EN 60335-1 三相电器 相关条款总结:
1. Scope:
This European Standard deals with the safety of electrical appliances for household environment and commercial purposes, their rated voltage being not more than 250 V for single-phase and 480 V for others:
2. 7.1： The marking of rated voltage or rated voltage range, for appliances intended to be
connected to the
- 230 V for single-phase appliances;
- 400 V for multi-phase appliances. 多相器具工作电压需要包含400V 3. 7.3:
NOTE 3 This requirement is also applicable to appliances with provision for connection to both single-phase and multi-phase supplies.
器具标称额定值的标称方式： 范围用“-”,需要调节的用“/”，这种标称方式同样适应多相器具
Example: 230 V/400 V: The appliance is only suitable for the voltage values indicated, 230 V being for single-phase operation and 400 V for three-phase operation (a dishwasher with terminals for both supplies).
4. 7.6： 5. 7.7：Appliances to be connected to more than two supply conductors and appliances
for multiple supply shall have a connection diagram fixed to them, unless the correct mode of connection is obvious.
连接到2根以上的供电导线的器具或者多源器具， 除非正确的连接方式是很明确的，否则器具因有一个连接图，并固定到器具上。
Compliance is checked by inspection.
NOTE 1 The correct mode of connection for multi-phase appliances is considered to be obvious if the terminals for the supply conductors are indicated by arrows pointing towards the terminals. 三相器具，如果连接导线的连接线用箭头指向接线端子，则认为其正确的连线方式是很明确的。
6. Three-phase appliances, which according to the instructions for installation are also
suitable for single-phase supply, are tested as single-phase appliances with the three circuits connected in parallel. 三相电器，根据安装说明也适用于单相供电。按照3个单相电路星型并连测试。
7. For three-phase appliances, the measuring circuit is shown in the following figures: - if of class II, Figure 3; 三相器具，class II 结构按照图3
-if other than class II, Figure 4. 三相器具，除class II 结构按照图4
For three-phase appliances, the leakage current is measured with the switches a, b and c in the closed position. The measurements are then repeated with each of the switches a, b and c open in turn, the other two switches remaining closed. For appliances intended to be connected in star connection only, the neutral is not connected. 对于三相器具的泄露电流，按
照图3或者图4，将图中a,b,c位置闭合后测得。然后轮流将3个开个一次断开一个，另外2个闭合再测试一次，器具用星星连接，中线不需要连接。
8. 13.3 table 4:
a For multi-phase appliances, the line to neutral or line to earth voltage is used for rated voltage. The test voltage for 480 V multi-phase appliances is that specified for a rated voltage in the range 150 V and 250 V. 对于多相器具，额定电压是指相线与中线或者接地之间的电压。对于480V的多相器具， 测试电压按照额定电压150V-250V的范围进行。 9. 16.2 冷态下的泄露电流：
-1,06 times rated voltage, divided by 3 , for three-phase appliances： 测试电压为1.06U/?3
10. 19.8 One phase of appliances incorporating multi-phase motors is disconnected. The
appliance is then operated under normal operation and supplied at rated voltage for the period specified in 19.7.
装有三相电机的器具，断开其中的一相，对器具施加额定电压，在正常工作状态下，工作持续到19.7规定的时间。
理解要点：三相电机在断开一相的情况下，电动机的工作特性将恶化。本条款检查带三相电动机在缺相情况下的安全性能。
11. 25.5：For multi-phase appliances that are supplied with a supply cord and that are
intended to be permanently connected to the fixed wiring, the supply cord shall be
assembled to the appliance by a type Y attachment. 带电源线并用于连接到永久固定布线的多相器具，电源线的装配方式应为Type Y.
12. 25.8 table: NOTE For supply cords supplied with multi-phase appliances, the nominal
cross-sectional area of the conductors is based on the maximum cross-sectional area of the conductors per phase at the supply cord connection to the appliance terminals.
对于多相器具的电源线导体的截面积基于单相电源线里最大的电流所确认的截面积。
13. 29.1 Table 15 电气间隙的额定电压：NOTE 1 For multi-phase appliances, the line to
neutral or line to earth voltage is used for rated voltage.
14. 29.2 爬电距离：NOTE 1 The working voltage for parts connected to the neutral is the
same as for parts connected to the phase and this is the working voltage for basic insulation. 对基本绝缘连接到中性线的工作电压值与连接到相线的工作电压值一样 15. 29.2.4 table 18 功能性绝缘爬电距离:
b The working voltage between phases for appliances having a rated voltage in the range of 380 V to 415 V is considered to be 400 V. 在相线间的工作电压范围380-415V按照400V考虑。
