Problems solved by technology

Assembled GIS equipment has many equipment components, and the length of the tubular busbar is relatively large. Under the action of wind force or electromagnetic force of adjacent busbars, it is easy to cause natural vibration or resonance of the busbar, and the large vibration will cause its fastening structure to loosen and break. The insulation structure is damaged, the bus bar is deformed, and the fatigue of the soft connection causes some or all fractures
After a period of time when the vibrating busbar is sick, its infrastructure will settle to varying degrees, causing overall deformation of the GIS equipment, damage to the seal, and SF6 leakage, especially at the support of the GIS outlet casing

Embodiment Construction

[0020] GIS busbar equipment is a complete set of high-voltage electrical equipment composed of circuit breakers, disconnectors, grounding switches, quick grounding switches, SF6 bushings, busbars, voltage transformers, current transformers, lightning arresters, etc., through conductive connectors and other components of GIS Connected to meet different main wiring methods to collect, distribute and transmit electric energy. The conductors in the bus barrel are arranged in a triangle, and the disc insulator fixes the three-phase bus in a certain position through the conductors and contacts, and plays the role of ground insulation. The topology and installation structure of the bus equipment are as follows: Figure 1 to Figure 2 .

[0021] During the operation of the long busbar, if the basic components are not installed firmly, under the action of large wind force or the electromagnetic force of the adjacent busbar, it is easy to cause the self-vibration or resonance of the bus...

Abstract

The invention relates to a GIS bus vibration condition monitoring device and monitoring method. The device comprises vibration sensors arranged at preset measuring point positions and a monitoring terminal connected with the vibration sensors. The vibration sensors are used for detecting vibration data of the positions where the vibration sensors are located and sending the vibration data to the monitoring terminal. The monitoring terminal is used for intensively receiving the vibration data, comparing the vibration data with a preset threshold value, and performing early warning and remindingoperation when the vibration data exceeds the threshold value, and the preset measuring point positions comprise a topology measuring point and a structure measuring point. According to the invention, the abnormal vibration of a GIS bus in the operation process can be discovered in time by an operator; meanwhile, the collected vibration data can provide a basis for subsequent research and analysis, hidden dangers can be found as soon as possible, accidents are eliminated in the bud, the safe operation level of a system can be improved, and economic losses caused by the accidents can be reduced.

Description

technical field [0001] The invention relates to the technical field of gas insulated switchgear GIS, in particular to a GIS busbar vibration monitoring device and monitoring method. Background technique [0002] Gas insulated switchgear (GAS insulated SWITCHGEAR, referred to as GIS) is widely used in large electric power enterprises due to its safe and reliable operation, small footprint and no external environment influence. GIS equipment has fewer failures than separate open equipment, but once a failure occurs, the consequences are much more serious, not only the repair process is complicated, but also the repair time is long and the economic loss is large. [0003] Excessive busbar vibration is one of the faults of GIS equipment. Assembled GIS equipment has many equipment components, and the length of the tubular busbar is relatively large. Under the action of wind force or electromagnetic force of adjacent busbars, it is easy to cause natural vibration or resonance of ...
