工业生产中广泛应用高频感应加热设备,为了防止射频电磁场对人体健康的影响采用屏蔽防护技术较好。常用的电磁屏蔽分为两大类,一为主动场屏蔽,主要是用来防止场源对外的影响;二为被动场屏蔽,屏蔽体用来防止外部场源对内的影响。工业高频设备大多数属于主动场屏蔽。现将常用的Gp—100—C_3型高频感应加热设备的屏蔽情况及效果为例简述如下。
Widely used in industrial production of high-frequency induction heating equipment, in order to prevent the impact of radio frequency electromagnetic fields on human health using shielding technology is better. Commonly used electromagnetic shielding is divided into two categories, one for the active field shielding, mainly to prevent the impact of external field sources; two passive field shielding, shield to prevent external field source on the internal impact. Most industrial high-frequency equipment belongs to the active field shielding. Now commonly used Gp-100-C_3-type high-frequency induction heating equipment and the effectiveness of the shield as an example is as follows.
