在实际工作使用中,一般采用下述方法来进行抑制,提高其产品的抗干扰能力。

In practical use, the following methods are usually used to suppress and improve the anti-interference ability of the products.

采用隔离变压器;选择合适的压敏电阻;在供电输出口加高频旁路电容等方法提高产品的抗干扰能力。

Adopting isolation transformer, selecting suitable varistor, adding high frequency bypass capacitor in the output port of power supply to improve the anti-interference ability of the product.

当执行继电器的绕组(感性负载)被接通和断开时。线圈中会产生一连串上升速度快,频率和幅度都相当高的尖峰脉冲电磁振荡辐射,对直流继电器绕组通常采用以下方法来减少干扰:

When the winding (inductive load) of the relay is switched on and off. In the coil, a series of spike pulse electromagnetic oscillation radiation with high rising speed, frequency and amplitude are produced, and the DC relay windings are usually used to reduce the interference:

在线圈两端反并二极管或RC器件,如控制触点对交流感性负载的控制,也可考虑在触点并接RC 器件,从而能对触点在通断时产生的干扰进行有效的吸收。

The reverse diode or RC device on both sides of the loop, such as the control contact to control the AC inductive load, can also be considered in the contact and connected to the RC device, so as to effectively absorb the interference produced by the contact on and off.

屏蔽能有效地抑制通过空间传播的电磁干扰,一则可限制内部产生的电磁能辐射出去;二则可防止外来 辐射进入,在对内部电子线路采用整体屏蔽措施,也可对内部信号线采用屏蔽线,增强其抗干扰能力。

The shield can effectively suppress electromagnetic interference through space propagation, electromagnetic can be generated within the limit can radiate; two can prevent external radiation into, in the overall shielding measures of internal electronic circuit, but also can be used for shielding line internal signal lines, enhance its anti-interference ability.
