產品簡介

隨著我國電力工業的快速發展，電氣設備預防性實驗是保障電力系統安全運行和維護工作中的一個重要環節。絕緣診斷是檢測電氣設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專用儀表。1990年5月批準實施的JJG662-89《絕緣電阻表（兆歐表）》已把它作為強制檢定的儀表之一。目前，電氣設備（如變壓器、發電機等）朝著大容量化、高電壓化、結構多樣化及密封化的趨勢發展。這就需要絕緣電阻測試儀本身具有容量大、抗干擾能力強、測量指標多樣化、測量結果準確、測量過程簡單并迅速、便于攜帶等特點。

南澳電氣生產的指針式絕緣電阻測試儀采用超薄形張絲表頭、多種電壓等級輸出、容量大、抗干擾強、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、發電機、高壓電動機、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 partinprotecting the safetyoperation of power system and maintenance. Insulation diagnosis is an important method to detect insulation defects or failure. Pointer insulation resistance tester isthespecial instrument to measureinsulation resistance. JJG662-89 "insulation resistance meter (megger)" approved in May 1990 requires that insulation resistance meter is one of compulsoryverificationinstruments. Nowadays thedevelopment trend of electrical equipment (such as transformers, generators, etc.) is that high capacity, high voltage, diversified structure and better seal. Soinsulationresistance meter (pointer)itself must have the characteristics such as large capacity, strong anti-interference ability, diversified measurement indexes, accurate measurement results, easyand fastmeasurement process, easy tocarry 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 resistanceof theseequipment 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 upto20GΩ; when the voltage is 1000V, thevalue 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 lowas4MΩ/8MΩ/20MΩ, which makes the instrument can measurethe 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).
