Abstract
The utility model discloses a tubular bus with inner and outer circles in different shapes, and the bus comprises a tube-shaped bus. The inner circle of the tube-shaped bus is provided with length-through convex ribs which are uniformly arranged along the axial direction. The convex ribs are uniformly arranged in a symmetrical manner on a cross section. The cross sections of the convex ribs are fan-shaped or polygonal. The bus provided by the utility model not only improves the rigidity, enables the deflection to be controlled within the specification requirements, thereby guaranteeing that the joint of the bus is not deformed on the whole and the contact is good; but also enables the current-carrying capacity to be improved exponentially, the skin effect to be lower, power loss to be less, heat dissipation conditions to be better, the temperature to be lower, and the reliability to be higher.
Description
Technical field:
The utility model relates to a kind of inner circle special-shaped tubular tubular bus.
Background technology:
The tubular bus adopting is at present ganoid pipe mostly, and according to the size of the electric current and voltage of carrying, decide cross section and diameter and the wall thickness of pipe, along with the diameter of the increase tubular bus of electric current and voltage grade also increases thereupon, not only increase manufacturing cost and project cost, and cannot meet the specification requirement of electric power system, so existing tubular bus is limited in 35KV electric pressure substantially with interior use.In addition, existing tubular bus can sagging generation amount of deflection when large span, and amount of deflection surpasses setting and causes bus junction to produce distortion and loose contact and cause overheated overvoltage, causes the accident.
Summary of the invention:
The technical problem that the utility model solves: design a kind of inner circle special-shaped tubular tubular bus, not only improved the rigidity of bus, its amount of deflection is controlled in code requirement, guarantee that bus junction is substantially indeformable and contact well; And ampacity had increase at double, kelvin effect is lower, and power loss is less, and radiating condition is better, and temperature rise is lower, and reliability is higher.
Technical solution of the present utility model: a kind of inner circle special-shaped tubular tubular bus, comprise tubular bus, in the inner circle of described tubular bus, there is vertically evenly distributed elongated convex tendon.
Described convex tendon is symmetric arrays on cross section.
The cross section of described convex tendon is fan-shaped or polygon.
The quantity of described convex tendon is at least 2.
The quantity of described convex tendon is preferably 6.
The advantage that the utility model compared with prior art has and effect:
1, under tubular bus external diameter, internal diameter and wall thickness specifications the same terms, when electric pressure is identical, because the current-carrying face of electric current increases 3-6 doubly than existing tubular bus is maximum, therefore, the ampacity maximum that the utility model is compared with existing tubular bus has improved 3-6 doubly, and kelvin effect is lower, power loss is less.In like manner, under electric pressure and ampacity the same terms, the utility model is compared caliber and has been dwindled 3-6 doubly with existing tubular bus, can meet higher electric pressure and larger ampacity.
2, owing to thering is vertically evenly distributed elongated convex tendon in the utility model inner circle, there are many and support beam action, improved the rigidity of tubular bus, its amount of deflection when large span is controlled in code requirement, guarantee that tubular bus junction is substantially indeformable and contact well, meeting the specification requirement of electric power system.
3, owing to thering is vertically evenly distributed elongated convex tendon in the utility model inner circle, on cross section, formed polygonized structure, cross-ventilation space and speed and cooling surface area have been expanded, under equal service condition, ventilation and heat performance is better than existing tubular bus greatly, has therefore reduced rate of failure.
Accompanying drawing explanation:
Fig. 1 is contour structures schematic diagram of the present utility model,
Fig. 2 is cross section structure schematic diagram of the present utility model.
Embodiment:
1,2 a kind of embodiment of the present utility model is described by reference to the accompanying drawings.
An inner circle special-shaped tubular tubular bus, comprises tubular bus 1, has vertically 6 evenly distributed elongated convex tendons 2 in the inner circle of described tubular bus 1.Described convex tendon 2 is symmetric arrays on cross section, and the cross section of described convex tendon 2 is fan-shaped.
The utility model is under tubular bus external diameter, internal diameter and wall thickness specifications the same terms, when electric pressure is identical, because the current-carrying face of electric current increases 3 times than existing tubular bus is maximum, therefore, the ampacity maximum that the utility model is compared with existing tubular bus has improved 3 times.In like manner, under electric pressure and ampacity the same terms, the utility model is compared caliber and has been dwindled 3 times with existing tubular bus, can meet higher electric pressure and larger ampacity.In addition, owing to thering is vertically evenly distributed elongated convex tendon in the utility model inner circle, on cross section, formed polygonized structure, not only improved the rigidity of tubular bus, its amount of deflection when large span is controlled in code requirement, guarantee that tubular bus junction is substantially indeformable and contact well, meeting the specification requirement of electric power system; And expanded cross-ventilation space and speed and cooling surface area, under equal service condition, ventilation and heat performance is better than existing tubular bus greatly, has therefore reduced rate of failure.
Above-described embodiment, is preferred embodiment of the present utility model, is not used for limiting the utility model practical range, therefore all equivalent variations of being done with content described in the utility model claim all should be included in the utility model claim scope.
