Abstract
The utility model relates to a power equipment, especially to an equipotential sealing support type enclosed bus. Four support insulators (11) in an X-shaped mode are installed in sealed housings (2) by housing support structures (3); and the inner ends of the support insulators (11) are connected with the external peripheries of equipotential conductors (9) arranged at the center inside the sealed housings (2). Three-phase enclosed buses are fixed at a bus support seat (10) and are installed at and connected with a heavy-current testing transformer (7) by an integrated way by standard segment assembling units (1); conductor connection aluminum bars (5) are arranged at the right ends of the three-phase enclosed buses; and housing short-circuit connection aluminum bars (6) and housing short-circuit boards (4) are arranged at the two ends of the sealed housing (2) of the three-phase enclosed buses after connection. The equipotential sealing support type enclosed bus has the advantages of security and reliability, small size and installation space and material saving.
Description
Technical field
The utility model belongs to power device, particularly a kind of equipotential sealing brace type enclosed busbar.
Background technology
At present, the single-machine capacity of the generating set of the power equipment of China constantly increases, to the conductive section of enclosed busbar, require also more and more higher, simultaneously to electric property, insulation function, the indexs such as mechanical strength also propose requirements at the higher level, and existing generating set still adopts relatively more conservative large electric current enclosed busbar, this blockade line mother is bulky, take up room large, waste a large amount of nonferrous materialss, especially in hydroelectric project, in the limited situation of soil space and more inapplicable in the tunnel involving great expense simultaneously.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides that a kind of supporting structure is reasonable, volume is little, equipotential sealing brace type enclosed busbar applied widely.
The technical scheme that the utility model technical solution problem adopts is: equipotential sealing brace type enclosed busbar comprises can, enclosure support structure, envelope star conductor supporting structure, cranking test transformer, standard paragraphs assembling, be characterized in by enclosure support structure, becoming positive X-shaped that four supporting insulators are housed in can, evenly be connected with the equipotential conductor excircle of center in can supporting insulator is inner, the enclosed busbar of three-phase is fixed on bus supporting seat, and with standard paragraphs assembling integral installation connection cranking test transformer, on the right-hand member head of the enclosed busbar of three-phase, establish conductor and connect aluminium row, on the can two ends of the three-phase enclosed busbar after connection, establish shell short circuit and connect aluminium row and shell short board.
The beneficial effects of the utility model are: equipotential sealing brace type enclosed busbar adopts positive X-type four-point supporting, be suitable on the enclosed busbar of heavy-duty generator group, make enclosed busbar insulator stress equalization, be difficult for making hydrogen leak to bus, the blast of having avoided the sparkover that equipotential does not cause and cause, safe and reliable, volume is little, saves installing space and material.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, with embodiment, illustrate.
Fig. 1 is equipotential sealing brace type enclosed busbar three-phase installation diagram.
Fig. 2 is the local installation diagram of overlooking of Fig. 1.
Fig. 3 is the A-A cutaway view of Fig. 1.
In figure, the assembling of 1-standard paragraphs; 2-can; 3-enclosure support structure; 4-shell short board; 5-conductor connects aluminium row; The short circuit of 6-shell connects aluminium row; 7-cranking test transformer; 8-envelope star conductor supporting structure; 9-equipotential conductor; 10-bus supporting seat; 11-supporting insulator.
Embodiment
Embodiment, with reference to accompanying drawing 1 ~ 3, the can 2 of equipotential sealing brace type enclosed busbar is interior is equipped with four supporting insulators 11 with 3 one-tenth positive X-shapeds of enclosure support structure, the excircle of the even equipotential conductor 9 with can 2 interior centers in the inner of supporting insulator 11 is connected, the enclosed busbar of three-phase is fixing female on bus supporting seat 10, and installs and connect on cranking test transformer 7 with standard paragraphs assembling 1.On the right-hand member head of the enclosed busbar of three-phase, establish conductor and connect aluminium row 5, on can 2 two ends of the three-phase enclosed busbar after connection, establish shell short circuit and connect aluminium row 6 and shell short board 4.The enclosed busbar of three-phase is fixed on wall by shell supporting structure 3 and the envelope star conductor supporting structure 8 of establishing on can 2.
The operation principle of equipotential sealing brace type enclosed busbar is: enclosed busbar adopts positive X-type four-point supporting formula, while guaranteeing its steady operation, bus is easy to from main stress, and freely from alignment, physics is neutral freely to coincide with how much neutral points, make supporting insulator 11 stress equalizations, the blast of avoiding sparkover that equipotential does not draw to cause.
