Abstract
The present invention relates to a kind of electric power fittings, especially a split-structure anti-corona tubular busbar drainage clamp used in high-voltage substations. There are drainage terminals, which are fixedly connected to the hardware body by bolts, and are provided with a semi-circular cavity cavity metal fitting cover plate; the fitting body and the fitting cover plate are two, the drainage terminal is a cuboid, and the left and right sides of the cuboid drainage terminal are two. The end is provided with an anti-corona cylinder, and the two fitting bodies are located at the upper end of the anti-corona cylinder. The lower end under the anti-corona cylinder is provided with an anti-corona spheroid. It can effectively reduce the length of the contact surface along the axial direction of the tubular busbar, increase the compactness of the contact with the tube surface, and ensure the drainage of large currents; increase the corona initial voltage, reduce the electric field intensity, and reduce the corona damage occur.
Description
technical field [0001] The invention relates to a power fitting, in particular to a split-structure anti-corona-type tubular busbar drain clamp used in a high-voltage substation. Background technique [0002] In high-altitude areas, especially in ultra-high voltage substations of 330kV and above, there are more and more applications of tubular busbars. The connection between tubular busbars and equipment must use tubular busbar drainage clips. At present, the connection between the tubular busbar and the equipment adopts the integrated structure of the drainage clip. The shape of this type of clip is large, and the contact surface when it contacts with the tubular busbar is too long, which affects the compactness of the contact surface and causes the contact surface to contact. The coefficient is small, which affects the over-current capability and easily causes the clip to heat up. At the same time, in the connection of equipment leads of tubular busbars with voltage level...
