Scope

This standard specifies the general requirements for secluded pole synchronous motors, and specifies the special requirements for air-cooled, hydrogen-cooled or liquid-cooled and gas turbine-driven synchronous motors. This standard also specifies matters needing attention for hydrogen-cooled generators, including rotating exciters driven by synchronous generators, auxiliary equipment required for generator operation, and areas in the plant where hydrogen gas may accumulate. This standard applies to three-phase secluded pole synchronous generators with a capacity greater than 10 MVA (or MW), and it is a supplement to GB 755. All matters not specified in this standard shall comply with the provisions of GB 755. This standard does not include inverter continuous power supply motors and imported generators. This standard is an important basis for users and manufacturers to sign technical agreements. If there are special requirements for specific products, they can be negotiated separately by both parties.
