Scope

Scope: This standard specifies the terms and definitions, usage conditions, model naming, rated values, design and structure, steel structure construction and acceptance, type testing, factory inspection, marking, packaging, transportation, storage, installation, operation, maintenance, and end-of-life procedures for 110kV prefabricated substations. This standard applies to 110kV prefabricated substations with a rated frequency of 50Hz, a rated voltage of 110kV on the high-voltage side, and a rated voltage of 10kV/35kV/380V on the low-voltage side. These substations are typically installed in publicly accessible locations, and personal safety must be ensured under the specified usage conditions. The substations described in this standard are connected via cables and can be operated either from the inside (accessible type) or from the outside (non-accessible type). Main technical content: 1. Rated voltage: For high-voltage switchgear and control equipment, refer to GB/T 11022-2011. For low-voltage switchgear and control equipment, refer to GB/T 14048.1-2012 and GB 7251.1-2013. 2. Rated insulation level: For high-voltage switchgear and control equipment, refer to GB/T 11022-2011; for low-voltage switchgear and control equipment, refer to GB/T 14048.1-2012 and GB 7251.1-2013. The rated insulation level of high-voltage switchgear and control equipment shall comply with the provisions of GB/T 11022-2011, Section 4.3. For low-voltage switchgear and control equipment, the rated lightning impulse withstand voltage shall be at least the value specified in Table F.1 of Annex F of GB/T 16935.1-2008 for Class IV overvoltage. The insulation level of transformers shall comply with the provisions of GB/T 1094.3-2017, Chapter 5. The insulation of auxiliary and control circuits shall comply with the provisions of GB/T 11022-2011, Section 7.3.4. 3. Rated frequency and number of phases: The rated frequency is 50Hz, and the rated number of phases is three. 4. Rated current and temper
