Description
Variable Inductance Resonance Test Set HYXZ-800KV/6000KVA is mainly for the AC withstand voltage test of cross-linked cable, hydraulic generator, main transformer, busbar, GIS, etc. It has a wide range of application and is the ideal withstand voltage equipment for local, municipal and county high-voltage test departments and electric power installation and repair test engineering units.
The device is mainly composed of frequency control power supply, excitation transformer, reactor, capacitor divider and compensation capacitor (optional).
Features
1.The device has over-voltage, over-current, zero-start, system detuning (flashover) and other protection functions, over-voltage and over-current protection values can be adjusted according to user needs, flashover protection action when the test product flashover, to protect the type product.
2.The entire unit is light in weight as a single piece, making it easy to use in the field.
3.The device has three working modes, which is convenient for users to choose flexibly according to the site situation and improve the test speed.
The working modes are: fully automatic mode, manual mode, and auto-tuning manual boost mode.
4.Capable of storing and printing data offsite, the deposited data numbers are numeric, which conveniently help users identify and find them.
5.Automatic frequency sweeping device frequency starting point can be set within the specified range arbitrarily, while the LCD large screen display scanning curve, convenient for users to intuitively understand whether to find the resonance point.
6.With the DSP platform technology, it is easy to add or subtract functions and upgrade according to user needs, which also makes the human-machine exchange interface more user-friendly.
