◆General

CQ3 type A.T.S intelligent dual power automatic transfer switch (hereinafter referred to as the switch),is a kind of emergency continuedpower switch,the switch is composed of circuit breaker and intelligent controller.This product employs the latest micro computer control systems core;it has advantages of electrom agnetic compatibility,strong immunity,work reliably and stably for long tem,when equipped with a largescreen LCD back light display,it can provide users with favorable man-manchine interface,convenient and intelligent operation.Therefore,it is an ideal new type of automatic transfer switching equipment with mechanical-electrical integration. 

The products are in confomity with standards of GB/T 14048.11-2008"Low-voltage switchgear and control equipment,NO.6 part;Multifunctional NO.1:automatic transfer switches"

◆Model and meanning

◆Application

This switch is suitable for the double-circuit power supply system of AC50/60Hz,rated voltage below 1000V and rated current below 63A,to realixe automatic or manual trans fer between normal (N) and standby power(R),(Main and standby power supply can be a grid,starting generator,battery,main power supply is defined by the users )then to get an ummanned transformer station for dual-power users.The product is applicable to the provisions of the state for class load user,where power failure is impemissible such as high-rise building,post and telecommunications,coal ship,ine,medical,facilities, airports,fire protection,metallurgy,chemical industry,textile,petrol.

◆Normal working conditions

●The air temperature is-5℃~+40℃,the average value with in 24 hours should not be over 35℃.

●The relative humidity should not exceed 50% at max temperature +40℃,the higher relative humidity is pemissible at lower temperature,for instance,90%at +20℃,but the condensation will be produced due to temperature change,which should be considered.

●The altitude of mounting place should not exceed 2000m.

●Classification:IV Inclination is not more than±23°.

●Pollution grade.3.

●If beyond above mentioned conditions,users should negotiate with the manufacturer,If the product is used for mining,shore oil and nudear power station,the technical agreement shall be signed separately.

◆Structure features and functions

The CQ3 switch is driven by a single motor driving,simple structure,stable and reliable switching,no noise,small impact force.The operator drive motor drive motor is performend only by current switching instant,no need to provide working current steady-state operation,obvious enregy saving,No temperature rise of fever,node welding and motor burnout phenomenon;switch with mechanical interlock protection,to ensure that the main power supply is not switched on at the same time,keep main power and standby power reliable work,mutual non-interference.The switch can load switch,can be used to manually switch handle emergency,Switch has electrical or mechanical closing instructions S.T.S control power are from the main power supply of AC 220V(Without additional control current).

The intelligent controller also provides functions with loss of pressure,phase failure control,under-voltage,delay control,generator control, fire reset fe edback signal and so on,and strong anti-interference ability,having auto-charge auto-recovery,auto-charge non-auto -fecovery and mutual standby three qoekinf moswal with common power supply,standby power supply,power,standby power supply,power standby power is divided into three kinds of stability working state.

Easy installation,control loop uses plug-in terminal connection.

Available special handle for manual conversion in manual mode.
