Abstract
The utility model discloses metal armored movable high-voltage switching equipment, which comprises a contact box (2). A static contact device (5) and a bus (1) are fixed in the contact box (2); the bus (1) is tightly connected in the contact box (2) through a contact box mounting hole (3), the static contact device (5) and a bus fixing hole (6); and edge angles at two ends of the bus (1) have smooth arc structures (4), the smooth arcs are formed by chamfers at the edge angles of the two ends, and the radii of the chamfers are preferably R30mm fillets. The edge angles at the two ends of the bus in the contact box of the metal armored movable high-voltage switching equipment have the smooth fillet structures, so point discharge can be effectively prevented, and the stability of the whole system is greatly promoted.
Description
Technical field
The utility model relates to a kind of metal-clad moveable formula high voltage switchgear.
Background technology
Metal-clad moveable formula switchgear is applied in the 3-110KV power supply and distribution of electric power system more and more widely.Important component part--the contact box of metal-clad moveable formula switchgear, its inner busbar of installing all adopts rectangular configuration, and there are corner angle in two ends, externally under the situation of running environment fluctuation, these edges and corners very easily produce point discharge phenomenon, thereby influence the stability of whole system.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of metal-clad moveable formula high voltage switchgear at problems of the prior art, its objective is the stability of avoiding influencing owing to the point discharge that the busbar edges and corners produce whole system.
The technical solution of the utility model is this kind metal-clad moveable formula high voltage switchgear, comprise contact box, the internal fixation of described contact box has static contact head device and busbar, described busbar is connected in the contact box closely by contact box installing hole, static contact head device and bus fixing hole, and the edges and corners, two ends of described busbar are smooth arc structure.
Smooth circular arc on the described busbar promptly is by forming in edges and corners, two ends chamfering.
Described chamfering scope is that radius is the fillet of R10mm-R50mm.
Described chamfer radius is preferably the fillet of R30mm.
This kind metal-clad moveable formula high voltage switchgear can also be: the smooth circular arc on the described busbar is the protective layer that is provided with in the edges and corners, two ends of busbar with smooth fillet.
The scope of the radius of corner on the described protective layer is R10mm-R50mm.
Radius of corner on the described protective layer is 30mm preferably.
A kind of metal-clad moveable formula high voltage switchgear with above-mentioned special construction has the following advantages:
1, the two ends corner angle of the busbar in this kind metal-clad moveable formula high voltage switchgear contact box adopt smooth fillet structure, can effectively prevent the generation of point discharge phenomenon, have promoted the stability of whole system greatly.
2, the processing structure of busbar is simple in this kind metal-clad moveable formula high voltage switchgear, and effect is superior, has good application and popularization value.
