Working principle of high-voltage switch characteristic tester

The high-voltage switch characteristic tester is a specialized instrument used to test the mechanical dynamic characteristics of high-voltage circuit breakers. It is based on a high-performance industrial embedded platform, with high-speed data acquisition, analysis and processing capabilities, and can resist interference from strong electromagnetic fields (above 500KV). This tester can not only analyze the dynamic characteristics of multiple high-voltage switches simultaneously, but also has high testing accuracy.

The high-voltage switch characteristic tester has rich user-defined functions for different testing requirements of different switches. The instrument is equipped with an isolated adjustable DC power supply and a switch operation command simulation control module, so during testing, the opening, closing, and reclosing operations of the switch can be directly controlled through the attached DC power supply.

The working principle of the high-voltage switch characteristic tester is mainly based on the principle of electromagnetic induction and high-speed data acquisition, processing, and analysis technology.

After adding an AC power supply to the high-voltage switch, the tester indirectly measures the current flowing through the coil by measuring the change in the alternating magnetic flux generated by the coil. During the testing process, the measured current forms different magnetic field distribution states in the magnetic field, thereby generating induced electromotive force. According to the principle of electromagnetic induction, the leakage electricity through the coil can be calculated.

The core part of the tester includes modules such as signal generator, power amplifier, data processing, and display output. The signal generator generates a pulse signal, which is amplified by a power amplifier and drives the power amplification module to generate a power signal. The data collection system is responsible for completing the data collection work, which will then be processed and analyzed at high speed.

In addition, the high-voltage switch characteristic tester also has strong anti-interference ability, which ensures the accuracy and reliability of data in strong electromagnetic interference environments. During the testing process, the tester can record the opening and closing current, time, contact resistance and other parameters of the switch, and display them to the user in the form of graphics and data tables for comprehensive evaluation of the switch performance.

In summary, the high-voltage switch characteristic tester achieves precise testing and evaluation of the mechanical characteristics of high-voltage switches through the comprehensive application of electromagnetic induction principles, high-speed data acquisition and processing analysis technology.

ZC-300B circuit breaker analyzer can be used to test and measure the mechanical characteristic parameters of high voltage switch ( such as vacuum, six fluoride, less oil, oil and other power systems. The measurement data is stable, strong anti-interference ability, can be in the 500KV level and below the power station to do experiments, wiring is convenient, simple operation, is the most convenient tool for high-voltage switch maintenance test.
