Background technology
When dry-type power transformer runs, transformator is in the case where load and radiating condition, ambient temperature are all constant, temperature
Degree is constantly raised, and first should be ascertained the reason, then is taken appropriate measures and excluded.If what power transformer interior fault caused,
Should be out of service, overhauled.Temperature anomaly is caused to have the reason for rising：1st, Transformer Winding local interlayer or turn-to-turn is short
Road, interior contacts are faulty, and contact resistance is increased, and has big resistive short etc. on secondary line；2nd, transformer core local is short
Road, the punching screw insulation damages for clamping iron core；3rd, long-term running overload or accident overload；4th, radiating condition deteriorates
Deng；And function of the existing transformator generally without high temperature early warning, this service life for being just easily caused transformator reduces, fault rate liter
High.
