Description
Technical field
The utility model relates to transformer monitoring technical field, particularly, relates to a kind of transformer oil quality on-line monitoring device.
Background technology
In electric system, transformer is comparatively large and position the is important equipment of investing, but transformer be in operation stand for a long time electrically, the impact of machinery, chemistry and environment.Transformer oil is subject to these impacts too, and these composite factors must cause some technical indicator of transformer oil can not meet transformer safety service requirement.Although preventive trial has played great function in China's electric system, the method for this monitoring and maintenance has on schedule had certain defect, and not only the defect of equipment can not find immediately, not only waste of manpower and financial resources but also can not get a desired effect completely.In addition, its major defect is the real-time technique index that the technical indicator of the transformer oil detected when laboratory truly can not reflect transformer oil in charged situation.Say nothing of process in real time of pinpointing the problems in real time, to avoid the generation of Accident of Transformer.(state) monitoring is just arisen at the historic moment thus online.Realize just must having on-line monitoring equipment to the status monitoring of electrical equipment, realize, to the real-time measurement of equipment, being only the status monitoring of real meaning.
The method that the traditional experiment of transformer oil dielectric strength is measured is off-line measurement entirely, and empirical evidence classic method is for many years feasible, at that time because the restriction of science and technology can only take off-line measurement, facts have proved that its measurement result has very large dispersiveness.Owing to causing the many factors of measuring error in measuring process, due to processing procedure lack control and high dispersion, some results be but not, particularly different time measure its numerical value of same oil sample widely different, cannot reasonably be explained.This is all because off-line measurement method truly can not reflect the quality institute of transformer oil extremely.
Realizing in process of the present utility model, inventor finds at least to exist in prior art the defect such as the low and scope of application of poor anti jamming capability, monitoring accuracy is little.
Utility model content
The purpose of this utility model is, for the problems referred to above, proposes a kind of transformer oil quality on-line monitoring device, to realize the advantage that antijamming capability is good, monitoring accuracy is high and the scope of application is large.
For achieving the above object, the technical solution adopted in the utility model is: a kind of transformer oil quality on-line monitoring device, comprise for monitoring and the first sensor outputed signal the liquid condition of transformer oil, for monitoring and the second sensor outputed signal the ambient conditions of transformer oil storage space outside, the data processing module be connected with described first sensor and the second sensor respectively, and the communication module, central controller and the output device that are connected with described data processing module successively.
Further, described output device, comprises the display and/or audible-visual annunciator that are connected with described central controller.
Further, described first sensor, be specially viscosity sensor, dielectric constant sensor, humidity sensor, temperature sensor and chemical composition absorption sensor in one or several.
Further, described second sensor, be specially in electric field strength transducer[sensor, magnetic field strength transducer, humidity sensor, temperature sensor and optical sensor one or several.
Further, described data processing module, specifically comprises CPU or single-chip microcomputer.
The transformer oil quality on-line monitoring device of each embodiment of the utility model, owing to comprising for monitoring and the first sensor outputed signal the liquid condition of transformer oil, for monitoring and the second sensor outputed signal the ambient conditions of transformer oil storage space outside, the data processing module be connected with first sensor and the second sensor respectively, and the communication module, central controller and the output device that are connected with data processing module successively; Thus poor anti jamming capability in prior art, monitoring accuracy is low and the scope of application is little defect can be overcome, to realize the advantage that antijamming capability is good, monitoring accuracy is high and the scope of application is large.

According to the utility model embodiment, as shown in Figure 1, a kind of transformer oil quality on-line monitoring device is provided.
Transformer oil quality on-line monitoring device of the present utility model, comprises first sensor, the second sensor, data processing module, communication module, audible-visual annunciator, display and central controller; First sensor is connected with data processing module respectively with the second sensing data output terminal, and data processing module is connected with central controller by communication module, and central controller is connected with audible-visual annunciator and display.
In the above-described embodiments, first sensor is used for monitoring the liquid condition of transformer oil, and outputs signal, and the second sensor is used for monitoring the ambient conditions of transformer oil storage space outside, and outputs signal.First sensor is connected with data processing module respectively with the second sensing data output terminal, and data processing module is connected with central controller by communication module, and central controller is connected with audible-visual annunciator and display.First sensor include viscosity sensor, dielectric constant sensor, humidity sensor, temperature sensor, chemical composition absorption sensor in one or several.Second sensor include in electric field strength transducer[sensor, magnetic field strength transducer, humidity sensor, temperature sensor, optical sensor one or several.
Transformer oil quality on-line monitoring device of the present utility model, in use, first sensor and the second sensor carry out Real-Time Monitoring to position respectively, send the transformer oil monitored oil data and the data of space outerpace to data processing module to process, then central controller is sent to by communication module, the Monitoring Data received compares with the correlation data preset by central controller in real time, when oil and the data of space outerpace and preset data have difference and difference exceedes certain limit, central controller sends alerting signal to audible-visual annunciator, audible-visual annunciator is reported to the police, the data compared are sent to display screen by central controller simultaneously, consult for staff, to keep in repair equipment.
The beneficial effects of the utility model are:
(1) can carry out real time on-line monitoring to transformer oil, to obtain the liquid condition of transformer oil, thus be convenient to the quality grasping transformer oil in real time.
(2) can also monitor the surrounding environment of the storage space outside of transformer oil, grasp the running status of equipment, thus the state of transformer oil internal and external environment is predicted, be convenient to better manage transformer equipment.
(3) when transformer oil quality goes wrong, this device can carry out Realtime Alerts, and by the display of transformer oil qualitative data over the display, ensure that the normal operation of equipment, and also just staff accurately keeps in repair simultaneously.Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
