Abstract

The invention relates to a converter high-voltage-end lightning arrester connecting fitting for a 800kV valve hall. The converter high-voltage-end lightning arrester connecting fitting for the 800kV valve hall comprises an anticorona ball, a tubular bus bar fixing fitting, a cardan joint suspension assembly, a lightning arrester connecting frame and two overcurrent copper wires, wherein the anticorona ball is a shell formed by connecting an upper hemisphere and a lower hemisphere, the shell is provided with a top opening, two side openings and suspension lugs, the tubular bus bar fixing fitting comprises a pair of U-shaped half sleeves, three connecting ends are arranged on the top of each U-shaped half sleeve at intervals, the connecting ends at the two ends of each U-shaped half sleeve are connected to the two corresponding suspension lugs of the four suspension lugs in the shell, a threaded rod of an articulation link of the cardan joint suspension assembly is connected with the lightning arrester connecting frame, an articulation piece is arranged in the middle of the cardan joint suspension assembly, articulation holes are formed in the articulation piece, and are perpendicular to each other, and an articulation base on the lower portion of the cardan joint suspension assembly is connected with the tubular bus bar fixing fitting. After each overcurrent copper wire is bent to be of an arc shape, one end of each overcurrent copper wire is connected with the lightning arrester connecting frame, and the other end of each overcurrent copper wire is connected with one connecting end of the corresponding U-shaped half sleeve, so that a flexible overcurrent loop is formed. The converter high-voltage-end lightning arrester connecting fitting for the 800kV valve hall can be widely applied to converter high-voltage-end lightning arrester connecting fitting structures for the 800kV valve halls.

Description

technical field [0001] The invention relates to an electric power fitting, in particular to a connecting fitting for a high-voltage end surge arrester of a converter for an 800kV valve hall. Background technique [0002] At present, my country has become a major DC power transmission country with the most operating and under-construction DC projects, the largest capacity and the longest lines in the world. Valve hall fittings in DC converter stations can generally be divided into valve hall connecting fittings, anti-halo (ball), shielding half-rings and some transition fittings. With the increase of DC transmission voltage, valve hall fittings have increasingly become an indispensable part of the valve hall. The valve hall fittings of the converter station in our country are basically purchased from abroad, and the cost is relatively high. Considering that there are many ultra-high voltage and ultra-high voltage direct current transmission converter stations in my country'...
