Introduction

Low-voltage electrical appliances are produced in large quantities and used extensively, including power distribution appliances, control appliances, and terminal appliances. Their reliability has a wide-ranging impact on the application of low-voltage electrical appliances. It is used in various fields such as machinery, electricity, and electronics, involving multiple aspects such as power control and distribution. GB/T 22200 "Reliability of Low-Voltage Electrical Appliances" It is an important series of standards that guide the reliability verification of low-voltage electrical products in my country, and is planned to consist of 7 parts. ---Part 1.General Rules. The purpose is to specify the general requirements for the reliability of low-voltage electrical appliances. ---Part 2.Reliability Test Methods for Molded Case Circuit Breakers. The purpose is to specify the reliability requirements for molded case circuit breakers. Requirements and related requirements such as test methods. ---Part 3.Reliability Test Methods for Overload Relays. The purpose is to specify the reliability requirements and test methods for overload relays. And other related requirements. ---Part 4.Reliability Test Methods for Overcurrent Protection Circuit Breakers for Household and Similar Applications. The purpose is to specify the reliability test methods for overcurrent protection circuit breakers used in household and similar applications. The reliability requirements and test methods for overcurrent protection circuit breakers used in similar locations are also relevant requirements. ---Part 5.Residual Current Operated Circuit Breakers for Household and Similar Use - Test Methods for Reliability. The purpose is to specify the reliability testing methods for household and similar applications. Reliability requirements and testing methods for similar applications. ---Part 6.Reliability Test Methods for Contactor Relays. The purpose is to specify the reliability requirements for contactor relays and... Requirements related to test methods, etc. ---Part 7.Contactor Reliability Test Methods. The purpose is to specify the reliability requirements and test methods for contactors. Require. The purpose of this document is to harmonize as much as possible all rules and requirements applicable to the reliability of low-voltage electrical appliances, so as to provide a basis for the corresponding low-voltage electrical products. Reliability requirements and tests should be standardized. This document contains all the content considered essential requirements in various product reliability standards, as well as content with broad significance and application. Specific items, such as reliability indicators and reliability level classification; reliability test plans and test procedures, etc. For each type of low-voltage electrical product, determining all its requirements and tests requires only two main standards. a) This document is referred to as "Part 1" or "GB/T 22200.1" in various standards for the reliability of low-voltage electrical appliances; b) Reliability standards for the relevant products, referred to below as “relevant product reliability standards” or “reliability standards for this series of products”. General rules applicable to reliability standards for a specific product shall be clearly stated in the product reliability standard and referenced. Only when there are sufficient technical reasons can a specific product reliability standard differ from the general rule. Note. The “product reliability standards” mentioned in this document refer to the “GB/T 22200 series product standards”. Low-voltage electrical equipment reliability - Part 1.General principles
