Abstract
A discharge tube includes a cylinder having first and second end planes, first and second discharge electrodes coupled to the respective first and second end planes, the first and second discharge electrodes having respective upper and lower discharge planes forming therebetween a discharge gap, and one or more discharge trigger wires disposed in a portion of the cylinder that encompasses the discharge gap.
Claims10
A discharge tube comprising:
- a cylinder having first and second end planes;
- first and second discharge electrodes coupled to the respective first and second end planes, the first and second discharge electrodes having respective upper and lower discharge planes forming therebetween a discharge gap;
- and
- one or more discharge trigger wires disposed in a portion of the cylinder that encompasses the discharge gap;
- wherein the discharge tube is situated no more than 2 mm from at least one of a coil and a transformer;
- wherein the one or more discharge trigger wires are uniformly situated on the first plane that perpendicularly intersects with the axial direction of the cylinder;
- and
- wherein all discharge trigger wires disposed in the cylinder are oriented in a direction perpendicularly intersects the axial direction of the cylinder.
