GB/T 37549-2019 Technical code for relaying protection of generator-transformer unit in large capacity nuclear power plant
Basic Information
Scope
This standard specifies the basic technical requirements, test methods, inspection rules, and requirements for marking, packaging, transportation, and storage of relay protection devices for nuclear power generator transformer units with a single-machine capacity of 600 MW or more (hereinafter referred to as protection devices).
This standard applies to the protection devices of generator transformer units (hereinafter referred to as generator-transformer units) used in large-scale nuclear power plants, and serves as the basis for the design, manufacture, testing, and operation of such devices. Units with a single-machine capacity of less than 600 MW may refer to this standard for implementation.
This standard also applies to the following protection devices in large-scale nuclear power plants:
——Generator protection devices;
——Main transformer protection devices;
——High-voltage auxiliary transformer protection devices;
——Excitation transformer protection devices.
