Is it necessary to install fuses on the primary side of 110kV and above voltage transformers? Is the following statement correct? ()
A、110kV and above system is neutral point directly grounded system, each phase of the voltage transformer can withstand the line voltage operation for a long time, so there is no fuse installed in the primary side
B、110kV and above system is neutral point directly grounded system, each phase of voltage transformer cannot bear line voltage operation for a long time, so fuse is not installed in the primary side
C、 The structure of 110kV and above voltage transformers adopts single-phase cascade type, with high insulation strength, so no fuse is installed in the primary side
D、Fuses shall be installed on the primary side of 110kV and above voltage transformers
