Fully Gas Insulated Modular and Compact (RMU) System Up to 24 kV
Themodular and compact switchgear is composed of a set of reduced sizemodular cubicles, single or multifunctional, for different Medium Voltagesecondarypowerdistributionconfigurationsupto24kVinpublicandindustrialsettings.
Boththebreakingandswitchingcomponentsaswellasthebusbararelocatedinside a stainless steel SF6-filled gas tank which is permanently sealed,thus building a fully insulated unit. This provides protection against harshenvironmentalelements(includingflooding),longservicelifeandmaintenance-freeofliveparts.
Main Features
• Fullmodularity, connectivity and future extendibility in bothsidesusingtheconnectingset.
IEC60298Metal-enclosed switchgear for alternating current ratedvoltagesover1kVandunder52kV.The system has been designed and tested towithstand aninternalarcinaccordancewithAppendixAA.
IEC60265High voltage switches - Part 1 : High voltage switches forratedvoltagesover1kVandunder52kV.
This assembly connects the main busbar of the extendiblecubicles, allowing current to flow while also controlling theelectricfield.
Other important aspects are the capacity to maintain thesamefunctionalcharacteristicsofthecubiclesandtheeaseofinstallation,evenintransformersubstationswithunevenfloors.
Overview
IEC60694Common specifications for high-voltage switchgear andcontrolgearstandards.
The system has a series of interlocks to ensure safe, reliableservice, inaccordancewith the requirementsof the IEC60298standard. Based on the design and the inclusion of additionalinterlocks, the switch-disconnector and the earthing switchcannotbeclosedsimultaneously.
The design is according to IEC 61958 standard, indicates thepresenceofvoltageinthephasesofeachfunction.
