Description
Technical field
The utility model is related to transformer equipment field, more particularly to a kind of transformer inflation storage dry-run protection system and
Transformer including the system.
Background technology
Transformer is the most important primary equipment of transformer station.Inside transformer safe operating life mainly depends on insulating materials
Mechanical strength and electrical strength.For in this sense, the good and bad of the insulating materials situation of transformer is determined and influenceed whole
The power supply reliability of individual transformer station.Storage is filled with nitrogen by injection transformer oil or fuel tank during traditional transformer non-installation and operation
The protective gas such as gas preserve, in theory under no fuel tank leak case, it is ensured that and transformation will not be influenceed by outside moisture,
Keep dry state.But substantial amounts of practice display, many transformers are in this protection storage method, because Oiltank structure, weather
Multiaspect factor, the inside transformers such as change, transport transfer are still made moist.This builds delivery to transformer station and produces huge shadow on time
Ring, or even many transformers have made moist and unknown by the people, finally result in transformer short-circuit accident.Especially domestic power network is built at present
It is transformation using how to be further ensured that in fuel tank the gas that do not make moist on the basis of Conventional pneumatic mode if extra-high voltage transformer
This great last one of safeguard procedures of electric power primary equipment setting of device, its meaning are very great.
Molecular sieve is the silicate or alumino-silicate of crystalline state, passes through oxygen bridge key phase by silicon-oxy tetrahedron or aluminum-oxygen tetrahedron
Even form duct and the cavity system of molecular dimension size (being usually 0.3~2.0nm).Molecular sieve is powdered crystal, is had
Metallic luster, hardness are 3~5, and relative density is 2~2.8, and natural zeolite has color, and synthetic zeolite is white, not soluble in water,
Heat endurance and acid resistance are with SiO2/Al2O3The increase of ratio of components and improve.Molecular sieve has very big specific surface area, up to 300
~1000m2/ g, interior brilliant apparent height polarization is a kind of high-efficiency adsorbent, and a kind of solid acid, and surface has very high sour dense
Degree and acid strength, the catalytic reaction of carbonium ion type can be caused.When other ions are carried out in the metal ion and solution in composition
During exchange, adjustable aperture, change its adsorption property and catalytic property, so as to which the molecular sieve catalyst of different performance be made.By
In metal ion and the water of compound state relatively low containing electricity price and that ionic radius is larger, hydrone continuously loses after the heating,
But crystal framework structure is constant, many size identical cavitys are formd, cavity has many diameter identical micropores to be connected again, this
Slightly small hole diameter is uniform, can be the inside of the Molecular Adsorption smaller than channel diameter to hole, and handle is than hole
The big molecular repulsion in road outside, thus can be the different molecule of shape diameter, the different molecule of polarity degree, and boiling point is different
Molecule, the different molecule of degree of saturation separates, that is, has the function that " to sieve " molecule, therefore referred to as molecular sieve.Molecular sieve
Absorption to water is physical absorption first, and the hydrone in molecular sieve interior surface air by layered adsorption and can liquefy,
Liquid water loading and molecular sieve inner surface, it can so reduce the high surface energy of bigger serface inside molecular sieve.
The drying system of transformer at present, it is the respiratory organ structure of the conservator connection above transformer.Inside respirator
Hygroscopic material silica gel particle prevents the moisture in air from entering transformer body oil.And the overanxious of this contact can not ensure to contain
Water air and body oil are kept completely separate, and actually simply play a slight retarding action.And it is exactly that the structure is body
With unique open channel in the external world, it also turns into the main path that body makes moist, and the silica gel particularly inside dehydrating breather is lost
After function, substantial amounts of moisture is entered in transformer body by this respiratory organ structure, so that transformer oil makes moist.
