GN30-12 improved indoor high voltage isolation switch


GN30-12 improved indoor high voltage isolation switch is improved through the following five innovative technologies:


Technological improvement through innovation in the following five aspects:


✧ original i-section base to improve the use of high purity copper machining, enhance conductivity;


✧ increases static contact load flow cross section;


✧ increase dynamic current-carrying cross-section touch the edge of the sword;


✧ static contact contact means and increase with the cross section can be adjusted connections between bearing, to improve the poor floating point contact conductive;


✧ isolating switch box instead of stainless steel frame, lower frame eddy current heating.



Through type test and field verification, the transformation scheme has remarkable effect and has the following advantages:


✧ using electrolytic copper plate forming processing base, to replace the original cast copper i-section base, improve the whole the conductivity of the static contact;


✧ improved contact and connection structure of the base, isolating contacts in the long run there is enough in the process of conductive ability, connection structure will be high;


✧ increased contact conductive section to ensure that contact has enough current-carrying section;


✧ increase moving contact knife of conductive section, to ensure the moving contact knife has enough current-carrying section;


Contact ✧ retains the original design of the movable connection advantage, increase the adjustable connection has no effect on contact of degrees of freedom, contact and moving contact with the cylinder still has certain self correction ability, also in, brake operation is flexible structure of contact, make contact and moving contact cylinder in, won't appear too much friction brake process. This structure not only ensures that the operating force will not be too large, and there will be no friction loss of the contact plate and the moving contact knife.


✧ not permeability stainless steel material frame to eliminate the eddy current effect in the running fever.


✧ retain the original design of the adjustable connection structure, under the design contact refers to the contact pressure is guaranteed, do not increase the operating force.


✧ without changing the original design of the contact dimension, the scene in the operation modification, isolating switch, can directly replace the static contact, convenient for modification and shorten the blackout time.
