25 MW box-type light generator for offshore platform

Abstract

The invention discloses a 25 MW box-type light generator for an offshore platform. The generator includes a stator with a ventilation structure, a rotor with an inner air-cooled structure, a double-pipe cooler, anti-tilt anti-swing structures and a synchronous three-machine brushless excitation system. The stator and the rotor form a generator body, the double-pipe cooler is mounted above the generator body, the anti-tilt anti-swing structures are mounted at the two ends of the generator body, and a coating primer for all components is inorganic zinc-rich primer. Through the structure, a seawater medium can be utilized to fully cool a motor, the anti-tilt anti-swing requirements of the motor at sea can also be met, the resistance of the motor to corrosive environments such as salt mist, molds and moisture on the sea is improved, and it is ensured that the generator runs normally on the offshore platform.

Description

technical field [0001] The invention relates to the field of generators, in particular to a 25MW box-type light generator for offshore platforms. Background technique [0002] After years of development, traditional coal, oil and other resources have been gradually replaced by new energy due to their increasingly depleted reserves and relatively serious pollution. With the saturation and limitations of land development, various projects have begun to target the development of offshore and ocean areas based on my country's ultra-long coastline resources. Coupled with the convenience of seawater resources on the ocean, offshore static platforms and offshore platforms are booming. Static platforms, ocean platforms, and nuclear power platforms all need corresponding power and power equipment. As the power source of platform power and power equipment-the development of generators has become an urgent and important task. [0003] Gas turbine generator set is the core equipment of ...

Problems solved by technology

Moreover, the current offshore platform generators cannot meet the requirements of cooling, anti-tilting, anti-corrosion, etc., and cannot guarantee the normal operation of the motor for a long time

Chinese invention patent ZL201320412529.5 discloses a diesel generator set for an offshore platform. The generator is placed in a centralized box, which does not involve structural improvements in cooling, anti-tilt swing, anti-corrosion, etc., and the protection capability is limited.
