Detailed description of the invention
As shown in figures 1 to 6, present embodiment discloses a kind of ansi standard electric energy meter, it includes shell 1, base 2, support 3, inner bag 4, current transformer 5, relay 6 and PCBA7, shell 1, base 2, support 3 and inner bag 4 are connected as a single entity and form the shell of this electric energy meter, and current transformer 5, relay 6 and PCBA7 are connected as a single entity and are fixed in shell.
Its repeat circuit 6 includes that relay body 61 and current terminal 62, current terminal 62 are the template current terminal that three sections of square type sections are constituted, and the width of its two ends rectangular section does not waits and is all higher than the width of interlude.Current transformer 5 is column type, its axial centre is provided with rectangular through slot 51, the width of rectangular through slot 51 is between the width of current terminal 62 two ends rectangular section, the thickness of rectangular through slot 51 is more than the current terminal 62 external diameter of a circle of interlude, width less than current terminal 62 two ends, and the interlude of current terminal 62 can rotate in rectangular through slot 51.
The main body of base 2 is annulus 21, is evenly equipped with three boss 22 outside annulus 21, is provided with attachment structure 23 and public hook 24 inside annulus 21, and annulus 21 bottom is provided with leg 25.
The main body of support 3 is cylinder jacket 31, and the inwall of rack body is provided with female hook 32, and the upper end of rack body is provided with fixed mount 33, and fixed mount 33 is provided with clamp 34.
Inner bag 4 is cylinder type, and the gallbladder wall of inner bag 4 is provided with the draw-in groove 41 being matched with clamp 34, and the opening of inner bag is buckled in the upper end of rack body.
Shell 1 is column type, and its inwall is provided with corresponding groove 11 at boss 22 outside corresponding base 2.
