Embodiment
By describing technology contents of the present utility model in detail, realized object and effect, accompanying drawing is coordinated to be explained below in conjunction with execution mode.
The design of the utility model most critical is: the electric-conductor of the utility model pipe contact box is circular tube shaped, and its Electric Field Distribution is even, and phenomenon is put in the office decreasing old-fashioned contact box connected mode, improves the operational reliability of equipment for power transmission and distribution.
Please refer to Fig. 2, Fig. 3 and Fig. 4, a kind of pipe contact box, comprise hollow box 5 and circular tube shaped electric-conductor 6, the side of one end of described hollow box 5 is provided with the through hole 51 matched with circular tube shaped electric-conductor 6, described circular tube shaped electric-conductor 6 is arranged on described hollow box 5 through through hole 51, the shape that described circular tube shaped electric-conductor 6 is positioned at hollow box 5 exterior section is circular tube shaped, the shape that described circular tube shaped electric-conductor 6 is positioned at hollow box 5 interior section is the flat of the flat rear formation of pipe pier, one end that described circular tube shaped electric-conductor 6 is positioned at the flat of hollow box 5 is provided with fixed contact 61, the other end is provided with main bus bar 7.
From foregoing description, the beneficial effects of the utility model are: because the electric conductor of pipe contact box uses pipe, its Electric Field Distribution is even, phenomenon is put in the office decreasing old-fashioned contact box connected mode, improve the operational reliability of equipment for power transmission and distribution, and greatly save the use amount of non-ferrous metal.
Further, above-mentioned pipe contact box adopts epoxy resin integrated casting shaping; Pipe contact box flange end (side of the other end of described hollow box opposing through-bores) is cast on flange face by four uniform inserts 53, inserts 53 has been attacked screwed hole 531; Pipe contact box front end is designed for arc surface, is applicable to rotary valve and Direct Action Type valve; The through hole 51 that pipe contact box rear end is connected with electric-conductor adopts rhombus design, and the profile of the flat rear self-assembling formation of pipe pier that coincide, ensures the degree of protection between compartment.
Further, inside above-mentioned pipe contact box, rear end (inwall that described hollow box is provided with one end of through hole is appeared on the stage) is provided with a boss 52, in boss 52, cast copper insert 521, copper insert 521 has attacked screw thread hole, for the circular tube shaped electric-conductor 6 that fastening pier is flat.
Further, above-mentioned pipe contact box outer upper has the first shirt rim 54 of four crescent shapes, increases contact box outer downside creepage distance.
Further, above-mentioned pipe contact box inside front ends is provided with the second shirt rim 55 of ring-type, increases the creepage distance inside contact box;
