Electric power substation 110kV high framework isolation switch overhaul rack

Abstract

The invention relates to an electric power substation 110kV high framework isolation switch overhaul rack. The electric power substation 110kV high framework isolation switch overhaul rack comprises an overhaul rack base, a safe hanging rod (6) and a suspension ring (7), wherein the suspension ring (7) is mounted at a top end of the safe hanging rod (6), the overhaul rack base comprises an upper clamping board (1), a lower clamping board (2) and a square barrel (3), the upper clamping board (1) is fixed with the lower clamping board (2) through first fixing bolts (4), the upper clamping board (1) and the lower clamping board (2) are connected at a side face of the square barrel (3), the safe hanging rod (6) is inserted in the square barrel (3), a second fixing bolt (5) penetrates through the square barrel (3) and the safe hanging rod (6), and thereby the safe hanging rod (6) and the overhaul rack base are fixed. According to the electric power substation 110kV high framework isolation switch overhaul rack, the overhaul rack base employs a detachable structure and is connected with the safe hanging rod employing the square barrel, the square barrel is simple to manufacture, and the detachable structure is convenient to use.

Description

technical field [0001] The invention relates to a maintenance frame for a 110kV high-frame isolating switch in a substation, belonging to the field of electric equipment. Background technique [0002] In 2006, Wuxi Power Supply Company of Jiangsu Electric Power Company designed and manufactured the first batch of switch knife maintenance racks by Dai Honggen and Wu Zuoquan. The base support of the upper switch knife is mostly composed of angle iron, which is not suitable for installing this type of maintenance frame on it; currently, no one pays much attention to the design research of the switch knife maintenance frame whose base support of the switch knife is not composed of channel steel. [0003] There are following deficiencies in the overhaul stand in the prior art: [0004] (1) The existing switch knife maintenance frame used in the substation maintenance unit is mainly designed according to the characteristics of the channel steel base bracket of the switch knife, a...
