Description
Technical field
The utility model relates to a kind of device for testing smell, relates in particular to the equipment heating fault smell on-Line Monitor Device for detection of electronic component in switch cubicle.
Background technology
The product that in domestic existing switch cubicle, equipment heating detects is a lot, has the various ways such as wireless temperature measurement, optical fiber temperature-measurement, is all to adopt temperature-sensing probe directly to gather after heating position temperature, uploads, and all belongs to physics acquisition mode.Equipment in switch cubicle, can produce various smells when especially heating accident appears in part secondary device, and the at present domestic method that adopts smell collection and analysis that there is no carrys out the heating accident of detector switch internal unit with chemical mode.And in the gas that equipment produces, contain a large amount of objectionable impuritiess, if cabinet is opened in the monitoring of the indexs such as the corresponding gas concentration of nothing rashly, can produce harm to operating personnel.Meanwhile, malfunctioning because of special circumstances when monitoring equipment, after switch in-cabinet temperature is raise, in switch cubicle, easily produce naked light, initiation fire.
Summary of the invention
The purpose of this utility model is to provide a kind of and changes by switch cubicle composition of gases within, the equipment heating fault smell on-Line Monitor Device that can monitor device temperature in switch cubicle.
The purpose of this utility model is achieved in that equipment heating fault smell on-Line Monitor Device, it is by gas generating unit, in order to the temperature sensor of monitor temperature, in order to the gas sensor of gas-monitoring, and form in order to the single-chip microcomputer of data acquisition transmission.Described temperature sensor and gas sensor and single-chip microcomputer are installed in switch cubicle, three's circuit is connected, described gas generating unit comprises upper and lower raw material chamber and reaction chamber, upper and lower raw material chamber is communicated with reaction chamber by woven hose, reaction chamber place is communicated with gas outlet, and gas outlet outer end is positioned at outside gas generating unit, stretches in switch cubicle, on woven hose, be equiped with solenoid valve, solenoid valve is connected with single chip circuit.
Owing to carrying out technique scheme, the application, by the monitoring to gas in switch cubicle, reaches the object to machine operation monitoring, guaranteeing in switch cubicle in equipment stable operation, harm gas is control effectively simultaneously, and can prevent the spontaneous combustion of switch cubicle, harm is down to minimum.
Brief description of the drawings: the technical solution of the utility model is provided by following drawings and Examples:
Fig. 1 is equipment heating fault smell on-Line Monitor Device structural representation;
Fig. 2 is gas generating unit structural representation.
Legend: 1. gas sensor; 2. gas outlet; 3. temperature sensor; 4. single-chip microcomputer; 5. solenoid valve; 6. gas generating unit; 7. go up raw material chamber; 8. reaction chamber; 9. woven hose; 10. descend raw material chamber.
Embodiment:
The utility model is not subject to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment 1: as shown in Figure 1, 2, it is by gas generating unit 6 for equipment heating fault smell on-Line Monitor Device, in order to the temperature sensor 3 of monitor temperature, in order to the gas sensor 1 of gas-monitoring, and forms in order to the single-chip microcomputer 4 of data acquisition transmission.Described temperature sensor 3 and gas sensor 1 and single-chip microcomputer 4 are installed in switch cubicle, and three's circuit is connected.Described gas generating unit 6 comprises upper and lower raw material chamber 7,10 and reaction chamber 8, and upper and lower raw material chamber 7,10 is communicated with reaction chamber 8 by woven hose 9, and reaction chamber 8 places are communicated with gas outlet 2, and gas outlet 2 outer ends are positioned at outside gas generating unit 6, stretch in switch cubicle.On woven hose 9, be equiped with solenoid valve 5, solenoid valve 5 is connected with single-chip microcomputer 4 circuit.
The aforementioned upper raw material chamber 7 interior filling concentrated sulphuric acids, the interior filling sodium bicarbonate mixed liquor in lower raw material chamber 10, adopt the irreversible chemical reaction of strong acid and highly basic to produce C02 gas, because two kinds of reactant liquor reactions are violent, and reaction is thermonegative reaction, the process of release of carbon dioxide is endothermic process, so the gas temperature producing is low, pressure is high.Reaction equation is as follows: H2SO4+2NaHCO3 → Na2SO4+2CO2 ↑+2H2O.Can install small-sized infusion pump at woven hose 9 places pumps into reactant liquor in reaction chamber 8.
Described gas sensor 1, temperature sensor 3, solenoid valve 5 and small-sized infusion pump are market purchasing part.
When use, single-chip microcomputer 4 is connected with corresponding remote supervision system by communication network.When switch in-cabinet temperature raises, signal is sent to single-chip microcomputer 4 by temperature sensor 3, and transfer to remote supervision system.In the time that temperature rises to critical point, send and open valve instruction to single-chip microcomputer 4 by remote supervision system, single-chip microcomputer 4 is controlled solenoid valve 5 and is opened, and upper and lower raw material chamber 7,10 interior reactant liquors enter reaction chamber 8 and mix generation carbon dioxide, and are discharged by gas outlet 2.Gather the gas datas such as carbon dioxide by gas sensor 1 subsequently, and feed back to remote supervision system.Can effectively stop in switch cubicle by the discharge of carbon dioxide on fire, and gas, temperature data in pilot switch cabinet in real time.
Above technical characterictic has formed most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease according to actual needs inessential technical characterictic, meets the needs of different situations.
