The system has the advantages of favorable real-time property, high reliability and flexibility in deployment; and false action generated by interference of a field electromagnetic signal can be avoided; the automatic and intelligent control is realized; and the labor intensity of a detector is reduced.
Description
Technical field
The present invention relates to a kind of system, especially relate to a kind of system that is used for the earth-fault indicator remote monitoring.
Background technology
In the looped network distribution system; Particularly use in the system of ring net load switch in a large number; If in the next stage distribution network system short trouble or earth fault have taken place, the electric power system of upper level must be carried out disjunction in official hour, to prevent major accident.So in system, earth-fault indicator must be installed.Earth-fault indicator is the equipment that is used for detecting short circuit and earth fault.Readout instrument is contained in the plastic casing; Is furnished with the LED lamp indication of time reset circuit and assignment circuit ground fault in the readout instrument by a flash of light; Short trouble on every cable by the LED lamp of a flash of light refer to readout instrument be furnished with each sensor of test/reset button by plastic casing with detect short circuit and earth fault and cause that the coil of pulse current forms; The version different according to sensor; Connect lead or be fixed on the sensor; Or by optical fiber grafting sensor, shell adopts injection mo(u)lding and satisfies the IP service condition.Meet or exceed ground current and start when reporting to the police not enough definite value (this value can according to setting an optimal value) when grounding sensor detects in the ground path electric current in actual operation parameters; Sent alerting signal; After main frame receives this signal, produce corresponding AIS (pilot lamp quickflashing).Because equipment sometimes is in the place operation that manual work is not easy to arrive; Inconvenient to equipment testing; Tradition adopts artificial mode can not satisfy actual use; And equipment is in operational process; Tradition adopts manually, and transmission manner just has certain fault rate; And transmission course is very long; Real-time is poor; Cause the treatment effeciency of burst accident also low; Cause a lot of troubles easily; While transmission has manually also increased labor intensity of operating personnel, and it is high to detect the expense that produces, and is unfavorable for quick, stable, the operation constantly of system.
Summary of the invention
The objective of the invention is to overcome the shortcoming and defect of above-mentioned prior art; A kind of system that is used for the earth-fault indicator remote monitoring is provided; This system real time is good; High reliability; Dispose flexibly; Can avoid disturbing the generation misoperation, realize robotization, intelligent control, reduce testing staff's labour intensity because of on-the-spot electromagnetic signal.
The object of the invention is realized through following technical proposals: be used for the system of earth-fault indicator remote monitoring, comprise GPRS communication terminal and the some earth-fault indicators that are connected with the GPRS communication terminal.
Be provided with signaling interface on the said earth-fault indicator, said GPRS communication terminal connects with corresponding earth-fault indicator through signaling interface.
Said GPRS communication terminal is connected with watch-dog.Through watch-dog the fault that earth-fault indicator indicates is carried out discriminatory analysis, handled easily personnel repair.
Said GPRS communication terminal is outside equipped with solar panel.
Said solar panel is arranged on two relative sides of GPRS communication terminal outer wall.Guarantee that solar panel is longer with contact area, the duration of contact of sunlight.
Said solar panel and inclined are 30 ° to 60 ° angle.
Said solar panel and inclined are 45 ° angle.Make solar panel to touch to maximum area sunlight, higher to the sunlight utilization factor.
In sum, the invention has the beneficial effects as follows: this system real time is good, and high reliability is disposed flexibly, can avoid disturbing the generation misoperation because of on-the-spot electromagnetic signal, has realized robotization, intelligent control, has reduced testing staff's labour intensity.
Description of drawings
Fig. 1 is a fundamental diagram of the present invention;
Fig. 2 is the scheme of installation of solar panel.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is done further detailed description, but embodiment of the present invention is not limited only to this.
Embodiment:
The system that is used for the earth-fault indicator remote monitoring as shown in Figure 1 comprises GPRS communication terminal and the some earth-fault indicators that are connected with the GPRS communication terminal.The GPRS communication terminal is in holding state at ordinary times, in case receive the alarm signal that earth-fault indicator sends, can send signal with SMS or GPRS mode to watch-dog immediately.
Be provided with signaling interface on the said earth-fault indicator, said GPRS communication terminal connects with corresponding earth-fault indicator through signaling interface.The GPRS communication terminal is connected on the signaling interface of earth-fault indicator, and when earth-fault indicator outputting alarm signal (opening or closing), the GPRS communication terminal sends to watch-dog to the signal that receives, and makes things convenient for the monitor staff to take measures to handle.
Said GPRS communication terminal is connected with watch-dog.The GPRS communication terminal works in holding state at ordinary times, can receive the signal that a plurality of earth-fault indicators change, and when the GPRS communication terminal receives the signal of a plurality of earth-fault indicators, sends to watch-dog through GPRS or SMS mode.
As shown in Figure 2, said GPRS communication terminal 1 is outside equipped with solar panel 2.GPRS communication terminal 1 adopts sun power to add the accumulator mode and supplies power.Solar panel 2 is arranged on GPRS communication terminal 1 outside, and when the electric weight deficiency of accumulator, solar panel 2 can guarantee that GPRS communication terminal 1 works on, and avoids detecting the accident of interrupting and causing taking place.
Said solar panel 2 is arranged on two relative sides of GPRS communication terminal 2 outer walls.Solar panel 2 is arranged on the outer wall side of GPRS communication terminal 1, has guaranteed that solar cell 2 plates to the making full use of of sunlight, have improved the efficient of charging.
Said solar panel 2 is 30 ° to 60 ° angle with inclined.Installation is adjusted according to actual use in concrete angle of inclination, guarantees the area maximization that solar panel 2 contacts with sunlight, and is more abundant to the utilization factor of sunlight.
Said solar panel 2 is 45 ° angle with inclined.Solar panel 2 settings are 45 ° angle, and time, the area that can make solar panel 2 contact with sunlight are all more abundant, the better effects if of charging.
High reliability of the present invention supports the frequency hopping mode to work, and data encryption mechanism, avoids disturbing the generation misoperation because of on-the-spot electromagnetic signal.
Take aforesaid way, just can realize the present invention preferably.
