Prediction method of electric energy meter replacement time based on salt spray aging and condition monitoring

Abstract

The invention discloses a method for predicting the replacement time of an electric energy meter based on salt spray aging and state monitoring, and relates to the field of electric energy meter life prediction. The southern coast of my country has a hot and humid salt fog climate, and simple replacement of electric energy meters causes economic and safety problems. Before the smart electric energy meters are put into use, the present invention extracts a certain number of intelligent electric energy meters, carries out the salt spray aging test and obtains the life function, and then deduces the service life of the intelligent electric energy meters in the actual salt spray environment. After the intelligent electric energy meters are put into use , combined with the measurement error of the smart energy meter obtained in the monitoring system, the life function is corrected to obtain the replacement time of the smart energy meter in the actual salt spray environment. This technical solution considers the influence of the salt fog climate on the smart electric energy meter, and obtains the life function in the salt fog environment; and according to the measurement error in the use process, corrects the life function, and obtains a more economical and reasonable replacement cycle of the intelligent electric energy meter. Improve the efficiency and safety of smart energy meters.

Description

technical field [0001] The invention relates to the field of life prediction of electric energy meters, in particular to a method for predicting replacement time of electric energy meters based on salt spray aging and state monitoring. Background technique [0002] At present, with the large-scale application of smart energy meters in my country, the replacement strategy of smart energy meters generally adopts the method of replacement after failure or unified rotation when it expires. The replacement method after failure lacks predictability, and the replacement is relatively passive, which is easy to cause abnormal electricity measurement. , And lead to economic disputes, and the unified rotation makes a large number of electric energy meters with good operating performance scrapped early, resulting in a serious waste of manpower, material resources and other resources. In addition, in the hot and humid salt fog climate in the southern coast of my country, smart energy mete...

[0002] At present, with the large-scale application of smart energy meters in my country, the replacement strategy of smart energy meters generally adopts the method of replacement after failure or unified rotation when it expires. The replacement method after failure lacks predictability, and the replacement is relatively passive, which is easy to cause abnormal electricity measurement. , and caused economic disputes, and the unified rotation caused a large number of electric energy meters with good performance to be scrapped early, resulting in a serious waste of manpower, material resources and other resources

In addition, in the humid and hot salt fog climate along the southern coast of my country, smart energy meters are more prone to performance degradation and failure, and simple replacement methods are more likely to cause economic and safety problems in the operation of smart energy meters

[0003] Because, in view of the lack of predictability and economy in the replacement method of the smart electric energy meter in the coastal salt fog climate, it is necessary to improve and optimize the replacement method of the smart electric energy meter to improve the efficiency and safety of the smart electric energy meter
