Product introduction
Electromagnetic coil is one of the commonly used components in many electronic products, household appliances and instruments. It mainly works by using the principle of electromagnetic induction. Its electrical characteristics are low frequency pass and high frequency stop. Among them, when the high-frequency signal passes through the element, it will encounter great resistance, which makes it difficult for the high-frequency signal to pass through, while the low-frequency signal will encounter less resistance when passing through the element, so the low-frequency signal can easily pass through it. Its resistance to direct current is basically zero.
of product damage
If the ambient temperature of the valve body is relatively high, it will also lead to an increase in the temperature of the coil, and the coil itself will generate heat during operation. There are many reasons for coil damage. How to judge its quality? Judgment of coil open circuit or short circuit: the resistance of valve body can be measured by multimeter, and the resistance can be calculated by combining the coil power. If the coil resistance is infinite, the open circuit is broken, and if the resistance tends to zero, the short circuit is broken. Test whether there is magnetic force: normally supply power to the coil, prepare iron products, and put the iron products on the valve body. If the iron products can be absorbed after being electrified, it means it is good, otherwise it means it is broken.
Operating frequency is too high
Frequent operation will also cause damage to the coil, and if the cross section of the iron core is uneven for a long time during operation, it will also cause damage to the coil.
Mechanical failure
Common faults include: the contactor and the iron core can't be attracted, the contactor contact is deformed, and there are foreign objects between the contact, the spring and the static and dynamic iron core, all of which can cause the coil to be damaged and unusable.Operating frequency is too high
