Put.
To achieve the above object, technical scheme is used by the utility model：
A kind of GIS bus bar canisters stress tilt angle monitoring device, mother of the GIS bus bar canisters by some sections of axis on the same line
Spool body is spliced by bellows, and the both ends of bellows are connected by ring flange with two bus cylinders respectively, positioned at one
The outer wall bottom of one of bus cylinder of individual bellows both sides is fixedly installed resistance scale, and resistance scale is internally provided with can
The slider I slided on resistance wire, slider I are connected by steel band with the sliding support of bus cylinder body bottom, and sliding support includes
The base that fixes on the ground, the pole being connected with base and be connected with pole and in the guide groove of bus cylinder body outer wall bottom with
The sliding block II of steel band connection；Inclination angle monitoring modular is further fixed on bus cylinder body outer wall, inclination angle monitoring modular includes foil gauge, answered
The firm layer become above tack coat and foil gauge below piece, it is that rubber presoaks aryl fiber cloth to consolidate layer.
Stirrup is fixed with outside described inclination angle monitoring modular.
Described foil gauge sensitive grid and covering made of basal disc film and the thin metal foil being attached on basal disc film
Laminated film on sensitive grid is formed.
Described basal disc film and laminated film are polyurethane elastomer material, and described thin metal foil is chromiumcopper material
Material.
In the utility model, tack coat is double face binding in the monitoring modular of inclination angle, and foil gauge is pasted in tack coat upper surface, under
Surface is bonded in bus cylinder body outer wall；The rubber that described firm layer uses presoaks aryl fiber cloth to be commercially available, foil gauge circuit
Using four strain gauge methods, i.e. four sides of bridge are all connected to foil gauge.
Compared with prior art, the utility model has the advantages that：
The utility model, the sliding block of the resistance scale of bus drum outer wall pass through steel cable and the sliding support being fixed on bottom surface
Sliding block is connected, and when bus bar canister axially deforms upon, sliding support is moved by the sliding block of steel strip driving resistance scale, passes through resistance
The resistance of chi changes, the deformation of monitoring bus barrel axial direction；Furthermore when strain radial distorted occurs for bus barrel, the torsion of barrel
Song drives the foil gauge for the inclination angle monitoring modular for being close to barrel to change, and monitoring bus bar canister by the change of foil gauge radially turns round
Song, inclination angle detection module and resistance scale are connected with monitoring system, it is achieved thereby that monitoring bus cylinder attitudes vibration in real time, greatly
The precision of measurement is improved while big saving manpower；Further, since bus bar canister strain is quite small, so caused electricity
Resistiveization is also extremely small, so the thin metal foil sensitive grid of foil gauge of the present utility model is closed from the smaller copper chromium of strain constant
Golden material；Furthermore on the one hand the firm layer of the module of inclination angle monitoring is provided equal using rubber preimpregnation aryl fiber cloth to foil gauge
Even adhesive force, when the twist distortion of very little occurs for bus cylinder, just energy sensitive detection arrives foil gauge, on the other hand impregnates
Rubber layer can play protective layer effect, windproof and rain proof；In addition, two neighboring bus cylinder is connected by bellows, work as bus bar canister
When generation axial deformation and radial distorted strain, deformation quantity and stress can be absorbed by bellows.
