In recent years, in the operation troubles of high-tension switch cabinet statistics, fault isolating switch occupies prodigious ratio, especially
Heavy current disconnecting switches（Rated current 3150A or more）It is typically employed in be lower incoming line cabinet or mother segmentation cabinet, once occur
Quality problems will seriously affect the safe and stable of power grid.The more reason of heavy current disconnecting switches failure is summarized, is mainly had
Three aspects：First, GN30 has been approached 30 years from popularization and application are designed into, Earlier designs carry certain limitation；Second is that in recent years
Load increases sharply；Third, the operation time limit is longer, operational process lacks enough maintenances.Above-mentioned three aspects reason, common manifestation
It is excessively high for disconnecting switch longtime running medium temperature liter, and finally cause mechanical breakdown, insulation fault.
Disconnecting switch how is improved, the running Wen Sheng of heavy current disconnecting switches is reduced, is being transported to improve disconnecting switch
Safety, reliability in row, are of great significance.
