NA23雷电冲击峰值电压表 NA23 Lightning impact peak voltage meter
产品别名
NA23型冲击峰值电压表，冲击脉冲峰值电压表，冲击峰值电流表，冲击峰值表，脉冲峰值电压表，脉冲峰值电流表
设备简介
NA23型冲击峰值电压表，用于测量和储存冲击电压峰值、冲击电流峰值以及其它单次脉冲峰值。内部的一个计算单元可使分压器高压侧的峰值以kV为单位直接显示出来。显示范围从 0.1kV至 16000kV。
该装置是为了高压试验室的使用而专门设计的。采用特殊的布线、屏蔽、滤波以及过电压保护线路使电磁干扰高度衰减。
测量范围
通过测量电缆，该设备连接至冲击电压分压器(电阻型或电容型设备)的低压臂或大电流分流器上。对于测量分压器(分流器), 冲击峰值电压表将引入一个2MΩ∥39pf的负载。如果需要，例如在电阻型冲击分压器的情况，可将75Ω(或50Ω)的匹配电阻加在该表的两个输入端之一。该装置允许输入的zui大脉冲电压峰值为1600V。测量值以5位数字直接显示，单位为kV。
该装置不同于目前常用的冲击峰值表的特点是：测量电压量程无需手动切换,而由装置自动切换。正负极性在显示屏上自动显示。

NA23 Type Impulse Peak-Voltmeter
Also name
NA23 impact peak voltage table, the impact pulse peak voltmeter, the impact of the peak ammeter, the impact of the peak table, the peak pulse voltage meter, pulse peak ammeter
Introduce of NA23
NA23 Impact Peak Voltmeter for measuring and storing impulse voltage peaks, peak impulse currents, and other single pulse peaks. An internal calculation unit allows the peak of the voltage divider to be displayed directly in units of kV. Display range from 0.1kV to 16000kV.
The tester designed for use with high pressure laboratories. Use of special wiring, shielding, filtering and over-voltage protection circuit to a high degree of attenuation of electromagnetic interference.
Measuring range
The measuring cable is connected to a low voltage arm or a high current shunt of an impulse voltage divider (resistive or capacitive type device). For measuring the voltage divider (shunt), the impulse peak voltmeter will introduce a load of 2MΩ // 39pf. If necessary, for example, in the case of a resistive shock divider, a 75Ω (or 50Ω) matching resistor can be added to one of the two inputs of the table. The maximum permissible pulse voltage of the device is 1600V. Measured values are displayed directly in 5 digits, in kV.
The device is different from the current commonly used impact peak table is characterized by: measuring voltage range without manual switching, and by the device automatically switch. Positive and negative polarity is automatically displayed on the display.
