6 Methods of measurement of disturbance power (30 MHz to 300 MHz)
骚扰功率的测量(30M-300M)。
第六章讲的是另外一个测试项目骚扰功率(DP)的测量布置。
作者: stone0371 时间: 2012-6-20 20:47
This clause lays down the general requirements for the measurement of disturbance power produced at the terminals of apparatus.
本章列出了由器具端子产生的骚扰功率测量的一般要求。
The operating conditions are given in Clause 7 of this standard.
运行条件在本部分第7章中给出。
It is generally considered that for frequencies above 30 MHz the disturbing energy is propagated by radiation to the disturbed apparatus.
一般认为,频率超过30MHz以上时,骚扰能量是通过辐射传播到被骚扰的器具的。
作者: stone0371 时间: 2012-6-20 20:57
Experience has shown that the disturbing energy is mostly radiated by the part of the mains leads and other leads near the appliance. It is therefore agreed to define the disturbing capability of an appliance as the power it could supply to its leads. This power is nearly equal to that supplied by the appliance to a suitable absorbing device placed around these leads at the position where the absorbed power is at its maximum.
经验表明:骚扰能量主要是通过靠近器具的那部分电源引线和其他引线辐射的。因此同意用器具所能馈给电源引线的功率来确定其骚扰能力。该功率几乎等于器具馈给环绕这些引线的一个合适的吸收装置在吸收功率为最大值位置时的功率。
这句话应该这样理解,骚扰功率其实是辐射的一种测试项目,骚扰功率测试时是用过一个功率吸收钳在引线的每个位置所被馈给的最大功率值来确定的。
Calibration is accomplished in accordance with Annex B of CISPR 16-1-2.
校准按照CISPR16-1-2中附录B实施。

6.1 Measuring devices:测量设备。
6.1.1 Measuring receivers:测量接收机
Receivers with quasi-peak detectors shall be in accordance with Clause 4 of CISPR 16-1-1; receivers with average detectors shall be in accordance with Clause 6 of CISPR 16-1-1.
NOTE Both detectors may be incorporated in a single receiver and measurements carried out either using the quasi-peak detector or the average detecto。

6.1.2 Absorbing clamp:功率吸收钳
The absorbing clamp shall be in accordance with Clause 4 of CISPR 16-1-3.
吸收钳应符合CISPR16-1-3中第四章的规定。

