Embodiment Construction
[0038] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0039] Such as figure 1 As shown, an intelligent control method for a transformer cooler includes the following steps:
[0040] 1. The sensor collects the real-time temperature T of the transformer winding in real time;
[0041] 2. Set the constant temperature value for transformer operation, the constant temperature value is 50°C;
[0042] 3. The control unit determines the cooler control strategy based on the real-time temperature T of the transformer winding and the temperature change rate DT / Dt in step 1, where DT=△T is the temperature change, Dt=△t is the time interval, in order to avoid fre...
