Description
Technical field
The disc insulator that the utility model is related to a kind of GIS loosens the accessory system detected, belongs to electric automatization skill
Art field.
Background technology
Gas insulated combined electrical equipment (Gas Insulated Switchgear, abbreviation GIS) is various electricity in electric substation
Gas equipment in addition to transformer all combination be assemblied in one closing metal shell in, GIS air chambers by disc insulator isolate and
The indoor SF6 gases filled with certain pressure intensity, to realize conductor the reliable insulation shell, alternate and fracture.GIS has
The advantages of compact conformation, operational reliability are high and easy for installation.
Disc insulator in GIS plays a part of isolation air chamber and supports high-voltage conductive rod, and disc insulator is usually
It is connected by bolt by flange hole.The improper failure that bolt can be caused to fix of manufacture, transport and installation as GIS；This
Acted on outside by electromagnetic force, the vibration of GIS operation duration times can also reduce the fastening effect of bolt, exhausted which results in benzvalene form
The looseness fault of edge.Disc insulator, which loosens, to cause the leakage of SF6 gases to influence the operation of whole generalized information system to pacify
Entirely.
Existing monitoring/detection for GIS is typically to be carried out around the air pressure of GIS device, when being capable of detecting when air pressure
During problem, the problem of GIS has occurred running safe can not will appear from preventing trouble before it happens during problem, it is necessary to safeguarded shortly.
Utility model content
The technical problems to be solved in the utility model is, in view of the shortcomings of the prior art, proposing a kind of benzvalene form for for GIS

The technical scheme that in order to solve the above-mentioned technical problem the utility model proposes is：A kind of disc insulator pine of GIS
The accessory system of dynamic detection, including sensor, impulsive force hammer module, signal acquisition module；The sensor absorption is in the basin
In the fastening bolt of formula insulator, the sensor and impulsive force hammer module are connected with the signal acquisition module；Institute
State signal acquisition module to be connected with backend machine, and the signal collected is transferred to backend machine；
Signal acquisition module is used for the power hammer percussion of the excited vibration signal for gathering fastening bolt and impulsive force hammer module
Acceleration signal.
The improvement of above-mentioned technical proposal is：The sensor axis is pressed to fastening bolt of the absorption in the disc insulator
On head.
The improvement of above-mentioned technical proposal is：The sensor is acceleration transducer.
The improvement of above-mentioned technical proposal is：The percussion dynamics of the power hammer is constant all the time, and is tapped by predeterminated frequency.
The utility model is using the beneficial effect of above-mentioned technical proposal：The utility model by sensor by being installed on basin
In the fastening bolt of formula insulator, by constantly entering row energization, to obtain the vibration data of fastening bolt；
1）By the way that acceleration transducer is installed in the axial direction of fastening bolt, to obtain the vibration number on specific direction
According to provide authentic data for backend machine.
2）Power hammer is continuously applied to constant excitation, and to control variable, controllable comparison data are provided for the analysis of backend machine.
