It helps, is easy to operate, adapting to the features such as outdoor environment is strong, being widely used in 10kV distribution lines and distribution transformer primary side
It is used as protecting and carry out equipment throwing, cut operation.But because fuse switch is to work outdoors, exposed working device
Part is often subjected to the invasion exposed to wind and rain with dust, leads to that device gets rusty or interconnecting piece cannot be rapidly separated, and fuse cannot
Normal work.
Utility model content
In consideration of it, the utility model provides a kind of fuse switch.
Its technical scheme applied to solve the technical problem is：A kind of fuse switch, including shell and fuse protection
Device, which is characterized in that the shell is equipped with side door, line outlet, fuse and falls mouth, and the fuse protecting device includes upper wiring
Terminal, pressure release emit, upper cover, upper contact head, upper dynamic contact rod, cartridge fuse, secondary spring, tripping device, under quiet connector, lower terminals
Son, high strength insulator；The high strength insulator is fixed on the housing, and the upper cover connects with the upper connecting terminal
It connects, upper contact head is connect with the upper connecting terminal, and the cartridge fuse is fixed between the upper cover and tripping device, the auxiliary
Spring quiet connector under is connect.
Preferably, the high strength insulator is fixed on the housing by rigid insulation plastics.
Preferably, the upper connecting terminal is to be bolted with upper cover connection type.
Preferably, quiet joint surface carries out silver-plated process under described, and silver-plated depth is 3 μm.
Preferably, the upper connecting terminal is designed with lower connecting terminal using double flute, the upper connecting terminal and lower wiring
Terminal surfaces are tin plating, and depth is 3 μm.
Preferably, the line outlet is equipped with baffle with side door.
Preferably, top is pyramidal structure on the shell.
The beneficial effects of the utility model are：Shell can stop influence of the external environment to fuse, avoid device
Corrosion and dust entrance, meanwhile, secondary spring can enhance tripping device and in circuit encounter short circuit and when overload situations, fuse
Pipe falls ability, and securely and reliably, service life is long.
