Abstract
The invention discloses a shielding contact box which comprises a contact box body. The contact box body is provided with a bus outlet groove. The but outlet groove protrudes slantingly leftwards or rightwards. The shielding contact box has a reasonable structure. An air creepage distance between three phases of contact boxes is effectively increased. The insulating coefficient is high. Clapboards are not required among the three phases of contact boxes. The flame retardant property is good.
Description
Technical field
The present invention relates to the contact box that a kind of switch cubicle uses.
Background technology
The contact box that existing switch cubicle uses, its busbar go out wire casing and are the angle consistent with last bottom plate and stretch out, during use, between the three-phase contact box dividing plate need be set, because of the material of dividing plate and air distance do not reach standard, during work, easily heating causes accidents such as burning.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructure, the shielding contact box that air distance is big between the three-phase contact box, safety in utilization is good.
Technical solution of the present invention is:
A kind of shielding contact box comprises the contact box body, on the contact box body bus is set and wire casing, it is characterized in that: busbar goes out that wire casing is to the left or the oblique form of stretching out in right side.
The oblique angle of inclination of stretching out that described busbar goes out wire casing is 8 ° ~ 15 °.
Described contact box is the contact box in the left side in the three-phase contact box, and its busbar goes out that wire casing is oblique to the left to be stretched out; Or described contact box is the contact box on the right side in the three-phase contact box, and its busbar goes out that wire casing is oblique to the right to be stretched out.
The present invention is rational in infrastructure, has effectively increased the air creepage distance between the three-phase contact box, and the insulating coefficient height need not dividing plate between the three-phase contact box, and fire resistance is good.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
