Embodiment Construction

[0027] Example of deformation monitoring system for tie-rod bellows:

[0028] The deformation monitoring system of the tie-rod bellows such as figure 1 As shown, it includes a fiber grating strain sensor, a fiber grating displacement sensor, a fiber grating temperature sensor, and a monitoring device. The monitoring device includes a power module, a signal acquisition unit, a data processing unit and a communication conversion unit.

[0029] The specific structure of the tie rod bellows is as follows: figure 2 As shown, including a pair of flanges 6 arranged oppositely, and a wave 4 of bellows arranged on the inner side of the pair of flanges 6, a number of tie rods 5 are interspersed on the pair of flanges 6, and along the flanges 6 6 is evenly arranged in the circumferential direction, the tie rod 5 is fixed on the flange 6 by the M20 hexagon nut 1, and the M20 gasket 2 is arranged between the flange 6 and the M20 hexagon nut 1.

Abstract

The invention relates to a deformation monitoring system of a tie rod type corrugated pipe, belonging to the technical field of electric power operation and maintenance. The monitoring system includes: displacement sensor, fixed on the flange, used to measure the displacement of the bellows when the expansion and contraction of the bellows is within the moving range of the tie rod; strain sensor, fixed on the tie rod, used to measure the expansion and contraction of the bellows The stress of the pull rod beyond the moving range of the pull rod; the temperature sensor, fixed on the flange; the monitoring device, including the signal acquisition unit, and the data processing unit; the displacement sensor, the strain sensor and the temperature sensor are all connected with the signal acquisition unit to pass the The data measured by the displacement sensor, strain sensor and temperature sensor obtain the deformation state of the bellows. The invention realizes the comprehensive monitoring of the bellows shape, and only needs to install the corresponding sensor on the tie-rod bellows without changing the body structure of the GIS, and the disassembly and installation are very convenient.

Description

technical field [0001] The invention relates to a deformation monitoring system of a tie rod type corrugated pipe, belonging to the technical field of electric power operation and maintenance. Background technique [0002] SF 6 The single-phase length of the gas-insulated metal-enclosed combined electrical appliances (referred to as GIS combined electrical appliances) reaches more than 200 meters. In order to facilitate the installation of long busbars, compensate for the relative displacement between foundations, and compensate for the displacement caused by thermal expansion and contraction, etc. Changes, high-voltage combined electrical appliances usually use metal bellows as the connecting component between two adjacent equipment shells. In the field application process, it is found that this type of combined electrical appliance, especially the long tubular busbar, will change due to environmental temperature difference or relative displacement between the foundations....
