Description
Technical field
The utility model relates to technical field of electric power, and in particular to a kind of survey for GIS bellows Analysis of Modal Characteristic
Test system.
Background technique
GIS(gas insulated combined electrical equipment) use sulfur hexafluoride gas as insulating materials, have occupied area small, safe
The high feature of the degree of reliability, has obtained a large amount of application in power grid at present.GIS can generate mechanical vibration in actual moving process
It is dynamic, if mechanical oscillation long-term existence, it will lead to equipment gas leakage or even endanger its insulation.In northwest China area, due to round the clock
The temperature difference is big, and GIS often installs the absorption that bellows carries out stress, but bellows its collapsing length etc. under the big temperature difference can occur
Variation, and then influence its characteristics of mode and change, scene also has occurred a lot of due to the big generated vibration of day and night temperature
Signal intensity is violent.
Measurement for GIS vibration signal has been carried out at present, but is directed to the research of this special object of bellows
It yet there are no and have been reported that, especially the change to its characteristics of mode when various operating conditions issue growth degree, retracted position changes
Situation is not clear at present.In view of this, the utility model provides a kind of test system for GIS bellows Analysis of Modal Characteristic
System, the system can obtain the change of bellows state to the affecting laws of its characteristics of mode by test.
Utility model content
The utility model provides a kind of test system for GIS bellows Analysis of Modal Characteristic in view of the deficiencies of the prior art
System, it is characterised in that: it hammers (1), vibrating sensor (2), GIS cavity (3), bellows (4), oscillograph (5) group into shape by impact force
At the system can study change of the change to its characteristics of mode of bellows in GIS, provide more for the design and operation of GIS
For accurate data, in one end of GIS bellows using impact force hammer (1) as pumping signal, the other end utilizes vibrating sensing
Device (2) detects response signal, is advised by the variation that calculation of transfer function obtains its characteristics of mode when bellows (4) state changes
Rule, length, the tightening state of bellows (4) are adjustable, record pumping signal and response signal simultaneously by oscillograph (5), and
Calculation of transfer function.
The utility model has the beneficial effects that: can grasp telescopic joint by the implementation of this patent and believe GIS mechanical oscillation
Number affecting laws, improve site inspection signal accurate analysis degree, provide beneficial side for the detection of GIS mechanical defect
It helping, the utility model structure is simple, and it is easy to operate, reduce labor intensity.
Detailed description of the invention:
Fig. 1 is the application schematic diagram of the utility model；
Wherein: 1, impact force is hammered into shape；2, vibrating sensor；3, GIS cavity；4, bellows；5, oscillograph.
Specific embodiment
Embodiment 1, the utility model provides a kind of test macro for GIS bellows Analysis of Modal Characteristic, described
System includes impact force hammer (1), vibrating sensor (2), GIS cavity (3), bellows (4), oscillograph (5) composition.Its feature exists
In: the system can study change of the change to its characteristics of mode of bellows in GIS, provide more for the design and operation of GIS
For accurate data.
The utility model can be configured and simulate in entity GIS, wherein (1) is impact force hammer, impact force hammer is mould
The common tool of state analysis, carries the sensor of measurement excitation, its signal can be introduced oscillograph.Impact force hammer is produced
Raw pumping signal is applied to the side of bellows (4), and (2) are the measurement response signal for being arranged in bellows (4) other side
Vibrating sensor.Impact force hammer can be taken as from belt sensor with the parameter of (2) consistent.(3) cavity is tested for GIS, can is practical
GIS can also be Special test cavity.The state of bellows (4) is adjustable, and collapsing length, degreeof tortuosity can be according to tests
Demand is adjusted.The signal of (1) and (2) is introduced oscillograph (5) simultaneously, the oscillography of 3032 model of Tyke can be used in oscillograph (5)
Device.
The time-domain signal that oscillograph obtains (1) is recorded as f1 (t), and the time-domain signal of (2) of acquisition is recorded as f2 (t), then
It is carried out Fast Fourier Transform (FFT) and is converted to frequency domain, and carry out division arithmetic, can get its transmission function, according to transmission function
The variation of extreme point can get the variation of its characteristics of mode.
The utility model is described in detail above, specific case used herein is to the principles of the present invention
And embodiment is expounded, the method and its core of the above embodiments are only used to help understand the utility model
Thought；Meanwhile for those skilled in the art, based on the idea of the present invention, in specific embodiments and applications
There will be changes, in conclusion the content of the present specification should not be construed as a limitation of the present invention.
