Catégorie : Protection contre les surtensions et la foudre

Lorsque la foudre frappe à moins d'un kilomètre de votre installation solaire ou de votre station de recharge pour VE, la surtension qui en résulte peut se propager dans votre système électrique en quelques microsecondes, détruisant des onduleurs valant des milliers de dollars, grillant les régulateurs de charge et rendant inutilisables les coûteux parcs de batteries.....

Résumé En tant que responsable des achats développant des produits électriques pour les nouvelles énergies, le partenariat avec le bon fabricant OEM/ODM est essentiel à la réussite de votre projet. CNKUANGYA Electrical Equipment Supply apporte 25 ans d'expertise dans la protection photovoltaïque DC, les systèmes d'isolation AC et...

As energy storage systems (ESS) become increasingly critical to renewable energy infrastructure, protecting these valuable assets from voltage surges and lightning strikes has never been more important. DC Surge Protection Devices (DC SPDs) serve as the first line of defense,…

Introduction ESS today’s rapidly evolving solar-plus-storage landscape, the risk of single-point failures bringing down entire power plants has become increasingly prominent. According to recent industry data, over 80% of PV-ESS system failures stem from inadequate protection coordination, with the vast…

By CNKuangya Senior Engineer Executive Summary SPD: electrical systems become increasingly sophisticated and vulnerable to transient over voltages, the implementation of IEC 61643-31 compliant Surge Protective Devices (SPDs) has evolved from a recommended practice to an essential requirement. This comprehensive…

dc spd: Solar energy systems represent a significant financial investment, often requiring decades to deliver full returns. Yet many system owners overlook a critical component that can mean the difference between long-term profitability and catastrophic failure: the DC surge protection…

DC SPD： the global transition to clean energy accelerates, electric vehicle (EV) charging networks and battery energy storage systems (BESS) have become two of the most critical pillars of modern power infrastructure. Billions of dollars are being invested in charging…

Une liste de contrôle pratique pour qualifier un fabricant de parafoudres CC pour installations photovoltaïques : confirmer le champ d'application de la norme IEC 61643-31, les caractéristiques nominales spécifiques au modèle, les preuves d'essais, la traçabilité et les instructions d'installation.

A DC surge protective device (SPD) limits transient overvoltage and diverts surge current away from equipment. For solar PV, the key questions are where the device is installed, whether it is rated for the maximum PV open-circuit voltage at the…

Looking for an SPD manufacturer in China? Start with verifiable product documentation—not a “best manufacturer” claim. This guide presents five China-based suppliers with identifiable surge-protection product ranges and explains how to verify certificates, test reports, model scope, factory capability, and…
