Product isolation switch roughly Commentary: From a copper plate bent at right angles constitute static contact with a hole at one end which can be connected by means of screws to the bus; other end of the shorter (parts 1 and 2), closing the movable blade when it (moving contact) contact. Two copper contact strip composition (part 3), also known as the movable contact, to a certain angle about the axis, when it is clamped stationary switch contacts. Clamped between two copper spring (part 4) for adjusting the contact pressure between the contact movement, while two copper, the current flowing in the same direction when they are attracted to each other between the electromotive force, which increases the contact pressure, improved operational reliability. Attached to both ends of the contact strip galvanized steel (Part 6) is called the magnetic lock, which ensures fault current flowing through the circuit, the magnetic lock magnetized mutual attraction force produced enhance contact of the contact pressure, thereby increasing the disconnector dynamic and thermal stability. 2 insulating portion 2. Insulation parts are fixed to the two static and dynamic contact support insulator (Part 12). For models with C, the moving contact tube fixed on porcelain. In order to make the moving contact and metal, grounded insulated transmission part, using a ceramic insulating rod insulator (Part 7). 3 Transmission section 3. Drive part the spindle, crank arm, rod insulators. 4 base part 4. Base part composed by a steel frame. Support porcelain vase and the drive shaft or sleeve are fixed on the base. Base should be grounded. In short, the isolation switch simple structure, no interrupter device, when in the open position with a clear break point, the division and the state is very intuitive.
