The device is mainly designed and manufactured for AC withstand voltage test of all electrical main equipment such as power main transformers and busbar switches of 35kV and below. The reactor adopts a multiple separate design, which can meet the test conditions of high voltage and low current equipment, and can also meet the AC withstand voltage test requirements of low voltage such as 10kV cables. It has a wide range of applications and is an ideal withstand voltage equipment for high voltage test departments at prefecture, city and county levels and power installation and repair engineering units.
1. The device has protection functions such as overvoltage, overcurrent, zero-position start, system detuning (flashover), etc. The overvoltage and overcurrent protection values can be set according to user needs. When the test product flashes, the flash protection will be activated and the flashover voltage value can be recorded for test analysis.
2. The weight of the entire device is very light, with a maximum weight of no more than 40kg, which is convenient for on-site use.
3. The device has three working modes, which is convenient for users to flexibly choose according to on-site conditions and improve the test speed.
4. The working modes are: full automatic mode, manual mode, automatic tuning manual boost mode,
5. It can store, and the stored data number is a number, which is convenient for users to identify and find.
6. When the device automatically sweeps the frequency, the frequency starting point can be set arbitrarily within the specified range, and the sweep direction can be selected up or down. At the same time, the large LCD screen displays the scanning curve, which is convenient for users to intuitively understand whether the resonance point is found.
7. The DSP platform technology is adopted, which can easily increase or decrease functions and upgrade according to user needs, and also makes the human-computer exchange interface more humane.
