電涌保護器的重要參數有哪些？
電涌保護器廠家生產的電涌保護器種類主要分為三種：電壓開關型、限壓型和復合型。開關電源浪涌保護器是一種浪涌保護器，在沒有浪涌時具有高阻抗，在有浪涌時可以立即轉換為低阻抗。其常用元件有放電間隙、氣體放電管、晶閘管和三端兩端晶閘管開關元件，又稱“短路浪涌保護器”。
參數1、電涌保護器的種類
限壓浪涌保護器在沒有浪涌時具有較高的阻抗，但隨著浪涌電流和電壓的增加，其阻抗會不斷降低。其常用的非線性元件是壓敏電阻和抑制二極管，也稱為“鉗位浪涌保護器”
復合型電涌保護器由電壓開關型和限壓型元件組成。根據所施加電壓的特性，其特性可以表示為電壓開關型、電壓限制或兩者兼而有之。
參數 2，標稱放電電流 （In）
標稱放電電流是指流過電涌保護器（SPD）的8/20峰值電流。駿合電子電力浪涌保護器的標稱放電電流根據保護等級而變化。詳情請參閱產品列表頁面。
參數 3，沖擊電流 （Iimp）
由電流峰值Ipeak、充電量Q和比能量W/R確定，是10/350波I型實驗的浪涌保護器的分類。
參數 4.最大放電電流（Imax）
最大放電電流流過電涌保護器，峰值為8/20波型電流。不同級別的電源浪涌保護器的最大放電電流不同。詳情請參閱產品列表頁面。
參數5、最大連續工作電壓（Uc）
最大連續工作電壓是交流電壓或直流電壓的最大有效值tage 允許永久施加到電涌保護器上。其值等于額定電壓。
參數6、電壓保護等級（Up）
電壓保護水平是表征電涌保護器端子之間電壓的性能參數，其值可以從首選值列表中選擇。
參數7、殘余壓力
殘余電壓是指放電電流流過電涌保護器時，電涌保護器端子之間的峰值電壓。
參數 8、外殼防護等級
電涌保護器的外殼防護等級是指外殼為防止接觸危險部位、防止外部固體異物、防止水進入外殼而提供的保護程度。

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.
