A central air-conditioning system for regulating the temperature of wind power generators

Abstract

The invention discloses a central air conditioning system for adjusting temperatures of a wind turbine generator system. The wind turbine generator system comprises a cabin cover and a plurality of temperature compensation components arranged in the cabin cover; the central air conditioning system comprises a central air conditioner which is installed at the top in the cabin cover and located above the temperature compensation components, the central air conditioner is connected with a plurality of air outlet channels which are provided with air outlets, and the air outlets are distributed and distributed at the bottom and on the side wall of the cabin cover and align to the temperature compensation components to form inner air channels; when the central air conditioner is in a heating mode, hot air sent by the air outlets are upwards blown out from the lower portion of the cabin cover, air current covers the temperature compensation components and forms circulation in the cabin cover; and when the central air conditioner is in a cooling mode, the air outlets aligning to self-heating components blow out cold air, and air current only covers the self-heating components for local cooling. According to the central air conditioning system for adjusting the temperatures of the wind turbine generator system, operation modes of heating and refrigeration are automatically selected according to temperatures of the components, and fast and energy-saving temperature controlling is achieved.

Description

technical field [0001] The invention relates to a central air-conditioning system, in particular to a central air-conditioning system for regulating the temperature of a wind power generating set. The utility model belongs to the technical application field of wind power generating sets. Background technique [0002] A wind turbine is a device that converts wind energy into electrical energy. When wind energy passes through the blades of the wind rotor, the blades are driven to rotate, and the rotation of the blades drives the hub and the main shaft to rotate. The main shaft rotates to input power into the gearbox. It is transmitted to the generator, which drives the generator rotor to rotate, thereby generating electric energy. [0003] The gearbox needs to be lubricated and cooled to operate efficiently. There is a large amount of lubricating grease in the gearbox. When the gearbox is running normally, the oil temperature in the gearbox will increase. At this time, the he...

Problems solved by technology

The lubrication method mostly adopts centralized lubrication, and each lubrication point uses lubrication pipelines to transmit lubricating oil products. The inner diameter of the lubrication pipelines is less than 10mm, and the pipelines are long. Important parts are not lubricated effectively

There is no selectivity in heat distribution in this way, and it cannot be prioritized, and multi-point selection focuses on the components that need to be temperature compensated.

When the wind turbine is running at low temperature, it cannot guarantee the normal operation of oil products, functional liquids or electrical components that require operating temperature in scattered arrangements (or where the wind is not easy to reach) in the wind turbine.
