In order to improve the ageing resistance of discharge protector, also allowing for hot compression molding, described lagging material is methyl vinyl silicone rubber or thermoplastic engineering plastic or Thermoset engineering plastics simultaneously.
Described discharging gap is sealed gas discharge tube, and structure is at columnar ceramic package two ends fixed metal electrode, the end plane metal of ceramic package, then with electrode welding, form a cylinder sealed, be wherein filled with neon/argon gas, be provided with irradiation electrode in ceramic inner walls.It is so designed that, further increases the sealing of the discharging gap of discharge protector, improve the dispersibility of disruptive discharge voltage.
For the ease of being connected with described discharging gap, corresponding connection electrode is set in two metal electrode outer faces of described discharging gap, described connect electrode respectively with described discharging gap two metal electrode by weld or conductive adhesive and form reliable electrical connection.
Described discharging gap, connect electrode surface and scribble one layer of silane coupler, ensureing described discharging gap, connect electrode with described lagging material fully bonding.
In order to connect inside and outside simplicity, arranging a screw at the described other end connecting electrode, one end of described terminal screw is connected with described connection electrode by the screw thread of screw, and the other end is that external cabling is used.
Described end cap is matched with described overcoat two ends, and further, described end cap central authorities open a circular hole, in order to described terminal screw is connected with described connection electrode.