6.2 Measurement procedure on the mains lead
电源线上的测量程序。
作者: stone0371 时间: 2012-6-22 16:56
6.2.1 The distance between the clamp test set-up (the appliance, the lead to be measured and the absorbing clamp) and any other conductive objects (including persons, walls and ceiling, but excluding the floor) shall be at least 0,8 m. The appliance to be tested shall be placed on a non-metallic support table parallel to the floor. The height of the table shall be 0,1 m ± 0,025 m for appliances primarily intended to be positioned on the floor in normal use, and 0,8 m ± 0,05 m for other appliances.
吸收钳与其他导体部分至少保持0.8m的距离,受试器具放在与地面平行的非金属支撑面上,对于落地式产品来说,支撑面的高度是0,1 m ± 0,025 ,对其他产品来说桌子的高度是 0,8 m ± 0,05 m。
The lead to be measured is placed in a straight line for a distance sufficient to accommodate the absorbing clamp, and to permit the necessary measuring adjustment of position for tuning. The clamp is placed around the lead.
测量引线应延长成一直线,以保证足够的长度容纳吸收钳,并且允许于频率协调时必要的测量位置调节。吸收钳应环绕引线放置。
作者: stone0371 时间: 2012-6-22 17:01
6.2.2 The absorbing clamp is positioned for maximum indication at each test frequency: the clamp shall be moved along the lead until the maximum value is found between a position adjacent to the appliance and a distance of about a half-wavelength from it.
NOTE The maximum may occur at a distance close to the appliance.
吸收钳的放置应使每一测量频率上知识出最大值;吸收钳应沿引线移动直到在靠近器具的位置和与器具相距半个波长的距离之间找到最大值。
注:最大值可能出现在距离器具较近的位置。
作者: stone0371 时间: 2012-6-22 17:04
6.2.3 The straight portion of the lead to be measured on should therefore be about 6 m long, this being equal to λ max/2 + 0,6 m in order to allow at any time the positioning of the absorbing clamp and a possible second clamp for additional isolation.
被测引线的拉直部分之所以6m长,是因为这个长度等于(λ max/2 + 0.6 )m,目的是允许随时为吸收钳和为了附加隔离的另一只铁氧体吸收钳的定位。
作者: stone0371 时间: 2012-6-22 17:10
这个6m,其实严格地说应该是5.6m。根据:速度=波长*频率的公式来计算。速度取光速。 V=3×108(m/s)=30×106*λ。根据该公式可以得知,波长与频率成反比,因此λmax对应的频率应该是30M,则可以λmax是10m。
因此得到5.6m。
作者: stone0371 时间: 2012-6-22 17:15
If the original lead of the appliance is shorter than the necessary length it shall be extended or replaced by a similar lead.
如果器具原来的引线短于所需的长度,应延长或用类似质量的电源引线代替。
Any plug or socket which will not pass through the absorbing clamp due to its size shall be removed or, especially in the case of controversy with regard to the banning of sales or withdrawal of a type approval the lead may be replaced by a lead of similar quality with the necessary length.
应拆去任何由于尺寸原因不能通过吸收钳的插头或插座,或者特别是在事关禁止销售或取消形式认可的争论时,引线应由所需长度的类似质量的引线代替。
NOTE λ max is the wavelength corresponding to the lowest frequency at which measurements are to be made for instance 10 m at 30 MHz.
λ max对应所要测量的最低频率点的波长,例如在30MHz时为10m。

6.2.4 If the r.f. isolation between mains supply and the input of the absorbing clamp on the side of the appliance appears to be insufficient, a fixed ferrite clamp (see CISPR 16-1-3) should be placed along the lead at a distance of about 6 m from the appliance. This improves the stability of the loading impedance and reduces extraneous noise coming from the mains supply. For more information see Clause 4 of CISPR 16-1-3.
如果在电源与在器具一侧的吸收钳之间的射频隔离不足,应在离器具6m处沿线放置一个固定的铁氧体吸收钳(见CISPR 16-1-3)。这样可以提高负载阻抗稳定性和减少来自电源的外部噪声。详见CISPR 16-1-3的第4章。

6.3 Special requirements for appliances having auxiliary apparatus connected at the end of a lead other than the mains lead
在非电源引线端连接有辅助装置的器具的特殊要求
作者: stone0371 时间: 2012-6-22 21:01
6.3.1 Measuring arrangement
6.3.1.1 Auxiliary leads normally extendible by the user, for instance with a loose end or leads fitted with a (by the user) easily replaceable plug or socket on one or both ends, shall in accordance with 6.2.3 be extended to a length of about 6 m. Any plug or socket which will not pass through the absorbing clamp due to its size shall be removed (see 6.2.3).
辅助引线通常可由使用者延长是,例如带一个自由端,或者在一端或两端装有(由使用者)容易替换的插头或插座的引线,应按6.2.3延长至大约6m的长度。应拆去任何由于尺寸原因不能通过吸收钳的插头或插座(见6.2.3)。
作者: stone0371 时间: 2012-6-22 21:04
6.3.1.2 If the auxiliary lead is permanently fixed to the appliance and to the auxiliary apparatus and:
如果辅助引线是长久地固定到器具和辅助装置的,
– is shorter than 0,25 m, measurement are not to be made on these leads;
短于0.25m的,不在该引线上测量。
– is longer than 0,25 m but shorter than twice the length of the absorbing clamp, it shall be extended to twice the length of the absorbing clamp;
长于0.25m但是短于测量吸收钳长度两倍的,应延长到吸收钳长度的两倍。
– is longer than twice the length of the absorbing clamp, measurements shall be made using the original lead.
长于吸收钳长度两倍的,使用原引线进行测量。
作者: stone0371 时间: 2012-6-22 21:09
When the auxiliary apparatus is not necessary for the operation of the main appliance (e.g. a power nozzle to a vacuum cleaner) and a separate test procedure for the auxiliary apparatus is specified elsewhere in this standard, only the lead, but not the auxiliary
apparatus, shall be connected. (However, all measurements on the main appliance in accordance with 6.3.2 are to be made.)
当辅助装置不是主体器具运行所必须的(如真空吸尘器的动力吸嘴)以及本部分的其他地方规定有辅助装置的单独试验程序是,应只接引线而不解辅助装置。(然而,按6.3.2在器具主体上所有的测试都应进行)。

