Description
Technical field
The present invention relates to the auxiliary equipment of a kind of power equipment, especially relate to a kind of ensure what power equipment safety ran
Monitoring system.
Background technology
Along with increasingly expanding of structure and the improving constantly of voltage apparatus grade of power industry, the maintenance of transformator more comes
The most important, and wherein the moisture measurement in transformer oil has become as a part the heaviest during transformator is safeguarded, aqueous in oil
Amount has decisive action substantially in the safe operation of transformator, and the insulating properties of transformer oil is played certainly by the content of moisture
Affecting qualitatively, water content too much in oil will accelerate the aging of insulant, and reduces insulating properties, and then causes equipment to run
Instability and potential danger, coil can be caused the when that water content being big to produce arc ring and short circuit phenomenon, even at some
In the case of blast etc. can occur.According to GB50150-2006 " Erection works of electrical installations Standard for handover test of electric equipment ", oil
The measurement of middle minor amount of water has to comply with certain regulation.Micro-water content in laboratory offline inspection insulating oil, operation complexity is difficult to
Controlling, it is big that especially oil-water separation link realizes difficulty, and transformator is far multiple to detection process from taking oil to laboratory distance simultaneously
Miscellaneous cost is high, poor real；Online micro-water monitoring is effectively supplementing and perfect of the micro-water monitoring of laboratory.Application is
The patent of CN200820056711 discloses in a kind of gas chromatograph the injector of determination of water, this kind in transformer oil
Detection method is highly sensitive, and interference is little, but operation is more complicated, general technical staff be difficult to hold and equipment requirements relatively
Height, nor beneficially on-line monitoring.The invention provides a kind of on-line monitoring system with radio frequency detector unit, this work
Systematic survey speed is fast, strong anti-interference performance, and can detect the moisture changing condition in transformator in real time.
Summary of the invention
The present invention provides a kind of monitoring system ensureing that power equipment safety runs, and it includes radio frequency detector unit, data
Processing unit, client's monitoring terminal.Wherein, described radio frequency detector unit comprises radio-frequency signal source and condenser type radio frequency sensor
Load；Described data processing unit is the industrial embedded computer of Based PC/104 bus；Described client's monitoring terminal
Equipped with micro-moisture fault diagnosis software.The present invention, by the moisture changing condition in on-line measurement transformer oil, has reached fortune
Line stabilization, measuring speed is fast, timely early warning thus ensure the purpose that transformer safety is run.
Accompanying drawing explanation
Fig. 1 is the device connection diagram that the present invention ensures the monitoring system that power equipment safety runs.
Detailed description of the invention
As shown in Figure 1,It it is the device connection diagram of the monitoring system that guarantee power equipment safety of the present invention runs.
The present invention provides a kind of monitoring system ensureing that power equipment safety runs, it include radio frequency detector unit, data processing unit,
Client's monitoring terminal.Wherein, described radio frequency detector unit comprises radio-frequency signal source and condenser type radio frequency sensor load；Described
The industrial embedded computer that data processing unit is Based PC/104 bus；Described client's monitoring terminal is equipped with minor amount of water
Divide fault diagnosis software.When system works, radio-frequency signal source launches radiofrequency signal, and owing to oil is apolar substance, water is pole
Property material, both dielectric constants are very big, thus present different RF impedance characteristics.When radiofrequency signal be sent to
When oil is the condenser type radio frequency sensor load of medium, this load impedance changes along with oil-water ratios different in mixed liquor, becomes
Change signal and enter the industrial embedded computer of Based PC/104 bus, export the content of water content in oil, Ke Hujian after treatment
Depending on terminal equipped with micro-moisture fault diagnosis software, check measured Water Content in Transformer Oil, and according to transformer oil
Middle moisture, it may be judged whether produce fault related to this or predict the fault that will occur.Embodiment in the present invention is only used for
The present invention will be described, is not intended that the restriction to right, those skilled in that art it is contemplated that other
The replacement being substantially equal to, all in scope.
