Arc extinction device of gas-blast load-break switch

摘要

(57) Abstract Objective When opening and closing the gas-blast load-break switch (cutoff) performance is raised, sameThe time the operational electrode and chattering of the fixed electrode are prevented. Constitution Restoration arc-extinguishing gas 3, inside case 2 where it closes airtightThrough the bush, the fixed electrode which is jointed to central conductor 612 distribution facilities is done. In addition as for the operational electrode 9 which opposes to this 2It consists of parallel electric conduction board 8, the in electric conduction board 8 the electric conduction board phaseHaving the spring component 16 which energization is done for inner split direction between the , the above-mentioned fixingThe it makes the contact section 12of a the edge strip of electrode contact 12 holding.Furthermore on the above-mentioned fixed electrode side contact section of the above-mentioned both electric conduction board 8,82 the passing 8b and 8b is allowed V letter or the U letter channel 2Multiple grid boards 21 which formed 1a are done lamination distribution facilities,It is.
