Research on Non-electric Quantity Protection of Oil-Immersed Equipments of HVDC Project
The configuration of non-electrical protection of large oil immersed equipments is very important to ensure the reliable running of HVDC system.Introduced field configuration and operation experience of non-electric quantity protection,discussed the technological requirements of electrical equipments in terms of anti-disturbance and action logic configuration of non-electric quantity protection.To the fieldwork,explicited the demand of secondary circuit design,proposed the measures of improving the reliability of non-electric quantity protection.
