Method for manufacturing laminated busbar and laminated busbar manufactured by the method

Abstract

The invention discloses a method for manufacturing a laminated busbar, which comprises the following steps: machining conducting panels and insulating panels of each layer; spraying insulating powder on the surfaces of the conducting panels of each layer; and alternately stacking the conducting panels coated with the insulating powder and the insulating panels in a laminating die, and then laminating the conducting panels and the insulating panels into a whole by a laminating machine. Through spraying technology, the method makes insulativity of the conducting panels of each layer more easily realized, can realize multidimensional insulativity of more complex parts and has the advantages of low cost of insulating treatment, low energy consumption, few laminating times and high production efficiency. In addition, by adopting a laminating method with the laminating die, the method effectively reduces the volume of the laminated busbar and has high safety. The invention also provides the laminated busbar manufactured by the method.

Description

technical field [0001] The invention relates to a method for manufacturing a busbar and a busbar manufactured by the method, in particular to a method for manufacturing a laminated busbar applicable to large servers, communication cabinets, electrical control cabinets, etc., and the laminated busbar manufactured by the method. Background technique [0002] Most electrical products, such as: large servers, communication cabinets, electrical control cabinets, etc., use laminated busbar technology to reduce parasitic inductance and obtain better electrical performance. At present, the commonly used laminated busbars are based on plastic sheets for plastic insulation. For the production method, please refer to Figure 1a ~ Figure 1e , taking the lamination of two layers of conductive plates as an example, each layer of conductive plates is firstly insulated and molded and bent, and then each layer is formed by laminating each layer with a double-sided adhesive insulating sheet. ...

AI Technical Summary

Problems solved by technology

However, since the currently commonly used hot-melt insulating sheets are purchased through imports, the price is relatively high, so the material cost and processing cost of this process are relatively high

[0005] (3) Lamination cost is high: this process requires more lamination times, usually the total number of laminations required is: N+1, (wherein, N is the number of layers of conductive plates), so the corresponding needs are more Multiple and more complex lamination dies
