外壳防护等级国际标准
外壳防护等级是指电气设备对外部环境的防护能力,通常采用国际标准IEC 60529(GB/T 4208-2017)进行分类和命名。
该标准将外壳防护等级分为七个等级,分别为:
1.等级0:无防护(No protection);
2.等级1:防止直径大于50mm的物体进入(Dust protected);
3.等级2:防止直径大于12mm的物体进入(Protected against harmful ingress of water);
4.等级3:防止水滴进入,垂直滴水(Spray protected);
5.等级4:防止飞溅水进入(Splash protected);
6.等级5:防止低压喷水进入(Water jets protected);
7.等级6:防止高压喷水进入(Immersed in water)。
每个等级都有相应的测试要求和标准,以确保设备具有足够的防护能力。
在实际应用中,需要根据使用环境和设备的特点选择适合的防护等级。

干变外壳防护等级标准干变外壳防护等级是针对电力设备中的干式变压器而设立的一项标准,旨在提供变压器外壳的防护等级,以保护变压器免受灰尘、水分、物理冲击和其他恶劣环境因素的影响。
根据国际电工委员会(IEC)和国家标准,干变外壳防护等级可依据不同的防护需求分类,并通过相应的防护等级代码进行表示。
下面是一些相关参考内容,用于了解干变外壳防护等级标准的概念和应用。
一、国际电工委员会(IEC)标准1. IEC 60529 标准IEC 60529 标准是国际电工委员会制订的防护等级(IP标准)的国际标准。
该标准规定了不同等级的防护构造要求,包括防护等级代码的定义及测试方法等。
在干变外壳防护等级标准中也常使用该标准进行参考。
2. IEC 61892-7 标准IEC 61892-7 标准是国际电工委员会制订的用于海洋上的电气、电子和可编程电子设备的安装设计的标准,该标准也包含了干变外壳防护等级标准的相关内容。
二、干变外壳防护等级标准分类根据不同的防护需求,干变外壳防护等级可分为以下几个分类:1. IP10X该等级表示变压器具备防护物体直径大于50mm的保护能力。
这意味着变压器的外壳能有效地防止大于50mm直径的物体侵入变压器内部。
2. IP20该等级表示变压器具备防护物体直径大于12.5mm的保护能力。
相比于IP10X,该等级提供更高的防护能力,能够有效地防止直径大于12.5mm的物体进入。
3. IP30该等级表示变压器具备防护物体直径大于 2.5mm的保护能力。
相比于IP20,该等级提供了更高的防护能力,能够有效地防止直径大于2.5mm的物体进入。
4. IP40该等级表示变压器具备防护物体直径大于1mm的保护能力。
相比于IP30,该等级提供了更高的防护能力,能够有效地防止直径大于1mm的物体进入。
5. IP50该等级表示变压器具备防护物体直径大于0.5mm的保护能力。
相比于IP40,该等级提供了更高的防护能力,能够有效地防止直径大于0.5mm的物体进入。
外壳防护等级外壳防护等级(IP代码)是将产品依其防尘、防止外物侵入、防水、防湿气之特性加以分级。
这里所指的外物包含工具、人的手指等均不可接触到灯具内之带电部分,以免触电。
它一般是由两个数字所组成,第一个数字表示产品防尘、防止外物侵入的等级;第二个数字表示产品防湿气、防水侵入的密闭程度。
数字越大,表示其防护等级越高。

Developed by the European Committee for Electrotechnical Standardization (CENELEC), these standards are designed to numerically rate an electrical product on the level of protection its enclosure provides. By assigning different number codes, the product's degree of protection can be identified quickly and easily. In the code IP 54, for example, IP identifies this standard, the 5 describes the level of protection from solid objects, and 4 describes the level of protection from liquids.Second Characteristic Numeral DEGREE OF PROTECTION (Second Number in Code)Brief DescriptionDefinition0 Not protected __1 Protected against vertically falling water drops.Vertically falling drops shall have no harmful effects.2Protected against vertically falling water drops when enclosure is titled up to 15 °.Vertically falling drops have no harmful effects when the enclosure is tilted at any angle up to 15° on either side of the vertical. 3 Protected against spraying water. Water sprayed at an angle up to 60° degrees on either side of the vertical shall have no harmful effects. 4 Protected against splashing water.Water splashed against the enclosure from any direction shall have no harmful effects. 5 Protected against water jets. Water projected in jets against the enclosure from any directionshall have no harmful effects.6 Protected against powerful water jets.Water projected in powerful jets against the enclosure from any direction shall have no harmful effects.7Protected against the effects of temporary immersion in water.Ingress of water in quantities causing harmful effects shall not be possible when the enclosure is temporarily immersed 1 meter in water under standardized conditions of pressure and time.8Protected against the effects of continuous immersion in water.Ingress of water in quantities causing harmful effects shall not be possible when the enclosure is continuously immersed in water under conditions which shall be agreed between manufacturer and the user, but are more severe than for number 7.International Protection (IP) RatingsThe IP rating system classifies the degree of protection from solid objects and liquids afforded by electrical equipment and enclosures.
