High-Voltage Switch Mechanical Characteristics Tester with Graphite Contacts

The HM6081 High-Voltage Switch Mechanical Characteristics Tester is a professional tool for high‑voltage switch performance testing.It accurately checks mechanical features of low‑oil, high‑oil, vacuum and SF6 high‑voltage circuit breakers of different voltage levels.

• Excellent anti‑interference performance – It works reliably and gives accurate readings even when used in a 500kV substation.
• Universal speed‑measuring sensors – Comes with linear stroke sensors and rotary sensors. They are quick and easy to set up.
• One‑operation data collection – After a single switching operation, you get all mechanical characteristic data and the corresponding waveform graphs.
• Wide compatibility – Works with mechanical characteristic tests for all makes of SF6 switches, GIS equipment, vacuum switches, and oil switches, both domestic and international.
• Large storage – The main unit can store up to 2,000 sets of on‑site open/close test results. A built‑in real‑time clock records the test date and time for easy file management.
• USB transfer – Supports direct saving and transfer of data via USB flash drive.
• Easy‑to‑read display – Large, wide‑temperature backlit LCD shows all data and graphs in Chinese. LCD contrast is adjusted electronically, and the setting stays even after power‑off.
• Simple menu and built‑in printer – Easy Chinese menu operation. The built‑in printer quickly prints out all data and graphs.
• PC connection and software – Comes with an RS‑232 interface for connecting to a PC, plus Windows‑based circuit breaker data analysis software. Test data can be saved directly to your PC hard drive and printed using dot‑matrix, laser, or inkjet printers. This gives you computerized on‑site testing.
• Flexible speed analysis – Built‑in analysis software follows international standards for defining instantaneous closing/opening speed. It supports flexible data analysis and speed measurement for all switch models from any global manufacturer.
