Abstract

The invention relates to an insulation and voltage resistance experiment method of an electrolytic direct current system. A rectifier unit consists of a rectifier cabinet A and a rectifier cabinet B; output positive busbars of the rectifier cabinets A and B are connected with each other in parallel, and output negative busbars of the rectifier cabinets A and B are connected with each other in series; the output ends of the positive busbars, connected with each other in parallel, of the rectifier cabinets A and B are connected with the positive electrode end of an electrolysis compartment by cables, and are also connected with a first fuse by cables; the other end of the first fuse is connected with a first air switch, and the other end of the first air switch is connected with the positive electrode end of the electrolysis compartment; and the output ends of the negative busbars, connected with each other in series, of the rectifier cabinets A and B are connected with one end of a second fuse by cables, the other end of the second fuse is connected with a shunt, the other end of the shunt is connected with a second air switch, and the other end of the second air switch is connected with the grounding end of the electrolysis compartment. According to the method, the ground insulation of the electrolytic direct-current system can be mastered, grounding faults of the system can be found and treated in time, and multipoint grounding after power transmission can be prevented so as to avoid damage to equipment and human bodies.

Description

technical field [0001] The invention relates to the technical field of electrolysis DC system insulation in an electrolysis plant, in particular to an electrolysis DC system insulation withstand voltage test method. technical background [0002] After the electrolytic aluminum plant is put into production, it is subjected to strong DC current and high DC voltage during the entire production period. If the insulation of the electrolytic series is not good during the production process, there will be DC leakage, which will affect the current efficiency of electrolytic production and cause corrosion of plant buildings and equipment. , poses a threat to the safety of life, so in order to ensure the success of the electrolytic DC series power transmission and the safety of equipment and life before power transmission, it is necessary to check and measure each possible grounding point of the electrolytic series one by one. In practice, manual operation is required. It is very diff...
