| Abstract: | At present, the widely applied mechanical on-load tap-changer is not suitable for the 10 kV power distribution network.Along with the development of power electronic technology, there has the report on on-load tap changing (OLTC) distributing transformer based on the power electronic technology. In this paper, the analysis on the characteristic of several kinds of non-contacts OLTC distributing transformer was carried on. The result indicates that OLTC distributing transformer based on the solid state relay has the broad applied prospect in the 10 kV medium distribution network. |
