There are four connection methods for the coil plate of the induction cooker

In fact, to know the direction of the wire winding or wiring, you have to use the physics knowledge that we have learned in junior high school or high school, such as Ampere (the right hand spiral rule), and the right hand spiral rule is the right hand grasping, the curved four fingers Indicates the direction of rotation, the thumb indicates the direction that the spiral advances. For a linear current, the direction of the spiral advance (the direction of the thumb) is the direction of the current, and the direction of the magnetic field generated around it is the direction of the spiral rotating to the right (the direction in which four fingers bend ) Direction. For a circular current, the direction of helical rotation (the direction in which four fingers bend) is the direction of the current, and the direction of the helical propulsion (referred to by the thumb) is the direction of the magnetic field on the central axis.


The magnetic field direction of the spiral tube current is also the same as the judgment method of the ring current.


According to the above laws, we briefly describe:


With your right hand on the reel, extend your thumb upwards (because the pot is on top), then the direction pointed by the four fingers is the direction of the current. When the current direction is determined, you know that the pin is connected to 300V.


In the maintenance, most induction cookers are generally connected to the inner ring at 300V, and the outer ring is connected to the C pole of the IGBT tube. Most models can be connected in both forward and reverse directions, but some can not be connected casually. There is a large current that damages the 1GBT tube failure, so make a mark during maintenance and try to avoid reverse connection.


There are four connection methods for electromagnetic reels:


1. The coil of the reel is from the inner counterclockwise flat type. The inner ring of the model is generally connected to + 300V at the beginning, and the outer ring is connected to the c pole of the gate control tube at the end.


2. For the organic type inner ring, the leading end is connected to the C pole of the gate control tube, and the outer ring leading end is connected to the end + 300V.


3. The coil of the reel is from the inner clockwise to the inner side of the model. The inner ring is usually connected to + 300V at the beginning, and the outer ring is connected to the c pole of the gate control tube at the end.


4. For the organic type inner ring, the leading end is connected to the c-pole of the gate control tube, and the leading end of the outer ring is connected to the end + 300V.
