Compared with prior art, the present invention controls linkage action by external switch, linkage drives support insulator around bearing rotary, two support insulator tops of same phase stretch out respectively by plug-in strip and are provided with male contact and female contact, because male contact and female contact lay respectively at the both sides of base, when making support insulator along rotating Vortex, two contacts with plug-in strip from heteropleural in opposite directions or opposing motion, and then realize engaging or being separated, complete combined floodgate and separating brake.With traditional GW
4the mode that isolating switch two insulation column porcelain vase engages from homonymy counter rotating is compared, the present invention can increase dynamic/static contact contact area and contact, and then effectively improve ampacity, reduce contact because of the fault caused of generating heat, ensure grid equipment safe and stable operation.
Further, there is centered by the public contact of the present invention the cylinder of fuse, fuse periphery is annular groove, female contact comprises retainer ring and is uniformly distributed several fingertips be connected to inside retainer ring, two contacts with plug-in strip from heteropleural move toward one another time, fuse can be inserted in the space be formed centrally in fingertip, can insert the retainer ring of band fingertip in annular groove.Adopt the male contact of this column type and the female contact of plum blossom finger-contact type, considerably increasing the contact-making surface of dynamic/static contact, after tested, is approximately former contact GW
4about 3 times of type isolating switch contact-making surface, and the female contact of plum blossom finger-contact type easily increases the pressure of fingertip to male contact, the radius of plum blossom fingertip is larger, and contact-making surface is more, and conductivity is better, and then improves ampacity, reduces the fault that contact causes because of heating.
Further, annular groove edge of the present invention is processed with 45 ° of chamferings, is convenient to public contact and inserts.
Further, retainer ring of the present invention is ring spring, and the setting direction of fingertip is vertical with the deformation direction of ring spring, and fingertip head outside installs contraction spring ring additional can increase the pressure of fingertip to public contact, also convenient maintenance or replacing.
