Scope

Scope: This standard specifies the usage conditions, technical requirements, design, manufacturing, testing, transportation, storage, installation, operation, and maintenance principles for 12-kV intelligent distribution pole-mounted switches (hereinafter referred to as "intelligent pole-mounted switches"). This standard applies to intelligent pole-mounted switch equipment used in 12-kV, three-phase power systems with a frequency of 50 Hz. Main technical content: 1) Scope: This standard specifies the usage conditions, technical requirements, design, manufacturing, testing, transportation, storage, installation, operation, and maintenance principles for 12-kV intelligent distribution pole-mounted switches (hereinafter referred to as "intelligent pole-mounted switches"). This standard applies to intelligent pole-mounted switch equipment used in 12-kV, three-phase power systems with a frequency of 50 Hz. The standard stipulates the usage conditions, functional requirements, performance indicators, test items, and application methods for 12-kV intelligent distribution pole-mounted switches. It also proactively outlines the intelligent requirements for pole-mounted switches, overall accuracy requirements, and integrated testing requirements for the entire device. 2) Usage conditions: These include ambient environmental conditions, altitude, contamination resistance, wind speed, ice accretion, and vibration/impact or swing. Intelligent pole-mounted switches operate in the same environments as conventional outdoor switch equipment. According to DL/T 593-2016, the ambient air temperature around outdoor switch and control equipment should not exceed 40°C, and the average temperature measured over 24 hours should not exceed 35°C. Considering the increasingly high summer temperatures in recent years (for example, in July 2018, many regions in the middle and lower reaches of the Yangtze River exceeded 40°C, with some areas experiencing body temperature sensations of up
