Definitions and NomenclatureHistory and ControversyHypervalent HydridesCriticismAlternative DefinitionBonding in Hypervalent MoleculesStructure, Reactivity, and KineticsHypervalent molecules were first formally defined by Jeremy I. Musher in 1969 as molecules having central atoms of group 15–18 in any valence other than the lowest (i.e. 3, 2, 1, 0 for Groups 15, 16, 17, 18 respectively, based on the octet rule). Several specific classes of hypervalent molecules exist: 1. Hypervalent iodine compounds are useful reagents in organic chemistry (e.g. Dess–Martin periodinane) 2. Tetra, penta and hexavalent phosphorus, silicon, and sulfur compounds (ex.

IntroductionSF6 GasSF6 Circuit Breaker TypesConstruction and Main ComponentsIn power systems, circuit breakers are used to switch electrical equipment and networks under normal and fault conditions. The primary function of a circuit breaker is to interrupt the flow of current (load or short circuit) by opening its contacts and thereby isolating the switched parts of the system. The design and working of a circuit breaker depend on its application and voltage rating. Moulded case technology (with air at atmospheric pressure) is used at low voltages (< 1000 V), whereas air blast and …See more on savreeGas Insulated High Voltage Switchgear, 110kv 126kv Gis Sf6 Metal … 11211517 gas insulated high voltage...110kV 126kV GIS SF6 Gas Insulated High Voltage Switchgear Metal Clad Switchgear .
