Discussion on the Reliable Nuclear Phase Mode of the High-voltage GIS Power Distribution System

Jia Dong-hui

[Abstract]With the continuous development and progress of society， enterprises have higher and higher requirements for automation， intelligence， industrialization and large-scale， and the power demand and voltage level of related power distribution equipment are also higher and higher， in order to make better use of space， ensure safety and save maintenance cost， Gis gas-insulated metal-enclosed switchgear is often used in power distribution systems of 35 kV and above， it is very important to adjust the phase sequence and phase accurately. In this paper， the problem of phase check for 35 kV and above equipments is analyzed and sorted out， so as to improve the accuracy of line phase check.
