As mentioned above, the gas content and slag content in the electrolytic aluminum body melt are far greater than those in the remelted aluminum liquid. The solubility of the gas dissolved in the aluminum liquid decreases as the temperature of the melt decreases. During the casting or rolling process, the melt cools rapidly and solidifies into a solid, [...]
1 Characteristics of electrolytic aluminum liquid Electrolytic aluminum liquid is produced by high-temperature electrolysis of aluminum oxide in the presence of certain electrolytes (such as cryolite, etc.) using a special process. The temperature of electrolytic aluminum liquid is generally between 920 and 950°C, and the residence time in the tank is long. The aluminum liquid is extracted from the [...]
1.Operation and maintenance after the shunt capacitor tripping During the operation of the DC system, if the AC filter or shunt capacitor tripping and the stage III directly trips due to a fault, the operator should carry out on-site disposal in an orderly manner according to the following points: (1) After the faulty filter or shunt capacitor [...]
1. Analysis of common capacitor failures causes of reactors and capacitors The main operating failure of dry-type air-core reactors is insulation breakdown between coil turns. The causes of failure include damp coils or insulation weaknesses, local discharge arc burnout, local overheating insulation breakdown, overvoltage, short circuit caused by small animals, and deformation and damage of coils [...]
1 Types of aluminum-based solid solutions in electrolytic capacitor aluminum foil Aluminum foil for electrolytic capacitors usually needs to be made of high-purity aluminum. However, even the highest purity aluminum inevitably contains a small amount of impurity elements. Sometimes it is necessary to artificially add a small amount of alloying elements to the aluminum foil for [...]
