Embodiment
It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the application can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.
A kind of surge arrester failure indicating means is provided in the present embodiment, and Fig. 1 is that as shown in Figure 1, the method comprises the steps: according to the process flow diagram of the surge arrester failure indicating means of the embodiment of the present invention
Whether step S102, have electric current to flow through on the ground path of detection lightning arrester;
Step S104, in the situation that having electric current to flow through, indicates this arrester ground fault.
The present embodiment passes through above-mentioned steps, when puncturing, causes after single-phase earthing by lightning arrester, on ground wire, having ground current flows through, therefore, on the ground path that lightning arrester detected, have electric current flows through, indicate this arrester ground fault, thereby track walker can directly find the lightning arrester breaking down according to this indication, check without the mode of lightning arrester electric pole being stepped on one by one to bar, solve the problem that in correlation technique, the mode of searching of surge arrester failure wastes time and energy, reduce the trouble shooting time of lightning arrester, and save track walker's muscle power, avoid stepping on the safety problem being prone in bar process.
Lightning arrester occurs that the situation of earth fault divides two kinds, and a kind of is the earth fault that overvoltage produces, and lightning arrester itself is damage not, can recover voluntarily over time; Another kind is the earth fault that punctures generation, and lightning arrester damages, and cannot recover voluntarily.Therefore as a kind of preferred implementation, whether after indication arrester ground fault, can also continue to detect on the ground path of lightning arrester has electric current to flow through; For example, flow through if no longer include electric current on (, 24 hours) ground path in Preset Time, cancel the indication of arrester ground fault; And if on ground path, still have electric current to flow through, can keep indicating arrester ground fault.In this way, in the time that tour personnel check, can distinguish exactly the lightning arrester and the unspoiled lightning arrester that in fault lightning arrester, damage, and can change the lightning arrester damaging, shorten the time of troubleshooting and processing.
Preferably, whether the ground path that can detect lightning arrester by current transformer around produces alternating magnetic field, and in the situation that producing alternating magnetic field, determines on the ground path of lightning arrester and has electric current to flow through.Wherein, what detect due to this scheme is earth fault, therefore can adopt zero sequence current mutual inductor to detect.
Preferably, the mode that can report to the police by alarm corresponding to triggering lightning arrester is indicated arrester ground fault.For example, can trigger the board turning alarm that lightning arrester is corresponding and carry out board turning warning, in this way, in the time that tour personnel see board turning alarm, just can know whether earth fault of lightning arrester, which is saved the energy; Also can trigger the flash alarm that lightning arrester is corresponding and carry out flashing light alarm, in this way, can make tour personnel just can find the lightning arrester of earth fault in far place, promote search efficiency.
Preferably, this programme can be applied in the situation that detects Zinc-Oxide Arrester earth fault, and for other lightning arresters, this programme also can be applied.
