Background
The distribution transformer is called 'distribution transformer' for short, and is a static electric appliance which transforms alternating current voltage and current according to the electromagnetic induction law in an electric distribution system and transmits alternating current energy. In some areas, power transformers with a voltage class of 35 KV or less (mostly 10KV or less) are called "distribution transformers", and are referred to as "distribution transformers" for short. In the prior art, the temperature of the transformer cannot rise to the ignition point when the transformer works normally. Only in the event of a fault, the possibility of rising to the fire point is present. Such failures are generally due to increased current caused by increased resistance. There are generally two reasons for the increase in current: one is severe overload (including external short circuits); secondly, the transformer is damaged in an insulation way, internal short circuit occurs, and if the internal short circuit is severe, the transformer can explode. The reason for the increase in the resistance is contact failure, and a high temperature is generated in the place of the contact failure, causing a fire
