Abstract
A high-insulation system fuse unit comprises a fuse unit body, a contact box and a porcelain bottle sleeve. 5-7 umbrella skirts are arranged on the surface of the fuse unit body and positioned between the contact box and the porcelain bottle sleeve. The umbrella skirts are added, the creepage distance of the high-insulation system fuse unit is increased, insulators cannot be broken down in a damp or heavily polluted environment, skirt edges are smooth, point discharge is avoided, a circuit can be rapidly cut off under the condition of short circuit or overload, and use safety of products in the damp or heavily polluted environment is improved.
Description
technical field:
The present invention relates to a kind of high voltage electric equipment, especially relating to a kind of high insulation is fuse unit.
background technology:
Along with expanding economy, power equipment safety and electric power netting safe running are the targets that electric power enterprise is pursued, the safe operation of high-tension apparatus is the basis of whole system safe operation, if there is defect in inside, the accident of equipment and electric power netting safe running can make a difference, for fuse unit, its insulation crust is generally all exposed in air, and the external world exists dust, the problems such as humidity, especially polluting comparatively serious area, traditional fuse unit is often because creepage distance is inadequate, finally cause insulating part breakdown, the very possible like this serious consequence that causes, have a strong impact on staff's statement safety.
summary of the invention:
In order to overcome above-mentioned deficiency, the invention provides a kind of high insulation is fuse unit.The technical solution adopted for the present invention to solve the technical problems:
A kind of high insulation is fuse unit, comprising: fuse stack shell, contact box and porcelain bottle sleeve, described fuse stack shell surface is provided with full skirt.
The quantity of described full skirt is 5-7.
Full skirt is between contact box and porcelain bottle sleeve.
Owing to adopting technical scheme as above, the present invention has following superiority:
A kind of high insulation of the present invention is fuse unit, increase Liao Ji road full skirt, thereby increase its creepage distance, avoid under the environment of humidity or heavily contaminated insulating part not breakdown, shirt rim is round and smooth, also avoid occurring point discharge phenomenon, occur cutting off rapidly circuit under short circuit and overload situations at circuit, improve the safety in utilization of product in wet environment or seriously polluted area.
brief description of the drawings:
Fig. 1 is sectional view of the present invention;
Fig. 2 is schematic diagram of the present invention;
In figure: 1, fuse stack shell; 2, contact box; 3, porcelain bottle sleeve; 4, full skirt.
embodiment:
Can explain in more detail the present invention by embodiment below, disclose object of the present invention and be intended to protect all changes and improvements in the scope of the invention, the present invention is not limited to the following examples;
The high insulation of one shown in 1 is fuse unit by reference to the accompanying drawings, comprising: fuse stack shell 1, contact box 2 and porcelain bottle sleeve 3, described fuse stack shell surface is provided with full skirt 4.
The quantity of described full skirt 4 is 5-7.
Full skirt 4 is between contact box 2 and porcelain bottle sleeve 3.
In above content, carefully do not state part for prior art, state therefore do not run business into particular one.
