Abstract: The existing transformer fire - extinguishing methods have different advantages and disadvantages,and there are many kinds of transformers with irregular shape, what kind of fire extinguishing system they are suitable for needs to be known through a large number of true type tests. In this paper, the building method of real type test platform that covers several kinds of fire - extinguishing methods is put forward, which can provide reference for the real type transformer coupling fire - extinguishing test; The fire  - extinguishing test of 10kV real transformer was carried out,which showed that the fire - extinguishing effect of adding oil emulsified fire - extinguishing agent on water mist and mobile fire - extinguishing platform is improved by more than two times, and the auxiliary effect of mobile fire - extinguishing platform on water mist fire - extinguishing system is significant.

Key words: transformer, fire, true type test platform, coupling fire-extinguishing test, oil emulsified fire - extinguishing agent
