7.3.6.3.2 Experimental kits  试验型玩具

A few set-ups of the experiments which are specified by the manufacturer for the normal intended use are subjected to EMC tests. The selection is made by the manufacturer, but from those with the highest interference potential.

由制造商规定的用于正常预期使用的一些试验组件应进行EMC测试。由制造商选择那些具有潜在的最大骚扰的试验组件。

7.3.7 Miscellaneous equipment and appliances ：其他设备和器具


NOTE Limits in the frequency range 30 MHz to 1 000 MHz are not applicable to the devices quoted in 7.3.7.1 to 7.3.7.3, causing only discontinuous disturbance (see 4.2.1).

注：30MHz-300MHz频段内的骚扰功率限值不适用于7.3.7.1至7.3.7.3涉及的装置，（因为）其只引起断续骚扰（见4.2.1）

7.3.7.1 Time switches not incorporated in equipment or appliances

定时开关不装在设备或器具内

The switch is adjusted to maximize the value of n2 (the number of switching operations – see7.4.2.3). The load current shall be 0,1 of the maximum rated value, and unless otherwise specified by the manufacturer, the load shall consist of incandescent lamps.

开关应调节到使n2值（开关操作数-见7.4.2.3）最大。负载电流应为最大额定电流的0.1倍，且除非制造商有另外规定，负载应有白炽灯组成。

If the conditions in 4.2.3.3 "instantaneous switching" are satisfied, there is no limit on the amplitudes of the clicks produced.

如果4.2.3.3规定的“瞬时开关”的条件满足，喀呖声的幅度没有限值限制。

For switches employing a manually operated "on" and automatic "off", the average "on" time (t1 seconds) shall be determined from three successive operations while the switch is adjusted to maximize the value of n2. A rest period of 30 s shall be allowed. The time for a complete cycle is (t1 + 30) s, thus the click rate N = 120/(t1 + 30).

对于手动”接通“自动”断开“的开关，平均“接通”时间（t1，单位s）用由将开关调节到使n1值最大三个完整操作确定。应允许有30s的间歇时间。真个周期时间为(t1 + 30) s，这样喀呖声率N= N = 120/(t1 + 30).

7.3.7.2 Electric fence supply units ：电栅栏供电装置

When measuring the disturbance voltage at the fence terminals of the electric fence energizer, the fence wire shall be simulated by a series RC circuit comprising a 10 nF capacitor (surge voltage at least equal to the no-load output voltage of the electric fence
energizer) and a 250 Ω resistor (the 50 Ω in parallel with 50 μH incorporated in the artificial mains V-network provides the balance of the required 300 Ω load resistance) connected as shown in Figure 6.

在电栅栏激发器的栅栏端进行骚扰电压测量时，栅栏线应由串联的RC电路模拟。该电路由10nf电容器（浪涌电压至少等于电栅栏激发器的空载输出电压）和250Ω的电阻器（装在V型人工点冤枉路颞部的50Ω电阻并联50uH的电感提供所要求的300Ω的负载阻抗的平衡）组成，并按图6所示连接。

The limits for electric fence supply units apply to the mains terminals and to the output terminal of the supply unit. A correction factor of 16 dB shall be added to the measured values on the output terminals according to the voltage division resulting from the use of the fence equivalent circuit from the 250 Ω resistor in series with the 50 Ω impedance of the artificial mains V-network (see also item 5 of the legend of Figure 6).

电栅栏供电装置的限值适用于供电装置的电源端子和输出端子。由于使用250Ω电阻器串联V型人工电源网络50Ω阻抗的电栅栏等效电路导致分压，应在输出端子的测量值上加上一个16dB的校准因子（见图6的图例第5项）。

The leakage resistance of the fence wire is represented by a resistor of 500 Ω placed in parallel to the series circuit.

电栅栏阴险的泄漏电阻由于串联电路并联的500Ω电阻器替代。

When measuring, the appliance shall be operated in the normal position with a maximum inclination of 15° from the vertical position

测量时，器具应在正常位置与垂直位置最大成15°倾斜角运行。

The controls accessible without tools shall be set to the position of maximum disturbance.

不用工具即可触及的控制器应设定在最大骚扰的位置。

Electric fence energizers designed to be operated with a.c. or d.c. shall be tested with both kinds of supply。

设计能用交流或直流运行的电栅栏应在两种电源下进行测试。

The earth terminal of the fence circuit shall be connected to the earth terminal of the artificial mains V-network. If the terminals of the fence circuit are not clearly marked, they shall be earthed in turn.

栅栏电路的接地端子应街道V型人工电源网络的接地端子上。如果栅栏电路的段子没有明确标出，则应轮流接地。

NOTE In order to avoid damage to the r.f. input of the measuring receiver by the high energy pulses of the electric fence unit, it may be necessary to insert an attenuator before the r.f. input.

注：为了避免电栅栏部件的高能脉冲损坏测量接受的射频输入端，在射频输入之前可能需要接入衰减器。
