Problems solved by technology
If no measures are taken, it will cause serious consequences and even burn the transformer
In reality, there have been examples of severe faults in which the temperature of the transformer was too high, causing the transformer to spray oil and catch fire, causing the 10 kV line to trip.
When the transformer is in operation, the supervision and inspection of the maintenance personnel is often not in place, which is an important reason for the failure

Description
technical field [0001] The invention relates to the distribution transformer field, in particular to a distribution transformer over-temperature automatic communication alarm device. Background technique [0002] The distribution transformer is the main equipment in the power grid. When the transformer is running, a part of the electromagnetic energy is converted into heat and dissipated into the surrounding medium. Due to the overheating of the transformer, the aging of the transformer insulation will be accelerated. The higher the temperature, the longer the duration. The longer the winding is, the faster the aging of the winding will be. If no measures are taken, it will cause serious consequences and even burn down the transformer. In reality, there have been cases where the temperature of the transformer was too high, causing the transformer to spray oil and catch fire, causing serious faults such as tripping of the 10 kV line. When the transformer is in operation, th...
