NA2671 Series Pointer Insulation Resistance Tester NA2671指针式绝缘电阻测试仪

产品简介

随着我国电力工业的快速发展，电气设备预防性实验是保障电力系统安全运行和维护工作中的一个重要环节。绝缘诊断是检测电气设备绝缘缺陷或故障的重要手段。绝缘电阻测试仪是测量绝缘电阻的专用仪表。1990年5月批准实施的JJG662-89《绝缘电阻表（兆欧表）》已把它作为强制检定的仪表之一。目前，电气设备（如变压器、发电机等）朝着大容量化、高电压化、结构多样化及密封化的趋势发展。这就需要绝缘电阻测试仪本身具有容量大、抗干扰能力强、测量指标多样化、测量结果准确、测量过程简单并迅速、便于携带等特点。

南澳电气生产的指针式绝缘电阻测试仪采用超薄形张丝表头、多种电压等级输出、容量大、抗干扰强、交直流两用(C型)、操作简单、具有时间提示功能。是测量变压器、互感器、发电机、高压电动机、电力电容、电力电缆、避雷器等绝缘电阻的理想测试仪器。

产品特性

1）指针式绝缘电阻测试仪的绝缘测试在500V最高可测20GΩ, 在1000V最高可测40GΩ, 在2500V最高可测100GΩ。

2）额定的输出电压保持在对指针式绝缘电阻测试仪负载电阻可低至4MΩ/8MΩ/20MΩ，这使得仪表能够精确测量较低的绝缘阻抗。

3）自动转换的高低范围双刻度指示, 彩色刻度易于读识, 并且有LED显示相应色彩。

4）整机采用ABS塑料机壳便携式设计，具有抗干扰能力强、结构紧凑、外观精美。

5）指针式绝缘电阻测试仪采用超薄型张丝表头，抗震能力强。

6）交直流两用，内置可充电池和智能充电模块，整机输出功率大（C型）。

7）指针式绝缘电阻测试仪是测量变压器、互感器、发电机、高压电动机、电力电容、电力电缆、避雷器等绝缘电阻的理想测试仪器。

Product introduction

With the rapid development of National power industry, electrical equipment preventive experiment is an important part in protecting the safety operation of power system and maintenance. Insulation diagnosis is an important method to detect insulation defects or failure. Pointer insulation resistance tester is the special instrument to measure insulation resistance. JJG662-89 "insulation resistance meter (megger)" approved in May 1990 requires that insulation resistance meter is one of compulsory verification instruments. Nowadays the development trend of electrical equipment (such as transformers, generators, etc.) is that high capacity, high voltage, diversified structure and better seal. So insulation resistance meter (pointer) itself must have the characteristics such as large capacity, strong anti-interference ability, diversified measurement indexes, accurate measurement results, easy and fast measurement process, easy to carry and so on. The instrument produced by our company is equipped with ultra-thin taut suspension meter. It is an ideal tester to measure insulation resistance of these equipment such as transformer, instrument transformer, generator, HV motor, power capacitors, power cables, arrester, etc
