    • PURPOSE:To prevent the occurrence of the voltage higher than the absolute max. rated voltage when a high speed discharge protector is operated, by connecting one power source system discharge loop to another power source system through a diode. CONSTITUTION:A high speed discharge protector is composed of a discharge tube 11, current limiting resistors 17-20, diode 23, current detecting circuit 21 and a trigger drive 22. The resistors 19, 20 are connected in series to a capacitor 12 for the purpose of limiing the arcing current occurring between a cathode and a body, while the resistors 17, 18 are connected in series to a capacitor 15 for the purpose of limiting the arcing current occurring between a collector and the body. The discharge tube 12, capacitor 12 and the resistor 20 will constitute one loop while the discharge tube 11, resistors 18, 20, capacitor 15 and the diode 23 will constitute another loop.
    • 目的:防止电压高于绝对最大值的发生。 通过一个二极管将一个电源系统放电回路连接到另一个电源系统,高速放电保护器工作时的额定电压。 构成:高速放电保护器由放电管11,限流电阻器17-20,二极管23,电流检测电路21和触发驱动器22组成。电阻器19,20串联连接到电容器12,用于 为了限制发生在集电体和主体之间的电弧电流,电阻器17,18与电容器15串联连接,因此限制了在阴极和体之间产生的电弧电流的目的。 放电管12,电容器12和电阻器20将构成一个环路,而放电管11,电阻器18,20,电容器15和二极管23将构成另一环路。
