Switch cubicle heating detection means commonly used is directly to carry out temperature detection at present, comprises contact temperature-measuring and contactless temperature-measuring.If the employing Non-contact Infrared Temperature Measurement, too many, the installation inconvenience of layouting.If the use contact type measurement need to be isolated transmission with optical cable, owing to contacting with high-tension apparatus, there is accident potential in temperature measuring equipment itself and can not covers the interior all devices of cabinet.How detector switch cabinet inner cable, cable end and other first and second apparatus overheat, and send in advance early warning signal, prevent because equipment heating causes security incident, be the electrical production problem that current urgent need solves.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of switch cubicle fault early warning system, layout in above-mentioned direct temperature measurement method for prior art many, install inconvenience, overlay device comprehensively and temperature measuring equipment itself have the defective of accident potential, a kind of not direct temperature measurement is provided, and realizes monitoring and the early warning of apparatus overheat fault by the particle concentration that equipment heating in the detector switch cabinet volatilizees.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of switch cubicle fault early warning system comprises for the unit 102 of bleeding that extracts switch cubicle 101 interior gases, the laser monitoring device 103 that is connected with the unit 102 of bleeding, for the background host computer 104 of obtaining laser monitoring device 103 Monitoring Data;
Offer the aperture of bleeding on described switch cubicle 101, the unit 102 of bleeding is connected with the aperture of bleeding on switch cubicle 101 by connecting tube 105;
One end of described laser monitoring device 103 is connected with the unit 102 of bleeding by connecting tube 105, and the other end is exported gas 106 by connecting tube 105.
Can volatilize particulate after equipment heating in switch cubicle 101, comprise the gas 106 of particulate by unit 102 extractions of bleeding, and be input in laser monitoring device 103.Due to an end of the laser monitoring device 103 input gas 106 that is connected with the unit 102 of bleeding, the other end is by connecting tube 105 output gases 106, just can monitor density of particle in the gas of interior process of unit interval.The data that laser monitoring device 103 will monitor density of particle again are sent to background host computer 104.Background host computer 104 draws according to the size of density of particle and whether has apparatus overheat in switch cubicle 101 and carry out fault pre-alarming.
Implement switch cubicle fault early warning system of the present utility model, has following beneficial effect: can realize the early monitoring early warning to apparatus overheat fault in switch cubicle, realize the covering of the overheated detection of all devices in switch cubicle by extracting gases, avoid installing temperature-detecting device in switch cubicle, be applicable to the switch cubicle of any type, larger using value is arranged in electrical production.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in accompanying drawing:
Fig. 1 is switch cubicle fault early warning system schematic diagram.
Embodiment
Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast accompanying drawing and describe embodiment of the present utility model in detail.
As shown in Figure 1, a kind of switch cubicle fault early warning system comprises for the unit 102 of bleeding that extracts switch cubicle 101 interior gases, the laser monitoring device 103 that is connected with the unit 102 of bleeding, for the background host computer 104 of obtaining laser monitoring device 103 Monitoring Data;
Correct position on switch cubicle 101 offers the aperture of bleeding, and the unit 102 of bleeding is connected with the aperture of bleeding on switch cubicle 101 by connecting tube 105, extracts the interior gas 106 of switch cubicle 101, and by connecting tube 105 with gas 106 input laser monitoring devices 103.Laser monitoring device 103 sends the data that monitor to background host computer 104, by the also early warning of realization to the switch cubicle fault of 104 pairs of described data analysis of background host computer.
One end of described laser monitoring device 103 is connected with the unit 102 of bleeding by connecting tube 105, and the other end is exported gas 106 by connecting tube 105.
In Fig. 1, the unit 102 of bleeding is an aspiration pump, and aspiration pump twenty four hours continuous operation ceaselessly will be input to from the gas 106 of switch cubicle 101 interior extractions laser monitoring device 103, and the other end of laser monitoring device 103 is with gas 106 outputs.Can guarantee that like this density of particle that monitors is the density of particle in the flowing gas of process in the unit interval and is real-time density of particle.
There are a light-emitting tube and a light receiving tube in laser monitoring device 103 inside, when gas process light-path, and the particulate that volatilizees if there is equipment heating in switch cubicle in gas, thus will have influence on the illumination realization of light receiving tube to the monitoring of density of particle.
The utility model adopts the laser monitoring technology, and the density of particle in the gas of switch cubicle extraction is monitored, and background host computer draws whether there is the equipment heating fault in switch cubicle to the density analysis of particulate in gas.Background host computer is sent fault pre-alarming according to density of particle can comprise following two schemes:
