Specific embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
A part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
Fig. 2 is the flow chart of the detection method of the wind power generating set water-cooling system that the embodiment of the present invention one is provided, such as Fig. 2
It is shown, the method for the present embodiment, including：
Step 101, when water-cooling system meets water-cooled self-inspection condition, obtain the water-cooled liquid in environment temperature and water-cooling system
Temperature.
In the present embodiment, specifically, when the water-cooling system of wind power generating set meets water-cooled self-inspection condition, Ke Yitong
Cross environment temperature sensor to go to obtain environment temperature, go to obtain the water-cooled system of wind power generating set by water-cooled liquid temperature sensor
Water-cooled liquid temperature degree in system.
Step 102, it is determined that environment temperature be less than the first preset temperature when, successively open water-cooling system heating detection,
The radiating detection of water-cooling system.
Wherein, the first preset temperature is 30 degree,
In the present embodiment, specifically, because blower fan water-cooling system is not air-conditioning system, maximum heat-sinking capability be exactly with outward
Boundary's temperature maintains an equal level.So when only water-cooled liquid temperature degree is higher than environment temperature, the radiating of water-cooling system just can be effective.And it is right by radiating
As the optimum operation temperature of current transformer is between 30~35 degree, this just determines that water-cooled liquid temperature degree is preferably kept in 30 to 35 degree
Between.Meanwhile, if in order to test water-cooling system heat-sinking capability for a period of time, it is necessary to make environment temperature less than water-cooled liquid temperature degree,
If both differences select 5 degree, environment temperature needs 25~30 degree.
Whether less than the first preset temperature, first preset temperature can be 30 degree to the environment temperature that judgement gets, if
The environment temperature for getting is less than 30 degree of the first preset temperature, it is possible to first turn on the heating detection of water-cooling system, Ran Houkai
Open the radiating detection of water-cooling system.
Step 103, it is determined that environment temperature is more than the first preset temperature, and water-cooled liquid temperature degree subtracts what environment temperature was obtained
When difference is more than preset temperature difference, radiating detection, the heating of the water-cooling system detection of water-cooling system are opened successively.
Wherein, the first preset temperature is 30 degree, and preset temperature difference is 5 degree.
In the present embodiment, specifically, whether judging the environment temperature for getting more than 30 degree of the first preset temperature, and lead to
