automatic transfer switch(ATS)

  The system for dual power change-overswitch ZQ2 is designed to provide continuous powersupply and two electrical souces automatic switch in case offailure or deviation from the set parameters.
The sysytem for dual power change-over switchconsists of two high capacity circuit breakers mounted ona metal frame connected with common operating mechanism andcontrolled by a command devices that controls the system parameterscorrespondence

* Swithcing on/off heavy loaded electrical circuits at mainpower supply discrepancy
* Switching to dual power change-over at power supply phaselack
* Breaking of electrical circuits and control of powerfulconsumers
* Used as a main breaker in housing or industrial distributinginstallations supplied with a generator or a second power supplysource (hospitals ,post office,miliary sites,control rooms)
* Remarkable with high reliability of current characteristics
* Control:motor
* Controls the following circuit parameters
- presence of the three phases
- the phase voltage to be in the set limits 
- overload
- short circuit at the outlet

* Rated operating voltage:690V.50/60Hz
* Surge voltage wear resistance:8000V
* Joining termainal:bolt connection with 4 bolts to the powersupply rail
* Connecting:
- copper rails
- flexible or rigid conductors
* Electrical wear resistance(number of cyles):10000
* Mechanical wear resistance(number of cyles):20000
* IP code: IP21
* Mounting:
- clamping with bolts
- mounting position:vertical gradient-maximum 5o
* Plastic material of the breakers of UV rays and non-flammable
* Ambient temperature: -10oC 45oC
* Installation altitude:up to 2000m

* Overload protection
* Instantaneous short circuit protection
* Under phase protection
* Possibility for setting the change-over time between the twosources -min 3s
* Possibility for automatic switch-over to the main power supplysource after restoring its parameters

The sysytem for dual power change-over switch is offered intwo types:
- with display(controldevice)mounted on the mounting plate(integrated type)
- with separated control  dispaly...
