| Abstract: | Based on the analyses of several special problems with 3/2 circuit breaker connection and the site experience for more than ten years in the south part of Hebei power system, this paper proposed a disposition scheme of pro- tection for 3/2 circuit breaker connection. Several problems of the protection for 3/2 circuit breaker connection are discussed in detail, and the corresponding measures for salving these problems are also proposed. Finally, this paper rec- ommends the principles for choosing different protections for the 3/2 circuit breaker connection, when reconstruction the old sub-stations or constructing the new sub-stations or power plants. |
