Abstract:
The present invention relates to a new discharge element having a discharge-control electrode for inducing a discharge even at low voltage by improving a characteristic in which a discharge element may not be discharged against a fast transient voltage when it is at low voltage, and more specifically, the discharge element having a discharge-control electrode according to the present invention comprises an airtight cylinder formed with a ceramic insulation material, a pair of discharge electrodes arranged for facing an end opening of the airtight cylinder, a discharge gap formed between the pair of discharge electrodes, a discharge-assisting material filled inside the airtight cylinder, and a discharge-control electrode in contact with the airtight cylinder and physically separated from the discharge-assisting material, wherein a discharge between the pair of discharge electrodes is induced by a control voltage applied through the discharge-control electrode.
Abstract:
The present invention relates to a smart bonding method. In the smart bonding method for equipment in which a power source and a communication line are connected to each other, a surge protector for the power source is connected to the power source line, and a surge protector for communication is connected to the communication line. Also, the ground terminals of the surge protector for the power source and of the surge protector for communication are connected to each other to form a common ground terminal. Here, the common ground terminal is connected to the conductive frame of the equipment. As described above, the potential difference between all lines of the equipment is equal to the potential of the ground through the surge protectors. Thus, a surge current may be interrupted to fundamentally prevent damage due to a lightning surge from occurring.
