[accompanying drawing explanation]
Below in conjunction with accompanying drawing, the present invention is described further:
Fig. 1 is principle schematic of the present invention.
[embodiment]
The invention provides a kind of high-voltage fence ultraviolet ray on-line monitoring system, comprise ultraviolet detection instrument, wireless sending module and for the master control platform of data processing, high-tension apparatus in ultraviolet detection instrument monitoring high-voltage fence, ultraviolet detection instrument connects wireless sending module, and ultraviolet detection instrument carries out data transmission by wireless sending module and master control platform.Ultraviolet detection instrument can detect the corona discharge situation of national grid round-the-clock, in real time; And realize remote monitoring corona discharge situation by wireless transmission method, detect the reduction of equipment initial failure and performance.
Accompanying drawing below in conjunction with the embodiment of the present invention is explained and illustrated the technical scheme of the embodiment of the present invention, but following embodiment is only the preferred embodiments of the present invention, not all.Embodiment based in embodiment, those skilled in the art are other embodiment that obtains under the prerequisite of not making creative work, all belongs to protection scope of the present invention.
With reference to figure 1, shown high-voltage fence ultraviolet ray on-line monitoring system, comprise detecting module 2 and master control platform 1, detecting module 2 comprises ultraviolet detection instrument 21 and wireless sending module 22, ultraviolet detection instrument 21 is placed near high-voltage fence 3 mesohigh equipment, the corona discharge situation of monitoring high-tension apparatus; Ultraviolet detection instrument 21 connects wireless sending module 22, by wireless sending module 22 and master control platform 1, carries out data transmission, and testing staff can the corona discharge situation to high-voltage fence carry out Real-Time Monitoring from master control platform 1.
Wherein master control platform 1 comprises far-end server 11, economizes corporate gateway 12, PI database 13 and user interface 14, far-end server 11 receives the detection signal of wireless sending module 22, economizing corporate gateway 12 is connected between far-end server 11 and PI database 13, economizing corporate gateway 12 repacks the data of far-end server 11 to deposit PI database 13 in, user interface 14 connects the variation that PI database 13 shows monitor value, user interface 14 is drawn change curve according to the data of PI database 13, and gives a warning during by superthreshold at measured value.
The high-tension apparatus that easily produces corona in high-voltage fence 3 comprises damaged bronze medal 32 in the insulator 31, transformer station on ultra-high-tension power transmission line and the porcelain vase 33 in transformer and lightning arrester, therefore ultraviolet detection instrument 21 is mainly arranged near this three, on ultraviolet detection instrument 21, be all connected with wireless sending module 22, wireless sending module 22 carries out networking with same master control platform 1.
By supply module 23 simultaneously for ultraviolet detection instrument 21 and wireless sending module 22 are powered.Supply module 23 adopts two kinds of solar powered module or Switching Power Supplies according to the difference of placement location.Solar powered module is comprised of solar panels and battery, and the ultraviolet detection instrument on outdoor high-voltage transmission line of electricity is selected by solar powered module, can be at the overcast and rainy lower normal power supply that continues about 10 days; Transformer station's inner high voltage equipment selector switch Power supply, Switching Power Supply changes into the source current of transformer station the supply current of ultraviolet detection instrument and wireless sending module, as long as transformer station's power lead does not cut off, power supply for a long time.
