Background technology
Along with the national economy high speed development, every profession and trade is increasing to electricity needs, and the quality of power supply is had higher requirement, particularly along with under national intelligent grid construction demand, and special requirement transmission line energy safety, stable operation.Along with technical development with apply, the electric equipment (data acquisition equipment) that is operated on ultra-high-tension power transmission line is more and more, as filthy in high-tension insulator state on_line monitoring system, the anti-key electric installation of intelligence, power circuit on-line measuring device, line facility anti-theft device, inspection robot, hot line robot, the filthy on-line monitoring of high-tension line etc., because most transmission line is remote, be difficult to way solution power supply supply problem routinely, thereby the power supply of these data acquisition equipment is generally adopted solar energy or is charged and discharged accumulate pond power supply.Solar powered owing to being subjected to the effects limit such as energy conversion rate, climatic environment and cost, can't fully satisfy equipment to the requirement of round-the-clock and steady in a long-term energy supply aspect; And the accumulate pond life-span is low, and maintenance cost is high, realizes the on line real-time monitoring function thereby cause being difficult on ultra-high-tension power transmission line popularization.
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.
Also be provided with data storage and be connected with data transmission blocks 3, be used for save data.When line outage, wireless data acquisition device quits work, and due to the memory that the power down save data is arranged in device, after electric wire recovers power transmission, can easily data be read out from memory.
The normal power consumption of this wireless data acquisition device extremely low (being approximately about 3W) has enough driving forces under little current conditions.And by be provided with photoelectric isolating device on commutating circuit 4, filter circuit 5 and loop of voltage regulation 6, also guaranteed the photoelectric isolating device by installing in large electric current, short circuit current and thunderbolt situation, can guarantee that wireless data acquisition device is not destroyed.
Operation principle of the present utility model is: this power-supply system magnetic core directly is enclosed within on ultra-high-tension power transmission line, and high-tension current flows through transmission line can induce electric current for rear class at the secondary side of magnetic core, reach self-powered purpose.Because whole system hangs in high tension loop, system and low-pressure system be without any electrical connection, system and high voltage transmission line equipotential, the significant cost cost of therefore having avoided traditional high voltage test system must take complicated insulation measures to bring.
Second siding ring output is through adopting the stronger voltage stabilizing circuit of Absorption Current ability after bridge rectifier, guaranteed ultra-high-tension power transmission line in the situation that in short-term the overcurrent secondary side current absorbed by voltage stabilizing circuit, avoid causing the impact to rear class.
