panel wiring of different types of motor


* DOL Starter with delta connection 415v, 5 HP

~  Three phases from the busbar go to the main switch.

~  The output ends of the main switch are connected to the input of the DOL starter A phase emitter goes.  A voltmeter is connected between the two phases.  Three phases exit from the starter.

~ The wiring diagram does not have an ammeter or voltmeter decimal.  These three phases exit the panel and pass through the underground metal cod to reach the motor.

~ The starter is mounted on the panel.  Ammeter and voltmeter and main switch are also mounted on the panel.  The dotted line in the diagram means the connection is ten.

~ With a supply of 415 v, 3 phase system, the range of voltmeter is 0-500 V. Use the thumb rule to find the range of an emitter.  The motor is 5 hp so 5 x 1.5 = 7.5 A.

~ Thus the range of emitter can be kept 0-10 A or 0-15 A.  Since the main switch controls only one motor here  Rating 30 A 600 V can be maintained.

* star - delta starter with 415v , 3 phase, 25 H

~ three phase induction motor with a star detector sputter.  Three phases from the busbar pass through the main switch to the input end of the starter.  

~ A phase ammeter is connected, a voltmeter is connected to a two phase echo.  The wiring diagram does not have an emitter or voltmeter.  Six wires protrude from the sweater.

~ This wire passes through the metal conduit to the terminal box of the motor, the dotted line is the earthly connection.  The range of the voltmeter should be 0.500 v. 

~ If we determine the range of the emitter, the full load current of the motor of 25 shares power is 25 x 15 = 375 A.  

~ So the engine of the emitter is 950 A and the fire of the main switch is 60 A. 500 v.in laboratory use sequral gauge motor for DC 230v and induction motor is used for generator

~  The wiring diagram of the panel is shown in Figure 1.106 and the layout of the panel is shown in Figure 1.107.  415v three phase supply comes through the main switch.

~ This supply is 415 V AC.  Come on the bus.  Selector switch |  The voltage between RY, YB and BR is selected and measured with a voltmeter v.

~  The pilot lamp is for R, Y, B ,.  Main switch 2 and star - Delta starter Chu motor is supplied.  D.C. with motor.  The compound generator is coupled.  D.C. with field regulator R.  The voltage is adjusted to the desired value.  

~  Voltage is measured with a voltmeter V.  DC with emitter A  The load current of the generator is measured.  The pilot lamp indicates the presence of DC voltage.  

~ The transformer is supplied through Main Switch 4. 230 v Three Phase AC through Main Switch 5.  The supply is taken out.

~ Volt e is selected through selector switch 2 and measured through voltmeter v.  Pilot lamps R, Y., B, to 230 V A.C.  The presence of supply is indicated.  The dotted lines show the earth. 


* DC shunt motor

~ 3 phase alternator is crippled with shunt meter, chemical management (bit travel) is 1.p h  Dwan [0.8 indicates the presence of supply.  H. through the main switch.  Shunt loss 2.m.  Get supply.  18 Runt pea 

~ The motor is turned on by the starter, the speed of the motor can be adjusted by the field regulator R of meter v, 2.c.  Measures voltage, emitter A, current taken from the supply is given by the motor, Mr. phase voltage is generated by the deter.

~  Voltage meter v, e lt voltage is measured by measuring voltage with selector switch.  Frequency meter F measures the frequency of the voltage generated.  Three lamps show the presence of  Phase.  AC through Main Switch 2. 

~ The supply is given to the load.  A terminal is provided to connect the load, the load current is supplied by the emitter A2.

* Application of electric control panel

~ Tools such as D.C.  Motor, d.  C.  Generator is used for induction control.  From the control of a small motor to the use of an electrical control panel, the control panel is useful for the control of tangled circuits of electrical motors, synchronous motors, transformers, alternators, etc. 

~ Includes main switch, starter, emitter and voltmeter to control a small motor.  In addition to starting the motor, speed control is also required.  Process control often requires that one motor be switched on and then another.

~ This is called interlocking.  Some processes are divided into four or five parts.  Each part has a certain duration.  This period is obtained by the timer.
