Another method is that fault detector is installed on the line, when fault takes place, and all fault detector board turning from transformer station to the fault nidus, thereby indication fault position.Utilize present fault detector to search fault, after fault takes place, transformer substation switch tripping operation or ground signalling are reported to the police, this signal is passed to the dispatching center, the dispatching center is according to the signalisation related personnel, and the related personnel begins to go on along circuit from transformer station, finds last board turning indicator, just can find fault section, quite waste time and energy.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of Automatic Fault Located device is provided.
Automatic Fault Located device of the present utility model is to be provided with fault detector on the power distribution network circuit, to be provided with monitoring substation ST and master station formation near the power distribution network circuit.Fault detector is made of fault probe FD and signal projector; Fault detector passes through the characteristic frequency wireless connections with monitoring substation ST; The monitoring substation is connected with the master station wireless telecommunications.
As further improvement of the utility model, fault probe FD is made of power circuit, filtering circuit, sample circuit, CPU, communicating circuit; Power circuit connects electro-induction coil L, telefault L connects the input end of filtering circuit, filtering circuit enters communicating circuit output wireless transmission signal after CPU handles, sample circuit inputs to control CPU from the current signal of gathering between electro-induction coil L and the filtering circuit.Signal projector comprises failure detector circuit, CPU, frequency synthesizer circuit, power amplifier, the input end of failure detector circuit is connected on the secondary side winding of transformer station, after rectification, each phase voltage information sampled respectively and transfer to CPU, the control signal of CPU output simultaneously is connected to the control end of frequency synthesizer circuit and power amplifier, the frequency synthesis loop produces the input end that a particular frequencies signal is delivered to power amplifier, after power amplifier amplified signal, the secondary failure that exports transformer station to went up mutually.Monitoring substation ST is connected to modulator-demodular unit, is constituted through gsm communication module and the transmission of SIM cards of mobile phones note by receiver.Master station comprises receiver, A/D converter, modulator-demodular unit, I/O interface and computing machine, and receiver will be transferred to computing machine by A/D converter, modulator-demodular unit, I/O interface successively by the signal that each probe is beamed back.
Automatic Fault Located device of the present utility model is to have increased a low power wireless launcher in fault detector inside, and the detected fault-signal of fault detector becomes wireless signal transmission and goes out when fault takes place; After being installed in wireless signal that substation in 20～200 meters scopes of distance fault detecting device receives the wireless launcher emission and mediating, the failure message that obtains is sent to master station in the mode of SMS (short message service); Main website handles the message that obtains and shows that the maintenance personal can directly fix a breakdown to the position of fault.
Automatic Fault Located device of the present utility model is reasonable in design, safe and reliable, degree of accuracy is high, and cost is low, has reduced working strength of workers, increases work efficiency.
