Description
Technical field
The present invention relates to a kind of frostproofer, particularly relate to a kind of for the frostproofer in Temperature Measurement System for Transformer, be mainly applicable to more than 66kV power transformer tank temp measuring system.
Background technology
At present, the measuring method of measuring transformer oil temperature is, transformer-cabinet and the special hole of transformer thermometric are kept apart, all transformer oil is put in two containers, transformer oil in the special hole of thermometric does heat conduction and uses, meanwhile, this area generally believes in the special hole of thermometric to only have the filling transformer oil same with transformer-cabinet just can better complete heat conduction thermometric.
But in prior art, larger than transformer oil because of the proportion of water in the winter of cold, so after thermometer hole water inlet, water will sink to the bottom of thermometer hole.Because the northeast winter summer temperature difference is large, owing to expanding with heat and contract with cold, be very easy to the bursting by freezing causing thermometer, this running condition for monitoring transformer has a significant impact.
The kind of conventional frostproofer is a lot, calcium chloride (CaCl2) in picture inorganics, methyl alcohol (CH3OH) in organism, ethanol (C2H5OH, popular name alcohol), ethylene glycol (C2H4(OH) 2, popular name is sweet and pure), propylene glycol, glycerol (C3H5(OH) 3, popular name glycerine), granulated sugar common in lubricating oil and our daily life, honey etc., all can be used as the mother liquor of deicing fluid, add appropriate pure soft water (containing or on a small quantity containing calcium, the water of magnesium ion, as distilled water, unpolluted rainwater, snow-broth etc., the total hardness constituent concentration of its water quality is between 0-30ppm) after, deicing fluid in general sense can be become.But its frostproofer only has antifreezing effect, be deicing fluid in general sense, be unsuitable for Temperature Measurement System for Transformer.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, according to transformer oil, the density of water, heat conductivility, dielectric strength, zero pour, evaporation rate and life-time service temperature, provide a kind of for the frostproofer in Temperature Measurement System for Transformer.
Another object of the present invention is to provide the application of a kind of frostproofer in Temperature Measurement System for Transformer.
Frostproofer of the present invention adds filler mixed preparing by this based polysiloxane of methyl to form; Preparation mass percent is that this based polysiloxane of methyl accounts for 95.23%; Filler accounts for 4.77%.
The molecular formula of described this based polysiloxane of methyl is, C15H32O3Si4.
Described filler is silver powder.
Described silver powder is formulated by mass percentage by following raw materials according, zinc oxide 26.32%; Aluminum oxide 21.07%; Boron nitride 7.89%; Silicon carbide 13.15%; Aluminium powder 31.57%.
Advantageous effect of the present invention is as follows:
Frostproofer of the present invention is a kind of white body of paste, major ingredient is this based polysiloxane of methyl, the large twice of density ratio water, heat conductivility, than insulation innage three times, does not solidify at subzero 50 DEG C, does not gasify at 200 DEG C, thermal conductivity ratio transformer oil exceeds about 26 times, density is 2 times of water, and this body of paste pole is not volatile, and the probability that after application, transformer thermometer damages reduces greatly.Solve the problem of more than 66kV power transformer tank temp measuring system bursting by freezing in prior art.
Meanwhile, the performance of temperature of oil in transformer measuring system is improved; Guarantee the thermometer of temperature of oil in transformer measuring system within subzero 50 DEG C not by bursting by freezing; Enhance productivity, guarantee power network safety operation.
