Thus it is notNecessary to provide external controller. This truly electrome chemically integrated automaticChange-over switch has the following functions, such as voltage detection, frequency detection,Communication inferface, electrical and mechanical interlocking etc., So automatic control,Electrical remote control and emergency manual control can be performed.The operation is carried out through the logic control control board, which gives variousCommands to control the motor and gear-box. The motor drives the accelerator which can takeSeich-spring power accumulating and instantaneous releade, swifty truns making and breaking theCircuit or makes circuit switching. The visible operation status can help you to perform safeSeparation, increasing extremely the various electrical and mechanical performance.The shell of switch HGLD 1, HGLD 2 is made of metal, being small and compact, While the shellOf swich HGLD is made of different materials: Its control section is made of metal, but theSwitching section is made of glassfibre unsaturated polyester resin, having stronger dielectricProperty and protective capability as well as safe operation performanceThe kind of switch is suitable for the automatic change-over of the main power source and theSecondary power supply system or the automatic change-over and safe separation of the 2setsOf load-equipment. This kind of switch has beautiful, novel and simple structure, a small volumeBut complete functions, being the best choice among congener of products.Example for model selectionHGLD1-100/A III~380V In 50AAutomatic change-over switch, Appointed clarify current is 100A, AC rate voltage 380V,Rate current 50A, 4poles(3 poles +on and off neutral pole), Suitable forautomatic changeAnd automatic recovery of municipal power oil generator power supply system.HGLD Series Automatic Change-Over Switch Complies with the Following Standards:IEC60947-1(1998)Low-voltage switchgear and controlgear, part one: General Rules IEC60947-3(1999) Low-voltageSwitchgear and control gear, switches, disconnetors, switch-disconnectors and fuse-combinationUnitsIEC60947-6(1999)Low-voltage switch equipment and control equipment multi-function-switch automatic change-over switch electrical deviceNational Standard:GB/T14048.1-2002Low-voltage switchgear and controlgear, part one: General RulesGB14048.3-2002Low-voltage switchgear and control gear, switches, disconneetors, switch-disconnectors and fuse-combination unitsGB14048.11-2002Low-voltage switch equipment and control equipment multi-function-switch automatic changeover switch electrical deviceHGLD series automatic transfer switch is mainly used in AC 50Hz, rated voltage of 380V DC rated voltage of 220V, load switch a preparation of a master or mutual standby power supply switching system and the city electricity and the generator rated current of 16 to 3200A distribution or motor network. Can also be used for less frequent switching on and off circuit and circuit isolation in.Products are widely used in fire fighting, hospitals, banks, and other high-rise buildings are not allowed to cut off power supply of important places of transmission and distribution system and automation systemTheswitchhas3polesor4poles(3poles+onoroffneutralpole).27currentgradescanbedividedinto16A20A25A32A40A50A63A80A100A125A160A200A225A250A315A350A400A450A500A630A800A1000A1250A1600A2000A2500A3200A.BasicType:Mainstandbypower,self-cast,selfreset.Type1,100Abelow,citypower-citypower,self-cast,selfreset,twowaypowerthreephaseshortphasetesting.Above125A,citypower-citypower,mainandstandbyormutualpowercandoselection,Self-cast,twowaypowerthreephasechecking.TypeII:citypower-citypower,mainandstandbyormutualpowersupplycandoselection(thatisself-castingselfresetorself-castingwithoutselfreset),twowaypowerthreephaseAndlackphase,overloadvoltagechecking.TypeIII:citypower-Oilmachine,selfcastingselfreset,twowaypowersupplythreephaseandlackphase,overloadvoltage,oilmachinefrequencytesting.BasictypeswitchcontrolcharacteristicSuitableforthetwowaymainandstandbypowersystem,selfcastingandselfrest.Itcanexpandfunctionbyouterconnection.TypeIswitchcontrolcharacteristic:100Abelow:A:Suitablefortwowaymainandstandbypowersystem;B:Itwillswitchontostandbypowersupplycircuitafterswitchdelay(settingrange1-16S)Whenthemainpowersupplycircuitshortcircuitandloop(switchofforshortphase).
