   岛主，我一直记得这件事情的，只是最近比较忙，这边有点顾不过了，在等两天等手上的事情告一段落，我会回来继续的。

学习随时都可以，等你有空了继续分享，我感谢先。

7 Operating conditions and interpretation of results

第7章：运行条件和结果说明

When measurements of disturbance are being made, the appliance shall be operated under the following conditions:

在进行骚扰测量时，器具应按如下条件运行。

第七章讲解的是在测试时，器具的运行状态。

各位其实可以再看标准的时候，首先大致浏览目录，这样知道每章重点讲解的内容，弄明白标准的逻辑安排，本人认为这是对标准比较正确的学习方法。

7.1 General  总则
7.1.1 Normal load conditions shall be as defined in 7.2 and 7.3, unless these are in conflict with the manufacturer's instruction for use, which in such cases take precedence. Where appliances are not covered by these subclauses, the manufacturer's instruction for use shall be followed.

正常的负载是由7.2和7.3确定，除非这些鱼制造商的说明书有矛盾，在此情况下，优先选取制造商说明书中规定的条件。对于不包括在这些条款中的器具，应参照制造商的使用说明书。

7.1.2 The duration of operation is not restricted unless the appliance is marked accordingly. In this case the limitations shall be complied with.

器具的运行时间不受限制，除非器具上标有相应的规定，在此情况下应符合此规定。

7.1.3 No running-in time to be specified but, prior to testing, the appliance shall be operated for a sufficient period to ensure that the conditions of operation will be typical of those during  normal life of the equipment. Running-in of motors shall be carried out by the manufacturer.

没有预运行时间的规定，但在测试之前，器具应运行足够长的时间以保证运行条件是器具正常寿命期间的典型条件。电动机的预运行应由制造商运行。

7.1.4 The appliances shall be operated from a supply that provides the rated voltage and the rated frequency of the appliance.

器具应连接到能为其提供额定电压和额定频率的电源上运行。

A test at about 160 kHz and at about 50 MHz shall be made over a range of 0,9 to 1,1 times the rated voltage in order to check whether the level of disturbance varies considerably with the supply voltage; in which case, the measurements are to be made at the voltage that causes maximum disturbance.


应在0.9-1.1倍的额定电压范围内，在160kHz和50MHz两个频点上进行测试，以检查骚扰电平是否随着电源电压变化而有明显的变化；在此情况下，应在引起最大骚扰的电压下进行测量。

If an appliance has a rated voltage range, the multipliers 0,9 and 1,1 apply to the lowest and highest, most common nominal supply voltages that fall within the rated voltage range that is specified by the manufacturer.

如果器具有一个额定电压电压范围，则对应的最低电压，最高电压及在制造商规定的电压范围内的常用的标称电压乘以0.9和1.1的系数。

NOTE The most common nominal supply voltages are 100 V, 110 V, 115 V, 120 V, 127 V, 220 V, 230 V, 240 V and 250 V.

注：最常用的标称电压为100 V, 110 V, 115 V, 120 V, 127 V, 220 V, 230 V, 240 V 和 250 V.
