Structure features of series iron shell switch/iron shell load switch/fuse type load switch
The iron shell switch is mainly composed of four parts: contact arc extinguishing system, fuse, operating mechanism and shell. The arc extinguishing chamber is made of arc-resistant plastic and has a simple mechanism that is easy to disassemble and assemble. The contact system adopts a double-breakpoint direct-acting long contact type. The moving contact is a double-breakpoint contact with a stuffed-sealed tubular fuse as the bridge arm. The long contact has high electric stability. , double breakpoints have higher breaking ability. The ultimate breaking capacity of stuffed sealed tube fuses reaches 1,000 amps, which can meet the requirements of general power grids. The operating mechanism adopts a single-rod pull-out structure and spring energy storage principle. The same spring is used to perform the on and off functions of the switch, ensuring that the switch can be reliably connected and disconnected, and has an obvious on and off mark. The pull-out operating handle can be pushed into the switch housing after the switch is turned on or off. It has a beautiful appearance. The switch cover is equipped with an interlocking device to ensure that the switch cannot be turned on after the cover is opened and the cover cannot be opened after the switch is turned on.
