產品概述 Product Overview
HLY600A大電流微歐計（回路電阻測試儀）根據中華人民共和國新的電力執行標準DL/T845.4-2004，采用高頻開關電源技術和數字電路技術相結合設計而成。它適用于開關控制設備回路電阻的測量。其測試電流采用國家標準推薦的直流100A和200A。可在電流100A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，最后的測試結果都用數字顯示出來。該儀器測量準確、性能穩定，符合電力、供電部門現場高壓開關維修和高壓開關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。
