		    摘 要:環(huán)網(wǎng)柜受潮、浸水會發(fā)生電氣故障,導(dǎo)致設(shè)備損壞,并可威脅人身安全。應(yīng)用有效的密封結(jié)構(gòu)對保障環(huán)網(wǎng)柜正常運(yùn)行和提高配電網(wǎng)供電可靠性意義重大。針對環(huán)網(wǎng)柜的密封結(jié)構(gòu)展開分析,探討了橡膠密封圈的密封原理、設(shè)計(jì)原則以及螺栓緊固結(jié)構(gòu)設(shè)計(jì),并對環(huán)網(wǎng)柜密封結(jié)構(gòu)的優(yōu)化設(shè)計(jì)提出了改進(jìn)建議,為推動設(shè)備質(zhì)量提升,提升配網(wǎng)運(yùn)行可靠性提供了理論支持。

					    Abstract: Moisture and water immersion in ring main units (RMU) can cause electrical faults, equipment damage and posing a threat to personal safety. Thus, the application of effective sealing structures is of great significance for ensuring the normal operation of RMU and improving the reliability of power supply in distribution networks. This paper analyzes the sealing structure of the RMU, discusses the sealing principle of the rubber sealing ring, design principle, and the design of the bolt fastening structure, and puts forward improvement suggestions for the optimized design of the sealing structure of RMU, providing theoretical support for promoting the improvement of equipment quality and enhancing the reliability of distribution network operation.
				
					    Key words: rubber sealing ring; sealing; bolt fastening; ring main unit
