A main power line lead-out structure of an energy storage sodium-sulfur battery module

Abstract

The invention discloses a main power supply wire extraction structure of an energy-storage sodium-sulfur battery module. The main power supply wire extraction structure comprises a linear aluminum bar, a convex-concave button, a flexible conducting wire and an F-shaped aluminum bar which is formed by stamping an aluminum plate in one step and bending the aluminum plate on multiple positions, wherein the tail end of the F-shaped aluminum bar is also bent, and the extension end of all bending positions including the bending position on the tail end are respectively connected with lugs of sodium-sulfur batteries one by one; the first end of the linear aluminum bar is connected with the bending position on the tail end of the F-shaped aluminum bar, the second end of the linear aluminum bar penetrates through a heat preserving box to be led out of a heat preserving box body and is connected with a fuse through the flexible conducting wire; the second end of the linear aluminum bar penetrates through the convex-concave button and fixed on a shell of the heat preserving box body through the convex-concave button. By adopting the main power supply wire extraction structure, the safety passing of large current can be guaranteed, the influence of the hot expansion and cold shrinkage of the metal in a temperature variation process on the internal battery and external devices can be reduced, and the loss of the internal heat can be prevented to a certain extent.

Description

technical field [0001] The invention relates to a sodium-sulfur battery, in particular to a lead-out structure of a main power line of an energy storage sodium-sulfur battery module. Background technique [0002] Sodium-sulfur battery is a secondary battery with metallic sodium as the negative electrode, sulfur as the positive electrode, and ceramic tube as the electrolyte diaphragm. It is a type of very potential energy storage battery. At 300°C-350°C, there are a large amount of liquid elemental sodium and elemental sulfur inside the battery. If they are accidentally contacted, a high temperature close to 2000°C will be generated, which is quite dangerous in use. Therefore, a corresponding incubator is needed to protect the sodium-sulfur battery. [0003] Generally, the internal temperature of the sodium-sulfur battery module insulation box is above 300°C, while the external temperature of the box is close to room temperature. At the same time, due to the characteristics...
