The 750kV hanging tube bus outgoing/incoming structure comprises the hanging tube bus, the incoming lead and the outgoing lead, wherein the hanging tube bus is horizontally arranged, the incoming lead and the outgoing lead are respectively connected with the hanging tube bus, and the incoming lead and the outgoing lead form the included angle of 90 DEG.
Description
Technical field
The utility model relates to extra-high voltage electric power transmission field, especially relates to a kind of 750kV suspension tubular busbar line structure.
Background technology
The main transformer inlet wire of 750kV transformer station or side outlet adopt underframe to cross the mode into string, and wherein the wire of main transformer inlet wire or side outlet will be connected with isolating switch in string.Because the layout of 750kV transformer station is comparatively compact, the wire of main transformer inlet wire often with string in isolating switch not point-blank, simultaneously because sectional area of wire is larger, hardness is very high, be subject to relatively, the alternate restriction with electrical distance, so wire is directly connected comparatively difficulty with isolating switch.
In engineering in the past, having used suspention wire to carry out twice 90 ° of turnings draws and connects, or adopt and on ground, to install twice 90 ° of turnings of post insulator inlet wire additional and draw and connect, these two kinds of modes are owing to adopting large-section lead, wire hardness is not easy to more greatly turn to draw connect, and difficulty of construction is very large, and this mode not only increases the difficulty of site operation, wiring is irregular, attractive in appearance, is also unfavorable for substation operation maintenance.
Utility model content
Technical problem to be solved in the utility model is: the problem existing for prior art, provides a kind of 750kV suspension tubular busbar line structure.Specifically by inlet wire wire, outlet wire, be connected with suspension tubular busbar, and inlet wire wire, outlet wire angle be that the mode of 90 ° designs, reduce wire and draw the difficulty connecing, be conducive to installation, operation, the maintenance of equipment.
The technical solution adopted in the utility model is as follows:
A 750kV suspension tubular busbar line structure, is characterized in that comprising suspension tubular busbar, inlet wire wire, outlet wire; Described suspension tubular busbar horizontal positioned, described inlet wire wire, outlet wire connect gold utensil and are connected by managing female T with suspension tubular busbar respectively, and inlet wire wire, outlet wire angle are 90 °.
Described inlet wire wire, outlet wire are double bundle conductor or 4 bundle conductors.
Described inlet wire wire is during perpendicular to horizontal plane, and outlet wire is parallel with horizontal plane; When inlet wire wire is parallel with horizontal plane, outlet wire is perpendicular to horizontal plane.
750kV suspension tubular busbar line structure also comprises the first grading ring, second grading ring, and described suspension tubular busbar is connected with the first grading ring, the second grading ring.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
The described mode of carrying out line turning with suspension tubular busbar, turning connects gold utensil with the female T of pipe and draws and connect, and designed grading ring, reduced the surface electric field intensity of wire, gold utensil, prevent the generation of corona noise, wiring is attractive in appearance, convenient, is conducive to optimize wiring and the layout of transformer station, has good economic benefit.Through optimization, the mode that adopts suspension tubular busbar to carry out line turning.
The utility model suspension tubular busbar line structure is through optimizing rear overhang swing pipe bus, adopt pipe bus-bar T-connecting gold utensil crimping lead wire mode to turn, the mode that it all adopts wire to turn than conventional inlet wire, outlet, or than ground, install the mode that post insulator is turned additional.Designed the first grading ring, the second grading ring simultaneously, reduced the surface electric field intensity of wire, gold utensil, prevented the generation of corona noise, wiring is attractive in appearance, convenient, has good economic benefit, for follow-up EHV transmission engineering has important reference and reference.
