Product Description
SQ5 series Automatic transfer switch mainly used for distribution or electromotor network, which under voltage 380V, rated voltage DC 220V, Rated current 16A-3200A.
Main power and standby power or mutual standby power change over system or city power and generator group overload switch-over. At the same time, it can operated under un-frequency on and off circuit act as disconnector.
Widely used at the field of important power supply site, which transport, distribution power supply system and automatization system. For fire protection,hospital,bank,building,etc, where doesn't allow power off.
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.
