Abstract
The present invention discloses a liquid-immersed type distribution transformer tank. The tank comprises a tank body and a tank lid which are in coordinating connection, the tank body is shaped as a cuboid or a cube with an opening at the top part, the top part of the tank body is provided with a tank edge horizontally stretching outwards, a sealing adhesive layer is disposed on the tank edge, and the tank lid is fixedly connected with the tank bod through the sealing adhesive layer. A technical connection method of the liquid-immersed type distribution transformer tank is also disclosed. According to the transformer tank, a sealing adhesive is adopted to fit the tank body and the tank lid, the sealing performance of the tank is greatly raised, the phenomenon of tank oil leakage can be effectively solved, using security of a transformer in an operating process is thus raised, and the service life of the transformer is thus prolonged. With adoption of the technical connection method, the assembling efficiency of the tank is greatly raised, and the production cost of the tank is thus saved.
Description
Technical field
The present invention relates to a kind of liquid immersion type distribution transformer fuel tank, also relate to the technique method of attachment of above-mentioned liquid immersion type distribution transformer fuel tank.
Background technology
Liquid soaking transformer fuel tank is made up of case lid and casing, becomes one by placing acrylonitrile-butadiene rubber sealing strip at case lid and centre, casing case edge and be connected and fixed with multiple bolt.Casing case is respectively welded with a round steel in order to location along outer edge in surrounding, and sealing strip is placed in the middle of two round steel, then case lid is placed on fuel tank assigned position, and aligning case lid and case, along upper screwed hole, are placed on request and tight a bolt.For preventing seepage oil condition, pitch of bolts is unsuitable excessive, and the bolt quantity being therefore used for connecting is more, and installation effectiveness is also lower.This structure requires also higher to fuel tank processing technology, if fuel tank edge has distortion or insufficient, the out-of-flatness of round steel welding, or there is flaw in lap joint place of acrylonitrile-butadiene rubber sealing strip, capital directly affects sealing effectiveness, even cause fuel tank leakage of oil, greatly reduce transformer useful life, also there is potential safety hazard simultaneously.Therefore in current fuel tank Joining Technology, case lid is connected with sealing strip by bolt with casing, not only make fuel tank there is leakage of oil hidden danger, and fuel tank efficiency of assembling is low.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of good seal performance, safe and reliable liquid immersion type distribution transformer fuel tank.
The technical problem that the present invention also will solve is to provide the technique method of attachment of above-mentioned liquid immersion type distribution transformer fuel tank, and this technique method of attachment substantially increases the efficiency of assembling of fuel tank.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is as follows:
A kind of liquid immersion type distribution transformer fuel tank, comprise the casing and case lid that cooperatively interact and connect, described casing is open-topped cuboid or square, described casing top is provided with the case edge of outside horizontal-extending, described case is along being provided with sealant layer, and described case lid is fixedly connected with described casing by described sealant layer.
Further preferably, the width on described case edge is 1/5 ~ 1/6 of described casing width, and case is along casing and case lid can be made in such width better to combine.
Further preferably, the thickness of described sealant layer is 3 ~ 4cm, if sealant layer is too thick, can improve the production cost of fuel tank, if sealant layer is too thin, then and the sealing effectiveness do not reached and sticky glutinous effect.
The technique method of attachment of above-mentioned liquid immersion type distribution transformer fuel tank, comprises the steps:
Step 1, casing case edge is made a call to the fluid sealant of a circle desired thickness, and the casing stamping fluid sealant leaves standstill a period of time in atmosphere;
Step 2, is combined in case lid on casing, carries out vacuum oil by vacuum oil technological requirement to oil tank of transformer, and oil injecting speed controls in maintenance vacuum lower than 0.13KPa.
Wherein, in step 1, described time of repose is 2 hours, within 2 hours, has not allowed weight to be pressed in case along position in static condition at casing, leaves standstill and sealant layer within 2 hours, can better be made to play its sealing and sticky glutinous effect.
Beneficial effect: the present invention compared with prior art, have the following advantages: oil tank of transformer of the present invention adopts fluid sealant casing and case lid to be sealed and fits, substantially increase the sealing property of fuel tank, thus effectively can solve the phenomenon of fuel tank leakage of oil, and then improve the safety in utilization of transformer in running, and then extend the useful life of transformer; The technique method of attachment of oil tank of transformer of the present invention substantially increases the efficiency of assembling of fuel tank, thus has saved the production cost of fuel tank.
