包含单个保护元件或者组合保护电路，又按安装技术条件而集成一体的组合件（导轨安装式、电源插座式、适配器）称作放电器。

Containing a single element or combination protection circuit, and according to the installation technical conditions and integrated assembly (guide installation type, power socket type, adapter) called the discharger.

　　几乎在所有情况下的过压保护，至少应分成两级。如电源，各个只包含一级保护的放电器，可安装在不同的位置，同一放电器中也可能包含多级保护。为了达到有效的过压保护，人们将需要保护的范围，按不同的电磁兼容性分区，这个保护范围，包括从闪电保护区0，过压保护区1至3，直到干扰电压保护区具有更高的序号。

In almost all cases, the over-voltage protection should be at least two levels. If the power supply, each one containing the primary protection of the discharger, can be installed in different location, the same discharge appliance also may contain multistage protection. In order to achieve effective overvoltage protection, people will need to protect the scope of the electromagnetic compatibility according to different partition, the scope of protection, including from the lightning protection zone 0, over-voltage protection area 1 to 3, until the interfering voltage reserves have a higher number.

　　设置电磁兼容性保护区0到3，是为了避免因高能耦合而损坏设备。而序号更高的电磁兼容性保护则为防止信息失真和信息丢失而设置的。保护区的序号越高，预期的干扰能量和干扰电压电平越低。需要保护的电气和电子设备安装在一个十分有效的保护圈内，这样的保护圈可以针对单个的电子设备，也可以是一个装有多个电子设备的空间，甚至一整栋楼，所有穿过通常具有空间屏蔽的保护圈的电线，在接到该保护圈的外围设备的同时接过压保护放电器。

Set the electromagnetic compatibility reserve 0 to 3 to avoid damaging the equipment due to high energy coupling. The higher order electromagnetic compatibility protection is set up to prevent information distortion and loss of information. The higher the number, the lower the expected interference energy and disturbance voltage. Need to protect the electrical and electronic equipment installation, in a very effective skirts like skirts can be on a single electronic devices, or it can be a space with multiple electronic devices, and even the whole building, all through the shielding wire's skirts, usually has a space in the skirts of over-voltage protection discharger of peripheral devices at the same time.

　　放电器的选择取决于各个电路和参数。放电器的工作电压以安装在此电路中所有部件的额定电压为准，而要达到的剩余电压则根据安装在此电路中所有部件的耐压强度确定。耐压强度按1. 2/50us脉冲测试。并联时，即在有源导线和地之间接上放电器时，则无需注意其额定电流，因为额定电流并不通过放电器。

The choice of the appliance depends on the circuit and the parameters. Put the working voltage of electric equipment to install all parts in the circuit of rated voltage, and to achieve the residual voltage according to the installation of all components in the circuit to determine compression strength. Compressive strength press 1. 2/50us pulse test. In parallel, when an electrical appliance is placed between a source conductor and the earth, it is not to be noticed that the current is rated, because the rated current is not by the discharger.

　　电路装有串联放电器的情况下，必须注意其额定电流，在数据传输率很高的电路中，放器的衰减起着决定性的作用。

Circuit with a series of discharger, must pay attention to its rated current, in the circuit of data transfer rate is very high, attenuation of put plays a decisive role.
