BURSTING PLATE, BURSTING APPARATUS AND GAS-INSULATED SWITCHING APPARATUS USING THE BURSTING PLATE

摘要

PROBLEM TO BE SOLVED: To solve the problem, wherein conventional outdoor-installed gas-insulated switching apparatuses have problem with long-term reliability, because the bursting plate of the bursting apparatus as one component is corroded by wetting on a rainy day or the infiltration of humidity or is expanded by icing of its wet portion, thus accelerating the deterioration in the strength in its expanded portion.;SOLUTION: Hydrophobic synthetic resin is brought into close contact with an atmospheric-side surface of the bursting plate for blocking a bursting hole formed in the gas-insulated switching apparatus, to prevent the infiltration of rain or humidity into the surface of the bursting plate, thus inhibiting acceleration of corrosion or deterioration of strength for high long-term reliability of the gas insulated switching apparatus.;COPYRIGHT: (C)2010,JPO&INPIT
