Abstract
The invention discloses a high-voltage enclosed bus comprising a housing and three busbars fixedly arranged in the housing in a triangular shape. Insulated sheaths are fixedly disposed on the peripheries of the busbars. The busbars are hollow structures. The center of each busbar is provided with a through hole extending along a central line. A support is disposed in each through hole and is an integral structure. The support comprises a first supporting plate and a second supporting plate which are connected through a connecting plate to form an H-shaped structure. Both ends of the first supporting plate and both ends of the second supporting plate support the wall of the through hole. Since the busbars are hollow structures and the supports are disposed in the through holes, ventilation channels are formed in the busbars. As a result, heat is easy to dissipate, light weight is achieved, and material is saved. Further, a problem is solved that poor heat dissipation causes high temperature and limited capacity.
Description
Technical field
The present invention relates to a kind of enclosed busbar, particularly a kind of high pressure enclosed busbar, belongs to the technical field of transmission facility.
Background technology
Along with the develop rapidly of electric power system, circuit adopts the power transmission and distribution mode of power cable to get more and more, power cable line increase the sharply increase causing system capacitance electric current, under the operational mode of isolated neutral, when single-phase earthing, because capacitance current is excessive, electric arc can not extinguish, and the overvoltage caused by intermittence arc grounding can bring serious threat to the safe operation of the insulation of equipment and electrical network.Modern electric line has overhead power line and power cable line two kinds of modes substantially, along with the develop rapidly of China's economy, the modernization of city and national defense construction, intensive at urban population, transport hub and electrical network cross-country, for security consideration and the restriction by ground location, do not allow erection shaft tower and overhead transmission line, also having in some severe contamination districts or national defense and military engineering is the power transmission and distribution mode avoiding the places, region such as exposure all to need to adopt power cable line, for 10KV system, the capacitance current of 1km power cable line is approximately 30 times of overhead power line, a large amount of employings of power cable certainly will cause the sharply increase of system capacity current, what China 6-66KV electrical network adopted is isolated neutral system, mustn't trip when there is one-way earth fault, system can continue operation 2 hours, the electric arc that excessive capacity current makes ground short circuit cause can not extinguish, overvoltage caused by intermittence arc grounding brings serious threat to the safe operation of the insulation of equipment and electrical network.
In order to solve the problems of the technologies described above, Chinese patent literature discloses a kind of high pressure enclosed busbar, the patent No. is: 201120075889.1, which disclose a kind of segmented energy-saving environment-friendly high-pressure enclosed busbar, comprise shell, three busbars, three described busbars are evenly fixedly installed in described shell, described busbar periphery is fixed with insulating sleeve respectively, described insulating sleeve periphery is fixed with corresponding electro-magnetic screen layer, described electro-magnetic screen layer adopts the mode disconnecting closed-loop path to be fixedly laid in described insulating sleeve periphery, because described insulating sleeve periphery is fixed with corresponding electro-magnetic screen layer, described electro-magnetic screen layer adopts the mode disconnecting closed-loop path to be fixedly laid in described insulating sleeve periphery, not only can alleviate the electromagnetic pollution to surrounding environment, and, also can avoid producing circulation, improve the fail safe of bus, but this patent busbar is solid construction, the coated electro-magnetic screen layer in periphery has considerable influence to its heat radiation, thus, greatly reduce the radiating effect of this bus.
Summary of the invention
Technical problem to be solved by this invention is the shortcoming for prior art, a kind of high pressure enclosed busbar is provided, the high pressure enclosed busbar of this structure not only can alleviate the electromagnetic pollution to surrounding environment greatly, and perfect heat-dissipating, thus ensure that the insulation of equipment and the safety in operation of electrical network.
In order to solve the problems of the technologies described above, a kind of high pressure enclosed busbar of the present invention, comprise shell, three busbars, three described busbars are fixedly installed in described shell in " product " font, described busbar periphery is fixed with insulating sleeve respectively, wherein, described busbar is hollow core structures, the center position of described busbar is provided with the through hole of centrally line extension, support is provided with in described through hole, described support is overall structure, described support comprises the first support plate, second support plate, described first support plate and described second support plate connect into " work " type structure by connecting plate, the two ends of described first support plate and described second support plate are supported on the hole wall of described through hole respectively, described first support plate is identical with described second plate structure, and described first support plate is the arc that aluminium alloy machined surface becomes.
Above-mentioned a kind of high pressure enclosed busbar, wherein, described busbar cross section is rounded.
Above-mentioned a kind of high pressure enclosed busbar, wherein, described connecting plate is the plate that aluminium alloy machined surface becomes.
The present invention can realize following beneficial effect:
Because described busbar is hollow core structures in the present invention, the center position of described busbar is provided with the through hole of centrally line extension, support is provided with in described through hole, described support is overall structure, described support comprises the first support plate, the second support plate, described first support plate and described second support plate connect into " work " type structure by connecting plate, and the two ends of described first support plate and described second support plate are supported on the hole wall of described through hole respectively; Described first support plate is identical with described second plate structure, and described first support plate is the arc that aluminium alloy machined surface becomes, and forms air duct, be not only easy to heat radiation in busbar inside, and lightweight, saves material; And solve due to heat dispersion difference and cause temperature high, make the problem of capacity constraint; Thus substantially increase female transmission power.
