Abstract
For the power main transformer is prone to near-area continuous short circuit fault,110 kV main transformer short circuit fault as an example,carried out on-site inspections and tests,analyzed the transformer short circuit fault reasons,and put forward some specific prevention and control measures for the reasons,after analysis of the main transformer short-circuit resistance is insufficient to trigger the low-voltage windings in the near-area short-circuit current under the continuous action of the electrodynamic force of deformation,so that the transformer turn-to-turn insulation breakdown short circuit.Transformer turn-to-turn insulation breakdown short-circuit,which should strengthen the operation and maintenance management of the old transformer,optimize the protection value setting,in order to reduce the short-circuit failure rate of the transformer,to better protect the safe and continuous and stable supply of electric energy.关键词
