Abstract
The utility model discloses a novel comprehensive monitoring system of a transformer station, which comprises an uninterrupted power supply unit, a flame sensor, a sulfur hexafluoride (SF6) gas sensor, an oxygen sensor, an anti-theft sensor, a transformer over temperature sensor and a cable over temperature sensor. All the sensors are respectively connected with a signal transmitting unit; the signal transmitting unit is connected with an operational amplifier; then the operational amplifier is connected with a digital signal processor (DSP)2812 main controller through an amplitude limiting circuit unit; and the DSP2812 main controller is respectively connected with a random-access memory (RAM) storage unit, a digital/analog (D/A) converting unit, a display unit, a fan control unit and a general packet radio service (GPRS) radio receiving unit. The novel comprehensive monitoring system of the transformer station monitors a plurality of items, greatly improves the daily maintenance efficiency of the transformer station, and has excellent detection effect and high stability.
Description
Technical field
The utility model relates to the monitoring field, especially a kind of novel integrated substation supervisory control system.
Background technology
The quantity of substation in zone increases suddenly in the city at present, and the position of these electric substations comparatively disperses, and daily operation management is inconvenience very, also has a large amount of security hidden troubles simultaneously, such as:
1, be subjected to factor affecting such as temperature, ageing equipment, the transformer cable of substation in zone etc. usually can burn because of superhigh temperature, causes the power failure phenomenon;
2, the personnel that keep an eye on of substation in zone, each make an inspection tour between the time interval often longer, when breaking out of fire or when artificially damaging, all can not be found in the very first time, rectify.
The utility model content
The utility model technical assignment is at not enough in the above-mentioned technology, and a kind of novel integrated substation supervisory control system is provided.
The utility model technical solution technical scheme that problem adopts is: novel integrated substation supervisory control system, comprise the uninterrupted power supply unit, flame sensor, the SF6 gas sensor, oxygen sensor, theft-proof sensor, transformer over-temperature sensor and cable over-temperature sensor, described flame sensor, the SF6 gas sensor, oxygen sensor, theft-proof sensor, the transformer over-temperature sensor is connected with signal transmission unit respectively with the cable over-temperature sensor, signal transmission unit links to each other with operational amplifier, operational amplifier is connected with the DSP2812 master controller by the amplitude limiter circuit unit then, described DSP2812 master controller respectively with ram memory cell, the D/A converting unit, display unit, blower fan control unit and GPRS radio receiving unit link to each other.
Described D/A converting unit links to each other with voice module, and described GPRS radio receiving unit links to each other with mobile phone or host computer.
The beneficial effect that the utility model can bring is:
(1) monitoring project is many, and it is excellent to detect effect, and stability is high.
(2) improved the regular maintenance efficient of electric substation greatly.
Description of drawings
Fig. 1, fundamental diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done following detailed description:
As shown in Figure 1, novel integrated substation supervisory control system, comprise the uninterrupted power supply unit, flame sensor, the SF6 gas sensor, oxygen sensor, theft-proof sensor, transformer over-temperature sensor and cable over-temperature sensor, described flame sensor, the SF6 gas sensor, oxygen sensor, theft-proof sensor, the transformer over-temperature sensor is connected with signal transmission unit respectively with the cable over-temperature sensor, signal transmission unit links to each other with operational amplifier, operational amplifier is connected with the DSP2812 master controller by the amplitude limiter circuit unit then, described DSP2812 master controller respectively with ram memory cell, the D/A converting unit, display unit, blower fan control unit and GPRS radio receiving unit link to each other.Described D/A converting unit links to each other with voice module, and described GPRS radio receiving unit links to each other with mobile phone or host computer.
The uninterrupted power supply unit is to flame sensor, SF6 gas sensor, oxygen sensor, theft-proof sensor, transformer over-temperature sensor, cable over-temperature sensor, signal transmission unit connection, operational amplifier, amplitude limiter circuit unit, DSP2812 master controller, ram memory cell, D/A converting unit, voice module, display unit, blower fan control unit and GPRS radio receiving unit and mobile phone or host computer centrally connected power supply.
During concrete the use, all the sensors obtains the analog signal of standard through signal transmission unit, this analog signal is amplified through operational amplifier, isolate, feed amplitude limiter circuit again and enter advanced DSP2812 master controller, after the processing of DSP2812 master controller, be sent to ram memory cell respectively and carry out storage; Be sent to the D/A converting unit, voice module converts audio signal to; Be sent to display unit and convert vision signal to; Convert active contact control signal at the blower fan control unit; Be transported at the GPRS radio receiving unit and export mobile phone or host computer to the wireless data form; Host computer also can carry out remote control with the comprehensive monitoring system that control command is delivered to each substation in zone by GPRS wireless data form simultaneously.
The utility model monitoring project is many, and it is excellent to detect effect, and stability is high, has improved the regular maintenance efficient of electric substation greatly.
