(3) beneficial effect
Compared with prior art, a kind of gas-filling cabinet pole with heat sinking function provided by the present invention goes out in vacuum
It is provided with silastic-layer, insulating cylinder and epoxy resin around arc chamber to be sealed, when generation electric arc in vacuum interrupter sends
During amount of heat, epoxy resin will produce a certain degree of deformation after original temperature is recovered, and spring can make up just by
The deformation that " expanding with heat and contract with cold " is brought so that epoxy resin is tightly fitted all the time with vacuum interrupter, is effectively improved and is gone out in vacuum
The sealing before and after electric arc in pole is produced in arc chamber；Additionally, can be by generation in inner shell by the way of water circulation
Heat is taken away, it is to avoid enclosure interior temperature is raised, while external heat can also be blocked conduct to pole, so as to effectively be lifted
The heat dispersion of pole, it is ensured that the connecting-disconnecting function of vacuum interrupter.
