What are the Insulation Accidents Often Likely to Occur in Transformer Insulation Materials?

1.Winding insulation accident. 
Refers to the insulation accidents caused by the discharge and burning loss of main insulation, turn insulation, section insulation, lead insulation and end insulation.
2.Casing insulation accident. 
Refers to the insulation damage caused by the discharge of insulation inside the casing, or even the explosion of porcelain sleeve.
3.Insulation accident of tap switch. 
It mainly refers to the serious decline in the insulation strength of the switching switch oil room, which can not be extinguished when switching tap, causing the load tap switch to burn. There is no excitation tap switch and on load tap switch exposed conductor discharge, cause phase, ground or stage short circuit accident.
4.Core insulation accident. 
One is that the silicon steel sheet of the iron core is damaged to the ground insulation, causing the multi-point grounding of the iron core. The other refers to the insulation damage between the frame connection point of the iron core, resulting in local overheating caused by circulation.
