NAPR Series no PD?Pulse Divider ??NAPR高精度無局放分壓器

產品簡介?

NAPR系列無局放分壓器又稱耦合電容器，主要用于無局放測試系統測量交流電壓或***局放電壓信號，該系列分壓器與普通分壓器比較，有以下幾個不同點：

1、都可以測量高壓電壓，但普通分壓器不能測量無局放的高壓電壓；

2、普通分壓器一般電容量較小（小于500pF），而NAPR系列電容量較大，一般在600-1000pF；

3、普通分壓器為干式介質，體積比較小，重量比較輕，測量準確度一般優于NAPR系列；

4、普通分壓器一般單獨使用，NAPR系列分壓器一般與無局放電源一起配合使用；

Product introduction

NAPR?pulse divider is high-voltage measuring systems with under-damping and potential shielding. Mainly used for measuring for light wave, including light fullwave,8/20uswave and other light waveform. It’s?a special voltage divider for light waveform. Simple to operate, intuitive display, high precision, small in size, light in weight. It’s ideal high-voltage measuring equipment for Grid primary equipment testing(such as Zinc oxide lightning arrester waves steeptesting,voltage transformer lighting full-wave testing, high-voltage switch lighting fill-wave testing, substation main transformer testing, high-voltage GIS testing,etc.), substation,high-voltageelectrical equipment factory and high-voltage testing laboratory and other relative departments.

The parameters of the products

1, Voltage level: AC: 50 kV-2000kV (Able to withstand the impact of rates 110% voltage peak value )

2, Responding time:<120ns (special requirements can be customized)

3, Impact of voltage waveform:

Lightning impulse full wave (referred as to lightning full-wave lightning) the main parameters is peak UP, pre-wave time T1, half peak time T2, the pre-wave of standardlightningfull-wave time ?is T1 = 1.2us

Half peak value time is T2 = 50us.

In order to obtain highly accurate testing data, it is recommended to adopt US Tektronix which more than 200M oscilloscope, while the other technical specifications shouldmeetthe high-voltage lightning wave measurement requirements.

4, Accuracy: AC: 3.0%

5, Insulating medium: Imported capacitor oil

6, Environmental conditions:

??Temperature: 0℃~ 45℃

??Humidity:<85% RH

7, Divided voltage ratio: 1000:1 or (according to customer requirements)
