Details
I. Substation infrared intelligent online real-time monitoring system
Infrared intelligent online real-time monitoring system is a real-time monitoring and detection system integrating visible light, infrared thermal imaging and embedded processing technology. The system can carry out automatic inspection, real-time monitoring, automatic alarm, real-time acquisition of equipment fault state thermal information, and automatically generate the corresponding temperature change report. It has the characteristics of no power failure, remote, safe and reliable, high detection accuracy. It is a very effective method to realize online monitoring and equipment condition maintenance.
System characteristics
1, the system has preset travel, efficient use of intelligent mode of operation, without care for system self-check
2. When the temperature of the target equipment is abnormal, it will automatically warn the personnel of the specific location information and provide the efficiency of troubleshooting
3. Remote power infrared video monitoring for substation scene
4, transformer, circuit breaker and other important operating equipment in the substation appearance state, working state, temperature field distribution monitoring
5. Monitor the appearance, working status and temperature field distribution of CT, PT, arrester, porcelain insulator and other high voltage equipment in the substation
6. Monitor the appearance, working status and temperature field distribution of other oil-filled equipment and flammable equipment in the substation
7. The infrared video monitoring inside and outside the substation has alarm hard contacts connected to the substation integrated automation system or remote equipment to provide fire protection and early warning motion alarm information
The infrared thermal imager in the system collects infrared heat map and measures the surface temperature of the monitoring device in real time. The infrared heat map and temperature data are transmitted to the monitoring host through PAL interface and RJ45 interface, and the operation of the monitoring device can be observed in real time on the monitoring host. Meanwhile, the monitoring host can compress the image and temperature data and send them to the LAN through the network device. Realize real-time network monitoring. At the same time, due to the different installation methods, the equipment can be divided into fixed online monitoring, airborne online monitoring, vehicle online monitoring, mobile online monitoring and so on.
System advantage
1. The precise position and working temperature of the equipment in the figure can be obtained through intelligent infrared panoramic splicing technology
2. The international leading intelligent identification system for substation equipment
3, the front end of the instrument temperature measurement technology
It can work independently, and the front-end thermal imager can complete all the temperature measurement work, and transmit the infrared image and the original temperature measurement data to the information center or the field workstation. There is no signal compression, no signal loss, strong anti-interference, to ensure the accuracy and stability of temperature measurement data.
4, full real-time image, image without delay phenomenon
The frame rate of the image is 25 frames per second, and the image is completely real-time, with no image pauses, image lags, or jumping sensation. It avoids the difficulty of adjustment and observation caused by prominent lag in the process of the operator's rotation control of the head and focal length adjustment of the lens.
5, temperature measurement fast, accurate, good uniformity
In the process of changing with the scene, the system can always get all the observed temperatures instantaneously. The image has high uniformity, and there will be no difference in temperature measurement due to the change of the scene.
6. Infrared image compression and network transmission
Ethernet connection mode, each has a separate URL, can be addressed independently through the Ethernet, can form a monitoring network, not only can be used with the whole control system, can also be used separately, generate high ratio thermal image, each pixel in the image for separate temperature measurement, support 25 frames/second thermal image output analysis.
7. Automatic cruise
The system has the automatic inspection function, which can monitor the working state of all the equipment in the predetermined time according to the pre-specified inspection trip, and make maximum use of the intelligent way of the computer system, without taking care of automatic inspection. In the process of inspection, once the temperature of the target device is abnormal and exceeds the preset alarm temperature, the system will automatically alarm, store the heat map of the working state of the device, and remind the operator of the specific location information of the faulty device, so that the operator can immediately troubleshoot the fault and give the work report
8. IP67 protection level
The system can work normally in harsh climate environment, with super low temperature environment protection, as well as high temperature, high humidity resistance performance. No matter it is windy and rainy, hot and humid, or cold and cold, it can realize uninterrupted automatic monitoring to ensure the normal operation of power transmission and transformation equipment in the cold regions in the north and the hot and hot regions in the south.
