Hipot Testing
ASHPT Hipot Testing Device(frequency conversion series resonant withstand voltage test device), which uses the way of adjusting the power supply frequency, make the reactor and the capacitor to achieve resonance, so as to obtain high voltage and high current on the tested products. Because of its small power supply and small equipment weight, it has been widely praised and applied at home and abroad. It is a new method and trend of high voltage tests at present.
The device is mainly aimed at AC withstand voltage test of cross-linked cables, hydroelectric generators, main transformers, buses, GIS, etc. It has a wide range of applications. It is an ideal withstand voltage equipment for local, municipal, and county high voltage test departments and electric power installation and repair engineering units.
The hipot testing device is mainly composed of frequency conversion control power supply, excitation transformer, reactor, capacitor voltage divider, and compensation capacitor.
Features
1. The device has the protection functions of over-voltage, over-current, zero-position start, system detuning (flashover). The protection value of over-voltage and over-current can be set according to the user’s needs. The flashover protection action of the test product can be recorded when flashing, so as to provide test analysis.
2. The whole device is light in weight and easy to use on-site.
3. The device has three working modes: full-automatic mode, manual mode, and automatic tuning manual boost mode. It is convenient for users to choose flexibly according to the site conditions and improve the test speed.
4. It can store and print data in different places. The number of data stored is digital, which is convenient for users to identify and search.
5. The starting point of frequency can be set arbitrarily in the prescribed range when the device scans frequency automatically. The direction of frequency scanning can be selected up and down. At the same time, the scanning curve can be displayed on the large LCD screen, so that users can intuitively know whether to find the resonance point.
6. Using the technology of the DSP platform, the functions and upgrades can be added or subtracted according to users needs, and the man-machine interface is more humanized.
In addition to a high-voltage testing devices, Assen also provides various oil analysis instruments.
