Description
Technical field
The utility model relates to a kind of monitoring system, metal oxide arrester intelligent wireless is monitored in specifically a kind of station
System.
Background technique
Existing arrester on-line monitoring mode is all to constitute arrester on-line monitoring system using wired mode, that is, is used
Communication cable connects the sensor of arrester front end and data acquisition device, to realize the system for interior all arresters of standing
One Centralizing inspection.But since arrester has the characteristics that distribution is wide, quantity is more in station, and major part is all distributed in power transformation
The marginal position stood causes to lay a large amount of cable in station using wired mode monitoring needs, needs so as to cause in construction
It buys a large amount of cable, also to increase construction period, also to reopen long range when being especially transformed to old station
Cable duct carries out the laying of cable, and the construction of this part will at least increase the system cost of one third.If using nothing
Line mode carries out arrester on-line intelligence monitoring, can to avoid constructional difficulties, it is at high cost the disadvantages of.It can be with for newly-built substation
Reduce construction cost and material cost, transformation can be more convenient for standing always, eliminates the communication of a large amount of long ranges and wide scope
The laying of cable, is mounted directly wireless launcher, can facilitate in the case where reducing cost and realize all built substations
Arrester intelligent online monitor transformation.Therefore, the development of intelligent wireless monitoring system will be supervised to arrester intelligent online is realized
The universal and real-time status prediction surveyed has great importance.
Therefore the design provides one kind and is detected by detecting current in resistance property to signal, and with wireless transmission function
Detection system.
Utility model content
The purpose of this utility model is to provide a kind of smart bluetooth voice control devices, to solve in above-mentioned background technique
The problem of proposition.
To achieve the above object, the utility model provides the following technical solutions:
Metal oxide arrester intelligent wireless monitors system in a kind of station, including single-chip microcontroller, power module, alarm,
Inquiry button, display, GPRS module and current detection module, the current detection module acquisition arrester are operating normally electricity
The current in resistance property signal of pressure is simultaneously transferred to single-chip microcontroller, single-chip microcontroller be also respectively connected power module, alarm, inquiry button,
Display and GPRS module.
As a further solution of the present invention: the current detection module is current transformer.
As a further solution of the present invention: the model AT89C52 of the single-chip microcontroller.
As a further solution of the present invention: the display is the liquid crystal display with touch function.
As a further solution of the present invention: the power supply is the ups power for including mains-supplied and battery.
Compared with prior art, the utility model has the beneficial effects that metal oxide arrester in the utility model station
Intelligent wireless monitors system and uses whether normal key is correctly to determine resistive electricity in follow current by detection MOA operation
Whether stream fundamental wave and harmonic wave there is increment, i.e. current in resistance property increment occurs and reaches detection to arrester state, and has wireless
Transfer function.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of metal oxide arrester intelligent wireless monitoring system in standing.
Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment.
Referring to Fig. 1, embodiment one: metal oxide arrester intelligent wireless monitors system in a kind of station, including is used for
The single-chip microcontroller of Comprehensive Signal Processing, for each electricity consumption module for power supply power module, in abnormal cases issue report
The alarm of alert sound, the display for showing testing result, is used for nothing at the inquiry button for being manually entered command signal
The GPRS module and current detection module of line signal transmission, the current detection module acquisition arrester is under normal operating voltage
Current in resistance property signal and be transferred to single-chip microcontroller, power module, alarm, inquiry button, display is also respectively connected in single-chip microcontroller
Device and GPRS module.Single-chip microcontroller can carry out remote signal transmission by GPRS module, be may be used also encountering testing result extremely
To issue alarm sound by alarm.
Why can judge that the state of arrester is based on following principle by sensed current signal: Zinc-Oxide Arrester
(MOA) degradation, there are two reason is main: first is that poorly sealed in arrester structure cause internal wetted, characteristic quantity
It is the current in resistance property increase under system normal operating voltage, the increase of fundamental wave amount becomes apparent；Second is that since zinc oxide valve plate is long-term
It bears power-frequency voltage and is easy to aging, so that its nonlinear characteristic is deteriorated, characteristic quantity is also the resistance under system normal operating voltage
Property electric current increase, but higher harmonic components are more significant.No matter above-mentioned which kind of situation is occurred, and result can all cause current in resistance property
Increase.Therefore, whether normal key is correctly to determine resistive current first harmonics and harmonic wave in follow current for detection MOA operation
Whether increment is occurred, i.e. increment occurs in current in resistance property.
Embodiment two: on the basis of example 1, the model AT89C52 of the single-chip microcontroller of the design.Display is band
There is the liquid crystal display of touch function.Therefore the inquiry and instruction of related data can be not only carried out by inquiry button above
Input, can also directly be inputted by liquid crystal display, power supply is the ups power for including mains-supplied and battery,
Accordingly even when occurring alternating current power-off in use, it is also ensured that the uninterrupted operation of this system.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new
The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing for the equivalent requirements of the claims will be fallen in
All changes in justice and range are embraced therein.It should not treat any reference in the claims as limiting
Related claim.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
The other embodiments being understood that.
