Product Descriptions
| Product Outline |
| SGLD automatic change-over switch(ATSE)integrates switch and logic control,thus it is not necessary to provide external controller. This truly electromechanically integrated automatic change-over switch has the following functions such as voltage detection,frequency detection,communication interface,electrical and mechanical interlocking etc.,so,automatic control,electrical remote control and emerge- ncy manual control can be performed. The operation is carried out through the logic control board,which gives various commands to control the motor and gear-box.The motor drives the accelerator which can take switch-spring power accumulating and instantaneous release,swiftly turns making and breaking the circuit or makes circuit switching.The visible operation status can help you to perform safe separation,increasing extremely the various electrical and mechanical performance. Which the shell of switch SGLD is made of different materials:its control section is made of metal,but the switching section is made of glass-fibre unsaturated polyester resin,having stronger dielectric property and protective capability as well as safe operation performance. This kind of switch is suitable for the automatic changeover of the main power source and the secondary power source of the power supply system of the automatic change-over and safe separation of the 2 sets of load-equipment. This kind of switch has a beautiful,novel and simple structure,a small volume but complete functions,being the best choice among congeneric of products. SGLD Series had been already passed the detection of EMC. |
| SGLD-100/4～380V In 50A The automatic change-over switch,the initial heat electric current 100 amperes,rated AC voltage 380V,the nominal current 50 amperes,4poles (3poles+break neutrality pole)suitable for city electricity-city electricity system’s automatic switch and self-reset. |

| Performance and characteristic |
| It adopted double complex contact,horizontal and vertical type framework,Micro motor pre-saving and Micro electronic control technical,basically,it have come to"Zero"arc(No Arc Chute); It adopt reliable machine interlock and electric interlock,the elecutive union parts adopt independency overload disconnect switch,it makes more reliable and safety; Adopt"Zero"technique,it can force to set"zero"under emergenncy situation(break off two way power supply at the same time),meet the requirement of fire protection linkage; Operate overload disconnect switch change over adopt singleness electromotor drive,switch over smooth and reliable,no noise,little wallop; Operate machine drive motor use only under the executive overload disconnect switch change over instantaneouse current across,outstanding energy saving; Perform overload disconnect switch with mechanism interlock device,it ensure the common use ,standby power working reliable and not interference; Distinct On and Off position indicator/padlock functionetc.,safe reallze the disconnect between electric power and overload; High security,high automatization,high reliable,use life more than 5000 times; Machine ＆ Electricity perfect desigh,On-Off changeover nicety、agility/smooth,adopt interm、national advanced logical control technique,high anti-interference and nointerference outside; It include main power close,standby power separate;main power separate;standby power close;main、standby power all break off and steady working(I-0-II). Easy installation,control loop adopt terminal connection and insert. Four kind of operation function;emergency manual operation、electromotion remote control operation、automatic control state emergency off opeartion 、automatic control operation. |
| Product Usage |
| SGLD Series automatic change over switch mainly suitable for distribution or electromotor network,which under AC 50Hz,rated voltage 380V,rated voltage DC220V,rated current 16～1600A,main power andstandby power or mutual standby power change over system or city power and generator group overload switch-over system or city power and generator group overload switch-over.At the same time,it can operated under un-frequency On and Off cicruit act as disconnector. Such products are widely used at the field of lmportant Power supply site,which transport,distribution power supply system and automatization.system.for Fire Proection、Band、Building etc.,which doesn’t allowed power off |
| Cortrol Characteristic |
| The switch has 3 poles or 4 poles (3 poles+on or off neutral pole). 27 current grades can be divided into 16A、20A、25A、32A、40A、50A、63A、80A、100A、125A、160A、200A、225A、250A、315A、350A、400A、450A、500A、630A、800A、1000A、1250A、1600A、2000A、2500A、3200A. Basic Type:Mainstandby power,self-cast,self reset. Intelligent type:Four kind of working patterns for selection 1.Self-switch and self-reset:suitable in the city electricity-city electricity.,two circuit power,three phase of lack,over and low voltage examinaiton. 2.Self-switch,not self-reset:suitable in the city electricity-city electricity.,two circuit power,three phase of lack,over and low voltage examinaiton. 3.City electrical Generator:suitable in the city electricity-kerosene engine,self-switch and self-reset two circuit power three phase lack,over voltage examination. 4.Instrument display:only for show. Basic type switch control characteristic 1.Suitable in the two circuit of main and prepare electrical power,self-switch and self-reset; 2.External connection carries on the function expansion. Suitable in the two circuit of main and prepare electrical power Intelligent type switch control characteristic; 1、Self switch and self reset when the main when the main power supply circuit loop breaks down(lack phase,over voltage)the switch(to be possible set 0～999S)after transformation time delay T1 to automatically changeover into the spare power supply circuit loop. When the main electrical power supply loop recover normal,switch return time delay T2(may set 0～999S)automatically back to the main power loopl 2.Self switch no self reset Suitable in the two circuit city electricity mutually backup system When I route power circuit failure(lack phase,over voltage);The switch(may set 0～999S)after transformation time delay T1 automatically changeover into II Road power circuit;When the I route power circit restores and become normal,the switch does not returns I Road,only then in route II power failure,the switch returns time delay T2(may set 0～999S)to automatically returns I Road power circuit. 3.City electrical generator Is suitable supplies power primarily in the city electricity,the power set for the spare power supply system.When the city electricity breaks don,the switch controller first sends cut the start kerosene engine signal,the switch(i.e.Warm machine time adjustable 0～, 999S)transfer automatically after transformation time delay T1 into the kerosene engine power supply retrun route.I When the city electricity restores is normal,the switch after returns by the delay T2(may set0～999S)automatically changeover returns to the city electricity power supply,after then cold machine time delay T3(may set0～999S)again,the controller sends out the shutting down kerosene engine signal.The city electricity,the kerosene engine have three-phase lack,three-phase low and over voltage examination function etc. |
