Split lead T-connection converting armor clamp and wire clamp body thereof

Abstract

The invention discloses a split lead T-connection converting armor clamp and a wire clamp body thereof. A bus clamp block of the wire clamp body is provided with a support arm portion at the end portion of a bus duct, the support arm portion extends along the length direction of the bus duct, the support arm portion is fixed or integrated to a branch clamp block, a branch duct is arranged along the length direction of the bus duct in a spatially interlaced manner, and the two ends of the branch duct are respectively placed at the two sides of the width direction of the bus duct. After the wire clamp body is mounted on a rod-shaped terminal, a split flexible lead is arranged along the length direction of the rod-shaped terminal in the spatially interlaced manner due to guide of the relative positions of the branch duct and the bus duct, and the split flexible lead extends or penetrates from one axial side of the rod-shaped terminal to the other axial side of the rod-shaped terminal; and thus, the wire clamp body is prevented from axial rotation around the rod-shaped terminal due to the gravity effect of the split flexible lead and the branch clamp block on the moment of the rod-shaped terminal, and it is ensured that the split flexible lead is reliably connected to the rod-shaped terminal.

Description

technical field [0001] The invention relates to a split wire T-connection conversion fitting and a wire clip body thereof. Background technique [0002] At present, with the use of ±800kV UHV DC converter station fittings in domestic DC converter stations in recent years, the requirements for the use of converter station fittings in the construction of UHVDC converter stations have also increased. In the conversion connection between the bar terminal and the four-split flexible conductor in the DC converter station, the bar terminal can be connected with the four-split soft conductor through the fitting device, and the bar terminal can play a role in the fitting device due to its greater rigidity. The role of support, the existing T-connection conversion fittings between the rod terminal and the four-split soft wire mostly adopt a kind of "pipe bus split wire "Clamp hardware" includes two clamp bodies that can be buckled up and down. The two ends of the clamp body are respe...

Problems solved by technology

However, if this T-connection method is applied between the bar terminal and the four-split soft conductor, because the bar terminal is not only a conductive contact, but also acts as a supporting structure in the T-junction structure, so that all four-split soft conductors are biased. In the case of setting, the four-split soft wire and the branch line clamp block will apply torque to the tube busbar clamp through its own weight, so that the tube busbar clamp has a tendency to rotate relative to the rod terminal, which will not only affect the pipe busbar clamp on the tube The installation reliability on the busbar, and the rotation of the pipe busbar hoop on the outer circumference of the pipe busbar will scratch the contact surface of the pipe busbar and the pipe busbar hoop, making the conductive connection between the pipe busbar and the pipe busbar hoop also unstable Therefore, the existing T-connection conversion fittings have the problems of poor reliability and unstable conductive contact in the connection between the rod terminal and the four-split flexible wire
