Auxiliary replacement tool for static contacts of vertical telescopic disconnector

Abstract

The invention relates to the technical field of isolating switch replacing tools, and discloses an auxiliary replacing tool for a static contact of a vertical telescopic isolating switch. The auxiliary replacing tool comprises a support frame, a lifting ring and support clamps, wherein the lifting ring is fixedly installed in the middle of the top surface of the support frame, the support clamps are fixedly installed on the left and right sides corresponding to the lifting ring on the top surface of the support frame respectively, the support clamps are U-shaped, and a bottom support component capable of pressing against the top of a static contact rod is arranged at the bottom of the support frame. According to the auxiliary replacing tool, the bottom support component and the support cards can support a cross aluminum plate and the static contact rod, so that a worker can conveniently detach or install a T-shaped wire clamp; by adopting the auxiliary replacing tool for detaching or installing the static contact of the isolating switch, the operation is simple and convenient, time and labor are saved, the working efficiency is high, the labor cost can be effectively reduced, the safety factor can be improved, disposable equipment can be effectively prevented from being damaged in detachment and installation, and then the power supply reliability is improved.

Description

Technical field [0001] The invention relates to the technical field of an isolating switch replacement tool, and is an auxiliary replacement tool for the static contact of a vertical telescopic isolating switch. Background technique [0002] In recent years, as the operating life of the substation under its jurisdiction has increased, the primary equipment in the station has been aging for years, the electricity load has increased year after year, and the joints have frequent heating failures, which seriously affects the safe and stable operation of the equipment. The heating at the static contact fixture and busbar of 220kV vertical telescopic isolating switch is one of the common heating parts. In the process of heating treatment, it is often necessary to remove it from the busbar. The static contact usually includes a T-shaped clamp, a cross arm aluminum plate, a steel core aluminum stranded wire and a static contact rod. Because the cross arm aluminum plate and the static con...
