This paper presents conductive polymer molecular materials with insulating powder, mixed into the deployment of surge suppressors for low capacitance of paste, while the component design concept is based on the field of passive components, manufacturing process to make the basic theory to design the protective components, the main use of the existing ceramic substrate for the component body structure design, screen design in the body through the structure of the gap at the top of the printing layer of a different conductors, and then to learning to know the printing process technologies approach the low capacitance of the surge suppressor paste cover the gap in the two conductors, and by the resistance of plastic burning process technology, the temperature of sintering parts made of electrostatic protection element, and this protection through the external ESD components in bombardment tests, measurement of capacitance electrostatic discharge after bombardment, Trigger voltage and leakage current data, and the volume measured by the results of future discussion of the layout of this different style of work in the same area, different clearance, solid content and temperature than the next, for the attainment of performance components, a low capacitance ESD protection devices with low breakdown voltage requirements and to chip-based protection devices can be designed to integrate with the advanced Integrated Circuits or used independent of the electrostatic protection element in the system.

Its working principle is introduced here: when a gas or powder starts a flame or explosion, the ultraviolet sensor will acquire the signal and sent it to the controller to produce the trigger voltage, and then the explosive suppressor will release a great number of gas promptly spraying dry powder extinguishing agents, which thereby form extinguishing agent smoke and effectively extinguish explosion flame. It is rapid and of strong antiinterference ability, high reliability and can be fixed easily. It is capable of effectively suppressing natural gas explosion in the simulative gas explosion test. It can be applied in CNG stations or other site where has explosive and combustible gas whereby to enhance the overall accident control ability.
