Abstract
A gas discharge tube (GDT) can include first and second electrodes each including an edge and an inward facing surface, such that the inward facing surfaces face each other. The GDT can further include a sealing portion implemented to join the edge portions of the first and second electrodes to form a chamber between the inward facing surfaces of the first and second electrodes. The GDT can further include an electrically insulating portion implemented to provide a surface that covers a portion of the inward facing surface of each of at least one of the first and second electrodes such that a leakage path between the first and second electrodes includes a path on the surface of the electrically insulating portion.
Claims20
A gas discharge tube (GDT) comprising:
- first and second electrodes each including an edge and an inward facing surface, such that the inward facing surfaces face each other;
- a sealing portion implemented to join the edge portions of the first and second electrodes to form a chamber between the inward facing surfaces of the first and second electrodes;
- and
- an electrically insulating portion implemented to provide a surface that covers a portion of the inward facing surface of each of at least one of the first and second electrodes such that a leakage path between the first and second electrodes includes a path on the surface of the electrically insulating portion.
A circuit protection device comprising:
- a gas discharge tube (GDT) including first and second electrodes each having an edge and an inward facing surface, such that the inward facing surfaces face each other, the GDT further including a sealing portion implemented to join the edge portions of the first and second electrodes to form a chamber between the inward facing surfaces of the first and second electrodes, the GDT further including an electrically insulating portion implemented to provide a surface that covers a portion of the inward facing surface of each of at least one of the first and second electrodes such that a leakage path between the first and second electrodes includes a path on the surface of the electrically insulating portion;
- and
- a first clamping device electrically connected to the first electrode of the GDT.
