Foreword

According to the “National Energy Administration’s Circular on Issuing the.2016 Energy Sector Standard System (Revision) Plan Knowledge” (Guoneng Technology (2016) No. 238), the specification preparation team has conducted extensive investigations and studies, earnestly Based on practical experience, and on the basis of extensive solicitation of opinions, this specification will be revised. The main technical content of this specification is. basic regulations, high-voltage electrical equipment selection, high-voltage electrical equipment Layout. The main technical content of this specification revision is. --Added the terms "dismantling transportation power transformer" and "handover current". --Added solid insulated tubular bus bars, dismantling and transportation power transformers, auxiliary power transformers, and Sub-type voltage transformers, electronic current transformers, insulators, bushings, line wave traps, gas-filled gold It belongs to enclosed switchgear, high-voltage fuses, etc. - Revised the scope of application of the code, from "3kV~500kV" to "3kV~750kV". -Revised the altitude correction formula for the external insulation of electrical equipment, the classification of pollution levels and the creepage distance Requirements. This specification is managed by the National Energy Administration, proposed by the General Institute of Hydropower and Water Conservancy Planning and Design, and is responsible for daily management. The technical committee for standardization of hydropower and electrical design in the energy industry is responsible for the interpretation of specific technical content.
