TKBPXZ series resonance device series resonant frequency series resonant test device is the use of the principle, the use of excitation transformer series resonant excitation circuit, inverter controller to adjust the output frequency to the test circuit inductance L and C series resonance, resonant voltage that is applied to the test voltage. Resonant frequency test equipment is widely used in electric power, metallurgy, petroleum, chemical industry, for large capacity, high voltage capacitive transfer test and preventive tests. TKBPXZ series resonant frequency voltage device consists of a controller, excitation transformers, high-voltage reactors, high voltage divider and other components. Inverter controller is divided into two categories, 20KW and above the control desk, 20KW following portable box; it by the controller and filter. Frequency controller main role is to amplitude and frequency are constant 380V or 200V AC power into frequency sinusoidal amplitude and frequency adjustable sine wave. And provide power for the entire device. The role of the excitation frequency power transformer is the output voltage rises to the appropriate test voltage. Reactors L is an important component of the resonant circuit, when the power supply frequency is equal to 1 / (2π√LCX), it happened with the test CX series resonance. Series resonant frequency test equipment suitable for 10KV, 35KV, 110KV, 220KV, 500KV power cables polyhexene AC voltage test. Suitable for 60KV, 220KV, 500KVGIS AC voltage test. For large transformers, generators frequency voltage withstand test; power transformer sensing pressure test; earth resistance measurement. Products nickname series resonant series resonant transformer resonant frequency, series resonant frequency, series resonance test equipment, series resonance principle, the series resonant series resonant system application http://www.whgdmk.com/aspcms/product/2014-4-29 Features a /50.html, stability, and high reliability. Imported power system components as the core power conversion, voltage output and frequency output stability, reasonable EMC design, the protection function, after several high-voltage direct ground short of the test, the system remains intact, and the system also has a strong overload 2 capability, auto-tuning and powerful. When the system automatically tune from 30Hz to 300Hz automatically sweep, sweep curve display, the user can visually see the system tuning process; after the sweep is complete, the system according to the resonant frequency sweep initially found in its range within ± 5Hz with fine frequency resolution 0.01Hz to sweep, finally pinpoint the resonant frequency of the three, supports multiple test modes. The system supports "auto-tuning + manual regulator", "auto-tuning + automatic voltage regulator", "Manual tuning + manual regulator" and a test mode, we recommend using the "auto-tuning regulator + manual" mode, both quickly find resonance point , but also by manual voltage control testing process, higher security 4, the system user-friendly human-computer interaction. Test parameters, test control, test results equivalent screen display, intuitive and clear, and has automatic timing and operation prompts. Full touch screen operation and display, with test data storage and query capabilities 5, the protection function. Have zero protection (voltage output control knob is not zero, disable the system start), overvoltage protection, overcurrent protection, flashover protection and other functions, to ensure the reliability of the system http://www.whgdmk.com
