南澳电气专业生产NARP高精度无局放分压器无感脉冲分压器

产品简介

NARP系列无局放分压器又称耦合电容器，主要用于无局放测试系统测量交流电压或采集局放电压信号，该系列分压器与普通分压器比较，有以下几个不同点：

1、都可以测量高压电压，但普通分压器不能测量无局放的高压电压；

2、普通分压器一般电容量较小（小于500pF），而NARP系列电容量较大，一般在600-1000pF；

3、普通分压器为干式介质，体积比较小，重量比较轻，测量准确度一般优于NARP系列；

4、普通分压器一般单独使用，NARP系列分压器一般与无局放电源一起配合使用；

Product introduction

NARP pulse divider is high-voltage measuring systems with under-damping and potential shielding. Mainly used for measuring for light wave, including light full wave,8/20us wave 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 steep testing, voltage transformer lighting full-wave testing, high-voltage switch lighting fill-wave testing, substation main transformer testing, high-voltage GIS testing,etc.), substation, high-voltage electrical equipment factory and high-voltage testing laboratory and other relative departments.

Also called name

NARP Series pulse impulse divider, pulse divider

The Characteristics of the products

Adopting imported fill material and realizing highly stable, the inside adopt highly precision resistance and low tangent capacity, partial discharge. Small size, light weight, ans easy to take.

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 standard lightning full-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 should meet the 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)

Power supply: AC110V/115V/120V/127V/220V/230V/240V optional

Input frequency: 50Hz/60Hz optional

Note: Our users can select the corresponding power which based on their local supply voltage and frequency, and we will confirm it before the delivery (or inform us that the goods will be used in which country advance)
