Introduction
With the improvement of equipment manufacturing level, especially the development of chip technology, local protection devices will be close to the local arrangement or
Integration with primary equipment to improve protection performance: The content and depth of existing technical standards for protection devices based on indoor installation are no longer applicable:
GB/T 40096 is intended to consist of the following parts:
--- Part 1: General technical conditions: The purpose is to standardize the technical requirements, test methods and inspection specifications of local relay protection devices:
and general requirements for marking, packaging, transportation, storage, etc:
--- Part 2: Connectors and prefabricated cables: The purpose is to standardize the product requirements of connectors and prefabricated cables:
--- Part 3: Local operation box: The purpose is to standardize the product requirements of local operation box:
--- Part 4: Intelligent management unit: The purpose is to standardize the product requirements of intelligent management units:
--- Part 5: Line protection: The purpose is to specify the functional specifications and technical requirements of line protection:
--- Part 6: Busbar protection: The purpose is to specify the functional specifications and technical requirements of busbar protection:
--- Part 7: Transformer protection: The purpose is to standardize the functional specifications and technical requirements of transformer protection:
Technical specification for local relay protection device
Part 7: Transformer protection
