Recently, Wuhan Jindian Technology successfully delivered a set of NR-BX-2200kVA/400kV variable frequency resonance test device to Jiangsu Fangyang Energy Technology Co., Ltd., the winning bidder.

    product description  

    The NR-BX-2200kVA/400kV variable frequency resonance test device is mainly designed and manufactured for the AC withstand voltage test of 110kV, 220kV cables and power transformers, and all electrical main equipment of the 220kV power system. The reactor adopts multiple separate designs, which can meet the requirements of high voltage and small current equipment test conditions. It is an ideal withstand voltage equipment for high-voltage test departments at prefecture, city and county levels, as well as power installation and repair and test engineering units. It is mainly composed of variable frequency control power supply, excitation transformer, high voltage reactor, and capacitive voltage divider. The whole device is light in weight and small in size, which is convenient for field test.

    · The device has protection functions such as over-voltage, over-current, zero start, system detuning, high-voltage flashover failure, etc. The over-voltage and over-current protection value can be set according to user needs, and the flashover protection action can be recorded during the flashover of the test product. The value of flashing voltage for test analysis;

    · It has two working modes: full automatic mode and manual mode, which is convenient for users to choose flexibly according to the on-site situation and improve the test speed;

    · During automatic frequency sweep, the starting frequency can be set arbitrarily within the specified range, and the sweep direction can be selected upwards and downwards. At the same time, the large color LCD screen displays the scanning resonance, boost, and timing curves to facilitate the user to intuitively understand whether the resonance point is found .

    · It can store timely printing and remote printing data. The stored data number is a number, which is convenient for users to identify and find.

    · Adopting DSP platform technology, you can easily add or remove functions and upgrades according to user needs, and also make the man-machine exchange interface more user-friendly.
