The utility model content
The utility model has overcome shortcoming of the prior art, and a kind of wireless data acquisition device with self-powered function is provided, and has realized the data acquisition equipment self-powered steadily in the long term in the ultra-high-tension power transmission line in transformer station or power plant.
The technical solution of the utility model is: a kind of wireless data acquisition device with self-powered function, comprise current sensor, supply module and data transmission blocks, wherein: current sensor sends the current data of Real-time Collection to data transmission blocks, the induction coil of supply module sends induction electric energy to supply module, and supply module provides power supply for data transmission blocks.
Compared with prior art, the utility model has the advantages that: by the induction energy supply method, solved the powerup issue that is installed on the various data acquisition equipment on high-tension line, make the power supply of data acquisition equipment be no longer dependent on externally fed, but obtain by transmission line electric current self-induction, reliability is high; And this power supply not only can satisfy enough driving forces are arranged under little current conditions, can also guarantee that in large electric current, short circuit current and thunderbolt situation, wireless data acquisition device is not destroyed simultaneously; By taking necessary insulation blocking means; with the low-pressure side insulation processing; prevent device damage; improve the reliability of device: be that loop, the chip of shell structure design, material selection or the interiors of products of product, the design of components and parts are all to have adopted outdoor design; wide temperature environment; moistureproof, anti-high temperature, winter protection, electromagnetic induction, temperature sensitive member all by the photoelectric technology design, are prevented electromagnetic interference, good insulating effect.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 structural representation of the present utility model;
The structural representation of Fig. 2 supply module of the present utility model.
Embodiment
A kind of wireless data acquisition device with self-powered function as shown in Figure 1 and Figure 2, comprises current sensor 1, supply module 2 and data transmission blocks 3 etc., wherein:
Current sensor 1 Real-time Collection current data also sends current data to data transmission blocks 3.The induction coil of supply module is used for from the high-tension line induced current, and sends induction electric energy to supply module 2.
Supply module 2 comprises commutating circuit 4, filter circuit 5 and the loop of voltage regulation 6 that connects successively, is used to data transmission blocks 3 that uninterrupted, stable working power is provided.
Be embedded with the GSM/GPRS module in data transmission blocks 3, also can support DEGE CDMA the 3G transmission means, be used for the data that current sensor 1 gathers are outwards sent, the GSM/GPRS module is the micro power consumption wireless transceiver module.
Current sensor 1 adopts the punching mode to be installed on the insulator branch road of ultra-high-tension power transmission line with the induction coil that supply module 2 shares, rubber blanket side mounted outdoor special use in coil, fire-retardant, etch-proof, carry out fastening to coil, guarantee that wireless data acquisition device can be in the situation that do not need manual intervention, operation steadily in the long term.
Data transmission blocks 3 is connected with current sensor 1 by wire, supply module 2 and data transmission blocks 3 are packaged as a whole, be arranged separately on high-tension line, be connected by wire between data transmission blocks 3 and current sensor 1, form the split type wireless data acquisition device that is arranged on high-tension line.
Because the current peak on ultra-high-tension power transmission line and valley differ greatly, according to the approximation relation formula of induced voltage U w and the primary current Ip of coil: Uw=W
2A μ Ip ω/l, wherein W is coil turn, A is area of core section, l is core length, and μ is magnetic permeability, and ω is frequency, hour Uw is also less as Ip, so that the secondary side output current is not enough to drive load, and the secondary side output current causes too greatly the damage of load when Ip is very large.For avoiding the problems referred to above, the power supply magnetic core adopts the current transformer nanocrystalline magnet core, because nanocrystalline magnet core has relatively high permeability and relatively low saturation induction density, guaranteed that wireless data acquisition device has enough current drives loads when the ultra-high-tension power transmission line electric current is low, output current enters saturation condition when the transmission line electric current is very high no longer increases, and has solved well the problems referred to above.
