Abstract
The utility model provides a special flexibility bridge connector of a wind power bus duct, comprising a metal bellows and a flexible conductor, two ends of the metal bellows and the flexible conductor are respectively connected with the corresponding bus duct shells, the flexible conductor is arranged in the metal bellows, two ends of the flexible conductor are fixedly connected with a bus bar of the corresponding bus duct respectively; an isolation distance piece is arranged between the adjacent flexible conductors, two ends of the isolation distance piece are fixedly connected with the bus bar of the e corresponding bus duct respectively; in the utility model, by utilizing the characteristics that the bellows can be extruded and the flexible conductor can properly solve the position error between the two sections of the bus ducts when in installation, the connected bus ducts realize multidirectional adjustment, and the special flexibility bridge connector can adsorb the vibration caused by the working of the bus duct and the displacement caused by thermal expansion, so as to reduce the effect of the vibration and thermal expansion on the bus bar of the bus duct and the shell after the bus duct is electrified and ensure the performances of a whole bus duct system.
Description
Technical field
The utility model relates to a kind of bus duct flexible bridge, and the special-purpose flexible bridge of particularly a kind of wind-powered electricity generation bus duct belongs to the technical field of bus duct accessory.
Background technology
Bus duct system is an efficient power distribution equipment of carrying electric current.Along with emerging in large numbers of modernization project facility and equipment, the power consumption of all trades and professions is fast to be increased, the appearance in especially numerous skyscrapers and large-sized workshop workshop, can not meet the demands in the now big electric current conveying system of traditional cable as transmission pressure, the parallel connection of multiway cable is used to on-the-spot installation connection and has been brought inconvenience.Bus duct arises at the historic moment as a kind of novel distribution lead, compares with traditional cable, demonstrates fully its superiority when big electric current is carried.Particularly in wind-powered electricity generation, obtained using widely.
The connector of prior art median generatrix groove adopts fixed method of attachment mostly, adopts fixing means to connect, between the adjacent bus duct for being rigidly connected, therefore, can't improve bus duct energising after, the displacement that the vibrations of conductor and thermal expansion produce is used bolt so need often maintenance to connect.And two joint bus ducts connect and can only be used for equidirectionally, and angle can't realize that two ends bus bus duct different angles freely change.In addition, because the particularity of wind-powered electricity generation industry, in the use, when the vertical bus groove was connected with the horizontal bus groove, the vertical bus groove was swung along with rocking of wind tower, the long-time use, tie point between the two joint bus ducts is damaged, therefore, reduce the useful life of bus duct, and increased the maintenance cost of wind-powered electricity generation.
The utility model content
Technical problem to be solved in the utility model provides the special-purpose flexible bridge of a kind of wind-powered electricity generation bus duct simple in structure and with low cost, and the bus duct bridger of this structure has solved adjacent bus duct can't carry out the problem that different angles are freely adjusted.
In order to solve the problems of the technologies described above, the special-purpose flexible bridge of a kind of wind-powered electricity generation bus duct of the utility model, comprise metal bellows, soft conductor that two ends link to each other with the respective bus bars slot shell respectively, described soft conductor is arranged in the described bellows, fixedlys connected with the busbar of respective bus bars groove respectively and be integral in the two ends of described soft conductor; Being equipped with an insulating spacer between the adjacent described soft conductor, fixedlys connected with the busbar of respective bus bars groove respectively in described insulating spacer two ends.
The special-purpose flexible bridge of above-mentioned a kind of wind-powered electricity generation bus duct, wherein, described metal bellows is a circle corrugated pipe.
The special-purpose flexible bridge of above-mentioned a kind of wind-powered electricity generation bus duct, wherein, described metal bellows two ends are respectively equipped with a jockey, described jockey comprises the gusset that links to each other with bus groove case, the flanged plate that is fixedly installed on the wavy metal pipe end, and described gusset is connected by securing member with described flanged plate.Adopt the bus duct flexible bridge of this structure,, make the connection of metal bellows bus duct more firm, convenient owing to metal bellows is linked to each other with bus duct by gusset and flanged plate.
Adopt the special-purpose flexible bridge of wind-powered electricity generation bus duct of said structure, because the bus duct flexible bridge comprises metal bellows and soft conductor, during the connection bus groove, utilize the squeezable characteristic of bellows and the conductor that is flexible coupling can suitably solve the characteristics of the error of the position between the two joint bus ducts when installing, make the bus duct that is connected realize the adjustment of multi-faceted trend, and the displacement that the vibrations that produce when bus duct worked and thermal expansion produce absorbs, thereby reduced bus duct energising back vibrations and thermal expansion influence, guaranteed the performance of integral bus bar tank systems bus duct busbar and shell; And avoided because of the bus duct swing makes the damage of bus duct coupling part, thereby prolonged the useful life of bus duct; In addition, because metal bellows is a circle corrugated pipe, make the metal bellows shock absorption stronger.
