METAL ENCAPSULATION FOR SWITCH GEAR, AND METHOD FOR MANUFACTURING THE SAME

摘要

THE PRESENT INVENTION RELATES TO A METAL ENCAPSULATION FOR SWITCH GEARS OR SWITCH GEAR ARRANGEMENTS, ESPECIALLY FOR MEDIUM VOLTAGE SWITCHGEAR IN WHICH THE METAL BLANK IS CUT AND JOINED TOGETHER. THE METAL BLANK (1) OR DIFFERENT METAL BLANKS (10, 20) TO BE JOINED TOGETHER HAVE THE SHAPE OF A DEFOLDED BOX, IN WHICH PERFORATIONS (2) ARE IMPLEMENTED ALONG PREDETERMINED FOLDING LINES. THE METAL BLANKS ARE FOLDED TO A 3-DIMENSIONAL ENCAPSULATION AND THE METAL BLANK OR BLANKS ARE FOLDED TO A GASTIGHTLY JOINED METAL ENCAPSULATION. THERE IS ALSO DISCLOSED A METHOD FOR MANUFACTURING METAL ENCAPSULATION FOR SWITCH GEARS OR SWITCH GEAR ARRANGEMENTS. (FIG. 1)
