State the insulation tube body setting of gas discharge tube body.
Further technical solution is：The gas discharge tube body includes insulation tube body, is welded electrode using solder
The both ends of the insulation tube body are connected to, are sealed insulation tube body by electrode, pin is connect with the electrode respectively, the gas
Electric discharge tube body is fixedly connected by the pin with the pedestal.
Further technical solution is：The fuse is wound in the periphery of the insulation tube body.
Further technical solution is：Upper half setting of the fuse portion close to the insulation tube body.
Further technical solution is：Lower half setting of the fuse portion close to the insulation tube body.
Further technical solution is：It is provided with shell on the outside of the gas discharge tube body and fuse, it is described
Shell is fixedly connected with the pedestal, and using there is fillable particulate matter to be filled between the pedestal and the shell.
