Core functionality
Rapid time measurement (high-precision time parameter): capable of simultaneously measuring the opening and closing time, phase out of phase, and three-phase different periods of multiple circuit breakers. High precision measurement has been achieved, allowing any subtle time deviation to be exposed.
Comprehensive analysis of speed and stroke: The instrument can automatically calculate key physical indicators such as initial opening speed, initial closing speed, maximum speed, as well as opening distance, overtravel, and total stroke, to comprehensively evaluate the mechanical transmission efficiency of the switch.
Bounce time and frequency capture: Accurately record the contact bounce time and bounce frequency of the switch during the closing process. Bouncing is a hidden danger that can cause contact burnout and arc fluctuations, and high-precision capture can provide key technical basis for equipment maintenance.
Intelligent action voltage testing: The device is equipped with an adjustable operating power supply, which can automatically or manually perform low voltage action tests (low voltage closing, low voltage opening) on the circuit breaker to evaluate the reliability of the coil under extreme voltage conditions.
Application Scenarios
1. Power system maintenance
In the daily maintenance of the power system, the tester is used to regularly check the mechanical characteristics of high-voltage switches to ensure that the equipment is in good operating condition. It can measure parameters such as opening and closing time, speed, and stroke, and promptly detect switch performance degradation or potential faults, ensuring the safe and stable operation of the power grid.
2. Fault analysis
When the high-voltage switch malfunctions, the tester can quickly capture the mechanical characteristic data at the time of the fault, such as exceeding the limit of asynchronous opening and abnormal bounce times. By comparing normal data, analyzing the cause of faults, providing a basis for maintenance, and shortening the time for fault handling.

4. On site emergency response
In case of sudden malfunction or emergency repair, the tester can be quickly deployed to the site to perform real-time detection of high-voltage switches. Its portability and ease of operation make it an important tool for on-site emergency response, helping technicians quickly locate problems and restore power supply.
5. Training and teaching
Testers are used in practical teaching in electrical engineering training to enable students to intuitively understand the working principle and mechanical characteristics of high-voltage switches. Through practical operation, students can master the skills of switch detection and improve their ability to diagnose faults.
6. Quality inspection
In the production process of high-voltage switches, the tester is used for quality inspection before leaving the factory to ensure that the mechanical characteristics of each switch meet the standards. It can automatically generate detection reports, provide data support for quality traceability, and ensure product quality.
