Tuning Resonance Test Device
Brief introduction
BPXZ series tuning resonance test device is designed special for AC withstand test of 11kv\30mw water turbine generator. The reactor is designed for seperate two. This device is composed of contolling power supply, exciting transformer, reactor and capacity voltage divider.
Product features
◆The device has protection function of overvoltage, overcurrent, zero start-up, system detuning(flashover), overvoltage and overcurrent protection value can be set to act when the tested product flashover according to user’s requirement. It can record the flashover voltage value for test analysis.
◆The weight of the device is light and not more than 40kg, easy to use on site.
◆There are four working modes. Convenient for user choosing on site and impove the working speed. Working modes: auto mode, manual mode, auto tuning mode, manual boosting mode.
◆Can save and remote print the data, the saved data serie number is digital data, convenient for user to identify and find.
◆When the device automatically sweep starting frequency can be set within a predetermined range. Sweep direction can be chosen from up or down. At the same time the sweeping wave display on LCD, convenient for user to know intuitively whether it find the resonant point.
◆Use DSP technology, can increase and reduce functions and upgrade according to user’s need making the man-machine interface is more humane.
