Abstract
The invention relates to a method using trimethyl azide silane as an evaporative cooling medium of a generator stator, which is characterized by comprising: filling the trimethyl azide silane into a closed loop consisting of a hollow copper conductor of a generate stator winding and a condensation heat exchanger, or placing the generator stator into a sealed shell, soaking the trimethyl azide silane into the stator winding, and vacuumizing to 20 to 25kPa for use. The method overcomes the unsafe factors such as blockage, leakage and the like of internal water cooling modes, can reduce insulating grade, and is favorable for heat exchange. The working medium is obtained by the reaction of trimethyl chlorosilane and sodium azide in hexamethyl phosphorous acid triamide, and has simple production process and better economical efficiency than the prior environment-friendly cooling medium.
Description
Technical field
The present invention relates to a kind of cooling work medium, specifically, relate to a kind of inner transpiration-cooled environment-friendly type evaporative cooling working media of the hollow copper conductor of heavy-duty generator stator that is applicable to.
Background technology
The major measure that improves the generator single-machine capacity is to increase specific electric load, just can increase line bar copper damage simultaneously but increase specific electric load, and the temperature of coil will increase, and must adopt and strengthen cooling technology, to improve specific heat load.Along with the raising of generator single-machine capacity, the problem of stator cooling is outstanding day by day, and the types of cooling such as traditional air cooling, hydrogen-cooled, water-cooled and oil cooling are difficult to obtain effect preferably, and evaporative cooling becomes the main direction of studying of present stator cooling technology gradually.The coolant that evaporation cooling technique adopted belongs to fluorine Lyons series products, because contained Cl element has destruction to the ozone layer of atmosphere in fluorine Lyons, so F11, F12, F13 etc. are used in restriction at present, need select environment-friendly type cooling working medium for use.The environment-friendly type cooling working medium of using at present mainly contains Vertrel
Series, ASAHIKLIN is serial and perfluor tertiary amine series etc., and price is all relatively more expensive, makes the economy of evaporation cooling technique descend, and has influenced the The Application of Technology prospect.
The coolant that evaporative cooling adopted, must possess primary conditions such as chemical stability is good, nontoxic, non-corrosiveness, no explosion hazard, physicochemical properties such as its liquid insulation property, boiling point, surface tension, evaporation latent heat and viscosity also must satisfy certain requirement simultaneously, in addition, ozone layer destroying potential value (ODP) is zero.
Summary of the invention
The object of the present invention is to provide the method for a kind of using trimethyl azide silane, carry out evaporative cooling to be applicable to the hollow copper conductor of heavy-duty generator stator inside as evaporative cooling medium of generator stator.
For achieving the above object, using trimethyl azide silane provided by the invention is as the method for evaporative cooling medium of generator stator, be with the trimethyl azide silane filling in the closed-loop path that the hollow copper conductor of generator unit stator winding and condensing heat exchanger constitute, be evacuated to 20kPa～25kPa and use; Or
Generator unit stator is placed seal casinghousing,, be evacuated to 20kPa～25kPa and use with trimethyl azide silane submergence stator winding.
Effect of the present invention:
Overcome the unsafe factors such as stifled, leakage of internal water cooling mode, can reduce the class of insulation, heat exchanging is favourable.This working medium is reacted in hexamethyl tricresyl phosphite acid amides by trim,ethylchlorosilane and sodium azide and is got, production technology is simple, has only the market price of sodium azide higher in the raw material, about 60,000 yuan/ton, thereby the market price of this working medium can be very not high, and is better than the economy of existing environment-friendly type cooling medium.
Embodiment
The present invention is as the evaporative cooling working media of generator unit stator, and its Chinese name is called trimethyl azide silane, is called azidotrimethylsilane or trimethyl silyl triazo-compound again; Its English name is zidotrimethyl-Silane, azidotrimethyl-silane, zidotrimethylsilane, Trimethylsilyl azide or Trimethylsilylazide; Molecular formula is C
3H
9N
3Si; Structural formula is (Me)
3SiN
3Molecular weight is 115.21; The intermediate that the non-anti-avian influenza medicine of current main application is synthetic is not seen the report that has used as refrigerant.
In use, the trimethyl azide silane filling in the closed-loop path of hollow copper conductor of generator unit stator winding and condensing heat exchanger formation, is evacuated to 20kPa～25kPa and uses.Perhaps, generator unit stator places seal casinghousing, with working media submergence stator winding of the present invention, is evacuated to 20kPa～25kPa and uses.
The working media that the present invention adopts, its chemical property is stable, is heated to 590 ℃ and does not still decompose in gas phase, and this is because of the free 3d track of Si atom, and easy and N atom forms p, and π-d π joins key, so different in kind is in general organic azide.
The working media normal temperature and pressure that the present invention adopts is colourless liquid down, fusing point-95 ℃, 95 ℃ of boiling points (96kPa), 52-53 ℃ (23.3kPa), relative density 0.87 (20/4 ℃), index of refraction 1.4140 (20 ℃).Its boiling point under 23.3kPa, more approaching with the target temperature of the sub-stator cooling of generating.
The liquid insulation property of working media of the present invention are good, work as with the ordinary silicon oil phase, and dielectric constant is about 2.5～2.9.
The ODP of the working media that the present invention adopts is zero.
The working media that the present invention adopts is not put into the versions of being announced by national security production supervision management board and relevant department in 2002 " Hazardous Chemical Substances register ", does not belong to inflammable and explosive chemicals.
