Improvement of capacitor connection failure in metal melting furnace
Improvement of capacitor connection failure in metal melting furnace
Faults frequently occur in the operation of the धातु पिघने भट्ठी. The specific manifestation is: overcurrent. Analysis: 70% of the faults are on the water-cooled capacitor. The reason is that the water-cooled capacitor is cooled by water, and the cooling water pipe is a plastic pipe. The capacitor current is large during operation. The connection part often leaks water and water seepage phenomenon is more frequent. The connection between the water-cooled capacitor and the busbar is soft. It will turn blue, black, poor contact, sparks, burn copper wire, burn out capacitors, cause over-current action and be forced to shut down the furnace. After analysis and research, I changed the copper wire that is afraid of water into a copper row connection. I repeated experiments on a single furnace and the result was very successful. After being certified by the workshop leader, two metal melting furnaces were modified, which greatly reduced the failure rate.
