In power systems and industrial equipment, the performance of high-voltage circuit breakers is directly related to the stability and safety of the power grid. In order to meet the industry's demand for high efficiency and accuracy in circuit breaker testing, the GKC-HAJ-MH AC/DC switch characteristics and running-in device test system came into being.

Product core advantages: accurate testing, intelligent and efficient

Multi-scenario adaptation, wide compatibility

◆ Supports a variety of high-voltage circuit breaker types such as SF6 switches, vacuum switches, oil switches, etc., covering mainstream brand equipment at home and abroad.

◆ Built-in AC/DC adjustable power supply (AC/DC 6~270V) meets the testing requirements of 24V/15A coils and adapts to circuit breakers of different voltage levels.

High-precision measurement, comprehensive data

◆ Time measurement: 12-way break signal synchronous acquisition, resolution up to 0.01ms, accurately capture the opening and closing time, bounce time and different periods.

◆ Speed and stroke: Equipped with linear, rotary and universal sensors, it supports real-time analysis of opening/closing speed, maximum speed and average speed of travel segment, with an error as low as ±0.1m/s.

◆ Current and resistance: The coil current measurement range is up to 30A, and the resistance measurement covers 0~2000Ω, with an accuracy of ±5%, ensuring the health status assessment of the equipment.

Intelligent running-in device, safe and reliable

◆ Multi-mode running-in: Supports preset modes such as single opening, single closing, closing opening, opening closing opening, etc., and can set 1~10000 running-in times, suitable for ordinary circuit breakers and contactors.

◆ Precise voltage control: Independent adjustment of opening and closing voltages (such as 85% closing voltage, 65% opening voltage) to avoid overheating and damage to the coil.

◆ Fault protection mechanism: Real-time monitoring of the break status, immediate alarm and shutdown in case of refusal to close/open, built-in insurance and power protection functions to eliminate short circuit risks.

Humanized operation, efficient and convenient

◆ 15-inch industrial-grade touch screen equipped with Windows system, intuitive interface, supports switching between Chinese and English.

◆ Data and waveform are displayed on the same screen, and Word reports are generated with one click to simplify the data analysis process.

◆ Breakpoint memory function: you can choose to continue or reset after an unexpected interruption to improve test efficiency.
