电涌保护器的重要参数有哪些？
电涌保护器厂家生产的电涌保护器种类主要分为三种：电压开关型、限压型和复合型。开关电源浪涌保护器是一种浪涌保护器，在没有浪涌时具有高阻抗，在有浪涌时可以立即转换为低阻抗。其常用元件有放电间隙、气体放电管、晶闸管和三端两端晶闸管开关元件，又称“短路浪涌保护器”。
参数1、电涌保护器的种类
限压浪涌保护器在没有浪涌时具有较高的阻抗，但随着浪涌电流和电压的增加，其阻抗会不断降低。其常用的非线性元件是压敏电阻和抑制二极管，也称为“钳位浪涌保护器”
复合型电涌保护器由电压开关型和限压型元件组成。根据所施加电压的特性，其特性可以表示为电压开关型、电压限制或两者兼而有之。
参数 2，标称放电电流 （In）
标称放电电流是指流过电涌保护器（SPD）的8/20峰值电流。骏合电子电力浪涌保护器的标称放电电流根据保护等级而变化。详情请参阅产品列表页面。
参数 3，冲击电流 （Iimp）
由电流峰值Ipeak、充电量Q和比能量W/R确定，是10/350波I型实验的浪涌保护器的分类。
参数 4.最大放电电流（Imax）
最大放电电流流过电涌保护器，峰值为8/20波型电流。不同级别的电源浪涌保护器的最大放电电流不同。详情请参阅产品列表页面。
参数5、最大连续工作电压（Uc）
最大连续工作电压是交流电压或直流电压的最大有效值tage 允许永久施加到电涌保护器上。其值等于额定电压。
参数6、电压保护等级（Up）
电压保护水平是表征电涌保护器端子之间电压的性能参数，其值可以从首选值列表中选择。
参数7、残余压力
残余电压是指放电电流流过电涌保护器时，电涌保护器端子之间的峰值电压。
参数 8、外壳防护等级
电涌保护器的外壳防护等级是指外壳为防止接触危险部位、防止外部固体异物、防止水进入外壳而提供的保护程度。

What are the important parameters of the surge protection device?
The types of surge protectors produced by surge protection manufacturers are mainly divided into three types: voltage switch type, voltage limit type and composite type. The switching power surge protector is a surge protector that has a high impedance when there is no surge and can be transformed into a low impedance immediately when there is a surge. Its common components are a discharge gap, gas discharge tube, thyristor and three-terminal two-way Thyristor switching element, also known as a "short-circuit surge protector".
Parameter 1, the types of surge protector
The voltage-limiting surge protector has high impedance when there is no surge, but as the surge current and voltage increase, its impedance will continue to decrease. Its commonly used non-linear components are varistors and suppression diodes, also called "Clamping surge protector"
The composite type surge protector is composed of voltage switching type and voltage limiting type components. Its characteristics can be expressed as voltage switching type, voltage limitation or both according to the characteristics of the applied voltage.
Parameter 2, Nominal discharge current (In)
The nominal discharge current refers to the 8/20 peak current flowing through the surge protector (SPD). The nominal discharge current of Junhe electronic power surge protector varies according to the protection level. For details, please refer to the product list page.
Parameter 3, impulse current (Iimp)
Determined by the current peak value Ipeak, the charge quantity Q and the specific energy W/R, it is the classification of the surge protector of the 10/350 wave type I experiment.
Parameter 4. Maximum discharge current(Imax)
The maximum discharge current is flowing through the surge protector, which has a peak value of 8/20 wave type current. The maximum discharge current is different for different levels of the power surge protector. For details, please refer to the product list page.
Parameter 5, the maximum continuous working voltage(Uc)
The maximum continuous working voltage is the maximum effective value of AC voltage or DC voltage that is allowed to be permanently applied to the surge protector. Its value is equal to the rated voltage.
Parameter 6, voltage protection level (Up)
The voltage protection level is a performance parameter that characterizes the voltage between the terminals of the surge protector, and its value can be selected from a list of preferred values.
Parameter 7, residual pressure
Residual voltage refers to the peak voltage between the terminals of the surge protector when the discharge current flows through it.
Parameter 8, shell protection level
The shell protection level of a surge protector refers to the degree of protection provided by the shell to prevent dangerous parts from being touched, to prevent external solid foreign objects, and to prevent water from entering the shell.
