Abstract
The invention discloses the online rapid plugging method for fiberglass of a kind of oil-filled transformer, it is characterized in that: after at the breakthrough of oil-filled transformer and being around carried out, first breakthrough is blocked with adhesive, then it is coated with fluid sealant at surface of pressure-sensitive adhesive, the metal case of charge valve it is provided with again on the outer shroud of fluid sealant, the most backward metal cap shell inner inflatable, makes the intrinsic pressure power of metal case more than oil-filled transformer internal pressure, i.e. completes closure.The method plugging effect of the present invention is good, substantially prolongs the useful life after transformator is repaired, it is ensured that the safety and economic operation of network system, and simple to operate, it is not necessary to power-off, drain the oil.
Description
Technical field
The present invention relates to the online rapid plugging method for fiberglass of a kind of oil-filled transformer, belong to transformator sealing and plugging field.
Background technology
Power transformer is as an important component part in electric power system, and its running status directly affects electric power system
Safety economy level.When leakage of oil occurs in transformator, the most then appearance is polluted, heavy then affect electric power netting safe running.Therefore, disappear
Except Leakage in Transformer oil phenomenon is safety in production and the important step carried out production strictly in line with rules and regulations.
At present, the method for blocking for transformer oil seepage glues reinforcement frequently with tin bar welding and adhesive.Tin bar welds
Connection causes transformer oil to produce the gas such as acetylene because temperature is too high during welding, the welding therefore power failure of having to is drained the oil, so that the party
Method workload is big and maintenance time is long, have impact on the stable operation of power system；Though adhesive glue reinforcement can online leak stopping, but by
There is certain oil pressure inside when transformator works, cause breakthrough to have the seepage of insulating oil in adhesive solidification process,
Bonding interface will have a strong impact on adhesive bond power simply by the presence of trace oil stain, and after leak stopping, after experience is not long-time, leak stopping point again can
The phenomenon of leakage of oil again occurs.
Summary of the invention
The present invention is for avoiding the weak point existing for above-mentioned prior art, it is provided that a kind of oil-filled transformer online
Rapid plugging method for fiberglass, it is intended to by fluid sealant and the dual function of metal case, improves plugging effect, after extending transformator reparation
Useful life.
The present invention solves technical problem, adopts the following technical scheme that
The online rapid plugging method for fiberglass of a kind of oil-filled transformer, it is characterised in that it comprises the steps:
Step 1, clean at the breakthrough of oil-filled transformer and around, and dry, expose the transformator outer wall gold of cleaning
Belong to body；
Step 2, immediately use adhesive block breakthrough；
Step 3, after adhesive is fully cured, the surface of adhesive be coated with last layer fluid sealant, make fluid sealant cover completely
Cover adhesive；
After step 4, glue to be sealed are fully cured, form sealant layer, the periphery of cleaning sealant layer；
Step 5, coat a circle adhesive in the periphery of sealant layer, then top is provided with the metal cap clamshell of charge valve
In the periphery of sealant layer, and it is bonded at adhesive, outside described metal case, applies pressure, until after metal case cements admittedly
Cancel pressure again；
Step 6, employing inflator to metal case inner inflatable, make the intrinsic pressure power of metal case more than oil immersion by charge valve
Formula inside transformer pressure, then pulls out inflator, closes charge valve, i.e. complete the online fast blockage of oil-filled transformer.
Preferably, described adhesive is the modified phenolic adhesive using SiC filler to fill.Described fluid sealant is rubber-type
Fluid sealant, has the character of high temperature high voltage resistant.Described charge valve is unidirectional charge valve.
Compared with the prior art, beneficial effects of the present invention is embodied in:
1, the online rapid plugging method for fiberglass of oil-filled transformer of the present invention, by fluid sealant and the dual work of metal case
With, improve plugging effect, and by applying pressure in metal case, make the diaphragm seal in metal case to consolidate for a long time,
Substantially prolongs the useful life after transformator is repaired, it is ensured that the safety and economic operation of network system, overcome existing tin bar
Welding and adhesive glue the deficiency that reinforcement exists.
2, the online rapid plugging method for fiberglass of oil-filled transformer of the present invention, it is not necessary to power-off, drain the oil, easy and simple to handle, operative employee
Tool and material are easy to get.

Labelling in figure: 1 transformator outer wall；2 breakthroughs；3 adhesive layers；4 sealant layers；5 metallic iron covers；6 charge valves.
Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is elaborated:
As depicted in figs. 1 and 2, the online rapid plugging method for fiberglass of the present embodiment oil-filled transformer, comprise the steps:
Step 1, clean at the breakthrough 2 of oil-filled transformer and around, and dry, expose the transformator outer wall 1 of cleaning
Metal body；Concrete mode is as follows:
Tentatively clean oil stain and the attachment filth of doubtful leakage on transformator outer wall with acetone, and dry with cleaning cloth,
Spraying white lime the most in this range, the point observing white lime variable color at first is breakthrough；If breakthrough gap is relatively big, then use ferrum
Hammer beats breakthrough, makes the gap of breakthrough diminish；White lime and around oil is removed on outer wall at breakthrough with clear water, rust remover etc.
Paint and rust staining, and dry with cleaning cloth, it is allowed to expose the metal body of cleaning.
Step 2, immediately use adhesive block breakthrough, and adhesive is the modified phenolic adhesive using SiC filler to fill.
Step 3, after adhesive is fully cured, formed adhesive layer 3, the surface of adhesive layer be coated with last layer seal
Glue, makes fluid sealant cover all adhesive；Fluid sealant uses rubber-type fluid sealant.
After step 4, glue to be sealed are fully cured, form sealant layer 4, the periphery of cleaning sealant layer；
Step 5, coat a circle adhesive in the periphery of sealant layer, then top is provided with the metal of charge valve 6 at once
Case cover 5 (metal cap shell opener is slightly larger than sealant layer area) is in the periphery of sealant layer, and is bonded at adhesive, at metal
Pressure is applied, until metal case cancels pressure after cementing completely admittedly again outside case；
Step 6, employing inflator to metal case inner inflatable, make the intrinsic pressure power of metal case more than oil immersion by charge valve
Formula inside transformer pressure (normal staff persistently inflates with inflator, during until inflator is difficult to press down), then
Pull out inflator, close charge valve, i.e. complete the online fast blockage of oil-filled transformer.
