High voltage isolation switch according to the different installation methods can be divided into outdoor and indoor high-voltage isolation switch high-voltage isolation switch. Outdoor high-voltage isolation switch means to withstand wind, rain, snow, filthy, condensation, ice and heavy frost and other effects, suitable for high-voltage isolation switch installed on the terrace for use. Can be divided according to their different single-pole isolation switch (single-column disconnector), double-column disconnectors (double-column disconnector), three-column disconnectors (three-column disconnector) insulation pillar structure. One single overhead busbar disconnectors column directly below the vertical space used as electrical insulation fracture, therefore, has a significant advantage, that is, high-voltage isolation switch Jinhua saving footprint, reducing connection of the wires, and switch on state particularly clear. In case after EHV transmission and substation disconnectors single column, saving an area of ??effect is more significant. Isolation switch conductive portion bent at right angles from a static contact the copper plate, which has a hole at one end can be connected by screws to the bus; the other end of the shorter (Part 1 high-voltage isolation switch, 2) Suzhou high-voltage isolation switch, closing time It is in contact with the moving blades (moving contacts). Composition of two copper contact strip (part 3), also known as the movable contact, pivotally certain angle, when it is clamped closing the stationary contact. There clamp spring (part 4) for adjusting the contact pressure between the fixed and moving contacts between the two copper plates, copper plates at the same time both in the current flowing in the same direction, produces an electromotive force of attraction between them, which increases the contact pressure, improve operational reliability. When the contact strip is mounted at both ends of galvanized steel (Part 6) is called a magnetic lock, which ensures that the fault current flowing through the short circuit, the mutual attraction of the magnetic force generated by the magnetized lock Zhenjiang pressure isolation switch, the contacts of the contact pressure to strengthen , thereby increasing the dynamic and thermal stability of the disconnector.
