DL-LX26AL series of zero sequence current transformer residual current detection, electrical fire monitoring
The function and working principle of zero sequence current (residual current / leakage current) transformer: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- Two abnormal phenomena occur when the electrical equipment leakage: First, the balance of the three-phase current is destroyed, there is zero sequence current; The two is that when the normal non charged metal casing appears on the ground voltage (normal, the metal shell and the earth are zero
DL-LX45AL series of zero sequence current transformer residual current detection, electrical fire monitoring
The zero sequence current transformer is the leakage protection device through the zero sequence current transformer detection to obtain abnormal signals, through the intermediate mechanism to transfer, so that the implementation of the action, through the switch device to disconnect the power supply. Similar structure and transformer of current transformer (CT) is composed of two mutually insulated winding coils on the same core composition. When the residual current of a
