| High Voltage Switch Simulation Characteristic Tester |
Product Application Scope and Features:
Can test the mechanical characteristic parameters (time, synchronization, bounce, travel, speed, operating voltage, current, rebound, coordination time between main contacts and auxiliary switches, mechanical operation and other data and waveforms) of various domestic (imported) vacuum, SF6, oil high-voltage circuit breakers, load switches, GIS grounding disconnectors, contactors, relays, air switches and other switches. Precise analysis and calculation functions allow flexible definition of switch speed. Large capacity data storage directly on hard disk, with data import and export for easy viewing and printing. The instrument has a built-in adjustable DC power supply for closing, opening, and reclosing tests, as well as low voltage operation tests.
Product Overview:
Switch Mechanical Characteristic Tester is a new generation tester developed based on DL/T 846.1~DL/T 846.9 — 2004 "High Voltage Switch Comprehensive Tester", DL/T596-1996 "Electric Power Preventive Test Procedure", GB/T1984-2003 "High Voltage AC Circuit Breaker". It can test the mechanical characteristic parameters (time, synchronization, bounce, travel, speed, operating voltage, current, rebound, coordination time between main contacts and auxiliary switches, mechanical operation and other data and waveforms) of various domestic (imported) vacuum, SF6, oil high-voltage circuit breakers, load switches, GIS grounding disconnectors, contactors, relays, air switches and other switches. Precise analysis and calculation functions allow flexible definition of switch speed. Large capacity data storage directly on hard disk, with data import and export for easy viewing and printing. The instrument has a built-in adjustable DC power supply for closing, opening, and reclosing tests, as well as low voltage operation tests. Panel-mounted wide high-speed thermal printer can print all data and action characteristic curves at any time. Windows operating system, touch screen operation, large screen color LCD display. Equipped with upper computer software for further data analysis, storage and various report printing. Widely used in power supply systems, switch manufacturers, industrial and mining enterprises, metallurgy, railways and other power-using departments for factory, handover, preventive and maintenance tests.
