The application discloses a partial overheating positioning method for a converter
transformer, which comprises the following steps: firstly,
temperature monitoring is performed on an
oil tank temperature probe, a sleeve temperature probe, an upper clamp temperature probe, a lower clamp temperature probe, a pull plate temperature probe, a
core temperature probe and a winding temperature probe, and real-time gas production monitoring is performed on a gas production regularity monitoring device; secondly, whether partial overheating occurs is determined based on a threshold value determined by a BP neural network
algorithm; according to the determination result, whether the temperature of a clamp, a pull plate, a core, a winding, an
oil tank and a sleeve structure is locally overheated is determined in sequence; finally, a result of a local overheating position is outputted and a prompt is given. The method can display the temperature of each structure in real time and determine whether a local overheating fault occurs. For the problem of local overheating of the converter
transformer, a heating point can be quickly found, so that the converter
transformer can be protected to operate at a safe
working temperature.
