when the delta I is less than or equal to I1, selecting a first preset compensation coefficient c1 to compensate the real-time temperature of the corrected lower area, wherein the compensated temperature is delta T03 ai c 1;
when I1 is smaller than delta I and smaller than or equal to I2, a second preset compensation coefficient c2 is selected to compensate the real-time temperature of the corrected lower area, and the compensated temperature is delta T03 ai c 2;
when I2 is smaller than delta I and smaller than or equal to I3, a third preset compensation coefficient c3 is selected to compensate the real-time temperature of the corrected lower area, and the compensated temperature is delta T03 ai c 3;
when I3 is smaller than delta I and smaller than or equal to I4, a fourth preset compensation coefficient c4 is selected to compensate the real-time temperature of the corrected lower area, and the compensated temperature is delta T03 ai c 4;
after the ith preset compensation coefficient ci is selected to compensate the real-time temperature of the corrected lower area, i =1, 2, 3, 4, the compensated temperature is delta T03 ai ci and is compared with Tb3 again, if delta T03 ai is more than Tb3, all electric equipment in the cabinet is closed, and an alarm is given; if Δ T03 × ai is less than T3, the operations are performed at Δ T01 > Tb1, Δ T02 > Tb2, and Δ T03 is less than or equal to Tb 3.
