TIANAN Double Power Automatic Transfer Switch Relief Delay Time Device
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.
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.
