| Abstract: | The voltage-rise reforming of domestic switchgear from 10 kV to 20 kV is comprehensively analyzed and a reliable and economical solution of voltage-raise reforming is provided for the withdrawable switchgear,fixed switchgear and ring-net switchgear,which adopts the optimization of internal structure.Study shows that most of domestic 10 kV switchgears can be upgraded to 20 kV voltage level by means of internal structure optimization on the premise that the safety and reliability of cabinet are assured. |
| Keywords: | 10 kV distribution network 20 kV electric switchgear reforming optimization |
