Scope

This document specifies the technical requirements, test methods, inspection rules, and marking, packaging, and storage for pressure-type SF6/N2 mixed gas density relays. This document applies to SF6/N2 mixed gases with a sulfur hexafluoride volume accounting for (30±2)% of the total volume, and uses spring tubes or bellows as measuring elements. It also includes a temperature compensation device and a pressure-type SF6/N2 mixed gas density relay with functions of indicating and controlling the on/off of electrical signals.
