NB/T 11307.4-2024 Risk Assessment Guidelines for Fire Hazard of Electric Power Equipment and Materials - Part 4: Parallel Reactive Converter Resonator
Basic Information
Scope
This document specifies the materials used for converter valve parallel reactors (anode saturation reactors) and the fire hazard test methods for the entire parallel reactor, as well as the fire hazard rating assessment and requirements for the materials used in parallel reactors and the entire reactor. This document applies to the fire hazard test methods, fire hazard rating assessment, and rating requirements for materials such as converter valve parallel reactors, their conductor insulation, epoxy resin reinforcement strips, and epoxy fiberglass encapsulation (RTV) used in (ultra) high-voltage direct current projects. The test methods described in this document include standard-sized samples, which are only used to measure and assess the ignition performance and fire hazard rating of insulating materials used in converter valve parallel reactor equipment components under controlled laboratory conditions against specified heat sources and flames.
