Abstract
The utility model discloses an SF6 gas leakage monitoring alarm system which comprises a transducer used for collecting data and a data processing unit used for processing data; the data processing unit is connected with monitoring alarm equipment; the transducer comprises a detection sensor used for detecting whether SF6 gas leaks or not, and a calibration sensor which is controlled to start when the detection sensor detects that SF6 gas leaks; the detection sensor and the calibration sensor are both in is signal connection with the data processing unit; and the data processing unit controls the monitoring alarm equipment to send out an SF6 gas leakage alarm signal when receiving SF6 gas leakage signals sent by the detection sensor and the calibration sensor. The detection sensor is corrected according to data of the calibration sensor. The sensors provided by the utility model have the advantages of long service life, reliability of detection, and capability of preventing misinformation effectively.
Description
Technical field
The utility model relates to monitoring alarm device, especially a kind of SF
6Gas leak supervision warning system.
Background technology
Electrion process detects SF
6, adopt two detecting electrodes, between two detecting electrodes, apply a constant voltage, just can puncture air, and between two electrodes, keep certain electric current, in air, there is SF
6The time, because SF
6Be a kind of insulating gas, it can make, and electric current reduces between electrode, by measuring this size of current, and and SF
6Leakage value compares demarcation, just can learn SF
6Leakage whether exceed standard.But electric field interference sometimes or other factors can influence the size of current between the electrode, cause the wrong report phenomenon easily.In addition, when long-play, the problem that loss is big during the ubiquity working sensor, serviceable life is short.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of depletion sensor little, the effectively anti-SF that reports by mistake
6Gas leak supervision warning system.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of SF
6Gas leak supervision warning system has the transmitter that is used for image data and the data processing unit of deal with data, and described data processing unit is connected with monitoring alarm equipment, and described transmitter has: be used to detect SF
6The detecting sensor whether gas leaks, detect SF by detecting sensor
6The calibrating sensors that control started when gas leaked, detecting sensor all is connected with the data processing unit signal with calibrating sensors, and data processing unit is receiving the SF that detecting sensor and calibrating sensors send
6Control monitoring alarm equipment sends SF during the gas leakage signal
6Gas leakage alarm signal.
Described calibrating sensors is not worked at ordinary times, has only the time service about month once or by detecting sensor control to start.
The beneficial effects of the utility model are: when detecting sensor is found SF
6When gas leaks, start calibrating sensors work immediately, have only when calibrating sensors and also find SF
6When gas leaked, data processing unit just can be controlled monitoring alarm equipment and send SF
6Gas leakage alarm signal prevents to disturb because of electric field sometimes or other reasons causes wrong report.
Simultaneously, calibrating sensors is not worked at ordinary times, has only the time service about month once or by detecting sensor control to start, and revises detecting sensor according to the data of calibrating sensors, thereby has reduced depletion sensor, has improved the serviceable life of sensor.Therefore, sensor long service life of the present utility model, detect reliable, can effectively prevent reporting by mistake.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments.
Fig. 1 is a structural representation of the present utility model;
Wherein: 1, data processing unit, 2, monitoring alarm equipment, 3, detecting sensor, 4, calibrating sensors.
Embodiment.
In conjunction with the accompanying drawings the utility model is further described now.The synoptic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
SF as shown in Figure 1
6Gas leak supervision warning system has the transmitter that is used for image data and the data processing unit 1 of deal with data, and data processing unit 1 is connected with monitoring alarm equipment 2, and transmitter has: be used to detect SF
6The detecting sensor 3 whether gas leaks, detect SF by detecting sensor 3
6The calibrating sensors 4 that control started when gas leaked, detecting sensor 3 all is connected with data processing unit 1 signal with calibrating sensors 4, and data processing unit 1 is receiving the SF that detecting sensor 3 and calibrating sensors 4 send
6Control monitoring alarm equipment 2 sends SF during the gas leakage signal
6Gas leakage alarm signal.
Calibrating sensors 4 is not worked when flat, has only the time service about month once or by detecting sensor 3 controls to start.
When detecting sensor 3 is found SF
6When gas leaks, start calibrating sensors 4 work immediately, have only when calibrating sensors 4 and also find SF
6When gas leaked, data processing unit 1 just can be controlled monitoring alarm equipment 2 and send SF
6Gas leakage alarm signal prevents to disturb because of electric field sometimes or other reasons causes wrong report.
Simultaneously, calibrating sensors 4 is not worked when flat, has only the time service about month once or by detecting sensor 3 controls to start, and revises detecting sensor 3 according to the data of calibrating sensors 4, thereby reduced depletion sensor, improved the serviceable life of sensor.Therefore, sensor long service life of the present utility model, detect reliable, can effectively prevent reporting by mistake.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the instructions, must determine its technical scope according to the claim scope.
