Abstract:

In order to make full use of the miniaturization, standardized interface and plugandplay of local protection device, an implementation scheme for local protection device grid connection and trial operation based on quasi twoterminal prefabrication is proposed. And focus is made on the installation scheme based on secondary system prefabricated box which realizes the local protection interval and prefabricated installation. Based on the structural and functional configuration of the prefabricated box for secondary system, the networking scheme of local protection is put forward, and the prefabricated interface and objectorientation loop connection scheme based on secondary system prefabricated box is emphasized.
