Research On The Influence Of High Temperature And High Humidity On Electronic Energy Meter

With the continuous development of smart grid,the application of electronic energy meters is more and more widely.The failure of the energy meter affects the measurement of electricity consumption by users.Improving the reliability of the operation of electronic energy meters is of great significance for better improving the quality and efficiency of the operation and maintenance of energy metering and improving the satisfaction of users with power supply enterprises.This paper takes the electronic energy meter in the high temperature and high humidity area as the object,analyzes and deals with the climatic conditions of the high temperature and high humidity area represented by the Guangdong area based on temperature and humidity,and further clarifies the typical operating environment of the electronic energy meter in the humid and hot area Conditions and curve-fit the correlation of temperature and humidity to provide a basis for formulating a test environment model for related humid and hot climate conditions.Based on the mechanism of the influence of temperature and humidity stress on electronic products,the fundamental reason for the failure caused by high temperature and humidity is that the physical and chemical reasons alternate or simultaneously act.Combined with the influence mechanism of temperature and humidity stress on electronic products,the effect of high temperature and humidity is accelerated the factors of the deterioration or failure of the electronic energy meter provide a basis for the subsequent damp heat test.According to the influence of temperature stress and humidity stress on electronic products,according to the relevant test standards,carry out the strict alternating heat and humidity test on the electronic energy meter,and set and adjust the test parameters such as temperature,humidity interval,parameters,cycle,etc.The constant damp heat test is used to evaluate the life characteristics of the electronic energy meter under high temperature and high humidity conditions,as a comparison of the above-mentioned stringent alternating damp heat test.There are two ways to strengthen the influence of high temperature and high humidity stress,and accelerate the failure problems that are nearer to occur under the southern China climate conditions.Under the test conditions of constant high humidity and high heat,the electronic energy meter has better humidity resistance.However,in the alternating humidity and heat test,failure problems such as liquid crystal failure and error tolerance are exposed,which is more likely to cause failure of the electronic energy meter.Based on the collected measurement data,the cause of the faults in the test process is analyzed.By establishing a fuzzy fault comprehensive evaluation model,the fault status of the electronic energy meter is analyzed,and the fault status of the electronic energy meter is comprehensively evaluated under high temperature and high humidity.And use the measurement data in the temperature and humidity test to analyze the feasibility of the fuzzy evaluation model.Finally,based on the above-mentioned tests and analysis,suggestions are made for improving the resistance to humidity and heat of electronic energy meter products.Improving the reliability and quality of the operation of electronic energy meters will effectively save the test time of electronic energy meter components and on-site measurement and maintenance time,reduce energy meter failures and economic losses,and improve the working capacity and efficiency of measurement and maintenance personnel,In high temperature and high humidity areas or other specific will have the promotion value.
