Most oil fields in China require stable power supply from 35kV substations for normal production.Currently,the failure of a single main transformer in a 35 kV substation is the main cause of power supply risk.Therefore,it is necessary to analyze the characteristics and faults of the main transformer in a 35 kV substation based on the practical needs of ensuring power production in China's oil fields.This is a crucial link in the technical support of oil field power.By analyzing the noise and temperature rise indicators of the main transformer in a 35kV substation,as well as the four common fault situations,it can provide direction for fault prevention and troubleshooting,and is also a key task for the maintenance of power equipment in actual substations.
