Product Description

Product Description

       
        Transformer GIS SF6 switch CT/PT insulator bus bar cable bushing and others capacitive devices are the common primary electric equipments.

        The complete set of frequency conversion series resonance test equipment is mainly used for ac withstand voltage test of cross-linked cable, hydraulic generator, main transformer, bus GIS etc. 

       The complete set of frequency conversion series resonance test equipment is mainly composed of frequency conversion control power, supply excitation ,transformer reactor ,capacitor voltage divider and compensation capacitor (optional).





Product Characteristics

  • 1,The device has protection functions such as overvoltage overcurrent zero start system detuning (flashover) overvoltage and overcurrent protection values can be set according to user needs and flashover protection action when the sample flashes to protect the product.

  • 2,The entire unit is lightweight and easy to use on site.

  • 3,The device has three working modes which is convenient for the user to flexibly select according to the site conditions and improve the test speed. The working modes are: fully automatic mode manual mode and automatic tuning manual boost mode.

  • 4,It can store and print data off-site and the stored data number is a number which is convenient for users to identify and find.

  • 5,When the device is automatically swept the starting point of the frequency can be arbitrarily set within the specified range and the large screen of the liquid crystal displays the scanning curve which is convenient for the user to intuitively know whether to find the resonance point.

  • 6,The DSP platform technology is adopted which can conveniently increase or decrease functions and upgrades according to user needs and also makes the human-machine exchange interface more humanized.
