The utility model discloses a new energy box transformer m type busbar structure, especially be applicable to large capacity wind power box type substation low voltage unit, it includes A phase copper bar, B phase copper bar, C phase copper bar, A phase hangs and connects cable row, B phase hangs and connects cable row, C phase hangs and connects cable row, horizontal insulator, vertical insulator, and each phase copper bar includes the export copper bar I of upper and lower settings, export copper bar II, export copper bar III, and export copper bar I, export copper bar II, export copper bar III are connected with insulator fixed beam through horizontal insulator, wherein export copper bar I, export copper bar II, export copper bar III are arranged at interval after the lower end of bending, and constitute m shape from the side angle, and the arrangement of this kind of structure can greatly reduce the use amount of copper bar and auxiliary material, reduce the fixed point required by busbar etc. while reducing product cost, save the installation space, and reduce the cost.

The utility model relates to the field of voltage withstanding tests, in particular to a GIS bent neck voltage withstanding tool. The cable comprises a sleeve assembly, a bent neck assembly and a conductor. The sleeve assembly is obliquely distributed and comprises a conductive tube, a first grading ring, a sleeve sleeving the peripheral side of the conductive tube, two groups of connecting assemblies electrically connected to the top end and the bottom end of the conductive tube respectively, and a wiring terminal connected with the sleeve, the first grading ring and the connecting assembly at the top end of the conductive tube; the bent-neck assembly comprises a bent-tube-shaped bent-neck shell of which the top end is connected with the bottom end of the sleeve, an insulating assembly connected to the bottom end of the bent-neck shell, a voltage-sharing assembly connected to the insulating assembly, a bent-neck conductor of which the bottom end is connected to the upper part of the insulating assembly, and a first contact seat connected between the top end of the bent-neck conductor and the connecting assembly at the bottom end of the conductive tube. According to the utility model, the direction of the sleeve can be rotated on site, obstacles are avoided, resources and time are saved, and voltage withstanding work of the interval and the cable head can be realized by only replacing the conductor at the lower part.
