Stationary type indoor communicates metal obturate ring-operated network switch equipment
Product Model: HXGN15A-12(F.R)
Product Name: Stationary type indoor communicates metal obturate ring-operated network switch equipment

Scope of application HXGNl5A a 12(F.R)Type stationary type communicates metal obturate ring-operated network switch equipment ( Short form" Ring-operated network cupboard " ) , Are for intercity network alter and construct need but natal new-typed high pressure switch cabinet. 。Also as open break load current and short circuit current and close equal to short circuit current of use in power supply system, Will fitting be used for communicate 3 ~ 10KV/ 50Hz ’s distributes in system. Extensively be used for intercity network construct and alter engineering, Industrial and mining enterprises, High-rise and public facility, As ring-operated network supply electricity cell and end device, Rise electric energy’s allocation, Control and electric apparatus ’s protect effect, Also can install at pre-installed in transformer station. This ring-operated network cupboard match vacuum load-break switch, Spring grasps move agency, Should agency already can independent manual operation, Also can dynamoelectric operation. Earth switch and disconnected switch match hand power grasp move agency, This ring-operated network cupboard whole sex strong, Cubage small, Have not burn and blast danger, Possess dependable " Five prevent " Function. This ring-operated network cupboard accord with GB3906 ( ( 3 ~ 35KV will communicate metal obturate switch equipment",IEC60420 ( ( High pressure communicates load-break switch a fuse utensil combine electric appliances" Normative relevance stipulation.

ring-operated network will supply electricity principle
Ring-operated network supplies electricity ordinary by three basic cells composings ( Sees picture 7) Enters win cupboard as ring-operated network cell, Ases appoint a line appear breakdown time, Can in time isolation, And by another a cell ensure consumer transformer offshoot continuously power supply. Subscriber loop ring-operated network cupboard to transformer rise protect and isolation effect, Convenients for maintain overhaul.
Ring-operated network cupboard can Arbitrary extension, And can according to consumer request by basic cell compose many kinds combination schemes.
