A typical environment detection method for low-pressure metering box

Abstract

The invention discloses a typical environment monitoring method for low-pressure metering boxes. The typical environment monitoring method comprises on-site operation detection and outdoor stewing detection; during the test, various low-pressure metering boxes are selected; during the on-site operation detection, environmental data, environmental data in box bodies and appearance and temperature rise data of the box bodies are monitored, so that a multi-index influence rule and an index change tendency under an extreme environmental condition are obtained; during the outdoor stewing detection, the low-pressure metering boxes are exposed in a typical environment for a period of time to perform material testing on the low-pressure metering boxes before and after the exposure, and corrosion conditions of metal parts in the low-pressure metering boxes are verified, so that performance change estimation is performed on materials of the low-pressure metering boxes. The typical environment monitoring method for the low-pressure metering boxes can fully simulate a change process of the low-pressure metering boxes under a natural condition; by means of long-time on-site real load operation and outdoor stewing test, a mass of data are accumulated, so that the research on a correlation rule among a plurality of aging factors and the research on a comprehensive action effect of all environmental factors on the low-pressure metering boxes can be developed favorably.

Description

Technical field [0001] The invention relates to the technical field of testing, in particular to a method for detecting a typical environment of a low-pressure metering box. Background technique [0002] Metering equipment is the basis for trade settlement of various interconnected power grids. Its reliability not only affects the safety, stability, and economic operation of smart grids, but also affects the reliability and safety of electricity consumption by thousands of households. However, with the promotion of the global energy Internet, the installation coverage of metering equipment is becoming wider, the geographical environment of its location is becoming more and more complex, and the climate experienced is becoming more and more diversified, especially under severe weather conditions in certain regions. , The metering equipment often fails. The low-voltage metering box, as the protective shell of smart energy meters, collection terminals, isolating switches and circui...

Problems solved by technology

Although the accelerated aging test has the characteristics of shortening the test time, saving samples and test costs, and quickly obtaining test results, it also has obvious deficiencies. The accelerated aging test is carried out under the condition that a single natural aging factor is relatively stable. There are considerable deficiencies in the research on the interrelated and comprehensive effects of multiple aging factors, and the change process under natural conditions cannot be fully simulated; in addition, as the most realistic and effective method for evaluating the aging resistance of plastic materials, the domestic natural atmosphere of materials There are very few studies on exposure aging, and there is no relevant research data. Therefore, most manufacturers are not very clear about the reasons for material aging, and cannot propose effective measures to improve and enhance product quality.

Therefore, it is impossible to accurately evaluate the product quality and performance characteristics of the low-pressure metering box in various extreme natural environments
