Description

Binary channels low voltage bus bar groove

Technical field

The utility model relates to equipment for power transmission and distribution, specifically a kind of binary channels low voltage bus bar groove.

Background technology

Current existing conventional low voltage bus duct, its cross section structure usually as shown in Figure 1, its inner A, B, C, N tetra-phase conductor is all in an outer shell passage, the heat produced in causing middle two phase conductors to run is difficult to distribute, thus make the temperature rise of middle two-phase apparently higher than outside two-phase, the higher meeting of temperature rise causes the comparatively fast aging of this two-phase insulating material, and the risk of the accident that is short-circuited also increases thereupon.In addition, metal shell bus duct in the market has obvious weakness in water resistance, main because the unavoidable apertured existence of assembling between metal shell, the main cause that namely these gaps cause bus duct degree of protection to reduce just.

Summary of the invention

Technical problem to be solved in the utility model is, provides a kind of each phase conductor heat-sinking capability strong, the binary channels low voltage bus bar groove that water resistance is good.

Binary channels low voltage bus bar groove of the present utility model comprises two capsomeres be arranged side by side, two-phase bus-bars conductor is mounted with in each capsomere, two-phase bus-bars conductor near two sidewalls of capsomere, is connected as one by coupling part between two capsomeres respectively.

Described coupling part comprises the multipair connecting plate being positioned at the upper and lower and longitudinal separation of capsomere and arranging, connecting plate both sides are riveted fixing respectively with the end face of two capsomeres or bottom surface, a pair connecting plate and a contiguous block be clipped between two capsomeres are connected by screw fixing.

Described coupling part can also be connected gusset with the parts of two capsomeres are integrated.Described connection gusset can be positioned in the middle part of capsomere or upper and lower two ends.

The cross sectional shape of each capsomere is involuted with the inner housing being positioned at inner side by the shell body being positioned at outside, described inner housing cross sectional shape is C shape, the cross section of shell body is upper and lower is respectively arranged with the slot with inner housing edges co-operate, and inner housing edge inserts described slot and is pressed on the sealing strip that is positioned at bottom slot and realizes being tightly connected.

Each capsomere can also be formed to the wallboard that opening cross section is toward the outer side c-shaped is mutually nested from side by two, the top of two wallboards and bottom riveting respectively.

The outer surface of described capsomere is provided with heat radiation teeth groove.

The utility model have employed binary channels form and is separated by four phase conductors, every root conductor is made all to have the heat-dissipating casing be adjacent, can effectively reduce bus duct internal temperature rise, and the assembling of each monomer have employed the combination of grafting nested mode, a large amount of bolts and rivet are abandoned, and utilize sealing strip to play good sealing function at the binding site of nested structure, thus improve the barrier propterty of bus duct.
