Scope

Scope: This standard specifies the terms and definitions, symbols and abbreviations, interface characteristics, information, usage conditions, structural requirements, performance requirements, functional requirements, and test methods for intelligent low-voltage complete power switchgear and control equipment. This standard applies to intelligent low-voltage complete power switchgear and control equipment with a rated voltage of not more than 1000V AC and frequency of not more than 1000Hz, and a rated voltage of not more than 1500V DC. This standard is applicable to member enterprises of the Wuhan Electrical Industry Association for manufacturing and use. Non-member enterprises may refer to and use it for reference. Main technical content: The "Intelligent Low-Voltage Complete Power Switchgear and Control Equipment" is used as the evaluation and certification basis for "Wuhan Famous Products". The main technical content is briefly described as follows: The distribution cabinets are designed to be safe and reliable, not only meeting the low-voltage distribution needs of various industries in an all-round way, but also perfectly meeting the specific needs of high-safety standard industries such as petroleum and petrochemical, mining, and nuclear energy; for the requirements of the petroleum and petrochemical industry for power supply safety and continuity, it provides intelligent motor control and distribution systems. The project requires raising the insulation voltage level to Ui=1000V, increasing the use requirements of rated operating voltage Ue=400V/690V, and enhancing internal arc protection; for the requirements of mines and metallurgy for environmental tolerance and power supply safety, special anti-corrosion treatment is carried out on conductive components, and the IP protection level of the cabinets is improved; for the requirements of nuclear power stations for power supply reliability and earthquake resistance, the distribution cabinets are designed a
