Overview
GN19-12ST/400, 630, 1000, 1250 type double-pitch disconnector each phase conductive part is fixed on the chassis by three pillar insulators, GN19-12CST/400, 630, 1000, 1250 type double-pitch three-phase parallel installation, conductive part is made up of contact knife and static head, each phase contact knife is connected with pestle insulator in the middle, tie rod insulator is connected with the main shaft that is installed on the chassis, and the main shaft is connected with the pestle and CS6-1 (T) by the armThe type of driving mechanism is connected, and the operating mechanism is connected to the auxiliary switch together with the linkage lever (provided by the user).
GN19-12ST/1000, 1250 and GN19-12CST/1000, 1250 are installed with magnetic lock pressure plate in contact, and the purpose of adding magnetic lock pressure plate is: when the short circuit current passes, the attraction between the two groove type contact knives is strengthened. It also increases the contact pressure at the contact point, thus improving the dynamic and thermal stability of the switch contact.
