Scope
This document specifies the normal and special operating conditions, rated values, and design and structural requirements for high-voltage AC disconnect switches and grounding switches, describes the corresponding type test and factory test methods, provides selection guidelines, and stipulates transportation, storage, installation, operation, and maintenance requirements.
This document is applicable to AC disconnect switches and grounding switches designed for indoor and outdoor installation and operation in systems with a frequency of 50 Hz or lower and a nominal voltage of 3 kV or higher.
This document is also applicable to the operating mechanisms and auxiliary equipment of these disconnect switches and grounding switches.
The additional requirements for disconnect switches and grounding switches in enclosed switchgear and control equipment are given in GB/T 3906—2020 and GB/T 7674-2020.
This document is also applicable to switching devices that, in addition to other functions, also have isolation and/or grounding functions, such as rapid grounding switches, circuit breakers, and load switches.
