Embodiment Construction

[0019] Examples of connecting fittings for the valve hall of the converter station in the present invention figure 1 and figure 2 As shown: the connecting hardware for the valve hall of the converter station includes two pipe busbars 1 arranged perpendicular to each other, that is, the angle between the length extension directions of the two pipe busbars 1 is 90 degrees. There are 10 bent flexible wires connected between the two pipe busbars 1, and the center line of each flexible wire on the section perpendicular to the extension direction of each flexible wire at the bend of the flexible wires is a curve 5, which is distributed on two sides of the curve 5. The flexible conductor at the end is called the end flexible conductor, and the flexible conductor distributed between the end flexible conductors is called the middle flexible conductor, and the diameter of the end flexible conductor is larger than that of the middle flexible conductor. The ten flexible wires are respec...

Abstract

The invention relates to a connection fitting for a converter station valve hall. The connection fitting for the converter station valve hall comprises two tubular bus bars which are arranged obliquely or vertically, wherein more than two bent flexible conductors are connected between the two tubular bus bars; the connecting line of the centers of the flexible conductors on the sections, vertical to the extension directions of the flexible conductors, of the bent parts of the flexible conductors is a curve; the flexible conductors distributed at two ends of the curve are called end-part flexible conductors; the flexible conductors distributed between the end-part flexible conductors are called middle flexible conductors; and the diameters of the end-part flexible conductors are greater than those of the middle flexible conductors. According to the skin effect of currents, the currents of the end-part flexible conductors are greater than those of the middle flexible conductors, so that the flexible conductors with relatively large diameters are selected as the end-part flexible conductors; the flexible conductors with relatively small diameters are selected as the middle flexible conductors; the temperature rises of the end-part flexible conductors and the middle flexible conductors are uniform; and over-high temperature rises of the flexible conductors areprevented.

Description

technical field [0001] The invention relates to the field of connecting fittings, in particular to a connecting fitting for a valve hall of a converter station. Background technique [0002] The valve hall of the converter station of the UHV DC transmission system is a closed space, in which there are converter valves, transformer bushings, wall bushings and other equipment. Different equipment needs to be connected by pipe bus to form a transmission circuit. Realize the conversion of AC and DC. In some occasions, pipe busbars are required to realize turning. At this time, two pipe busbars that are inclined or perpendicular to each other are usually connected after being bent by a plurality of flexible wires. [0003] For example, the authorized announcement number is CN201656381U, and the Chinese patent titled pipe busbar corner connection fittings discloses a kind of pipe busbar corner connection fittings. The pipe busbar corner connection fittings include two mutually i...
