Description
Technical field
The utility model relates to distribution network technology field, particularly relates to a kind of fault detector power supply with wireless communication module.
Background technology
Along with more and more higher to the requirement of power distribution network safe operation, the Real-Time Monitoring of power distribution network receives on-the-spot concern day by day.At present, China major part Medial & Low Voltage Power Network, particularly 10KV distribution network, operation and management level, monitoring means are lower; Mainly because 10KV distribution network circuit is long, wide coverage, if install the monitoring and scheduling automated system based on RTU as power transmission network, its cost will be unaffordable; And the power distribution network part that to be also power system accident multiple, the ground connection of more than 90% or short trouble occur in power distribution network; Carrying out fault location isolated fault section when breaking down in time, recovering the power supply of regular link section, most important to power distribution network safe operation.Power distribution network ground connection and short trouble be positioned with a lot of method, method hangs conventional fault indicating device along circuit more accurately at present, and the fault detector when a failure occurs it on fault point power supply survey line road turns over red; When the staff of transformer station finds that there is fault, check fault detector state along circuit, thus the localization of faults; Although this conventional fault indicating device more accurately can indicate fault section, but need staff to check indicating device board turning state along the line, labor strength is comparatively large, especially for the distribution line in some mountain areas, checks that indicator status is a thing of working hard very much along the line.
Based on more than, the power supply mould with wireless communication module is set up in this case, be conducive to making system, by the mode of radio communication, malfunction be sent to neighbouring data receiving terminal, line fault information is sent to Surveillance center by GPRS networking mode by this data terminal in time.Therefore, for above aspect, need reasonably to improve prior art.
Utility model content
For above defect, the utility model provides a kind of can improve the time shortening fault restoration and the labour intensity reducing workman greatly, be conducive to measurement circuitry normal duty electric current and line temperature, automatic management level that long time stability ran, can greatly improve distribution network, alleviate the labour intensity of workman, improve the fault detector power supply with wireless communication module of operation of power networks reliability, to solve many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
A kind of fault detector power supply with wireless communication module, comprise power module, described power module is inner with an electric energy input inductance coil, the branch road of electric energy input inductance coil opposite side installs one and prevents reverse charge diode, this prevents from reverse charge diode and battery from inputting protection module connecting;
Described electric energy input inductance coil accesses NRF24L01 chip with end and this chip other end is connected and prevents reverse charge diode.
The beneficial effect with the fault detector power supply of wireless communication module described in the utility model is:
(1) power module is with wireless communication module, for completing wireless transmission and reception, because fault detector and data receiving terminal spacing are less than 10m, so transmission range does not require far, the 2.4GHz wireless communication module of core that what this device was selected with NRF24L01 is, this module antenna is just made on pcb board, volume is little, low in energy consumption, be particularly suitable for embedded system to use, this module work voltage is 1.9V ~ 3.6V, adopt two I/O pins of single-chip microcomputer to wireless communication module power supply in this device, to realize without in communicating requirement situation, wireless communication module power consumption is 0, be conducive to accurate measurements line-to-ground and short trouble, there is the function of measurement circuitry normal duty electric current and line temperature, and by radio communication, these monitoring informations are sent out,
(2) by adopting comprehensive hardware anti-interference circuit and Software Anti-interference algorithm, ensure that this device can run by long time stability under adverse circumstances at the scene, this multi-functional fault detector is applied to power distribution network, greatly can improve the automatic management level of distribution network, alleviate the labour intensity of workman, improve the reliability of operation of power networks.
Accompanying drawing explanation
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the power module schematic diagram of the fault detector power supply described in the utility model embodiment with wireless communication module.
In figure:
21, electric energy input inductance coil; 22, reverse charge diode is prevented; 23, battery input protection module; 24, NRF24L01 chip.
Embodiment
As shown in Figure 1, the fault detector power supply with wireless communication module described in the utility model embodiment, described power module 3 inside is with an electric energy input inductance coil 21, the branch road of electric energy input inductance coil 21 opposite side is installed one be made up of D2 prevent reverse charge diode 22, this prevents from reverse charge diode 22 from inputting protection module 23 with the battery be made up of D1, R1 connecting; Described electric energy input inductance coil 21 accesses NRF24L01 chip 24 with end and this chip other end is connected and prevents reverse charge diode 22.L1 is the inductance coil obtaining electric energy from circuit, and in the standby state, when line current is more than 20A, induction coil output voltage exceedes cell voltage after rectification, hinders the output of battery current, can effectively conserve battery charge; When fault indicator is in measurement and wireless transmission state, operating current is comparatively large, and electric current provides primarily of 3.6V battery; The power supply of wireless transport module NRF24L01 is provided by the I/O pin of Atmega8L, and this single-chip processor i/o mouth maximum output current in 3V situation is 10mA, gets up to power to NRF24L01 can meet the job requirement of NRF24L01 completely with two I/O pins; Thermometric chip DS18B20 can directly be powered by VCC; In figure, L1 rectification uses 5.1V voltage stabilizing after exporting, and is to burn single-chip microcomputer to prevent producing too high voltages when line current is larger, and when D2 is to prevent line current large, induced voltage is to battery reverse charge; Voltage after inductance coil L1 exports rectification also detects for realizing line short, R1 and D1 in figure is to prevent the output of battery from impacting line short test section.
The above-mentioned description to embodiment can understand and apply this case technology for the ease of those skilled in the art, person skilled in the art obviously can make various amendment to these examples easily, and General Principle described herein is applied in other embodiment and need not through performing creative labour.Therefore, this case is not limited to above embodiment, and those skilled in the art is according to the announcement of this case, and the improvement made for this case and amendment all should in the protection ranges of this case.
