Electric field emission reduction apparatus
摘要：
Electrical apparatus comprises antenna means (200) for directing towards an electric field source to detect the electric field (E) to be reduced. The antenna means (200) is connected to amplifier means (210) for generating an output signal in response to an input signal from the antenna means (200). The output signal is in anti-phase to the input signal. Radiator means (140) is connected to the amplifier means (210) for radiating an cancelling electric field (E') in anti-phase to the electric field (E) from the source (100) in response to the output signal from the amplifier (210) to at least partially cancel reduce the electric field from the source (100). The antenna means (200), when directed towards the source (100), is positioned relative to the radiator means (140) and the source (100) to detect both the cancelling electric field (E') from the radiator means (140) and the electric field (E) from the source (100). The input signal produced by the antenna means (200) is thus derived from the sum of the electric field (E) to be reduced from the source (100) and the cancelling electric field (E') from the radiator (140).
摘要（中）：

电气设备包括用于指向电场源以检测要减小的电场（E）的天线装置（200）。 天线装置（200）连接到放大器装置（210），用于响应于来自天线装置（200）的输入信号而产生输出信号。 输出信号与输入信号反相。 散热器装置（140）连接到放大器装置（210），用于响应于来自放大器的输出信号，从源极（100）辐射与电场（E）反相的抵消电场（E'） （210）至少部分地抵消减少源（100）的电场。 当指向源（100）时，天线装置（200）相对于辐射器装置（140）和源（100）定位，以检测来自散热器装置（140）的消除电场（E'）， 和源（100）的电场（E）。 因此，由天线装置（200）产生的输入信号是从源极（100）减小的电场（E）和来自散热器（140）的消除电场（E'）之和得出的。
