An induction furnace is a modern smelting equipment that uses the electromagnetic induction heating principle to achieve rapid heating and heating. The capacitor of induction furnace is an important component of the furnace. Today, we will introduce how to prevent the capacitor of induction furnace from damaging to you.
But many manufacturers in use intermediate frequency furnaces, and occasionally there will be the phenomenon of capacitor burning. Today, the editor of Judian will analyze for you, what causes induction furnace capacitance burning.
In the use of an induction furnace, if there is heating and smoking of an electric capacitor, the first thing to check is whether there is a cathode grounding phenomenon of the capacitor. In general, this phenomenon is the capacitor shell breakdown caused by the electric capacitor's poor insulation.
If such a 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 burnout.
Therefore, we suggest that we regularly check the flow of hot cooling water at the capacitor point in using the furnace. If the flow is too small, we should solve it immediately so as not to cause more severe failures.
In addition to the above reasons, the voltage is too high, and the intermediate frequency furnace melting furnace capacitor burns out one of the reasons, the general capacitance has its rated power, and in the process of intermediate frequency furnace used as an 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 burning 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, checked more, frequently replace, and timely deal with the hidden dangers of safety, so as not to cause serious accidents, it can also improve the efficiency of induction furnace.
Welcome to pay attention to Luoyang Judian, let us provide you with more furnace services.
