Scope of Application
TXSPD Surge Protection Device is used for power supply systems of AC 50/60Hz, rated voltage 380V and below, to protect the power grid caused by lightning or surge overvoltage. The design is based on the IEC61643-1,GB18802-2002, it can discharge the 100kA lightning current, case is installed on 35mm electric rail, the detachment device automatically will be out of its power grid, meanwhile the status indicator turns from green to red. TXSPD Surge Protection Device has protection modes of common mode (MC) and differential mode (MD).TXSPD Surge Protection Device complies with the requirements of GB18802.1 and IEC61643-1 standard.
Structure and working principle
TXSPD Surge Protection Device in three-phase four-wire system, the surge protective devices are connected between the three phase lines and a zero line ground wire. Surge protective device is in high resistance state under normal circumstances, when surge voltage of the power grid caused by lightning or other causes appears , the surge protective device will immediately conduct in the nanosecond time to take surge into the earth, and to protect electrical equipment on the power grid. When the surge voltage passes through the protector, after disappears, the surge protective device changes to high resistance state, thereby not affecting the normal operation of the power network.
