This equipment is indoor metal armoring with drawable switchgear (hereafter refer to as switchgear 36.12klovolt three phase AC SUHI single bus bar and the single bus bar subsection system’s omplote alectricity distribution equipment is used in the power plant, small and medium–sized generator power transmission, industry and mining business power distribution as well as electrical industry system’s second transformer substation’s clectric take–over, power transmission and large–scale high pressure motor starting and so on. The purpose is to control, protect and monitor. This switch equipment is up to the standard of EC298, GB3906 and can prevent the charga from pushing and pulling the breakor, from opening and. closing the breaker, from insulation with electricity by mistaken, from earthed switch closing the breaker, from opening the switch’s interlock when it with alectricity mistakenly. It can not only use with 451 vacuum circuit–brasker, but with ABB Corporation’s VD4 vacuum circuit–breaker. It is indeed a kind of power distribution equipment with superior performance.
