Abstract
Aiming at the problem of protection blind area existing in configuration schemes of current transformer of 330 kV substation in general design,by analyzing the characteristics of current transformer,puts forward improvement measures such as to increase number of current transformer winding,adopt TPY level current transformer for the main transformer protection in one and a half circuit breaker connection (3/2 connection) mode, etc. The result shows that the improvement measures can effectively prevent the accident scope spreading,guarantee the power grid safe and reliable operation,reduce economic loss of power grid enterprises and customers.关键词
