Answer / naga muneendra reddy

UPS means Uninterrupted power supply.
it has a rectifier circuit, a battery bank and an inverter
circuit. battery bank is connected in parallel to the
circuit joining rectifier and inverter. normally battery
will be charging, when power fails, dc power from battery is
inverted to AC and supplied to the load.

Answer / francis.e

main parts of UPS are REACTIFIER,BATTERIES, INVERTER
Rectifier: converts the AC supply to DC sypply
Batteries: It will be charged by DC supply, and gives the
supply during the supply interruption.
Inverter: It inverts the DC to AC supply.

Answer / arun reddy l.

Hi this is Arun Reddy. UPS means Uniterrupted power supply.
The main parts are Converter,Inverter,Batteries,Rectifier.
Converter: It converts AC to DC Supply. The DC supply goes
to battery to charge.
Inverter: It converts DC to AC Supply.
Battery: It takes DC power means output of Converter & We
get DC power output from Batt. When the power comes to
Inverter it will become AC power.
Rectifier: It converts AC to DC Supply. It used Before the
Batteries in UPS System.

Thanking You.

Answer / khalidshaikh

IT IS NOT NECESSARY TO WRITE ABOUT WHAT DOES UPS STANDS FOR
OR WHAT IS ITS FUNCTION, AS FOR AS QUESTION IS CONCERNED
REPLY IS SUBMITTED AS UNDER PLEASE.

BATTERY:- FIRST OF ALL UPS CONVERTS UN INTERRUPTED AC FROM
DC, FOR WHICH WE NEED A GOOD CAPACITY BATTERY.

RECTIFIER:- WHEN BATTERY BECAME DISCHARGED AFTER RUNNING
FOR A TIME, RECTIFIER REQUIRES FOR CONVERTING SYSTEM AC TO
DC.

STEP DOWN TRANSFORMER:- SYSTEM VOLTAGE IS 220 V AC AND
BATTERY REQUIRES 12 V DC , FOR WHICH STEP DOWN TRANSFORMER
IS REQUIRED TO CONVERT THE SAME.

STEP UP TRANSFORMER:- WHEN UPS IS IN WORKING CONDITION. IT
OPERATES ON DC, AND CONVERTS 220 V AC, FOR WHICH STEP UP
TRANSFORMER IS REQUIRED.

DOUBLE CONVERSION TRANSFORMER:- SAME TRANFORMER IS MOSTLY
USED FOR STEP DOWN AND STEP UP, MEANS IN UPS WE ARE IN ONE
STATE, EITHER CHARGING BATTERY OR RECEIVING CHARGE FROM
BATTERY THROUGH THIS TRANSFORMER.

FREQUENCY CIRCUIT/ AC CONVERSION CIRCUIT/ DRIVER CIRCUIT:-

WE KNOW THAT TRANSFORMER WORKS ONLY ON AC OR VARYING
CURRENT, FOR WHICH FREQUENCY CIRCUIT CONVERTS 12 V AC AT 50
HZ FROM 12 V DC THOUGH BI STABLE MULTI VIBERATOR.AND DRIVER
CIRCUIT WHICH DRIVES STEP UP TRANDFORMER FOR CONVERSION OF
220 V AC FROM 12 V AC.

RELAYS AND CONTROL CIRCUIT:- RELAYS ARE REQUIRED TO MONITOR
AVAILABILITY OF MAINS AC AND IN CASE OF AC FAILURE STARTING
OF FREQUENCY CIRCUIT TO GENERATE UPS.

Answer / motilal sahu

INVERTING CIRCUIT IS MAIN PART

Answer / asit

unintrupted power supply. its operated as thyrister ckt.

Answer / mehboob k. panjwani

UPS stands for Uninterrupted Power Supply.
Main Parts are:
1.Transformer, used to convert 220V AC to 12V DC or vise versa
2. Circuit, used to control the monitoring and running funtions.
3. Transitors, used to smoothen the supply from AC to DC
4. Diods, to help in charging the battery
5. Rectifier, It converts AC to DC Supply.

Answer / vishal & nitish

ups stands for unninterrupted power supply. it contains a
battery a rectifier & an inverter.
battery: conserves the power supply.
rectifier: converts the ac to dc .
inverter: saves energy & converts the dc power supply to ac.

Answer / mohamed mwarasi

1. battery: conserves the power supply
2. rectifier: converts the alternating current (AC)to direct
current (DC)
3. inverter: converts the DC power supply to AC.

Answer / sandeep

UPS is a Uninterrupted power supply.It is work mainly with the helpof REACTIFIER,BATTERIES, INVERTER
Rectifier: converts the AC supply to DC sypply
Batteries: It will be charged by DC supply, and gives the
supply during the supply interruption.
Inverter: It inverts the DC to AC supply.We
get DC power output from Batt. When the power comes to
Inverter it will become AC power.

1 Answers  

sir , what happen if we decrease ( approx 3 inch ) the lenth of shaft in 110KW Induction , three phase motor. actually a 110KW motor is couppled with star couplling to 120TR compressor. When we doing maintenance in compressor it is required to skid the motor backword and resulting dis- alightnment . so we want to change the tyre coupling in place of existing coupling. so it is required to cut off the rotor aprox 3 inch form driving side.
