Description of drawings
Fig. 1 is the structural drawing of this remote temperature image of substation monitoring system;
Fig. 2 is this remote temperature image of substation monitoring device scheme of installation.
Wherein: 1 is panorama monitoring thermal infrared imager, and 2 is the fixed point monitoring thermal infrared imager, and 3 is the mobile monitoring thermal infrared imager, and 4 is network interface, and 5 is transformer station.
Embodiment
As depicted in figs. 1 and 2, middle position in transformer station 5 is provided with two high-resolution panorama monitoring thermal infrared imagers 1, panorama monitoring thermal infrared imager is used for all general device except that main-transformer in the monitoring substation, and panorama monitoring thermal infrared imager is furnished with the The Cloud Terrace that can freely rotate in the visual angle of 360 degree; Panorama monitoring thermal infrared imager detects distance, and monitoring time is shorter, can't failure judgement reason and grade, in order to overcome this defective, when panorama monitoring thermal infrared imager detected fault, the 3 pairs of abort situation places of mobile monitoring thermal infrared imager that re-use intermediate resolution carried out the monitoring of one-period; Be provided with the fixed point monitoring thermal infrared imager 2 of two low resolution in the both sides, front and back of main-transformer, the fixed point monitoring thermal infrared imager also is furnished with The Cloud Terrace, makes it can monitor each position of main-transformer by rotation.Also be furnished with the identical visible light camera in visual angle and the temperature sensor and the humidity sensor that are used for surrounding being monitored on three kinds of thermal infrared imagers simultaneously, purpose is to be that more accurate correlation data is collected in monitoring.
Every monitoring thermal infrared imager is connected with data processing server by cable network, cable network used herein with optical fiber as medium, to avoid the influence of electromagnetic field; Network interface 4 is made of fiber optical transceiver and Fiber splice tray, is equipped with power supply on it.The periphery of each equipment will be provided with a network interface at least in transformer station, normally the outermost in the power station is provided with one at a certain distance, and network interface also is set at interval the row of adjacent two row's equipment and row's centre position, the purpose of doing like this is to make things convenient for mobile monitoring thermal infrared imager access network nearby, reduces to be exposed to ground lead; The I/O port of data processing server is connected with fiber optical transceiver, and data processing server also is connected with the disk array of mass memory, is convenient to staff's follow-up work; Data processing server connects monitoring terminal by the network switch, and terminal can be big screen display screen or the video wall that is connected in the LAN (Local Area Network), also can be the PC that has different control authorities in the wide area network.
When selecting panorama monitoring thermal infrared imager, the main factor of considering is the closeness of shooting clear degree, hardware cost and power transformation station equipment, its monitoring target comprises that joint area, the cable of lead are lifted one's head and tiny position such as porcelain pillar, should select the high thermal infrared imager of resolution.The equipment of the monitoring range of panorama monitoring thermal infrared imager in will covering transformer station as much as possible; so common meeting spacious relatively place in transformer station is provided with this thermal imaging system converting equipment is carried out remote monitoring; consider the size and the dense degree of hardware cost and monitored site again; need select the high-resolution thermal infrared imager of resolution more than or equal to 480 * 480pixel for use, general resolution is that 640 * 480pixel just can satisfy the demands.The thermal infrared imager of 640 * 480pixel can be observed in the distance of 30 meters of radiuses and know that diameter is two centimetres a object, two centimetres of diameters of a screw cap just.
When selecting the fixed point monitoring thermal infrared imager, because the fixed point monitoring thermal infrared imager is only monitored main-transformer a set of equipment, and be both direction closely monitoring simultaneously, the main-transformer volume ratio is bigger in addition, resolution just can meet the demands smaller or equal to the low resolution thermal infrared imager of 160 * 160pixel, and generally selecting resolution for use is being advisable of 160 * 120pixel.
The mobile monitoring thermal infrared imager is the monitoring equipment that cooperates panorama monitoring thermal infrared imager to use, its monitoring objective is that panorama monitoring thermal infrared imager is found but can't be judged the position of concrete failure cause, these positions all are the contact point that is on the elevated line mostly, monitoring distance is far away and volume is very little, the thermal imaging system that resolution is too low is difficult for observation, and Tai Gao can cause certain wasting of resources, so use resolution to get final product at the thermal infrared imager of the intermediate resolution of 160 * 160pixel to 480 * 480pixel, generally selecting resolution for use is being advisable of 320 * 240pixel.
The characteristics of native system are that portable monitoring combines with fixed monitoring, long 120 meters at one, in the wide 60 meters transformer station, the thermal infrared imager of the thermal infrared imager of the thermal infrared imager of two 640 * 480pixel, two 160 * 120pixel and a 320 * 240pixel, be used by The Cloud Terrace and just can finish the accurately comprehensively monitoring to whole transformer station, greatly reduce hardware cost, front monitoring front-end has also alleviated staff's monitoring work less simultaneously, has improved operating efficiency; And utilizing the network switch to connect monitor terminal and data processing server, realization local area network terminal and wide area network terminal are monitored jointly. In bigger transformer station, only need to increase the number of panorama monitoring thermal infrared imager, need not to increase other hardware devices and just can finish monitoring.
