understanding the relationship star - delta
Star of origin of the relationship (connection) that star-shaped
Delta origin of the relationship who is triangular.
So if translated into Indonesian to be the Star-delta
Function (point):
1. the load.
In large electric motors who usually wired 6 = UVW & XYZ, whendirectly connected Delta, then the flow beginning at the start, will be very large, can reach 6x label.
Using Star-Delta starter system (using the circuit-equipped with a timer between Star and Delta connection), then the initial current(Start) can be mitigated to a minimum. So Star Delta function on electric motor is starting to dampen the curent (ampere currentsat start).
2 Resources.
A Generator who has output cable 6 pieces, and accompanied by a description can be 220V or 380V output alternatives can be selected, how the needs voltage.
Here is a picture of the control circuit.
Look at the picture again relationship has delta star let me be clear from the preceding article picture below:
the picture. star and delta wiring
fig. The main circuit wiring star delta
explanation:
From the picture above can be seen that the star delta wiringusing 3 pieces consisting of a main contactor K1 (main input) K2(dash star) and K3 (delta circuit). And all that is calledjugaRangkaian Main, which is basically an understanding has been discussed in previous articles.
In the figure, when K1 and K2 on or changed to NC then therelationship that occurs in a motor-circuit star, and as a NO thenK2 K3 at the same time the NC. And these changes cause the circuit to the motor into the delta circuit.
How do we make the K1, K2 and K3 works automatically changeinto star-delta motor circuit?
Note the picture below:
gbr. wiring diagram star delta
Pictured above is a picture of star delta wiring diagram that is a blend of interlocking contactors and NO and NC function of thetimer. Consider once again the picture below, which is anexplanation of the picture above.
fig. explanation of star delta wiring diagram
In the pink box is the wiring diagram of interlocking contactor, and the green box that is working and functions of NO and NC on the timer. When the ON button is pressed then K1 will work, as well as T and K2 (dash star). In this case K2 will work because it is connected to the NC of T, T will work at the same time and count the units of time previously set. Where the expiration of the time itNCnya ketapan will turn into NO and vice versa. The change is utilized to turn the K3 (delta circuit). And wiring diagrams are also known as the concatenation controller.
As the finalization of star delta wiring diagram of this, then I add the NC on K2 and K3 are interlocked at each kontaktornya. The electrical current will flow first to the NC before entering the coilK2, K3, and vice versa. This is solely to avoid the occurrence ofboth contactors were working simultaneously in case of short circuit, which can cause damage to the circuit Primarily, as shown below.

The series begins with a star delta star circuit first, only thenconnected delta. Graphically as follows:
