Description
Technical field
The present invention relates to a kind of Rustproofing apparatus, iron tower of power transmission line bottom column material corrosion device is specifically prevented.
Background technology
The current power transmission line steel tower overwhelming majority is angle steel tower, is exposed to for a long time in large natural environment.Current Shandong District
Run time most long 500kV transmission lines of electricity nearly 30 years, the earliest 500kV transmission lines of electricity in Linyi Prefecture such as you transported according to I line
Row was more than 15 years.Due to some following reason, steel tower bottom column material with cement protective cap contact position nearby seriously become rusty by generally existing
Erosion situation：Water at cement protective cap：Due to the old all planar designs of circuit protective cap, hold around the main material of steel tower bottom
Easy ponding, such as acidic rain water, long term causes and the tower material corrosion of protective cap contact position；Coefficient of expansion difference causes protective cap
Occurs infiltration gap between tower material：Simultaneously gap is not present in script cement protective cap and angle steel, but due to material different heat expansion system
Number is different, adds and is exposed to for many years under large natural environment, causes occur trickle gap, acid rain between cement protective cap and tower material
Water, humid air etc. cause further corrosion to bottom column material after penetrating into；Tower material corrosion is accelerated in the accumulation such as stalk, debris：According to
Transmission line of electricity operating standard, does not allow have the accumulation situations such as stalk, native stone debris at tower leg.But every transmission line of electricity is at least several
The base steel tower of ten milimeter number hundred, typically has four tower legs per base steel tower, therefore packing phenomenon is difficult to avoid completely.Due to stalk corrosion
And local humid air effect, further speed up the speed of steel tower bottom column material corrosion.
The content of the invention
It is an object of the invention to provide iron tower of power transmission line bottom column material corrosion device is prevented, above mentioned problem can solve the problem that.
The present invention to achieve the above object, is achieved through the following technical solutions：Prevent iron tower of power transmission line bottom column material from becoming rusty
