Deskripsyon

±500~±1100kV DC Metal Oxide Surge Arresters kay mga kritikal nga mga pananglitan nga gihimo alang sa high-voltage direct current (HVDC) transmission systems nga nagoperasyon sa ±500kV hangtod sa ±1100kV range. Kini nga mga arresters gitipon ang advanced metal oxide varistors (MOVs) sa robust nga mga balay (kadaghanan composite o porcelain) aron mapahimulos ang transient overvoltages sa DC grids—tulad sa mga resulta sa lightning strikes, converter station switching operations, o system faults. Gisulod sila sa HVDC converter stations, transmission lines, ug uban sa key equipment sama sa valves ug transformers, aron mapalitli ang excessive surge currents sa yuta habang nagsuporta sa voltage levels sa safe thresholds. Sa pagmitig sa overvoltage risks, sila nagprotekta sa integridad sa HVDC infrastructure, nagaseguro sa stable power transmission tali sa grids, ug nagreduce sa downtime gikan sa equipment damage.

Mga Katangian

  • HVDC Voltage Range Optimization:Tailored for ±500kV to ±1100kV DC systems, with rated parameters precisely matched to the unique demands of high-voltage direct current grids. Designed to handle unidirectional current characteristics and sustained DC stress, ensuring reliable performance in long-distance HVDC transmission networks.

  • Robust Housing & Environmental Resistance
    Housings (composite silicone rubber or high-strength porcelain) offer superior durability: resistance to UV radiation, extreme temperatures, and pollution ensures suitability for harsh outdoor environments (e.g., deserts, high-altitude regions). Composite options add lightweight design and hydrophobicity to reduce flashover risks.

  • Handling Polarity & Transient Stresses:Engineered to withstand polarity reversals and DC-specific transients (e.g., converter-generated overvoltages). Unlike AC arresters, they maintain stability under sustained unidirectional voltage, critical for protecting HVDC valves and converter transformers from long-duration overvoltage exposure.

  • High Energy Absorption Capacity:Capable of absorbing large amounts of surge energy from severe events (e.g., direct lightning on DC lines or converter faults). This high energy handling ensures they can mitigate even extreme overvoltages without degradation, enhancing HVDC system resilience.

  • Low Maintenance & Long Lifespan:Stable MOV performance under DC stress reduces drift in leakage current, minimizing maintenance needs. Housings resist aging and corrosion, while robust internal components extend service life to 20+ years, aligning with the long operational cycles of HVDC projects.

  • Compliance with Global Standards:Meets international standards for HVDC arresters (e.g., IEC 60099-8, IEEE C62.34), ensuring compatibility with global HVDC systems. Rigorously tested for DC voltage endurance, impulse current withstand, and thermal stability to guarantee safe operation in critical infrastructure.

  • Integration with HVDC Control Systems:Many models support integration with HVDC monitoring systems, featuring sensors to track leakage current and temperature. This enables real-time performance monitoring, facilitating predictive maintenance and early fault detection in large-scale DC grids.
