產(chǎn)品概述 Product Overview
HLY600A大電流微歐計(jì)(回路電阻測試儀)根據(jù)中華人民共和國新的電力執(zhí)行標(biāo)準(zhǔn)DL/T845.4-2004,采用高頻開關(guān)電源技術(shù)和數(shù)字電路技術(shù)相結(jié)合設(shè)計(jì)而成。它適用于開關(guān)控制設(shè)備回路電阻的測量。其測試電流采用國家標(biāo)準(zhǔn)推薦的直流100A和200A??稍陔娏?00A的情況下直接測得回路電阻,也可以在電流200A、400A或600A的情況下直接測得回路電阻,最后的測試結(jié)果都用數(shù)字顯示出來。該儀器測量準(zhǔn)確、性能穩(wěn)定,符合電力、供電部門現(xiàn)場高壓開關(guān)維修和高壓開關(guān)廠回路電阻測試的要求。
The HLY600A high-current micro-ohmmeter (loop resistance tester) is designed based on the new power execution standard DL/T845.4-2004 of the People's Republic of China,utilizing a combination of high-frequency switching power supply technology and digital circuit technology。It is suitable for measuring the loop resistance of switch control equipment. Its test currents adopt the DC 100A and 200A recommended by national standards。 It can directly measure the loop resistance at a current of 100A,as well as at 200A, 400A, or 600A。The final test results are displayed digitally。This instrument provides accurate measurements and stable performance, meeting the requirements of on-site high-voltage switch maintenance by power and electricity supply departments,as well as loop resistance testing in high-voltage switch factories。
