The HM6080 High-Voltage Switch Comprehensive Characteristics Tester, also known as a mechanical characteristics tester, is designed in accordance with the latest edition of the "High-Voltage AC Circuit Breakers" standard (GB1984-2003), with reference to Part 3 of the Chinese power industry standard "General Technical Specifications for High-Voltage Test Equipment," and in compliance with DL/T846. 3-2004. It is used to test the mechanical dynamic characteristic parameters of high-voltage circuit breakers under various operating conditions, including oil-deficient, oil-overflow, vacuum, and sulfur hexafluoride (SF6) environments, to meet the testing requirements for various types of circuit breakers.
