered accurately, therefore technical support is provided for operation and maintenance of the iron tower, and safe and reliable operation of electric transmission line are guaranteed.

Description

Technical field: [0001] The invention relates to an evaluation system and an evaluation method thereof, and more particularly to a power transmission line iron tower safety evaluation system and an evaluation method thereof. Background technique: [0002] At present, my country's safety assessment of transmission line towers is mainly based on "Evaluation Standards for Power Transmission and Transformation Equipment" (Trial) (2006), "Guidelines for State Evaluation of Power Transmission and Transformation Equipment" (Q / GDW173-2008) and "Transmission Substation Equipment Condition Evaluation Standard" (Q / CSG 10010-2004) three standards. First of all, the evaluation of the three standards only stays at the evaluation level of the safety state, and does not go deep into the safety performance level of the tower structure, which belongs to a relatively broad and extensive evaluation system. Secondly, the evaluation of the three standards is carried out for the iron towers of the...

AI Technical Summary

Problems solved by technology

First of all, the evaluation of the three standards only stays at the evaluation level of the safety state, and does not go deep into the safety performance level of the tower structure, which belongs to a relatively broad and extensive evaluation system

Secondly, the evaluation of the three standards is carried out for the iron towers of the entire line. The iron towers of the line usually have multiple bases. The illusion that the overall state is poor, resulting in a partial evaluation conclusion

Thirdly, in terms of evaluation methods, the three standards only apply the evaluation method of the safety state of transmission line towers, and the evaluation method is relatively simple, mainly citing several state quantities that affect the safety state of iron towers, so it should belong to the analysis method of influencing factors. Analytic Hierarchy Process

Finally, in terms of safety performance evaluation, the three standards do not involve

Therefore, the existing transmission line tower safety evaluation system is an extensive evaluation system, which can no longer meet the needs of the existing transmission line safety evaluation work.
