Under such conditions, the steady flow control cabinet and unit power distribution cabinet that have been in the strong magnetic field of the DC busbar for a long time will malfunction due to the interference of the strong magnetic field, and even some equipment will generate eddy currents and cause heat and burnout. It is difficult to ensure their stability and reliability. running
Once this happens, it will cause huge economic losses to users

Embodiment Construction
[0010] As shown in the figure, the configuration structure of the power distribution control equipment of the rectifier unit in the rectification station of the electrolytic aluminum plant of the present invention includes a rectifier transformer compartment 4 and a rectifier room 5, and a steady current control cabinet 1 and unit power distribution are arranged in the channel of the rectifier transformer compartment 4 The cabinet 2 is far away from the large DC bus 6, which solves the interference of the strong magnetic field of the DC large bus 6 on the steady current control cabinet 1 and the power distribution cabinet 2 of the unit. A fire door 3 is provided between the rectifier transformer interval 4 and the rectifier room 5.

The invention relates to a configuration structure for power distribution control equipment and especially to a configuration structure for power distribution control equipment of a rectifier unit in a rectifying station of an aluminum electrolysis plant, wherein, a stabilized current control cabinet and a unit power distribution cabinet are located in the rectifying station with strong direct current outputting current. The configuration structure comprises a rectifier transformer compartment and a rectifier chamber, and the stabilized current control cabinet and the unit power distribution cabinet are arranged in a channel of the rectifier transformer compartment. The invention has the following advantages: application of the configuration structure enables interference of a strong magnetic field of a big direct current bus to the stabilized current control cabinet and the unit power distribution cabinet to be avoided, thereby ensuring reliable operation of the stabilized current control cabinet and the unit power distribution cabinet and improving reliability of power supply of the rectifying station; meanwhile, a fire door is provided between the rectifier transformer compartment and the rectifier chamber, which facilitates debugging, examining and repairing of the equipment.
Description
technical field [0001] The invention relates to a configuration structure of power distribution control equipment, in particular to a configuration structure of power distribution control equipment of a rectifier unit in a rectification station of an electrolytic aluminum plant where a steady current control cabinet and a unit power distribution cabinet are located in a rectification station for strong direct current output. Background technique [0002] In recent years, with the rapid development of aluminum electrolytic cell manufacturing technology, the direct current of electrolytic cell series has reached more than 400kA. In the past, the rectifier cabinet was installed as close to the rectifier transformer as possible, while the steady current control cabinet and unit power distribution cabinet were often chosen to be installed on the opposite side of the rectifier cabinet and close to the DC bus side in consideration of operational safety. Now, with the increase of th...
