【 摘 要 】

This article classifies and analyzes the failures of low-pressure metering boxes to ensure accurate and reliable energy metering. Component Critical Assessment (CCA) method was used to evaluate various components of the metering box system. Failure Mode and Effect Analysis (FMEA) method was used for risk assessment of the low pressure metering box. Establish a database of low-pressure metering faults, responsible for the storage, management, and maintenance of fault data. A fault crossover analysis model was established to analyze the strength of the correlation between the impact factors of the low pressure metering box. Optimize the transportation, storage and use of low-pressure metering boxes to reduce the failure of metering boxes.
