An operating platform for installing grounding wires on the high-voltage side of transformers

Abstract

The invention discloses an operating platform for hanging a ground wire on the high voltage side of a transformer. The operating platform comprises a galvanized steel sheet and a steel sheet support. The galvanized steel sheet is transversely arranged and is clamped between two corresponding cable supports. A plurality of cross braces are arranged below each cable support in sequence from top to bottom. The steel sheet support is arranged below the galvanized steel sheet and located between two corresponding cable supports. The steel sheet support comprises galvanized angle steel and two head plates. The galvanized angle steel is arranged on the lower surface of the galvanized steel sheet, the top ends of the two head plates are welded to the front end and the rear end of the galvanized angle steel correspondingly and respectively, and each head plate is fixed to the corresponding cable support through a bolt. The operating platform is simple in structure, quite convenient to construct, safe and firm and utilizes the existing cable supports.

Description

technical field [0001] The invention relates to an operation platform for installing and hanging grounding wires on the high-voltage side of a transformer. Background technique [0002] At present, 110 kV indoor substations are becoming more and more popular. The distance between the bushing on the high voltage side of the 110 kV transformer and the ground is very high, and the distance between the corresponding 110 kV incoming cable bushing and the ground is also very high, usually 7-8 meters. . In the 110kv main transformer room, the height from the bottom of the 110kv incoming cable head porcelain bottle to the ground is about 6 meters. In this way, when the transformer needs to be overhauled, it will be very difficult to hang the ground wire on the 110kV side of the main transformer (near the cable head) , the operator needs to climb from the cable support to the cable porcelain vase, but there is no platform for standing on the base of the cable vase, and it is very ea...

AI Technical Summary

Problems solved by technology

In the 110kv main transformer room, the height from the bottom of the 110kv incoming cable head porcelain bottle to the ground is about 6 meters. In this way, when the transformer needs to be overhauled, it will be very difficult to hang the ground wire on the 110kV side of the main transformer (by the cable head) , the operator needs to climb from the cable support to the cable vase, but there is no platform at the base of the cable vase, and it is very easy to fall from a high altitude when the ground wire is hung

In addition, when the 110kV high-voltage side cable head needs construction or maintenance, similar problems will also arise
