On-Line Monitor Device Of Gas In Oil Of Transformer

As one of the most important electric power equipments in electric power system, the transformers have determinative importance for improving the reliability of power supply and the safety directly. During the period of runs or faults, transformers must produce some combustible gases. So, these gaseous compositions and contents can acts as a index, and the Departments have established the related standard.Generally speaking, the traditional monitoring method is take out oil-samples or iron-core from transformers, as a result, it lead to the cost high, the reliability of power supply poor. The worst of all, the method can't forecast the state of transformers in time. In this thesis, the on—line monitor device is discussed. Considering the related Department standard and the experience of transformer substation, the device, in which the combustible gases are indexes, comprise sensor (TGS813), MPU (TMS320LF2407A), display unit (LED) and communication unit (RS232 and CAN2.0). Before this thesis, the device has been finished and debugged successfully.
