NA2671 Series Pointer Insulation Resistance Tester     NA2671指針式絕緣電阻測試儀

產(chǎn)品簡介

隨著我國電力工業(yè)的快速發(fā)展，電氣設(shè)備預(yù)防性實(shí)驗(yàn)是保障電力系統(tǒng)安全運(yùn)行和維護(hù)工作中的一個重要環(huán)節(jié)。絕緣診斷是檢測電氣設(shè)備絕緣缺陷或故障的重要手段。絕緣電阻測試儀是測量絕緣電阻的儀表。1990年5月批準(zhǔn)實(shí)施的JJG662-89《絕緣電阻表（兆歐表）》已把它作為強(qiáng)制的儀表。目前，電氣設(shè)備（如變壓器、發(fā)電機(jī)等）朝著大容量化、高電壓化、結(jié)構(gòu)多樣化及密封化的趨勢發(fā)展。這就需要絕緣電阻測試儀本身具有容量大、抗干擾能力強(qiáng)、測量指標(biāo)多樣化、測量結(jié)果準(zhǔn)確、測量過程簡單并迅速、便于攜帶等特點(diǎn)。

南澳電氣生產(chǎn)的指針式絕緣電阻測試儀采用薄形張絲表頭、多種電壓等級輸出、容量大、抗干擾強(qiáng)、交直流兩用(C型)、操作簡單、具有時間提示功能。是測量變壓器、互感器、發(fā)電機(jī)、高壓電動機(jī)、電力電容、電力電纜、避雷器等絕緣電阻的理想測試儀器。

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

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 display for easy reading.

(4) ABS plastic 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.
