Online monitoring system for GIS busbar barrel

Abstract

The invention relates to an online monitoring system for a GIS busbar barrel. The online monitoring system comprises a monitoring terminal arranged on the barrel and a data processing unit connected with the monitoring terminal, wherein the monitoring terminal comprises a pull rod resistance displacement rule used for detecting the axial displacement of a barrel wall relative to a support, a stay cord displacement sensor used for detecting the displacement of the barrel relative to the ground, and a three-axis acceleration sensor used for detecting the axial and radial warping degrees of the barrel relative to a horizontal plane. By adopting the monitoring system, real-time monitoring can be realized, routing inspection work of workers is reduced, and the labor cost is reduced. Meanwhile, the operation safety of a busbar is improved, accidents, such as cracking of a busbar support, can be effectively prevented, and safety hazards and economic loss caused by bad breakdown repair can be avoided. The system is particularly applied to northwestern districts with a high diurnal temperature difference, high altitude regions, tundra regions and southern geological sedimentation districts.

Description

technical field [0001] The invention relates to an on-line monitoring system for a GIS busbar barrel, belonging to the field of high-voltage switchgear and high-voltage electrical appliance manufacturing. Background technique [0002] As the transmission line equipment of the ultra-high voltage power grid, the GIS bus barrel is the basic guarantee for the safe operation of the power grid. However, in my country’s Qinghai and Tibet regions, due to the unique climate and address conditions, the structure of the GIS busbar barrel is easily affected by factors such as sunshine, cooling, and annual temperature changes, resulting in temperature difference effects that lead to deformation and distortion of the busbar. Frequent cracking and sinking of GIS equipment foundations in areas with large altitude temperature differences lead to foundation displacements, which cause a series of problems such as GIS equipment bellows bending, cylinder cracking, and SF6 gas leakage. Before the ...
