Description

Frosting and dew prevention system from C-section current lead to power supply copper bar Technical Field The invention belongs to the technical field of power supply copper bar frosting prevention, and particularly relates to a frosting and condensation prevention system from a C-section current lead to a power supply copper bar. Background The current lead in the Tokamak device usually needs to operate at extremely low temperature (-200 ℃ below zero), so the temperature of the current lead is also very low, and the temperature of the section C of the current lead connected and conducted with the copper bar of the atmospheric side power supply is below-10 ℃ due to the heat conduction property of the copper material. The water exists in the air at the connecting place, and the water contacts the low-temperature current lead to generate frosting or condensation, so that the insulating property of the insulating layer wrapping the copper bars is reduced, and when the power supply copper bars work, 700-1000A current is required to pass through, and the short circuit among the copper bars is caused by serious reduction of the insulating property, so that the power supply is burnt, even explosion is generated, and the personal safety of operators is critical. Based on this, there is a need to design an anti-frosting system to solve the problem, and prevent frosting or condensation of the copper bars.
