Description
Technical field
The present invention relates to a kind of production methods of full surface damp proof insulation dry-type air-core reactor.
Background technology
Dry-type air-core reactor (hereinafter referred to as reactor) is a kind of for limiting short-circuit electricity inside power system transformer substation
The important equipment of the occasion of stream, reactive-load compensation and phase shift etc..Running uses reactor outdoors for a long time, face coat and surface layer
Phenomena such as material easily occurs aging, makes moist, becomes fragile or even fall off, removes.The manufacture craft existing defects of this and reactor cease
Correlation, in the production process, using traditional manufacturing technique, the aluminum conductor layer of each circle is by epoxy resin fiberglass glue for reactor
Adherency package is connect, meanwhile, each aluminum conductor has also wrapped up polyester film processing.Then dry using successively winding, package, solidification
It is dry to be finally made reactor arrangement product.Since epoxy resin layer and aluminum conductor layer are directly glued, with the increasing of pot life
It the phenomenon that adding, being susceptible to ageing hardening or even degumming disengaging, will directly be deposited with aluminum conductor layer in epoxy skins in this way
In certain gap.And epoxy skins pass through specially treated, in waterproof and dampproof aspect of performance there are certain deficiency,
Moisture vapour molecule readily penetrates through epoxy skins and penetrates into aluminum conductor inner layer, and under electric field action, equipment is in for a long time
Under electricity, heat, the use environment of tide, the polyester film overheat for easily causing aluminum conductor surface layer makes moist and hydrolyzes fusing, such knot
Fruit is that aluminum conductor is caused directly under the barrier of not polyester film, directly to contact with each other between aluminum conductor, is caused short between wire turn
Road, equipment local pyrexia, epoxy skins melted by heat eventually lead to equipment burnout.
During existing reactor is manufactured, without full surface coat damp proof insulation coating the step of, each layer around
Group has soaked epoxy resin, integral with regard to direct-assembling, because after overall package, then carry out surface to coat that being extremely difficult
, after causing product export to put into operation, there are some potential safety problemss.
Invention content
The technical problem to be solved by the present invention is to：There is provided a kind of can form the dry of moisture-proof insulation layer on the full surface of reactor
The production method of formula air-core reactor effectively improves the service life of reactor.
The solution that the present invention solves its technical problem is：
A kind of production method of full surface damp proof insulation dry-type air-core reactor, includes the following steps：
1) by two-terminal be flexible coupling, conducting wire welds together, then carry out coiling, coil be made；
2) coil and pedestal, column piece, upper core, lower core and cover board are assembled together；
3) coil of assembly together is poured into a mould with pedestal, column piece, upper core, lower core and cover board；
4) reactor assemblies after cast are subjected to damp proof insulation coating；
5) by the reactor assemblies assembled formation after coating；
6) test before manufacture.
Wherein, the painting method is spraying or dip-coating.
Further, the damp proof insulation coating formula that the damp proof insulation spraying uses is composed of the following components：107 silicon rubbers
Glue, gas-phase silica, calcium carbonate, dimethicone, platinum catalyst, aluminium oxide, magnesia, mill base, organic solvent.
The beneficial effects of the invention are as follows：Damp proof insulation painting is carried out to the reactor assemblies after cast by successively coating processes
It covers, avoids the paint waste and inconvenient that reactor entirety coated is come, while can be good at avoiding coating sagging
The phenomenon that.In addition full surface damp proof insulation reactor production process can ensure that need not be sprayed in power failure after equipment manufacture puts into operation
It applies, has ensured the safe operation of equipment.
