Embodiment 1
[0026] see figure 1 , a lightning protection transformer provided in this embodiment is installed on the signal transmission channel of the indoor equipment and outdoor equipment of the railway track, including: a primary coil 1, a secondary coil 2 and an ED core 3, wherein,
[0027] Both the primary coil 1 and the secondary coil 2 are wound in the center of the ED-type iron core 3; the primary coil 1 is wound with an inner anti-lightning induction shielding layer for one turn before winding, and then wound A circle of outer anti-lightning induction shielding layer; the inner anti-lightning induction shielding layer and the outer anti-lightning induction shielding layer are electrically connected to the ED type iron core 3 and grounded.
[0028] It can be seen from the above technical solution that the lightning protection transformer provided by the present invention adopts an ED-type iron core, the primary coil and the secondary coil are both wound in the center of the ED-ty...
Embodiment 2
[0030] A lightning protection transformer provided in this embodiment is installed on the signal transmission channel of indoor equipment and outdoor equipment on a railway track, and includes: a primary coil 1, a secondary coil 2 and an ED core 3, wherein,
[0031] Both the primary coil 1 and the secondary coil 2 are wound in the center of the ED-type iron core 3; the primary coil 1 is wound with an inner anti-lightning induction shielding layer for one turn before winding, and then wound A circle of outer anti-lightning induction shielding layer; the inner anti-lightning induction shielding layer and the outer anti-lightning induction shielding layer are electrically connected to the ED type iron core 3 and grounded.
[0032] Preferably, a skeleton is arranged in the center of the ED-type iron core, and the secondary coil and the primary coil are wound on the skeleton successively; For the lightning induction shielding layer, after the winding is completed, an outer anti-lig...
Embodiment 3
[0037] A lightning protection transformer provided in this embodiment is installed on the signal transmission channel of indoor equipment and outdoor equipment on a railway track, and includes: a primary coil 1, a secondary coil 2 and an ED core 3, wherein,
[0038] Both the primary coil 1 and the secondary coil 2 are wound in the center of the ED-type iron core 3; the primary coil 1 is wound with an inner anti-lightning induction shielding layer for one turn before winding, and then wound for one turn after the winding is completed. The outer anti-lightning induction shielding layer; the inner anti-lightning induction shielding layer and the outer anti-lightning induction shielding layer are electrically connected to the ED type iron core 3 and grounded.
[0039] Preferably, a skeleton is arranged in the center of the ED-type iron core, and the secondary coil and the primary coil are wound on the skeleton successively; For the lightning induction shielding layer, after the wi...
