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）》已把它作为强制的仪表。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。

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

Also called name

The Characteristics of the products

(1) The instrument is used to do insulation test: when the voltage is 500V, the maximum tested value will up to 20GΩ; when the voltage is 1000V, the value will up to 40GΩ; when the voltage is 2500V, the value will up to 100GΩ.

(2) When rated output voltage of NA2501 tester continuously load, the resistance can be as low as 4MΩ/8MΩ/20MΩ, which makes the instrument can measure the low insulation resistance accurately.

(3) Double scale indication can be converted automatically, colorful LED disy for easy reading.

(4) ABS stic casing and portable design with anti-interference ability, compact structure, attractive appearance.

(5) The instrument uses ultra-thin sheets silk headers, seismic resistance.

(6) AC-DC dual-use, built-in rechargeable battery and intelligent charging module, ensuring high output power(C type).

(7) It is an ideal tester to measure insulation resistance of these equipments such as transformer, instrument transformer, generator, HV motor, power capacitors, power cables, arrester, etc.
