48Hr Non-Stop Operation! InfiRay® Thermal Imaging Monitoring Solution for High-Voltage Substations
Automatic control and unattended operation of electric devices have become a trend with the continuous development of technology. As the smart grid renovation is now in full swing, monitoring of data, environmental parameters, and images of key devices such as transmission and distribution power plants, substations, and transmission and distribution lines is required to keep track of device operation in real time and respond to emergencies on time. In the substation process, transformers, bushings, cable clamps, disconnectors and other key devices are frequently used with high-level reliability requirements. Once overheating occurs, it is liable to cause accidents and affect the safe operation of a substation. Hence, employing thermal imaging to measure temperature and perform diagnoses 24-7 is necessary to avoid undesired consequences.
I. Pain Points
There are various solutions on the market for measuring the temperature of key devices, mostly contact measurement. The implementation of such solutions involves a large number of wiring and device transformations, and requires considerable construction effort. In addition, once implemented, it is difficult to increase or move the temperature measurement points. The traditional measurement system only serves to provide very basic temperature information instead of more explicit images or videos, thus inconvenient for the analysis and solution of problems. Infrared thermal imaging is non-contact remote monitoring, dispensing with any transformation to original devices. The installation of it is simple and can be done for measuring the temperature of a specific point/line/area, together with alarm linkage, avoiding serious consequences caused by overheating as far as possible and minimizing possible losses.
II. Solution Application
FB2/FB4/PT2 series provide different focal lengths and the choice can be made according to the actual needs. FB2/FB4 camera can be connected with a POE switch for power supply and network access.
Draw the measurement area and set the measurement and alarm rules.
After configuration, use a backend IVS/NVR device or monitoring platform for unified management.
