Single-phase surge protection unit TD-220/ZN

common modeN-PEbuilt-in

TD-220/ZN dual-circuit parallel intelligent power lightning protection box, equipped with high-performance module components and high-quality circuit breakers, is carefully designed and professionally manufactured. It is widely used in the power box of railway communication machinery room to realize comprehensive protection of single-phase power supply system: differential mode (lateral) protection between L-N lines; common mode (longitudinal) protection of L-PE and N-PE. It realizes protection against lightning induced overvoltage and surge overcurrent. In addition, it has built-in data acquisition terminal of the intelligent lightning protection system, which can monitor the lightning strike information (lightning current amplitude, lightning current polarity, strike time, number of lightning strikes) and SPD status in real time and accurately. The processor uses the communication interface RS485 or Ethernet to transmit the monitored data to the upper computer, so that the user can get the information in time, so as to implement maintenance quickly. ● Optimized circuit design, comprehensive protection in vertical and horizontal directions. ● High-quality circuit breakers are adopted; stable and reliable operation. ● The lightning protection module can be plugged and replaced when powered, which is convenient for maintenance and has no impact on the circuit operation.
