Key Technologies Investigation of Damp-proofing and Anti-dewing for 12 kV High-voltage Switchgear
摘要
Abstract
Aimed at phenomena of damp and dew occur in 10 kV high-voltage switchgear, which will lead to serious failures to its internal electric equipment, this paper discusses the key technologies and designs the research scheme. First, starting from mechanism of occurrence of damping and dewing in switchgear, three major categories of damp-proofing and anti-dewing technologies applied currently are summarized, including the heating dehumidification technology, condensing dehumidification technology, and dry-air dehumidification technology. Moreover, their merits and demerits are briefly analyzed. Then, based on the principle of dry-air dehumidification, which has the best performance among the three major approaches, the technique of anti-damping and anti-dewing for switchgear is investigated thoroughly, including dry-air source technology research and the corresponding device scheme design, as well as research on the technology of compulsory flow of the air in switchgear. Next, the scheme of the dry-air dehumidification based switchgear monitoring and control system is design. Finally, preventive measures for damp and dew occurred in switchgear are presented. In addition, its future development is prospected, and it is deemed that the dry-air dehumidification technology has a wide research space. This paper can provide some reference value and guide significance for the prevention and control of damp and dew phenomena in the 10 kV high-voltage switchgears in distribution networks.关键词
