Description
Technical field
The utility model relates to a kind of gas leakage monitoring warning device, particularly a kind of sulfur hexafluoride gas leakage monitoring warning device.
Background technology
Sulfur hexafluoride gas has desirable insulating property and arc extinction performance, has been widely used in the various high-tension switch gears.But because factors such as mass discrepancy such as manufacturings, installation and material agings, cause the problem of sulfur hexafluoride equipment generation gas leakage easily, this also is a ubiquitous phenomenon.According to China Electric Power Research Institute statistics, nineteen ninety to 1997 a year domestic high-tension switch gear break down altogether 1500 times, took place altogether 2412 times in 1997 to 2004, one of these cause faults occurring is exactly that sulfur hexafluoride gas leaks.In a single day sulfur hexafluoride gas leaks, will bring serious hidden danger to the safe operation of power equipment and office work personnel's life security.Therefore, realize that on-line monitoring, Realtime Alerts, on-the-spot processing automatically and Ventilation Control to the switch indoor environment are the most important things.But the single detection to sulfur hexafluoride gas can not be contained the demand of safety in production fully, if can design the monitoring equipment of a multiple spot, many gaseous species, believes to meet current actual demand.
Summary of the invention
The purpose of the utility model just is to provide a kind of sulfur hexafluoride gas leakage monitoring warning device, can address the above problem fully.
To achieve these goals; The technical scheme that the utility model adopts is such: the sulfur hexafluoride gas leakage monitoring warning device of the utility model; Comprise transmitter, system host and peripherals; Transmitter links to each other through fieldbus with system host; Transmitter comprises sulfur hexafluoride sensor, lambda sensor, temperature sensor and humidity sensor, and system host is a main control unit, and peripherals comprises ventilation blower, central signal system and supervisory system; Sulfur hexafluoride sensor output terminal, lambda sensor output terminal, temperature sensor output terminal and humidity sensor output terminal link to each other with the main control unit input end through the A/D conversion respectively, and the main control unit output terminal links to each other with ventilation blower input end, central signal system input and supervisory system input end respectively.
Compared with prior art, the advantage of the utility model is: the sulfur hexafluoride gas leakage monitoring warning device of the utility model, can carry out comprehensive monitoring to a zone; Has multiple measuring ability; And can in time carry out onsite alarming, and making things convenient for on-call maintenance, alarm set point can be set up on their own by the user simultaneously; Bus and networking context of detection have rational improvement at the scene in addition, have improved the reliability that detects to a certain extent greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
To combine accompanying drawing that the utility model is described further below.
Referring to Fig. 1; The sulfur hexafluoride gas leakage monitoring warning device of the utility model; Comprise transmitter, system host and peripherals; Transmitter links to each other through fieldbus with system host; Transmitter comprises sulfur hexafluoride sensor, lambda sensor, temperature sensor and humidity sensor, and system host is a main control unit, and peripherals comprises ventilation blower, central signal system and supervisory system; Sulfur hexafluoride sensor output terminal, lambda sensor output terminal, temperature sensor output terminal and humidity sensor output terminal link to each other with the main control unit input end through the A/D conversion respectively, and the main control unit output terminal links to each other with ventilation blower input end, central signal system input and supervisory system input end respectively.
The utlity model has multiple measuring ability, can not only detect, and can also detect temperature and humidity environmental data index to sulfur hexafluoride gas and carrier of oxygen content; And fieldbus is a cable, and a cable can connect all transmitters and system host, can be discrete capable of being combined; Have very high on-the-spot adaptability, do not limit the monitoring point in addition, can detect a plurality of monitoring points simultaneously; Satisfy the large construction project needs, strengthened detecting reliability to a certain extent.When operation the utility model, through transmitter the transmitter site environment is carried out data acquisition earlier, carry out the A/D conversion again and send main control unit to, main control unit is analyzed, is compared and judge image data again, and moves corresponding handling procedure.When sulfur hexafluoride gas concentration in the environment or oxygen content change; The sulfur hexafluoride gas transmitter can capture this variation at once; And the data-switching that will detect variation becomes digital signal; Send main control unit to through on-the-spot main line, the image data that main control unit sends transmitter on the one hand shows on display screen; On the other hand,, carry out corresponding comparison with various preset parameters on the storer that is stored in the main frame, and make judgement, see whether each association exceeds standard through operational analysis.When concentration of sulfur hexafluoride is higher than alarm setting value (being generally 1000ppm) or oxygen content and is lower than alarm setting value 18%; Main control unit will carry out acousto-optic, audio alert automatically; Starting blower fan simultaneously ventilates; The central signal system uploads its alerting signal then, finally realizes reliable monitoring, alarming function.