6.3.2 Measurement procedure 测量程序
作者: stone0371 时间: 2012-6-26 20:07
6.3.2.1 Measurement of the disturbance power is made firstly on the mains lead of the main appliance using the absorbing clamp in accordance with 6.2. Any lead connecting the main appliance to an auxiliary apparatus is disconnected if this does not affect the operation of the appliance, or is isolated by means of ferrite rings (or an absorbing clamp) close to the appliance.
首先,在器具主体电源引线上按6.2用吸收钳进行骚扰功率的测量。如果不影响器具的运行,连接器具主体到辅助装置上的任何引线都应断开,或者通过靠近器具的铁氧体环(或吸收钳)隔离。
作者: stone0371 时间: 2012-6-26 20:11
6.3.2.2 Secondly, a similar measurement is made on each lead which is or may be connected to an auxiliary apparatus, whether or not it is necessary for the operation of the appliance; the current transformer of the clamp pointing towards the main appliance. Isolation, or disconnection of the mains lead and other leads is made in accordance with 6.3.2.1.
其次,在接到或可能接到辅助装置的每根引线上进行类似的测量,而无论器具运行时是否需要该引线;吸收钳的电流互感器指向器具主体。电源引线和其他引线的隔离或断开按6.3.2.1进行。
NOTE For short, permanently connected leads the movement of the clamp (as described in 6.2.3) is limited by the length of the lead.
注:对于短的、永久地连接的引线,吸收钳的移动受引线长度的限制(如6.2.3所述)
作者: stone0371 时间: 2012-6-26 20:13
6.3.2.3 In addition, measurement is made as above but with the current transformer of the clamp pointing towards any auxiliary apparatus, unless this auxiliary apparatus is not needed for the operation of the main appliance and a separate test procedure for it is specified elsewhere (no disconnection or r.f. isolation of other leads is of course necessary in this case).
此外,测量仍按上述方法进行,但吸收钳的电流互感器指向任一辅助装置,除非辅助装置是器具主体运行所不需要的而且另外规定有单独的试验程序(当然,在此情况下其他引线不必断开或射频隔离)。
作者: stone0371 时间: 2012-6-26 20:15
6.4 Assessment of measuring results
The measured power is derived from the maximum indicated value found at each frequency of measurement and the calibration curve of the absorbing clamp (see also the example given in Annex B of CISPR 16-1-3).
测量结果的评定
骚扰功率的测量值是在每个测量频率点找到最大指示值和吸收钳的校准曲线得出。(见CISPR16-1-3附录B中给出的例子)。

