Background technology
Medium pressure gas insulated switching installation (MV-GIS) is a kind of switchgear obtaining at home nearly ten years developing rapidly, is widely used in fields such as power transmission and distribution, petrochemical industry, track traffic, high ferros.After MV-GIS arranges at the scene, the connection of main bus bar is the important step realizing primary distribution system safe and reliable operation, is also the principal element determining MV-GIS performance parameter.
The solution that existing market Up Highway UHW connects has many, mainly contains:
1. bolt connects.This structure ubiquity requires that space is large, and electric field is uneven, and needs bus at the scene to carry out vacuumizing charge operation after connecting, and this not easily accepts from the angle of environmental protection;
2. be connected main bus bar with sleeve pipe with plug-in contact.This structure is subject to the restriction of contact pressure, and ampacity is less, and high to the flatness requirement of in-site installation ground, and the volume of large current-carrying connector is comparatively large, and needs to take extra cooling provision;
3. independent of the solid bus-bar system outside air chamber.This solution cost is very high, will realize in addition running requirement to various primary power distribution scheme, and structure is more complicated, and on-site installation work amount is large and require high;
4. the support of screw lever connects formula bus tie.This structure is subject to the restriction of shape of generatrix and insulation system, and current-carrying cross section is less, and the pressure of contact point is less, and therefore ampacity is restricted.
Traditional control cubicle bus tie structural design is simple, of long duration, very easily gets loose, causes potential safety hazard; The material of tradition fixed mount often adopts permeability magnetic material, electric current by time can produce eddy current, thus interference supply power voltage is stable.But due to the particularity of MV-GIS, it is little that method for connecting bus exists ampacity, difficulty is installed, affects environment because of scene inflation, manufacture or the high deficiency of operating cost.
Utility model content
