GAS-FILLED DISCHARGER AND METHOD FOR ITS MANUFACTURING Russian patent published in 2013 - IPC H01J17/02 H01T1/00 

FIELD: electricity.

SUBSTANCE: discharger comprises a metal body in the form of a hollow cylinder with a transverse partition, an insulator in the form of a hollow truncated cone and two electrodes. The first electrode is arranged on the partition, and the second one - on the screen on the smaller base of the insulator. Inside the insulator there is a lead of the second electrode, connected with the second lead arranged in the insulator in the upper part of the cylinder volume by means of conductors stretching via holes in the partition and fixed on the screen in the lower volume of the cylinder and on the transition contact in the upper volume of the cylinder. Connection of the cylinder edge with the insulator in the lower part of the cylinder volume is arranged via a collar by a covering soldered joint from a high temperature solder, and in the upper part of the cylinder volume - via a collar with a covering soldered joint from a high temperature solder and a transition ring in contact with the cylinder. Connections of the lead of the second electrode and the second lead with end surfaces of smaller bases of insulators and screens are made by the second solder with melting temperature below the melting temperature of the high-temperature alloy. Connections of the partition to the cylinder, conductors to the screen and the transition contact are made by the third solder with the melting temperature not higher than the melting temperature of the second solder. External edges of the collar and the cylinder in the lower part of the volume, the collar and the transition ring, the transition ring and the cylinder in the upper part of the volume are connected to each other by means of welding.

EFFECT: higher reliability and tightness.
