Huazheng HZ2161 High Voltage Switch Circuit Comprehensive Tester

The design team of the high voltage switch circuit comprehensive tester has many years of field experience and a deep understanding of the actual working conditions. Through careful hardware design and software optimization, they have developed a targeted solution. While retaining the capability to perform individual tests, the system introduces an innovative intelligent testing mode. This mode not only meets the testing needs on-site but also significantly simplifies wiring and operation. Additionally, it features real-time voice prompts and wireless control of intelligent devices, making the testing process more streamlined, convenient, and efficient.

I. Performance Characteristics

It is suitable for the mainstream models of high-voltage circuit breakers both domestically and internationally and is equipped with a linear travel sensor and an incremental rotation sensor. The installation of the incremental rotation sensor can be done in any direction using a special plum connector, making the installation simpler and more stable.

◆ A special navigation plug interface is provided for the 10kV high-voltage circuit breaker, enabling fast, safe, and reliable connections for closing and breaking, as well as energy storage coil wiring. This eliminates safety hazards associated with wiring.

◆ The device features a 7-inch resistive color touch screen with a full Chinese menu display, real voice broadcast, and support for wireless connection control of intelligent devices. It can generate Word-format test reports, and data storage and printing are convenient.

◆ The test items include mechanical characteristics testing of the circuit breaker, breaking and closing coil resistance testing, circuit resistance testing, low voltage action voltage testing, and energy storage motor energy storage testing. Test items can be freely selected, and the instrument intelligently sorts the results, eliminating repeated invalid measurements.

◆ The instrument supports the storage of up to 999 sets of test data, and test parameters are not lost in the event of a power failure. The mechanical characteristics test can generate time-displacement diagrams and dynamic current schematics, while speed data can be re-measured and analyzed. It also provides a USB storage interface for convenient data storage.

◆ A USB communication interface is available for secondary programming control.
