The remote monitoring system is simple in structure and capable of rapidly detecting failures, labor intensity of operators is relieved, automated and intelligent control is realized, and the system is ensured to run rapidly, stably and continuously.
Description
Technical field
The utility model relates to detection system, especially relates to the earth-fault indicator remote supervision system.
Background technology
In the looped network distribution system course of work, 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 refers to that by the LED lamp of a flash of light readout instrument is furnished with each sensor of test/reset button by plastic casing with detect short circuit and earth fault causes 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 is in operational process, tradition adopts manually, and transmission manner just has certain fault rate, and transmission course is very long, cause the treatment effeciency of burst accident also low, cause a lot of troubles easily, transmission has also increased labor intensity of operating personnel manually simultaneously, detects the expense height that produces, and is unfavorable for quick, stable, the operation constantly of system.
The utility model content
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, a kind of earth-fault indicator remote supervision system is provided, this supervisory system is simple in structure, reduced labor intensity of operating personnel, robotization, intelligent control have been realized, can realize detection apace, quick, stable, the operation constantly of assurance system to fault.
The purpose of this utility model is achieved through the following technical solutions: the earth-fault indicator remote supervision system comprises local wireless transmitter and the GPRS communication terminal that is connected with the local wireless transmitter.
Described local wireless transmitter is connected with earth-fault indicator.
Described earth-fault indicator is provided with signaling interface, and described local wireless transmitter is connected with earth-fault indicator by signaling interface.
Described GPRS communication terminal is connected with watch-dog.By watch-dog the fault that earth-fault indicator indicates is carried out discriminatory analysis, handled easily personnel repair.
Described GPRS communication terminal is outside equipped with solar panel.Improve the working time of GPRS communication terminal.
Described 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.
Described solar panel and horizontal direction tilt to be 30 ° to 60 ° angle.
Described solar panel and horizontal direction tilt to be 40 ° angle.Make solar panel to touch to maximum area sunlight, higher to the sunlight utilization factor.
In sum, the beneficial effects of the utility model are: this supervisory system is simple in structure, has reduced labor intensity of operating personnel, has realized robotization, intelligent control, can realize detection apace, quick, stable, the operation constantly of assurance system to fault.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model;
Fig. 2 is the solar panel scheme of installation.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited only to this.
Embodiment:
Earth-fault indicator remote supervision system as shown in Figure 1 comprises local wireless transmitter and the GPRS communication terminal that is connected with the local wireless transmitter.The local wireless transmitter adopts the internal cell power supply, all be for holding state at ordinary times, with save power, only when the earth-fault indicator output signal changes, the local wireless transmitter starts to GPRS communication terminal emission data, so that take timely measure.
Described local wireless transmitter is connected with earth-fault indicator.Earth-fault indicator is provided with the value of warning when installing, and when parameter surpassed the value of setting, during earth-fault indicator outputting alarm signal (opening or closing), the local wireless transmitter transmitted to the GPRS communication terminal.
Described earth-fault indicator is provided with signaling interface, and described local wireless transmitter is connected with earth-fault indicator by signaling interface.The local wireless transmitter is connected on the signaling interface of earth-fault indicator, and the GPRS communication terminal sends to the mode of the alerting signal of collecting by GPRS or SMS on the watch-dog.
Described GPRS communication terminal is connected with watch-dog.Watch-dog receives the signal that the GPRS communication terminal feeds back, and handled easily personnel control in real time.Described watch-dog also can be taked intelligent control, configures program schema, when running into the situation of burst, takes to handle according to the program schema of setting, and the real-time height has been avoided manually-operated hysteresis quality.
As shown in Figure 2, described GPRS communication terminal 1 is outside equipped with solar panel 2.GPRS communication terminal 1 adopts sun power to add the accumulator mode and powers, work in holding state at ordinary times, can receive the wireless signal of a plurality of local wireless transmitters, when GPRS communication terminal 1 receives native wireless signals, send to watch-dog by GPRS or SMS mode.
Described solar panel 2 is arranged on two relative sides of GPRS communication terminal 1 outer wall.Solar panel 2 is arranged on the outer wall side of GPRS communication terminal 1, has guaranteed making full use of of 2 pairs of sunlight of solar panel, has improved the efficient of charging.
Described solar panel 2 tilts to be 30 ° to 60 ° angle with horizontal direction.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.
Described solar panel 2 tilts to be 40 ° angle with horizontal direction.Solar panel 2 settings are 40 ° angle, and time, the area that can make solar panel 2 contact with sunlight are all more abundant, the better effects if of charging.
Take aforesaid way, just can realize the utility model preferably.
