7.2.6 Regulating controls incorporating semiconductor devices

装有半导体调节装置的调节控制器

7.2.6.1 Adjustments for maximum disturbance level
The regulating control shall be adjusted to give a maximum indication on the meter at each frequency of measurement. After the value of the disturbance is registered at each preferred frequency (see 7.4.1.3) the frequency band adjacent to the preferred frequency is scanned without adjustment to the regulating control and the highest disturbance values are noted (for instance scan between 150 kHz and 240 kHz with the regulating control set at the value that gave the maximum on the meter at 160 kHz).

调节控制器应调节到使接收机在每一个测量频率上给出最大指示值的位置。记录每个优先频率点（见7.4.1.3）的骚扰值后，不改变调节控制器，在优先频率点附近的频带内进行扫描，并记录最大骚扰值（例如，调节控制器设定在160kHz上接收机给出最大值的位置，再进行150kHz-240kHz范围内进行扫描）。

7.2.6.2 Equipment with several regulating controls
The following measurement procedure shall be applied to appliances containing several individually adjustable regulating controls each one having a maximum rated load current of not more than 25 A.

有若干个调节控制器的设备

下述测量程序适用于若干个分别可调的控制调节器并且每个控制调节器最大额定负载电流不大于25A的器具。

It shall be applied both on appliances where several regulating controls are connected to the same phase of the mains and to appliances where the regulating controls are connected to separate phases of the mains.

本条款对几个调节控制器接到电源的同一相和调节控制器分别接到电源的不同相的两种器具都适用。

7.2.6.2.1 Each regulating control is tested separately. Measurements are made in accordance with 7.2.6.1 on all terminals of the appliance.
If separate switches are provided for the individual regulating controls, the units not being used should be switched off during these tests.


每个调节控制器应分别测试。按7.2.6.1在器具的所有端子进行测量。

如果单个调节控制器装有单独的开关，在试验期间不用的调节控制器应断开。

7.2.6.2.2 As many individual regulating controls as possible are connected to their loads without the maximum current per phase to the appliance exceeding 25 A when each of the controls is carrying its maximum rated current.

每个控制器带上其最大的额定电流负载，在器具的每相最大电流不超过25A的前提下，将尽可能多的调节控制器连接到负载上。

When not all individual controls can be connected to their maximum load, those controls are given priority which gave the highest disturbance values when tested in accordance with 7.2.6.2.1.

在不可能所有单个控制器都接到最大负载时，那些按7.2.6.2.1测试时产生最大骚扰电平的控制器应具有优先权。

NOTE The controls may be different for different frequencies or for different terminals.

注：对于不同频率或不同端子，控制器可能不同。

The setting of the individual controls shall be the same as those giving maximum disturbance during the measurement in accordance with 7.2.6.2.1. In addition a simple check shall be made that no other setting will give greater disturbance.  Measurements are made on the mains terminals, all phases and neutral, on the terminals to the loads and on additional
terminals of the appliance.

单个调节控制器的设定应与在7.2.6.2.1测量期间给出的最大骚扰的那些设定相同。应增加一个简单的核查以确定没有其他设定会产生更大的骚扰。测量应在器具的电源端子，包括所有的相线和中线，负载端子和附加端子上进行。

This test is not made when each individual regulating control consists of an entirely selfcontained regulating circuit including all suppression components and operates independently  of the others and does not control, either by design or fortuitously, any load that another individual regulator is controlling.

当每个单独的调节控制器是由自带的完整调节电路，包括抑制元件，独立于其他控制器工作，且由于设计或其他原因使其不能控制其他调节控制器正在控制的任何负载时，则不进行本试验。

7.3 Standard operating conditions and normal loads

标准运行条件和正常负载

由于下面的产品都是比较常见的产品，在认证中也是出现的最多的产品，因此我打算重新发帖专门讲解下面的电动、电热类产品。

针对第七章的内容，主要讲解的测试状态和负载，因此大家需要注意的一点是，针对每个条款，描述的对象产品是什么，这个是理解每个条款的基本要求，否则会出现不知所云的感觉。
