Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

1 Scope

This standard specifies the terms and definitions, product models and basic parameters of industrial battery charging rectifier equipment (hereinafter referred to as charging rectifier equipment). Data, technical requirements, testing, marking, packaging, transportation and storage.

This standard applies to the DC output voltage used in industrial sites not exceeding 1000V, and the DC power of a single power unit is not less than 10kW, a charging rectifier device composed of single or multiple power units, also suitable for charging rectifiers installed in other devices as accessories equipment. Electric power engineering, post and telecommunications battery charging, floating charge rectifier equipment can also be used as reference.

Note: The charging and rectifying equipment is used to charge or discharge rechargeable batteries, and provide battery charging or discharging for battery formation and similar equipment. Cable connection or permanent connection.

This standard does not apply to battery chargers for fire alarm signal fire protection systems, household battery chargers, battery chargers for automobile starting, The battery charger that drives the centrifugal ignition pump internal combustion engine and the equipment that uses the battery charger as other system applications. In this standard Fast charging is also not suitable for charging lead-acid lean-liquid batteries.
