井下低压开关选择与整定对供电可靠性影响

Underground low-voltage switch selection and setting effects on supply reliability

井下低压开关选择与整定,直接影响低压电网故障时保护装置动作选择性、供电可靠性。保护装置拒动、误动将使故障扩大、大面积停电。分析井下低压开关选择与整定对供电可靠性影响,对提高供电可靠性具有十分重要的意义。

The selection of underground low voltage switch and setting affect the selectivity of protective devices,power supply reliability when the low voltage networks fault.Refuse and malfunction of protection equipment will expand the blackouts.Analysis of underground low voltage switches selection and setting effects on supply reliability,and it will improve the reliability of great significance.
