Abstract
The utility model discloses an intelligent switch room environment monitoring system based on a principle of double-beam infrared absorption. A monitoring host is respectively connected with a double-beam infrared SF6 sensor module, a 02 sensor module and a temperature/humidity module through a RS485 bus, is connected with a background computer through another RS485 bus, and is also respectively connected with an audible and visual alarm and a voice alarm. By adopting the system, the real-time concentration of SF6 in a switch room can be truly and accurately measured, and remote data transmission can be achieved. The system is particularly suitable for online monitoring of the SF6 switch room environment and can achieve intelligent requirements of equipment.
Description
Technical field
The utility model relates to a kind of switch gear room ambient intelligence supervisory system.
Background technology
When using with SF6 gas serves as that the cubicle switch of insulation and arc-extinguishing medium is when in use leaking, SF6 gas that leaks out and analyte thereof can gather toward indoor low layer space, and be difficult for distributing, cause local anoxic and band poison, to the maintenance in the inlet chamber and the personnel's of tour safety formation grave danger.
At present, the switch gear room's environmental monitoring system on the market has two big shortcomings.One: mostly use halogen sensor TGS832 and T6S830 to detect SF6 gas, do not stablize because SF6 does not belong to scope and the SF6 chemical property of R-113, R-22, R-11, R-12, R134a, it is impracticable that experiment confirm adopts this type of sensor SF6.Its two: system can't communicate by letter with background computer, and the user can't understand switch gear room's environmental aspect at Central Control Room.
Summary of the invention
For solving the problems referred to above that existing switch gear room environmental monitoring system exists, the utility model provides a kind of switch gear room's ambient intelligence supervisory system based on the twin-beam infrared absorption principle, and its technical scheme of taking is:
This system comprises monitoring host computer, twin-beam infrared ray SF6 sensor assembly, 02 sensor assembly, humiture module, audible-visual annunciator, phonetic alarm, blower fan and background computer, it is characterized in that: monitoring host computer connects twin-beam infrared ray SF6 sensor assembly, 02 sensor assembly and humiture module respectively by a RS485 bus, monitoring host computer connects background computer by another RS485 bus, and monitoring host computer connects audible-visual annunciator and phonetic alarm respectively simultaneously.Background computer can be replaced by switch gear room's environmental monitoring IED device.
This system selects the SF6 intelligent sensing module and 02 sensing module of twin-beam infrared absorption principle for use, accuracy of detection is up to ± 2%FS, response time was less than 5 seconds, life-span was greater than 10 years, two communication port of monitoring host computer design, a communication port links to each other with each intelligence sensor module, and multipotency is monitored the humiture of 64 points simultaneously, or 02, the SF6 gas concentration.Another communication port and background computer (or with switch gear room's environmental monitoring IED device) link to each other, but background computer real time monitoring switch indoor temperature, humidity, 02 concentration, SF6 concentration information, independently carry out the background computer monitoring or, carry out data transmission such as switch indoor temperature, humidity, 02 concentration, SF6 concentration, fan condition with IEC61850 (DL860) agreement according to according to the intelligent grid requirement.
Can be the truly accurate measuring switch indoor SF6 gas real-time concentration of this system is also realized data remote, is particularly suitable for the on-line monitoring of SF6 switch gear room environment, to reach the requirement of device intelligenceization.
Description of drawings
Accompanying drawing is a structured flowchart of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in the figure, monitoring host computer 1 main control chip is selected STC90C58AD for use, monitoring host computer 1 master connects twin-beam infrared ray SF6 sensor assembly 2,02 sensor assembly 3 and humiture module 4 by a RS485 bus respectively after photoelectricity is isolated, monitoring host computer 1 connects background computer 8 or switch gear room's environmental monitoring IED device by another RS485 bus after photoelectricity is isolated, monitoring host computer 1 connects audible-visual annunciator 5 and phonetic alarm 6 and blower fan 7 respectively simultaneously.
Each module sends to monitoring host computer 1 by the RS485 bus with temperature, humidity, 02 concentration, the SF6 concentration that collects, monitoring host computer 1 can be excessive at ambient humidity, 02 content is crossed low or during the SF6 content overproof, guide sound light crossing-signal 5 and phonetic alarm 6 send acousto-optic and audio alert signal respectively, and start blower fan 7 automatically and ventilate, monitoring host computer 1 is connected with background computer 8 by another RS-485 communication port, but background computer 8 real time monitoring switch indoor temperatures, humidity, 02 concentration, SF6 concentration.
