Beneficial effects of the present invention：
The present invention is directed to existing market demand, and the μ s impulse current waveforms of direct lightning strike 10/350 can be met after optimization design
50KA；In tubular body structure design, the electrode for having influence on machining area optimizes design, add ring electrode and
Pin electrode, ring electrode are designed using cambered surface, on the premise of homogeneous tube outside dimension and discharging gap are constant, are effectively increased discharge face
Product, increase the powder amount of electronic powder.
Pin electrode of the present invention corresponds to the radian design of ring electrode, ensures the uniformity of discharging gap, improves nominal DC electricity
The stability of pressure；Ring electrode and pin electrode use Tungsten-copper Composites, eliminate ceramic gas discharge tube during by high current,
The deformation caused by electrode generates heat.The stability of product is improved, is increased the service life.
In the present invention, ring electrode and pin electrode are tungsten copper material, ordinary telegram extremely oxygen-free copper material matter, in the process of vacuum brazing
In, because of the difference of the coefficient of expansion between material, wetting can be caused bad.When ring electrode and pin electrode design, with
Flat electrodes weld using oozing layer, oxygenless copper material thick welding about 1mm on ring electrode and pin electrode, eliminate ring electrode and
The risk that pin electrode comes off in use.
Other features and advantages of the present invention will be described in detail in subsequent specific embodiment part.
