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). The conductive part is mainly composed of the contact knife and the static contact, the static contact is installed on the pillar insulator at both ends, and each phase contact knife is composed of two groove pictures, it not only increases the contact knife dispersion area, is beneficial to the low temperature rise, and the mechanical strength of the contact knife is raised, the dynamic stability of the switch is improved, one end of the contact knife is installed on the static contact by the pivot pin (bolt), and the other end of the contact knife can be connected separately with the static contact system, and the contact pressure of the contact knife is maintained by the contact spring at both ends.
