Scope
Main technical content: This document specifies the maintenance classification and cycle, maintenance conditions, maintenance items and content, maintenance process requirements, testing, and post-maintenance effect evaluation for the spray-coating maintenance of high-voltage disconnect switches and contact surfaces of current-carrying circuits with nano-conductive agents. This document applies to the spray-coating maintenance of high-voltage disconnect switches and contact surfaces of current-carrying circuits with nano-conductive agents (specific technical parameters are shown in Appendix A) at voltage levels of 10 kV and above, including but not limited to high-voltage disconnect switch contacts, contact fingers, connection parts of conductive arms, equipment wiring boards, wire clamps, and other equipment (components) that have overheated during operation or had excessive circuit resistance during testing; this document is applicable when high-voltage disconnect switches undergo routine maintenance; the spray-coating maintenance of contact surfaces of current-carrying circuits of other equipment (such as mobile circuit breakers, open circuit breakers, ring main units circuit breakers, ring main unit disconnect switches, current-carrying busbars, etc.) can refer to this document.
