Embodiment

The utility model is described further below in conjunction with the accompanying drawings.

Embodiment 1

As shown in figure 1, a kind of transient state recording type data acquisition unit, including power module 1, data acquisition module 2, data Processing module 3 and communication module 4, the power module 1 respectively with data acquisition module 2, data processing module 3 and communication module 4 are connected, and the data acquisition module 2 is connected by data processing module 3 with communication module 4, and the data acquisition module 2 includes Induction coil and a/d converter, the data processing module 3 include memory and microprocessor, and the communication module 4 includes RF Wireless transceiver.

The utility model utilizes coil-induced technology, telemetry, data processing technique, automatic technology, artificial intelligence Technology measures the operational factor of electric distribution network overhead wire in real time, the operation of electric distribution network overhead wire start when breaking down preceding 4 Individual cycle, start after 8 cycles, be no less than 80 sampled points per cycle, by analyzing, recording these data, find out its it is interior Basic reason, for future establish fault model, prejudge and the failure reason analysis of failure mode provide comprehensive scientific basis, Power module is that data acquisition module, data processing module and communication module etc. provide power supply, at data acquisition module and data Reason module can monitor the operation informations such as circuit three-phase load electric current, fault current, phase electric-field intensity and main power supply, back-up source Etc. status information and possesses failure wave-recording function, communication module is used to related data information upload to main website, and passes through foundation Two kinds of different data of service data and fault data, and constantly accumulation updates the data, and constantly expands Distribution Network Frame ceases to be busy The information content of road operation characteristic, to monitor the real time status of power distribution network, when system jam, recorded with the mode of recording Failure dynamic process, so as to establish a kind of reliable fault distinguishing mechanism to prevent distribution network fault line selection and the malfunction of positioning Make, refused action, reliability, economy and the security of power distribution network are fundamentally improved, in order to ensure field long-time stable work Make, this transient state recording type data acquisition unit must solve powerup issue, and solar energy is extensive as a kind of clean energy resource Using, but only can be by sunshine power taking on daytime, at night or sleety weather especially plum rain season can not effectively take Electricity, therefore, this transient state recording type data acquisition unit employ the main power supply of TA electricity-fetching modules and super capacitor, and non-fill Battery realizes the round-the-clock monitoring of power distribution network as back-up source.
