Background
At present, a bus adopts a common box arrangement mode, the structure of a three-phase common box bus is shown in fig. 1, the bus comprises a bus barrel 01 and three-phase common box bus conductors, the three-phase common box bus conductors are three-phase conducting rods 02, two ends of the bus barrel are respectively connected with supporting insulators 03, the bus barrel between two adjacent supporting insulators 03 is of a two-section structure, the bus barrel comprises a first barrel section and a second barrel section which are separated, the two barrel sections are in butt joint through flanges, the two supporting insulators 03 are respectively a first supporting insulator and a second supporting insulator which are connected with the first barrel section and the second barrel section, an insert conductor is arranged on the supporting insulator 03, each insert conductor is respectively connected with a contact seat 04, the contact seats 04 are in conductive connection with a conducting rod, two ends of the conducting rod 02 are respectively connected with the contact seats 04 on the supporting insulators 03 at two ends of the bus barrel 01, the conducting rod 02 is longer than any barrel section of the bus barrel 01, and three pull-out openings 05 distributed along the circumferential direction are respectively arranged at the positions of the end parts of the bus barrel 01, which are close to the two supporting insulators 03; when the bus is assembled, the first cylinder section and the first supporting insulator are connected, when the conducting rod is assembled with the first cylinder section and the first supporting insulator, the center of gravity position of the conducting rod can be slightly adjusted by hoisting the middle part of the conducting rod, the conducting rod stretches into the first cylinder section, when the conducting rod is connected with a first contact seat on the first supporting insulator, auxiliary assembly can be carried out at three small openings of the end part of the bus cylinder by manpower, after the conducting rod is assembled with the first cylinder section and the first supporting insulator, as shown in fig. 2 and 3, the supporting plate 06 can be used for supporting the three-phase conducting rod 02 outside the first cylinder section, namely, the part of the three-phase conducting rod 02 exposed out of the first cylinder section is supported by fixing the supporting plate 06 on an end flange of the first cylinder section, when the distance between the first cylinder section and the second cylinder section is about 50mm, the two cylinder sections can be disassembled, and the auxiliary assembly of the bus is carried out at the three small openings of the end part by manpower when the conducting rod is connected with the second contact seat on the second supporting insulator; when the common-box bus structure is assembled, the assembly method is mature, and the assembly tool is simple.
However, the above-mentioned common box busbar structure, though the assembly mode is ripe and simple, but to its structure itself, because the busbar barrel divide into independent two sections, the butt joint end of two sections barrels need to set up the flange, and the other end of each barrel section all needs to set up three respectively and pulls out the mouth, whole busbar barrel needs to set up six and pulls out mouthful, and every pulls out mouthful all needs to have the configuration seal cover plate, thereby make busbar structure complicacy, the manufacturing cost of busbar product is higher, in practical application, because common box busbar quantity is very big, how to reduce cost is very important to enterprise market competition and operation profit.
Based on the problem of higher cost of the sectional bus, the existing bus barrel between two adjacent supporting insulators is made into an integrated structure, and the bus structure omits the arrangement of two butt flanges and three pull openings at one end of the bus barrel, but the other end of the bus barrel still needs to be provided with three pull openings so as to be convenient for assembly; for the setting of pulling out the mouth, not only need open the hole on the generating line barrel, still need to weld the switching nipple joint on the hole edge after the trompil to utilize the switching nipple joint to form planar terminal surface, still need to pull out mouthful department installation seal cover plate in order to realize the sealing to pulling out the mouth, need set up three and pull out mouthful and need three seal cover plate on the whole, the generating line product manufacturing cost of structure still is higher like this.
Therefore, there is a design idea finally, only one pull-out opening is arranged at one end of the bus barrel, the size of the pull-out opening is not increased, the bus structure is shown in fig. 4, only one bus barrel 001 is arranged between two adjacent supporting insulators, one end of the conducting rod 002 is connected with a first contact seat 041 on a first supporting insulator 031, the other end is connected with a second contact seat 042 on a second supporting insulator 032, the bus barrel 001 is in an integrated structure, and only one pull-out opening 005 is arranged at one end of the bus barrel 001; the bus with the structure can greatly reduce the manufacturing cost of the bus with the common box.
However, for the bus of the structure, when the second contact seat close to the pull-out position is in butt joint with the three-phase bus conductor, no good assembly mode exists at present, if the assembly is simply carried out manually, two arms are required to extend into the pull-out position to support the three conducting rods, the assembly is limited by the assembly position of the three-phase conducting rods, and the assembly is very inconvenient due to factors such as the fact that the conducting rods are long and heavy (the length of the conducting rods is close to 6 m). Therefore, how to realize the convenience of assembling the bus of the single-pull-out integrated bus barrel is a key problem encountered at present under the condition of ensuring the lowest cost.
