Scope

This document defines the terms and definitions of dry-air insulated vacuum circuit-breaker type AC metal-enclosed switchgear (hereinafter referred to as switchgear) with a rated voltage of 72.5 kV for wind power boosting systems in marine environments. It specifies the conditions of use, rated values, design and structure, type testing, factory testing, guidelines for selecting switchgear and control equipment, information provided in inquiries, bids, and orders, transportation, storage, installation, operation and maintenance, safety, and the product's impact on the environment.
This document applies to the design and manufacture of dry-air insulated vacuum circuit-breaker type AC metal-enclosed switchgear with a rated voltage of 72.5 kV for wind power boosting systems in marine environments.
Note: For special devices and equipment in switchgear, in addition to meeting the requirements of this document, they must also comply with relevant product standards. When used in other environments, the switchgear manufacturer needs to consult with the user to determine the specific requirements.
