Disclosed is an integrated automatic system of cooling and fire-fighting for a wind generating set. A circulating cooling loop is composed of a compressor, a condenser, a dry filter, a first check valve, a high-pressure storage tank, a throttling valve, cooling loop gate valves and evaporators. The evaporators are arranged on a gear box, a motor and a converter. A fire-fighting pipeline is connected with the high-pressure storage tank and fire-fighting gate valves. The high-pressure storage tank and the fire-fighting gate valves are led to the gear box, the motor and the converter respectively. A second check valve and a reagent supply branch gate valve are arranged at an inlet of the compressor. Each of the gear box, the motor and the converter is provided with a temperature sensor and a fire detector which send signals to a controller. The controller outputs the signals to control operation of the compressor and drive the cooling loop gate valve, the fire-fighting gate valve and a fire alarm to open. The integrated automatic system of cooling and fire-fighting has the advantages that the cooling and the fire-fighting are integrated, and the cooling agent and the extinguishant are same, complementing each other, thus performance and reliability of the whole system are improved.
Description
technical field [0001] The invention relates to the field of wind power generation, in particular to a cooling and fire-fighting system for a wind power generating set. Background technique [0002] In order to make better use of wind resources and improve power generation efficiency, the capacity of a single wind turbine is getting bigger and bigger, and its heat production is also increasing, which puts forward higher requirements for the cooling system. In addition, the heat generated during the operation of wind turbines is concentrated in some key components, which increases the risk of fire. Moreover, wind farms are mostly built in wild areas, and the distance between the engine room and the ground is high, which also puts forward higher requirements for the fire protection system. [0003] At present, the cooling system of wind turbines mostly uses forced air cooling, and the fire fighting system mostly uses gas fire extinguishing and water mist liquid fire extinguish...
