The high-security communication board card for the intelligent substation comprises the following steps:
S1, after the board main body 1 is used for a period of time, the environment where the board main body 102 is located can be selectively dehumidified;
s2, referring to FIG. 8, firstly, the air pump 10 on the auxiliary hollow column 8 is started to pump out the air in the hollow soft belt 51 to enable the air to be in a shrinking state, then the main motor 701 is started to enable the main hollow column 7 to slightly unwind the hollow soft belt 51, so that the absorbent cotton layer 52 and the hollow soft belt 51 on the lower side thereof are loosely positioned above the board main body 102 and far away from the lower surface of the moisture collecting sheet 4;

S3, referring to FIG. 9, the refrigerating sheet 3 is started to refrigerate the moisture collecting sheet 4, so that moisture in the upper space of the board card main body 102 is condensed into water drops on the lower surface of the low-temperature moisture collecting sheet 4, after a period of time, the main motor 701 is started to slightly wind the hollow soft belt 51 by the main hollow column 7 (the winding length is the same as the unreeling length in S2), and the absorbent cotton layer 52 is stretched back to the original position, contacts with the lower surface of the moisture collecting sheet 4 and absorbs the water drops;
Supplementary explanation: in the specific implementation process, under the condition of not influencing the use, the thickness of the moisture collecting sheet 4 is reduced to the greatest extent, so that condensed water drops at the side end of the moisture collecting sheet 4 are negligible, and in the tightening process, the moisture absorbing cotton layer 52 is extruded to a certain extent when being contacted with the moisture collecting sheet 4 by combining the hollow soft belt 51, so that the moisture collecting sheet 4 is sunk into the moisture absorbing cotton layer 52 to be contacted with the side end of the moisture collecting sheet 4 to a certain extent, the water drops at the side end of the moisture collecting sheet 4 are absorbed, and the moisture drops are not easy to be generated, so that the moisture collecting sheet 4 indicates the water drops are remained;
