Aiming at the failure of dry-type transformers, a remote monitoring terminal based on cloud services was developed. The terminal collects and displays parameters such as temperature and electrical parameters in real time through the data acquisition module, and automatically controls the start and stop of the fan according to the temperature. Sound and light alarm, protection tripping, GPRS wireless communication and GPS global positioning module positioning transformer, and send the sampled data to the specified mobile phone number for status monitoring; In addition the terminal can achieve remote data reception and storage through the cloud server , Send and other functions, and through the cloud server to the upper computer to transfer position and sampling parameter information, to facilitate the implementation of remote monitoring of each transformer at the same time.
