Abstract
The utility model discloses a novel main bus of a capacitance insulating switch cabinet, which comprises a current conductor and a capacitance insulator, wherein the current conductor is wrapped by the capacitance insulator, and the current conductor is in a tube shape. Flat connection portions formed by pressing are arranged on the current conductor at intervals, and the flat connection portions are not provided with the capacitance insulator. Each flat connection portion is provided with two parallel faces, a gap is arranged between the two parallel faces, and parallel faces of a plurality of connection portions are parallel to each other. Two ends of a capacitive screen arranged inside the capacitance insulator are gradually shortened according to a reasonable difference from inside to outside, an innermost screen of the capacitive screen and the current conductor are equipotential, and an outermost screen of the capacitive screen is connected with a ground lead and connected with a ground potential through a ground lead. Due to the fact that the current conductor is tube-shaped, current skin effects are effectively reduced, current carrying capacity is increased, and further more, the main bus can be supported by fixed holding tools and the supporting structure is simple.
