Embodiment
As shown in Figure 1 and Figure 2, the utility model is provided with baffle plate 10 on each electric power tower 11 top of transmission line of electricity, and baffle plate 10 belows are provided with arc sensor 1.Above-mentioned arc sensor 1 can be photoresistance, also can pop one's head in for arclight.When arc sensor 1 was photoresistance, this photoresistance was for there being the resistance of resistance variations reaction to the arclight wavelength.When arclight took place, under the effect of arclight, this photoresistance resistance sharply descended, and makes arc light detecting unit 2 start working.Arc sensor 1 sends arc light detecting unit 2 to after the arclight conversion of signals of obtaining can being become electric signal like this, arc light detecting unit 2 generates drive signal according to the electric arc electric signal that receives and exports microprocessor 3 to, the time of arc light detecting unit record electric arc generation simultaneously; Microprocessor 3 generates control signal according to drive signal, and this control signal and the electric arc time of origin that receives are sent to centralized control platform 5 by wireless communication module 4.Wherein, above-mentioned arc light detecting unit 2, microprocessor 3, wireless communication module 4 all are connected with power module 6, consider the applied place of the utility model, power module 6 is made of the inductive coil that is wrapped on the electric power tower, and the principle of work of power module 6 is a technology well known to those of ordinary skill in the art.And the principle of work of above-mentioned arc light detecting unit 2 also is the known technology of the common staff in this area.
As shown in Figure 3, at 0-t
0The moment or t
0In-t the moment, this moment, arclight took place as yet, so voltage is in low level state always, arc light detecting unit 2 does not have conducting.And work as t
0When constantly taking place, arc sensor 1 resistance sharply descends, and the voltage value signal that obtains increases rapidly, the 2 conducting work of arc light detecting unit, and then follow-up control circuit work.After microprocessor 3 was sent to centralized control platform 5 with this control signal and the electric arc time of origin that receives by wireless communication module 4, wherein centralized control platform 5 comprised central processing system and the warning system that is connected with central processing system.Central processing system when being judged as the arclight generation, is in time sent warning by warning system according to the time that electric arc takes place, and makes things convenient for the staff to rush to repair.
