High voltage cabinet is very important electrical equipment in the power system , and its many internal connector and contact head prone to local overheating , if not timely diagnosis and troubleshooting , high voltage cabinet insulation would suffer serious damage , and will eventually affect the stability and security of the power system . So it is necessary to monitor the high voltage cabinet contact temperature , enabling timely and effective discovery of potential accidents , in order to be processed . The thesis focuses on the above background, combined with advanced technology to design a set online monitoring system based on infrared temperature sensor and wireless data transmission module . First , on the basis of the existing power thermometry using infrared temperature sensors to measure the temperature of the sensor with a long-range , no contact , real-time , fast , etc. , can be well adapted to the temperature of the high-voltage electrical equipment online monitoring system , and a wireless module for data transmission , its no wiring , low cost, also bring convenience to the system . Followed by a brief description of the overall design of the system and each part is given , choose the appropriate device based on the system 's hardware design . Then communication protocols and software part of the system design and then write monitoring platform based on Visual Basic6.0 , given the on-site installation and commissioning of the sensor . Finally, the experimental simulation of the system passed the tests show that the system has the desired effect , and can find the security risks , and to ensure the safety and reliability of the high voltage cabinet .
