هند بوک حفاظت در مقابل رعد و برق شرکت اریکو مطابق با استاندارد IEC 62305
طراحی حفاظت الکترومغناطیسی برای مراکز داده مطابق با استانداردهای محافظت رعدوبرق بین المللی به همراه اصول نصب ارستر و محافظ خطوط SPD در این سند بیان شده است.
رعد و برق همانند یک تهدید الکترومغناطیسی یک طیف فرکانسی و دامنه دارد ولی نسبت به یک تهدید الکترومغناطیسی طیف فرکانسی کمتری دارد.
رعدو برق به صورت مستقیم با برخورد صاعقه به خطوط هادی و فلزات در تاسیسات وارد می شود و خسارت وارد می کند.
تهدید الکترومغناطیسی به صورت امواج منتشر شده از منافذ هم وارد می شود و سپس در فلزات و خطوط هادی موجود القاء می شود همانند سازگاری الکترومغناطیسی از مسیرهای بیشتری قابلیت القاء داردو توانایی تخریب بیشتری دارد.

Introduction
This handbook is written to assist in the understanding of the IEC 62305 series of lightning protection standards. This guide
simplifies and summarizes the key points of the standards for typical structures, and as such, the full standards should be
referred to for final verification. This handbook does not document all IEC requirements, especially those applicable to less
common or high risk structures such as those with thatched roofs or containing explosive materials. In many situations there
are multiple methods available to achieve the same end result; this document offers Pentair’s interpretation of the standards
and our recommended approach. In order to provide practical advice, information is included on industry accepted practices
and from other standards.
The International Electrotechnical Commission (IEC) is a body responsible for implementing international standards. Its technical committees are comprised of representatives from various member national standards, where each country is entitled to one vote during the process of creation and issuing the standard. The standards generally have an IEC prefix to their number (CEI for French versions). IEC standards are produced in English and French languages. For most countries the adoption of these standards is voluntary, and often selected content of the standard is absorbed and introduced as improvements to that country’s own standard.
For the EN IEC 62305 series of lightning protection standards, each member country has introduced these at a national level by
November 2006 and has withdrawn any conflicting standards by February 2009.At each level (International, European, National) different naming prefix convention is used For example:
• IEC 62305-1 (IEC version)
• EN 62305-1 (CENELEC adopted copy of the above)
• BS EN 62305-1
This document focuses upon the IEC/EN standards and, for a specific design, the applicable national standards should be
referred to in order to ascertain if differences exist. Reference in this document is given to standards being either design or component standards. Design standards are those used by the lightning protection designer or installer to determine the type and placement of the lightning protection system.
Component standards are those used by the manufacturer of the lightning protection hardware (components) to ensure the hardware is of adequate specification and quality.
1.1. IEC 62305 series
The IEC 62305 series of standards are primarily design standards, giving the user a tool kit of rules and options to provide lightning protection for a structure. The standards cover structure protection and equipment protection with regard to the effects of direct and indirect lightning flashes.
While the IEC 62305 series of standards introduces many new
aspects, it is predominantly a European harmonization of the
various supporting country lightning protection standards.
“IEC 62305 Protection Against Lightning” is comprised of 4 parts
(documents):
• IEC 62305-1 Part 1: General Principles
• IEC 62305-2 Part 2: Risk Management
• IEC 62305-3 Part 3: Physical Damage to Structure and Life Hazard
• IEC 62305-4 Part 4: Electrical and Electronic Systems within Structures
• IEC 62305-5 Part 5: Services (This part was not introduced)
