Surge protection unit for railway applications XLY-380/40-Q

for power suppliesmodularthree-phase

XLY-380/40-Q dual-circuit parallel power lightning protection box, equippedWith high-performance module components and high-quality circuit breakers, iscarefully designed and professionally manufactured. lt is widely applied to thepower box of the railway communication machinery room to realize thecomprehensive protection of the three-phase power supply system: differentialmode (lateral) protection for LI-N, L2-N, L3-N; common mode (longitudinal)protection for LI-PE, L2-PE, L3-PE and N-PE. lt realizes protection againstlightning induced overvoltage and surge overcurrent. ● The inside of the box adopts high-performance modular components, good non-linearity, large flow, low residual pressure, excellent quality. The module has a built-in dynamic thermal trip device, which will act immediately after deterioration, so that the lightning protector can be safely removed from the main circuit. ● 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. ● The board has a lightning counter, which can record the number of lightning strikes, and has a reset button. 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. With remote signal alarm terminal, it is convenient for remote monitoring and can realize unattended operation.
