Fig. 2 is structural representation of the thermal resistance in electric insulation heat transfer film surface " Z " type distribution.
Specific embodiment
In order that those skilled in the art becomes apparent from understanding that the understands the present invention, in conjunction with specific embodiment and attached
Figure, the present invention is described in detail.
As shown in figure 1, gas discharge tube electrode of the invention is mainly used in ceramic gas discharge tube.Common ceramic gas
Body discharge tube mainly includes metal electrode 5, earthenware 6, electronic powder 7, lead 1, lead 2.The present invention is to common ceramic gas
Discharge tube is transformed, and is first to coat one layer of electric insulation heat transfer film (not shown) on the surface of metal electrode 5.It is described thin
Film it is main by 2~6 parts of titanium dioxide, 3~7 parts of alundum (Al2O3), 1~5 part of carborundum, 9.5~15 parts of kaolin, propyl alcohol 15~
25 parts, 20~30 parts of polymethyl methacrylate, 24~35 parts of polyarylene sulfide resin, 0.5~2 part of trimethoxy silane system
Into.In order that metal electrode 5 has more preferable radiating effect, outside of the metal electrode 5 just to electronic powder 7 is sequentially put down in the present invention
Row is arranged with multiple radiating fins 5 ', and the radiating fin 5 ' is integrally formed with the electrode 5 by metal material, middle radiating fin 5 '
Long, the radiating fin 5 ' of both sides is short.Thus, born for a long time or during continually overcurrent when ceramic gas discharge tube, gas discharge
Two metal electrodes 5 of pipe will quickly be derived heat by radiating fin 5 ', so as to prevent gas-discharge tube from overheating.
For the technical problem that the ceramic gas discharge tube response time is long, the present invention it is above-mentioned it is improved on the basis of to ceramics
Gas-discharge tube has made further improvement.Be first in electric insulation heat transfer film placement thermal resistance 4, the thermal resistance 4 with
One glass gas-discharge pipe 3 is in parallel with the ceramic gas discharge tube again after connecting.4 ' is drawing for two thermal resistances 4 of connection
Line.When ceramic gas discharge tube two ends produce high pressure, the conducting of the quick response of glass gas-discharge pipe 3 generally only needs several nanoseconds,
Electric current is heated by thermal resistance 4 to the electrode 5 of ceramic gas discharge tube so that the electronic powder 7 in ceramic gas discharge tube more holds
Easy release electronics, gas motion in ceramic gas discharge tube is more violent, be more easy to puncture, so as to greatly shorten ceramic gas
Response time.Using this scheme, the response time of ceramic gas discharge tube can be made by hundreds of original nanoseconds to several milliseconds
It was reduced to for tens nanoseconds.In order to increase the resistance value of thermal resistance 4, can be in by heating wire bending winding by the thermal resistance 4 first
Helix, then " Z " type is distributed in the electric insulation heat transfer film surface again, as shown in Figure 2.
Due to the electric insulation heat transfer film on the surface of metal electrode 5 need to meet electrical insulating property is good, heat conduction efficiency is high and
Resistant to elevated temperatures feature, therefore formula of the present invention also to the heat transfer film that is electrically insulated is studied, specific embodiment is as follows.
