Battery charging

 Battery charging:


    Battery charging means that the secondary cell density is less than 0.8 or it is charged immediately to recharge the battery.
                      Generally, DC to charge secondary cell. Is used but every space is in DC Since there is no getting it, AC needs to be converted into DC and then the battery is charged. This type of tangor bulb type rectifier is usually used, The motor generator set is used for this method where the battery is charged.
                     For this, the connection of the positive terminal of the DC source should be done with the positive terminal of the battery and the connection of the negative negative terminal of the source should be done with the negative negative terminal of the battery. If the polarity succeeds, then the DC ends the two ends of the source connecting the battery Negative wires submersing in acidic water or submerged water will have a higher level of bubbles. So the concept of polio Sector.
                      Now we will learn about the methods of battery charging which are used in the following two types of methods.

1.constant current charging method and
2.constant volteg charging method

1.constant current charging method :



                                       This method is used where high voltage DC cleaning is found, but the voltage of the battery should be low in such circumstances. Now the battery is not emf less compared to the supply voltage. So that in the battery series Lamp or Resistance is connected. That controls the charging current. This method is not so useful due to loss in this way.
                                       By this method, many batteries attached to the series can be charged. However, the battery gets disconnected due to the battery voltage more than the supply voltage voltage.
                                     Charging current I = V-Eb / R + r

                                                                                           V = DC Supply voltage
                                                                                        Eb = Counter emf of battery
                                                                                          R = Outer barrier of lamp or resistor
                                                                                            r = Internal barrier of battery

 Advantages and disadvantages:


      This way, the battery charging increases the life expectancy but it takes more time to charge in charging. It is often disadvantaged to check the value of charging current frequently.


2.constant current charging method 


                      In this way, the charging or supply voltage for the full time of charging is kept constant and therefore it is known as a steady voltage method. Change in the value of the charging current, by controlling the Field Regulator of Dynamo or by controlling the speed of the primary movers. Initially the charging current value is too high or higher, which decreases in battery emf This is a common way to charge the battery

Advantages and disadvantages:


         This way, it takes less time to charge than charging that the battery is charged much faster than this method, whereas this method reduces the efficiency of the battery and reduces battery life.
                            However, battery can also be charged using AC solution. This type of method is used only for D.C.Apliance. However, if the AC supply is available only then in the case of the first receiptfire. AC supply conversion is done by DC supply in the use of the Rectifier full wave or the Half Wave. In this way, the value of the first voltage is reduced by the transformer to DC

ERTHING

ERTHING                        Electricity is beneficial for us, but its loss is even more. Electricity can take our lives even if it does not go well. Now we can not get away from electricity because electricity has become part of our life. Light in the darkness, fan in the heat, so much of the electricity around us that we They even use it inadvertently. Along with this, the risk goes up. For this reason, we must definitely adopt a path of goodwill which can secure us and our own electricity so we must definitely do our work in our home to avoid all these. But first, do you know what the meaning is?  What is Erthing?            We have so many electric appliances in our house around us that sometimes we have been using it. Therefore the electrical equipment is in contact with our body, and therefore whenever there is a fault in the instrument then the body of the instrument comes in contact with us, so that the current passes through our body and we feel shock O

Distribution Transformer and Power Transformer

Distribution Transformer:                                     The transformer is used in the distribution of electrical energy. It is called Distribution Transformer. Its rating is 200 KVA and it is a step down type. In this transformer whether the load is loaded or not, it is functioning 24 hours a day. This means that iron lasts continuously throughout the day while copper is based on the load load. So much so that the load more loads of copper loses and loads less as copper Iron deficiency in such transformer should be lower than Copper Loss. In other words, the transformer's efficiency should be greater on the 50% load. Such transformer's voltage regulation should be good. Power Transformer:                                      The transformer that is used for the transmission of electrical energy is called a power transformer. The rating of this transformer is 200KVA. Power transformer can be used to step up or step down the voltage on both ends of the power l

D.C 3 POINT STARTER

                                 It can also be called a three point starter. Its structure is shown in Figure. To start the motor, the handle is moved from off position to the first contact position. The total obstacle is in the armature circuit, the field connection is connected directly to the supply through a volt coil. Comes in as soon as the speed of the motor increases in the same way as the archete back emf emits and decreases in the value of current Now the handle is moved to the second step. Again this type of function will be done eventually at the last step of the handle. This time the armature will connect directly to the supply and this time the handle does not come with a no-volt coil. The magnet will hold the handle in the walt coil, and the motor will not need to hold the handle to continue and the motor will rotate in full speed.                   Mechanism of 3 points Starter is done so that if the magnetism of the nvc coil is exhausted for any reason, and the
