With the development at a high speed of the social economy and science and technology, the whole power system put forward the higher and higher request to the electric energy of high quality, high dependability. Realize the distribution automation, electrification, intelligent of the power system progressively, In order to raise the power supply reliability of the whole distribution system, its social benefit and economic benefits are all very obvious. The task of this text is to monitor the density of killing the arc medium and insulation SF6 gas online in high pressure distribution switches, high pressure distribution equipment, high-power become person who give, high pressure cable, etc. Thus achieve the safe operation of power system and purpose with practical economy.
    The optic fiber sensor receives extensive application because of a series of unique technology superiority of it. Have studied SF6 of the nature and demonstrated importance of measuring the density of SF6 gas in this text, With the evolution and foundation of the current situation of optic fiber sensor and measurement of density of SF6 gas, Have analyzed some drawbacks that the existing density of SF6 gas measure technology and method, Point out their application limitation. This paper is by measuring the method indirectly, Transmit all signal through the optic fiber and monitor gas pressure and temperature, By utilizing relations gas pressure and temperature carry on mathematics method but produce density of gas finally. The method have rational design, structure simple, explosion-proof, able to bear corrode, merit of defending electromagnetism interfere etc, Suitable for the application in the abominable and dangerous environment.
    Have studied the characteristic of every main part including transmission characteristic of the optic fiber in the system of optic fiber temperature survey in this text; Have analyzed the characteristics of LED light source, photodetector, photocell and optic fiber coupling machine theoretically, According to experiment condition choose signal optic fiber, photocell detector, LED light source and coupling way of optic fiber rationally. And the principle of liquid temperature survey of optic fiber adopted to temperature survey is described, And have proved
    
    
    that the scheme is the most rational. Have designed the concrete drive circuit of LED light sources and the concrete circuits of preamplifier and subtracter, etc. Experiment course and result have been given, and went on the theory to analyze.
