1. An electrical isolation apparatus, comprising:
a primary stage configured to connect to a first signal device, wherein the primary stage comprises a first reference circuit and a first transmission circuit; and
a secondary stage configured to connect to a second signal device, wherein the secondary stage comprises a second transmission circuit and a second reference circuit, wherein
the first reference circuit, the first transmission circuit, the second transmission circuit, and the second reference circuit are not in contact with each other, and are sequentially disposed in parallel to a first plane, and there is a spacing between a projection of the first reference circuit on the first plane and a projection of the second reference circuit on the first plane;
the first transmission circuit comprises a first part and a second part; wherein
a projection of the first part on the first plane overlaps with a projection of a first region of the first reference circuit on the first plane, and a projection of the second part on the first plane overlaps with a projection of a second region of the second reference circuit on the first plane; and
the second transmission circuit comprises a third part and a fourth part; wherein
a projection of the third part on the first plane overlaps with a projection of a third region of the second reference circuit on the first plane, and a projection of the fourth part on the first plane overlaps with a projection of a fourth region of the first reference circuit on the first plane.
