Abstract
The utility model relates to a heat conduction type bus duct which is used in a power transmission and distribution system. The heat conduction type bus duct comprises a housing, and multiphase conducting bars disposed in the housing. At least one phase of the conducting bars is composed of two parallel half-sheets, wherein a heat conducting plate is clamped and fixed between the two half-sheets; and two side edges of the heat conducting plate are close to wall plates of the housing. Through the arrangement of the two-sheet type conducting bars, the heat conduction type bus duct obtains a larger surface area with the same sectional area, and thus helps to improve the current-carrying capacity of the conducting bars, reduce the material consumption of conductors and reduce the cost; and through the arrangement of the heat conducting plate, the heat of the conducting bars can be transferred to the housing relatively fast, and thus the heat radiation capability of the entire bus duct is improved.
Description
Technical field
The utility model relates to a kind of heat-conducting bus duct for electrical power trans mission/distribution system.
Background technology
Bus duct in electrical power trans mission/distribution system generally includes housing and is placed in the heterogeneous bus in housing, and each phase bus adopts the busbar of single square-section conventionally.Due to the kelvin effect of power transmission conductor in transmission of electricity process, and the surface area limitation of busbar the raising of its current capacity, thereby it is long-pending to increase cross-sectional area of conductor, thereby improves the cost of product.In addition, the housing sealing in traditional bus duct structure makes conductor heat radiation more difficult, has affected the reliability service of equipment.
Summary of the invention
Technical problem to be solved in the utility model is, provides that a kind of current capacity is strong, material consumption is few, the heat-conducting bus duct of good heat dissipation effect.
Heat-conducting bus duct of the present utility model includes housing and is arranged on the heterogeneous busbar in housing, in described busbar, have at least one by two and half sheets that walk abreast, to be formed, between two and half sheets, gripped a heat-conducting plate, the both sides of the edge of heat-conducting plate are near the wallboard of housing.
On the wallboard of described housing, be provided with the radiating fin corresponding with heat-conducting plate position.
The utility model, by the busbar of two-piece type is set, can obtain larger surface area, thereby improve the current capacity of busbar under same sectional area, has reduced conductor material consumption, has reduced cost; By heat-conducting plate is set, makes the heat of busbar can pass to quickly shell, thereby improved the heat-sinking capability of whole bus duct.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
