Product Overview
The GKC-8000 Switch Characteristic Tester is a dedicated testing device for measuring the mechanical characteristics of high-voltage circuit breakers. The instrument adopts an industrial-grade microprocessor and high-speed data acquisition circuit, and can measure and analyze parameters such as opening/closing time, simultaneity, and travel curve of circuit breakers. It is suitable for on-site testing and laboratory calibration in power systems, industrial and mining enterprises, and maintenance units.
Main Functions
The instrument supports time parameter measurement for closing, opening, and reclosing operations, including inherent opening time, closing time, three-phase asynchronism time, bounce time, etc. It can also be connected to linear or rotary sensors to measure moving contact travel, overtravel, gap, and speed characteristics. With a built-in energy storage power supply, it supports on-site passive operation and features automatic identification of break signals, simplifying the wiring process.
Technical Parameters
Time measurement range: 0.1ms～10s, resolution 0.1ms, accuracy ±0.5% reading ±0.2ms. Travel measurement range: 0～1000mm (depending on sensor), resolution 0.1mm. Speed measurement range: 0～20m/s, accuracy ±1% reading. Break voltage: DC24V～DC270V adaptive. Power supply: AC220V±10% or built-in lithium battery. Operating temperature: -10℃～50℃. Storage capacity: can save 200 sets of test data, supports USB flash drive export.
Application Scenarios
The tester is suitable for substations, power plants, switch manufacturers, and power maintenance companies to conduct mechanical characteristic tests on high-voltage circuit breakers of types such as minimum oil, bulk oil, vacuum, and SF6. It can be used for handover acceptance of new equipment, periodic preventive testing, and post-fault operation characteristic diagnosis, helping operation and maintenance personnel evaluate the health status of circuit breaker operating mechanisms.
Instructions for Use
The instrument is equipped with a color LCD touch screen, a simple operation interface, and supports a Chinese menu. After testing is completed, it can automatically generate time-travel curves and data reports for on-site analysis. Please correctly connect the sensors and break wires according to the user manual to ensure reliable grounding. This product complies with relevant industry standards, and specific technical indicators are subject to the factory inspection report.
