Description
Technical field
The utility model relates to a kind of support insulator vibration detection servicing unit, be applicable to each electric pressure transformer station, hydraulic power plant and fuel-burning power plant, filth cleaning before can detecting the support insulator of its used various grades and detection position are taken and monitoring.
Background technology
The support insulator vibration detection is that the support insulator at power equipment is in operation and is subjected to the effect of electricity, heat and mechanical stress and environmental stress, and its performance can descend gradually, and state of insulation can deterioration, finally loses insulation function.The aging of power equipment insulation is the process of a gradual change, if untimely discovery just may cause power equipment to break down, even cause paroxysmal electric power accident, causes huge direct and indirect economic loss.The specifically theoretical research that vibroacoustics is detected is set up the theoretical foundation that the support insulator vibroacoustics detects with theory of classical physics.To the research of vibroacoustics checkout equipment, introduce digestion, absorb Muscovite vibroacoustics checkout equipment, develop detection system.To the research of vibroacoustics detection method, on the basis of theory research, sum up the characterization processes method in conjunction with site test, set up the criterion of the physical strength situation of assessment support insulator.It can be measured at any time to the insulation parameter of monitored equipment, has shortened the detection time of operational outfit widely, for the safe operation of electric system provides reliable assurance.
The insulating bar of the main involving vibrations detector of existing support insulator vibration detection equipment, detector bottom and the detection contact that is installed in the top.During the detection support insulator, detection contact is against insulator flange bottom, the acoustic signal that contact sends is inner through reflection at insulator, and reflected signal passes to computing machine and carries out the software analysis processing.The technician analyzes the inherent vice of support insulator according to the reflected signal feature.Yet, in actual mechanical process, particularly being in the support insulator of higher position, before the detection, whether the technician does not see the support insulator flange in the bottom usually clean.If filth (as liver moss) is arranged at the support insulator bottom, the effect that vibration-detecting instrument detects will be affected, even the situation of defective erroneous judgement occurs.
In order to address the above problem, must before detect support insulator, it be detected position carry out filth cleaning, to the monitoring of taking pictures of detection position, it is clean to guarantee to detect the position.
The device that the utility model relates to is provided with monitoring camera and clearing apparatus respectively in vibration-detecting instrument top contact both sides, can realize the cleaning of support insulator and the monitoring that detects the position.
The utility model content
The purpose of this utility model is that some inconvenience when using at the scene at existing support insulator vibration detection equipment is optimized improvement, reaches the purpose that improves detection efficiency and accuracy rate.
The utility model is realized by following technical proposal.
A kind of support insulator vibration detection servicing unit, the utility model is characterised in that, is made of camera head and clearing apparatus; Wherein: camera head comprises: be positioned at the camera at vibration-detecting instrument top, connect the rods of camera and vibration-detecting instrument, connect the data line of camera and computing machine; Purging system comprises: the cleaning head that is positioned at the vibration-detecting instrument top, the L type bar that connects vibration-detecting instrument and cleaning head, be positioned at the battery and the motor of cleaning head and L type bar junction, the universal stage that links to each other with motor, the vibration-detecting instrument insulating bar is positioned at the vibration-detecting instrument bottom, is provided with the switch that connects lead at vibration-detecting instrument insulating bar afterbody.
The utility model rods adopts with vibration-detecting instrument and is threaded, and L type bar adopts with vibration-detecting instrument and is threaded; Connect by gluing between cleaning head and universal stage, cleaning head is replaceable.
The brush of the utility model cleaning head is made by harder hair, can dismounting and change.
Rods is bend fixing arbitrarily, thereby the orientation that realizes camera changes.
Rods and L type bar adopt insulating material or carry out insulation processing.
The beneficial effects of the utility model are before detecting support insulator, to utilize this servicing unit to detect the position to insulator and carry out the filth cleaning; In the testing process process, can take, determine to detect the position, and really it not have filthy detecting the position.Therefore, this device can improve efficient and the accuracy rate that the support insulator vibroacoustics detects.
