Abstract

In consideration of the anti-short circuit ability of transformer impacted on the power system

the zero loss deep current limiting technology is put forward to improve the anti-short circuit ability of transformer in this paper.Firstly

the fault type and dynamic stability of transformer are analyzed from physical perspective

and the specific cause for the decline of anti-short circuit ability of transformer is studied.Further the basic working principle of the zero loss deep current limiting technology is analyzed

the obtained conclusion is that the technology can improve the anti-short circuit ability of transformer.Finally the basic application principle is put forward that the anti-short cir cuit ability of transformer promoted by the zero loss deep current limiting technology

and the feasibility of this method is analyzed by an example.The method proposed in this paper to improve the anti-short circuit ability of transformer is more economic and efficient.
