About the capacitor of induction furnace, how to prevent damage?


Induction furnace is a modern smelting equipment, using electromagnetic induction heating principle can achieve rapid heating and heating. And the use of the method is also very convenient, so it occupies a place in many smelting equipment.

But many manufacturers in the use of intermediate frequency furnace, occasionally there will be the phenomenon of capacitor burning. Today, the editor of Judian will analyze for you, what are the causes of induction furnace capacitance burning?

In the use of induction furnace, if there is heating and smoking of electric capacitor, the first thing to check is whether there is cathode grounding phenomenon of capacitor. In general, this phenomenon is the breakdown of the capacitor shell caused by the poor insulation of the electric capacitor.

If such phenomenon occurs, the insulation of the capacitor cabinet should be reprocessed.

In order to prevent the electric capacitor from burning out, the general melting furnace equipment has a cooling system. However, the long-term use of the furnace may lead to scale in the cooling pipe of the capacitor screen, or debris blockage in the cooling water intake system, which will lead to water shortage of the electric capacitor, resulting in heat and burn out.

Therefore, we suggest that in the process of using the furnace, we must regularly check the flow of hot cooling water at the capacitor point. If the flow is too small, we should solve it immediately so as not to cause more serious failures.

In addition to the above reasons, the voltage is too high and intermediate frequency furnace melting furnace capacitor burn out one of the reasons, the general capacitance has its rated power, and in the process of intermediate frequency furnace used as electric furnace of too high, more than the rated power is equipped with electric capacitance, also can cause breakdown voltage, and then, the phenomenon of the capacitor burn out.

The solution to this fault requires us to turn down the voltage of the melting furnace. If the voltage required for the operation is too high, we recommend replacing the electric capacitor with a model with a higher voltage tolerance class.

This is what we share today about the melting furnace capacitor burned out of the reason, capacitor as one of the important components of the furnace body power supply, must be in the process of daily use, check more, frequently replace, timely deal with the hidden dangers of safety, so as not to cause serious accidents, it can also improve the efficiency of induction furnace.
