Replacement device used for disconnector spring

Abstract

The invention provides a replacement device used for a disconnector spring, relating to the technical field of electrical equipment. The replacement device comprises a disconnector rod, a spring and afixing ring, a first fixing seat, a second fixing seat and an adjusting component, wherein one end of the spring is in butt joint with one end of the disconnector rod, and the other end of the springis in butt joint with the fixing ring; the second fixing seat is in butt joint with the fixing ring, two ends of the adjusting component are respectively connected with the first fixing seat and thesecond fixing seat, the second fixing seat can move relative to the disconnector rod by the adjusting component, so as to compress or release the spring by the fixing ring, so that when the spring ofthe disconnector is replaced, elastic energy can be slowly released, and when the spring is mounted, the spring can be slowly compressed; the technical problems in the prior art that energy is easy torelease to hurt people, mounting and dismounting waste time, and risk exists when the disconnector spring is mounted and dismounted are solved; and the replacement device has the advantages of simplestructure, low manufacture cost, simple operation, improvement of working efficiency, reduction of working risk, and increasing of the productivity effect of social enterprises.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a replacement device for a knife switch spring. Background technique [0002] GW16-220 single-column vertical fracture isolating switch is a three-pole outdoor high-voltage electrical appliance for switching 220kV high-voltage lines under no-carrying conditions and electrically isolating the overhauled high-voltage busbars and other electrical equipment from live lines; this type of switch The brake has reliable performance, simple operation and good flow performance, and is unanimously welcomed by people in the same industry, but this knife switch also has some shortcomings. For example, during the long-term use of this type of knife switch, its internal balance, clamping The shortening of the spring stroke results in a smaller torque, which often leads to difficulties in opening and closing, and the pressure of the clamping contacts becomes smaller. Therefore, after ...
