Monitoring device for transformer station foundation settlement monitoring

Abstract

The invention discloses a monitoring device for transformer station foundation settlement monitoring, and aims to provide the monitoring device for transformer station foundation settlement monitoringthat is characterized by easy installation of grounding wire, reliable connection, and convenient carrying operation in the process of resettlement to a next measurement station at the end of operation at a previous measurement station. The monitoring device comprises an invar leveling staff and a grounding device, the grounding device consists of an installation sliding sleeve sleeved on the invar leveling staff, an installation sliding sleeve electric connection piece that is disposed on the inner side of the installation sliding sleeve and is electrically connected to the invar leveling staff, a fastening bolt that is disposed on the installation sliding sleeve and is used for fastening the installation sliding sleeve on the invar leveling staff, and a reel rotatably disposed on the installation sliding sleeve and a grounding wire reeled on the reel.

Description

technical field [0001] The invention relates to a monitoring device, in particular to a monitoring device applied to substation foundation settlement monitoring. Background technique [0002] After the substation is completed and put into operation, the foundation of the substation will have different degrees of settlement, which poses a major threat to the safe operation of the substation, especially for the GIS equipment of the substation. Sulfur leakage will cause very serious consequences. In order to ensure the stable operation of the substation, the foundation settlement of the substation must be closely monitored, and the foundation settlement monitoring work needs to be carried out regularly. [0003] At present, precise geometric leveling technology is the main means of substation foundation settlement monitoring. Through monitoring, we can: (1) timely and quantitatively discover the unstable settlement of the foundation; (2) timely discover the influence of uneven...

AI Technical Summary

Problems solved by technology

[0004] The instruments and equipment used in the application of precision geometric leveling technology to substation foundation settlement monitoring mainly include precision levels and leveling rods. In order to ensure monitoring accuracy, the leveling rods are Invar leveling rods, which are usually installed in the center of a wooden frame. Invar alloy tape ruler, because the Invar alloy tape ruler is a metal conductive tape ruler, a grounding wire must be installed on the Invar leveling rod when working in the electrified area of ​​the substation; this makes it necessary to install a grounding wire during each measurement process, and During the measurement process, every time the operation of a measuring station is completed and transferred to the next measuring station, the grounding wire must be disassembled and transported to the next measuring station. This is not only inconvenient to install the grounding wire, but also the current grounding wire is long and messy. It is inconvenient to carry, and often requires the cooperation of multiple people, which brings a lot of inconvenience to the settlement monitoring work
