NEMA 防护等级 分类 _ 工业工程网

</script>NEMA 防护等级 分类
NEMA是由美国制造商们组织起来的，是制定电气设备标准化产品技术规格的一个组织机构。
NEMA所制定的标准和测试方法被应用到了UL（担保人试验室）测定、认定电气密封箱的基本方针。
括号里面是指相应的IP等级

NEMA1:                Indoor use primarily to provide a degree of protection against contact with the enclosed equipment and against a limited amount of falling dirt. (IP30)
2:      Indoor use to provide a degree of protection against limited amounts of falling water and dirt. (IP31)
3:      Outdoor use to provide a degree of protection against windblown dust, rain, and sleet; undamaged by the formation of ice on the enclosure. (IP64)
3R:      Outdoor use to provide a degree of protection against falling rain and sleet: undamaged by the formation of ice o the enclosure. (IP32)
3S:      Outdoor use to provide a degree of protection against windblown dust, rain and sleet; external mechanisms remain operable while ice laden.
4:      Indoor or outdoor use to provide a degree of protection against splashing water, windblown dust and rain, hose directed water; undamaged by the formation of ice on the enclosure. (IP66)
4X:      Indoor or outdoor use to provide a degree of protection against splashing water, windblown dust and rain, hose directed water; undamaged by the formation of ice on the enclosure, resists corrosion. (IP66)
6:      Indoor or outdoor use to provide a degree of protection against the entry of water during temporary submersion at a limited depth; undamaged by the formation of ice on the enclosure.
6P:                Indoor and outdoor use to provide a degree of protection against the entry of water during prolonged submersi at a limited depth.
11:      Indoor use to provide by oil immersion a degree of protection of the enclosed equipment against the corrosive effects of corrosive liquids and gases.
12,12K:      Indoor use to provide a degree of protection against dust, falling dirt and dripping noncorrosive liquids. (IP65)
13:      Indoor use to provide a degree of protection against dust and spraying of water, oil and noncorrosive coolants.

一看到楼主的气势，我就觉得楼主同在社区里灌水的那帮小混蛋有着本质的差别，那忧郁的语调，那熟悉的签名，还有字里行间高屋建瓴的辞藻。