7.2.4 Thermostats
Separate as well as incorporated thermostats for the control of electric room or water heaters, oil and gas burners and the like.
温控器指的是用于控制房间电热器、电热水器、油和气体燃烧器等器具的单独的或内置式温控器。
作者: stone0371 时间: 2012-7-13 20:24
Thermostats for, or integrated in permanently installed room heating equipment intended for stationary use shall be allocated with a click rate N which is five times the click rate determined for a single, portable or removable room heater.
用于或装载预定放在固定位置使用且永久地安装的房间加热器内的温控器,其喀呖声率N为单个的,便携式的或可移式的房间加热器确定的喀呖声率的5倍。
作者: stone0371 时间: 2012-7-13 20:47
The click rate N shall be determined for the maximum operating rate stated by the manufacturer or – if sold for or together with a heater or burner – for a duty-cycle of (50 ± 10) % of this heater or burner.
喀呖声率N应由制造商说明的最大运行速率确定,或者,如果与加热器或燃烧器一起出售,以加热器或燃烧器(50±10)%的工作周期确定。
这句话应该这样理解:因为温控器一般都是有动作温度的,在最大运行速率时,是指温控器最频繁的动作状态。如果与加热器一起出售,要找到某个状态,保证温控器的动作速率时最大速率的二分之一的状态下测试。我认为这样取的是个折中的测试状态,因为在EMC测试要求中,基本的前提是要求设备工作在典型的工作状态。取最大速率的的二分之一是比较实际的工作状态的。
作者: stone0371 时间: 2012-7-13 20:50
The amplitude and duration of the disturbance shall be measured for the lowest rated current of the thermostat. For thermostats which have an acceleration resistor incorporated, the same measurements shall be performed in addition, without any separate heater connected.
骚扰幅度和骚扰持续时间应在温控器最小额定电流下测量。对于装有加速电阻器的温控器应在不接任何单独的加热器时进行同样的附加测量。
作者: stone0371 时间: 2012-7-13 20:52
When, in practice, the thermostat may be used together with inductive loads (e.g. relay,contactor) all measurements shall be performed using such a device, having the highest coil inductance used in practice.
实践中,当温控器可能与感性负载(如继电器、接触器)一起使用时,所有测量应在用实际使用时有最大线圈电感的装置上进行。
作者: stone0371 时间: 2012-7-13 20:57
In order to obtain a satisfactory measurement, it is essential that the contacts shall be operated for a sufficient number of times with a suitable load to ensure that the levels of disturbance are representative of those encountered in normal operation
为了得到令人满意的测量,用合适的负载使触点运行足够的次数是必要的,以确保能重现在正常运行中遇到的骚扰电平。

The amplitude and duration of the disturbance shall be measured for the lowest rated current of the thermostat. In the absence of a marked or a declared minimum rated current, a current equal to 10 % of the maximum rated current is used. The amplitude of no more than 25 % of the disturbances shall exceed the Lq level. For thermostats which have an acceleration resistor incorporated, the same measurements shall be performed in addition without any separate load connected.
骚扰幅度和骚扰持续时间应在温控器最小额定电流下测量,如果没有标明或声明最小额定电流,应使其等于最大额定电流的10%。不超过四分之一的骚扰的幅度可以超过Lq电平。对于装有加速电阻器的温控器应在不接任何单独加热器时进行同样的附加测量。

作者: stone0371 时间: 2012-7-16 20:54
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)。

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。

这种其他产品类标准好像没有提这个要求啊!一上来就额定电压测试,也不看电压范围引起的最大骚扰时的电压。

中档和高档个测试一次吗?选高档测试了不测中档行不行?
作者: waltektony 时间: 2012-7-17 00:02
比较正式测测试都是会先选电压然后选测试模式!固定的频点(传导0.16MHz,功率骚扰50MHz)去对比在不同电压下的读值,选择最差的电压测试,一般情况下,如电机类产品都是高电压严酷些。但最好还是选下电压比较保险!

EN 55014-1里面是又这个要求的,就像在60335-1中一样,测试的时候有0.94倍和1.15倍的电压要求。

中档和高档是各测试一次,我是这样理解的,一般情况下,根据人们的习惯,低档是很少用的,用的都是高档和中档,这样算是在实际生活中比较典型使用状态了,这和EMC测试对产品工作在典型状态的要求并不矛盾。

这个说的很符合实际情况,确实低档基本没人用。
