The automobile ignition coil winding machine always burns out. What is the reason?
Automobile ignition coil winding machine
1.the principle of automobile ignition coil winding machine
It is composed of a main coil, a secondary wire coil, a magnetic core, a switching transistor and other auxiliary components. The main coil is charged by the battery, the secondary wire coil is ignited by a spark plug, and the triode is responsible for switching. The charging time is controlled by battery voltage and engine speed to ensure the same energy every time. There are two types of ignition coils: 3-wire and 4-wire. 3 wires are power supply positive, negative, switch control (ECU command), 4 wires are equipped with ignition detection wire, which can detect whether the spark plug is ignited (whether the secondary wire coil has discharge current).
To put it simply, the automobile ignition coil winding machine is a transformer, which boosts the voltage of tens of volts to tens of thousands of volts, but the voltage input to the primary coil is provided by the electronic igniter.
2. Burning out of automobile ignition coil winding machine
The main reason for the burn-out of the automobile ignition coil winding machine is the aging and breakdown of the insulation layer or the damage of the switching transistor. The large gap of the spark plug causes the main coil to load and heat, and the insulation layer is aging quickly. The spark plug gap is small, resulting in high discharge current, secondary coil heating, and rapid aging of the insulation layer. The service life of the assembled ignition coil may be short, such as poor durability of the insulation material, large internal resistance and heat generation of the coil, and low quality of the triode.
3. If the car ignition coil winding machine always burns out, it will burn out soon after replacement. What are the reasons? The following summarizes some:
1）. Let's look at the generator problem first. If the power generation is too high and the load is too heavy, the ignition coil is easily burned out. However, if the power generation is too high, it will often damage the body electrical appliances such as light bulbs; of course, the quality of the accessories is not ruled out, so the power generation should be measured first.
2）. If the spark plug gap is too large, adjust the gap or replace the spark plug;
3）. The quality of gasoline is not good, try to change to high-quality gasoline;
4）. If the cylinder compression ratio is wrong, adjust the compression ratio;
5）. If there is a program failure on the computer board, you can go to the repair shop to check the car with the computer and clear the error message. If it doesn't work, there may be a problem with your car's transmission.
7. The power supply voltage is unstable;
6）.. If the resistance of the high-voltage line is abnormal, replace the high-voltage line;
7）. Secondary short circuit phenomenon;
8）.. The primary current of the ignition controller is too high, which causes the ignition coil to overheat;
9）. There are problems under high temperature and high pressure waves, and the work is not good;
10）. The small chance is the coil itself, you can try other brands;
11）. Firearms integrated block is not easy to use;
The automobile ignition coil winding machine itself is a transformer, just like the transformer in household appliances. When the voltage changes within the specified range, the transformer will not be burned out. Usually burning the transformer will only cause this situation when the transformer is overloaded. Therefore, when solving this problem, we should try our best to find out the cause of component overload or aging.
