新型户外用SF_(6)压力表计的研制

Development of a New Type of Outdoor SF_(6) Pressure Gauge

设计并制作一种新型户外用SF_(6)压力表计,以达到良好的防雨防潮效果以及满足多种安装方向的需要,无需另加防雨罩。提出“波纹管阻断”安装方法,以解决波纹管内部潮气因“烟囱效应”进入表计的可能,实现SF_(6)压力表计接点三重密封,具有垂直、左侧、右侧以及后侧等四种安装方向的特点。

A new type of outdoor SF_(6) pressure gauge is designed and manufactured so as to achieve good rainproof and moisture-proof effects and meet the needs of various installation directions without additional rainproof covers.The installation method of"waved pipe blocking"is proposed to solve the possibility of moisture inside the waved pipes entering the gauges due to the"chimney effects",which realizes the triple sealing of the contacts of SF_(6) pressure gauges,with the features of being installed in vertical,left,right and rear installation directions.
