TIANAN Double Power Automatic Transfer Switch Relief Delay Time Device
Product features:
A. Structure:
TANQ2 Series Double Power Automatic Transfer Switch is a transfer
system made up of two major parts: Main part and automatic
controller. The two parts are linked by special cable up to 2m
long. The main part is made up of two circuit breakers with
power-driven mechanism and accessories (auxiliary contact, alarm
contact), mechanical interlock mechanism, fuse, terminals etc. The
circuit breakers type can be TANM1 and TANM2.
B. Performance
The automatic controller detects the phase voltage of two power
supply, if the voltage is 110% higher than the rated voltage, it
will be judged as over voltage; If the voltage is 85% lower than
the rated voltage, it will be judged as undervoltage. The logic
circuit will act by the detecting result and display the result on
the panel through LBD. According to function, the automatic
controller can be divided into three kinds: Automatic change and
automatic recovery controller (R), automatic change controller (S)
and municipal power-generator controller (F).
When the primary power is over-voltage, undervoltage or phase
shortage, the automatic change and automatic recovery controller
(TANQ2R) will change to the secondary power through the setting
delay-time device; When the primary power gets right, the
controller will change to the primary power. Once the secondary
power is abnormal, the controller will alarm.
When the primary power is over-voltage, undervoltage or phase
shortage, the automatic change controller (TANQ2S) will change to
the secondary power through the setting delay-time device; When the
primary power gets right, the controller
Cant recover automatically. Only the secondary power is off, can it
change to the primary power.
The municipal power-generator controller (TANQ2F) is suitable for
the automatic change between the municipal power supply and
generator supply. When there is something wrong with the municipal
power supply, the controller sends out the signal of starting the
generator through the delay-time device. When the voltage of the
generator become stable, first cut off the load circuit, send out
the uninstall signal through the delay-time device, uninstall the
subordinate load, and then turn-on the generator supply through
turn-on delay-time. When the voltage of the municipal power gets
right, first cut off the generator supply through the relief
delay-time device, then return to turn-on time-delay and change to
the municipal power supply automatically.
