MBQ3 - Automatic Transformer Switch

 

Application:
MBQ3 series automatic transfer switch(A.T.S) suits for the transfer between two powers(Primary power and secondary power),whose rated voltage is beneath 600V(AC),control voltage is under AC220V.It is the new pro duct to replace the conventional one which made up of AC contactor and circuit breaker,and widely used in hospitals,hotels,markerts,post and telecommunications,fire,high building,industrial assembly line,etc.

Features and characteristics:
1.Excitation type electrorriagnteism driving,direct current pulse operation,transfer fast,the coil will not give out heat and cause noise, can save the energy.
2.Two operation modes:power-operated and hand-operated.
3.Having electric interlocker and mechanical interlocker,this can ensure two powers not be electrified at the same time.
4.Big-size contacts have steady and reliable electric conductivity.
5.Good arc extinguishing feature can make the switch be operated even it is in power.
6.Rated insulation voltage:660V;Rated voltage:380V 660V;Time of change over;0.1S

Structure and operation principle:
1.MBQ3 series automatic transfer switch is the real and integral designing switch,but not the conventional combination switch.The switch is made up of main contact system and electric & mechanical interfockers control system which can ensure two powers not be electrified at the same time.The main contacts has,its own arc extinguish chamber.This switch can be transferred by the hand.
2.Excitation type electromagenteism straight-line driving make the switch transfer more reliable and fast,and be aseismatic.When the switch is in transferring,the coil may be electrification(the time is less than 0.1S),and when completes,the coil and other control parts are out of electricity.
3.In normal state,the primary power is working.If the primary power happens to be trouble such as power cut,over voltage,under voltage or phase failure,it automatically change over to the secondary power passed by the automatic controller,when recovering to the normal state,it returns to the primary power agair.Meanwhile,if the secondary power in trouble,the controller will send out alarm to warn people to repair it timely.
