变压器需要哪些保护要看变压器的电压等级，容量，工作环境等因素。
这个给一个1一个例子
10MVA, 50HZ, 11/132 kV step-up transformer，outdoor, oil immersed, nature air cooled (ONAN), Dyn11 (HV neutral earthing is of solidly earthed), with on-load manual tap changer ±4x2.5% on HV winding.
The transformers are fitted with the following accessories:
1) Breather
2) Oil conservator with level gauge and sight glass
3) Oil dram plug
4) Valve for oil samples
5) RTD for oil and winding (Pt=100)
6) Dual contact type oil and winding thermometers
7) Buchholz relay
8) A ladder for access to the Buchholz relay
9) Flanged wheels
监控保护内容有：
26 TEMPERATURE INDICATOR
27 UNDER VOLTAGE RELAY
49T TRANSFORMER TEMPERATURE PROTECTION
63 BUCHOLZ RELAY
64T NEUTRAL POINT EARTH FAULT RELAY
71T TRANSFORMER OIL LEVEL
151 OVERCURRENT RELAY
164 LINE ERATH FAULT RELAY
PR PRESSURE RELIEF DEVICE
