Description
Technical field
The utility model relates to DC power transmission line anti-electrocorrosion technical field, specially a kind of DC power transmission line porcelain
The double bolt formula zinc ring of insulator.
Background technique
Under moist or condition of raining, porcelain insulator chapeau de fer is easy to appear galvano-cautery phenomenon, and the corrosion products such as iron rust are exhausted
The accumulation of edge part surface, so that insulator surface becomes coarse, insulator surface is easier contamination, when insulator surface has a constant volume
Dirty situation, insulator surface again by the weather such as mist, dew, drizzle influenced sufficiently to make moist and the leakage distance of insulator compared with
It is small, therefore insulator equipment surface forms one layer of conductive moisture film, corresponding leakage current is larger, and Leakage Current is passed through by chapeau de fer
When crossing cement inflow steel feet, since the current potential of chapeau de fer is larger, the metal ionization of chapeau de fer is dissolved gradually, to generate electrochemistry rust
Erosion.
2 months 2012, operation maintenance personnel was during ± 800kV gives line interruption maintenance again, discovery #957-#965 tower pendency V string
There are chapeau de fers to corrode situation on the insulator chain of porcelain insulator string and suspension wire jumper, and 2012 same to line #957-#965 is given again
Section porcelain insulator is once installed additional the improvement of shape of a hoof zinc ring excessively, gives direct current again in 800kV and chapeau de fer occurs in March, 2013
Recognize when the #957-#965 section investigation of corrosion, after installing anti-corrosion shape of a hoof zinc ring additional and running 1 year, gives engineering porcelain insulating again
Son does not find that chapeau de fer corrodes, and phenomenon fully confirms effective anti-corrosion property of anti-corrosion zinc ring, and operation maintenance personnel makes an inspection tour hair within 2017
Existing, #957-#965 sections of porcelain insulator zinc rings fell off by 5 years operation part shape of a hoof zinc rings, and insulator cap meets with
By the increased risk of galvano-cautery, the safe operation for giving line again is influenced.
Existing market application design scheme is installed in the Direct-current porcelain insulator that original does not install zinc ring, and the shape of a hoof is designed as
To install, chapeau de fer surrounding electric field is not also generated and is significantly affected,《± 400~± 800kV suspension type of dc disc shape porcelain/glass is exhausted
Edge general technology specification》Providing the zinc material manufacture that zinc ring should be not less than 99.95% using purity, high-purity Zn ring is more crisp,
Easily soften under hot environment, shape of a hoof zinc ring does not form 360 ° of full encirclements to porcelain insulator, therefore original gives line # in 12 years again
There is obscission in the part 957-#965 porcelain insulator zinc ring.
