西安咸阳国际机场微秒级“电力卫士”上岗

Core Viewpoint - The modernization of Xi'an Xianyang International Airport is advancing, necessitating continuous technological upgrades to ensure a reliable power supply system for smooth airport operations [1][2]. Group 1: Airport Modernization - The commissioning of the T5 terminal and supporting facilities is likened to injecting a strong "heart" into the airport, presenting unprecedented challenges to the airport's power supply system [1]. - The expansion of the distribution network and the long-distance cable laying are critical tasks to build a power supply guarantee system focused on high reliability, intelligence, and multi-dimensional safety [1]. Group 2: Technological Innovations - The introduction of an intelligent fault management system with microsecond-level arc suppression technology aims to address grounding fault arcs, a significant risk in the power supply system [2]. - This advanced system utilizes multi-modal fault diagnosis algorithms and rapid phase grounding switch modules, capable of detecting and extinguishing arcs within 20 milliseconds during single-phase grounding faults [2]. - The system has significantly improved response efficiency compared to traditional protection systems, effectively preventing the escalation of faults and reducing downtime for lower-level electrical equipment at the airport [2]. Group 3: Operational Efficiency - The implementation of this system has not only reduced the risk of prolonged arc burning but also saved substantial time for maintenance personnel by automating fault handling reports, enhancing safety and operational efficiency in complex power grid environments [2].
