TD-220/ZN Intelligent Power Lightning Protection Box

Product Application

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.  

Product features

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. 
With sound-light alarm function, it can realize the alarm of power supply lack of phase, open circuit of circuit breaker, aging and tripping of lightning protection module, and the display is clear and timely. At the same time, it has the data collection terminal of the communication intelligent lightning protection system, which can collect the lightning protection data in the communication cable intelligent surge protector through the bus, and upload it to the railway communication transmission network through the RS485 interface or the Ethernet interface. It is convenient for remote monitoring, which can realize unattended operation. 
It can collect one circuit lightning current data, including lightning strike times, magnitude detection, detection range 1-100KA, error ±10%.  
LCD display is used to facilitate users to check the operating status, current alarms and historical records. 
 Follow RS485 half-duplex MODBUS RTU mode protocol communication; with simple networking, it’s convenient for centralized monitoring. 
The upper and lower parts of the box have holes and special wiring terminals are used. The power cable is easy to enter and exit, and the connection is reliable. 
The sound-light alarm can be powered by rechargeable batteries and mains electricity, and the operation is stable and reliable. 
 The main technical characteristics of the surge protector: see product specification for details.
