NA23雷電脈沖沖擊峰值電壓表   NA23 Lightning impact peak voltage meter

產品別名

NA23型沖擊峰值電壓表，沖擊脈沖峰值電壓表，沖擊峰值電流表，沖擊峰值表，脈沖峰值電壓表，脈沖峰值電流表

設備簡介

NA23型沖擊峰值電壓表，用于測量和儲存沖擊電壓峰值、沖擊電流峰值以及其它單次脈沖峰值。內部的一個計算單元可使分壓器高壓側的峰值以kV為單位直接顯示出來。顯示范圍從 0.1kV至 16000kV。

該裝置是為了高壓試驗室的使用而專門設計的。采用特殊的布線、屏蔽、濾波以及過電壓保護線路使電磁干擾高度衰減。

測量范圍

通過測量電纜，該設備連接至沖擊電壓分壓器(電阻型或電容型設備)的低壓臂或大電流分流器上。對于測量分壓器(分流器), 沖擊峰值電壓表將引入一個2MΩ∥39pf的負載。如果需要，例如在電阻型沖擊分壓器的情況，可將75Ω(或50Ω)的匹配電阻加在該表的兩個輸入端之一。該裝置允許輸入的最大脈沖電壓峰值為1600V。測量值以5位數字直接顯示，單位為kV。

該裝置不同于目前常用的沖擊峰值表的特點是：測量電壓量程無需手動切換,而由裝置自動切換。正負極性在顯示屏上自動顯示。

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.
