High voltage rapid protection board

Instructions for using flashover protection device:

Led out from the signal board2Root wire, string between the high voltage arm and low voltage arm of the voltage divider (with a magnetic ring inside that will not affect impedance), useSTmultimode fiber The length is connected according to its own needs, and the acquisition board does not require a working power supply.

Control board: The control board is equipped with a transformer, which is connected to220VThe power supply should be connected to the control board, and the other terminals should be plugged into the power supply. When the ignition is turned on, the relay will activate and reset to accept it24VVoltage, relay reset. At the same time, there is a reset button for the reset relay on the control board, and there is also a potentiometer on the control board that adjusts the signal sensitivity.

Used for series resonance and power frequency testing on transformers, the voltage flashes instantaneously. The signal is transmitted through the acquisition box and optical fiber, so that the instantaneous response time of the backend relay is generally 10ms (this time is mainly the response time of the relay), thereby cutting open the primary side equipment circuit and providing a fast protection method. Usually used in high-voltage electrical, chemical, and automation control industries. Provides quick protection and facilitates safe operation of equipment. The power industry should be able to use it all.
