Summary: Appear as what use switch of carapace of model of low pressure of high capacity of series of ABB company S, tall disjunction, and the application of the dynamoelectric operation orgnaization of form a complete set of switch of carapace of as low-pressure as this model, make use switch of low-pressure model carapace to undertake low-pressure equipment casts distribution design to become a possibility oneself.

The 400V that the article introduced a kind to come true by switch of carapace of model of series of ABB company S joins distribution system oneself fully, this system uses switch of carapace of model of low pressure of series of ABB company SACEIsomaxS relay of low voltage of dynamoelectric operation orgnaization and static state will come true, take up the space is little, easily group screen, electric equipment performance is superior. Classics try out, moving result is favorable.

Keyword: Distribution system of ABB of model carapace switch

1, foreword

As the development of modern science and technology, power user is taller and taller to the requirement of electric energy quality, make transformer substation () wait to be opposite for distribution branch of power supply successional raise taller requirement, be opposite consequently raise transformer substation () the dependability that the low-pressure place that oneself safety runs uses electric distribution system more it is important to show. Normally the low-pressure place of transformer substation is double power source to take a line with electric system design, 35kV and change below electric place often is used one advocate one equipment run mode; And 110kKV and above transformer substation often design double power source of section of the generatrix that it is sheet to cast run mode oneself fully. In the meantime, use low-pressure report bear in view of the place of 110kV transformer substation bigger, be in commonly 400A above, the frame formula switch that reason uses the tall disjunction capacity such as DW15, ME in groovy design middling will come true. And the switch of this kind of form often needs special low-pressure distribution interval. So, the low-pressure place of the 110kV that uses design of frame formula switch and above transformer substation uses electric system, cover an area of an area big, installation cost cost is high.

Appear as what use switch of carapace of model of low pressure of high capacity of series of ABB company S, tall disjunction, and the application of the dynamoelectric operation orgnaization of form a complete set of switch of carapace of as low-pressure as this model, make use switch of low-pressure model carapace to undertake low-pressure equipment casts distribution design to become a possibility oneself. This distribution system can go to the lavatory with 2 protective equipment is discharged together, consequently managing install a space, reduced installation cost cost greatly.

The 400V that the article introduced a kind to come true by switch of carapace of model of series of ABB company S joins distribution system oneself fully, this system uses switch of carapace of model of low pressure of series of ABB company SACEIsomaxS relay of low voltage of dynamoelectric operation orgnaization and static state will come true, take up the space is little, easily group screen, electric equipment performance is superior. Classics try out, moving result is favorable.
