Description
Technical field
The present invention relates to power Transmission equipment technical field, more particularly to a kind of oil immersed type transformation with inspection platform
Device.
Background technology
The chief component of transformer is iron core and coil, and cooling oil is provided with oil-filled transformer, cooling oil
For lowering the temperature in the course of the work to coil.After transformer is using a period of time, it may appear that laying dust, or porcelain piece has and splits
The phenomenons such as line, damage, or there is individual part to damage, contact is situations such as loosen, accordingly, it would be desirable to carry out periodic inspection to transformer,
So that transformer is in intact state, to ensure the normal work of transformer, such as transformer core is overhauled and is safeguarded
Deng, transformer is typically mounted at eminence, needs to discharge cooling oil during Repair of Transformer, and operation is inconvenient, and
Easily cause the damage of equipment and the injures and deaths of personnel.
Such as Publication No.：The Chinese patent of CN 105098632A discloses a kind of maintenance side of bench type transformer suspended core
Method, a kind of door shaped stent suspended core instrument of installation and maintenance suspended core on bench type transformer bottom channel-section steel；With in first step
A kind of door shaped stent suspended core instrument fixes bench type transformer suspended core；With a kind of door shaped stent suspended core work in first step
Tool slings bench type transformer suspended core；The bench type transformer sling is placed in position；Staff enters to it
Row maintenance and inspection；The transformer core that will have been repaired, transformer top, peace are lifted into using a kind of door shaped stent suspended core instrument
Install；Unload door shaped stent suspended core instrument and just complete this maintenance.The shortcoming of the method is：Will using door shaped stent suspended core instrument
Transformer core lifts maintenance, due to without in advance cooling oil is discharged, when transformer core lifts maintenance, not being fixed easily
And cooling oil can pollute Overhaul site and be not easily cleaned.
And for example Publication No.：The Chinese patent of CN 104009403A discloses the inspection being exclusively used in outdoor large transformer
Method is repaiied, bushing is overhauled, diaphragm type conservator is overhauled, unload dehydrating breather, open the exhaust on conservator top
Stopple, feeding leak detection air pressure, order oil is escaped from steam vent, closes exhaust stopple, is installed and is inhaled warm device, opens conservator with device body
Oil duct connecting valve；The oil in conservator is drained using conservator draining valve, the pipeline for passing to and inhaling warm device is removed, by insulating oil by becoming
Valve injection on depressor, reduces the pressure in diaphragm, and secondary lead wires joint is firmly attached；The shortcoming of the method is：
If desired after being accomplished by first dismantling unnecessary part to the device maintenance maintenance in transformer, by the pressure in transformer
Oil in transformer is simultaneously all put clean by power reduction, and it is net that the method for discharge can not say that oil is all drained, especially bottom half
Cooling oil, after working long hours, bottom half have cooling oil precipitation, cause cooling oil cool down it is not in place, influence transformer
Normal work.

The course of work：
Alarmed when oil product detection means 8, it is necessary to when being changed to the insulating oil in transformer, first by transformer-cabinet
Oil-out 5 above 1 side is opened and connects outside fuel reserve tank.Lift dividing plate of changing oil simultaneously during iron core 2 is lifted
6, and the speed for being lifted, less than the speed of oil-feed pump oil-feed, dividing plate 6 of changing oil is by original insulating oil in transformer-cabinet 1 along case
Upwardly, the insulating oil after extruding flows into outside fuel reserve tank to the inwall of body 1 by oil-out 5, when dividing plate 6 of changing oil rise into
During 4 top of hydraulic fluid port, outside oil-feed pump is opened to being filled with new insulating oil in transformer-cabinet 1, and is filled with the same of oil in oil-feed pump
When, to changing oil, dividing plate 6 applies upward thrust, accelerates the speed that change oil dividing plate 6 and iron core 2 are lifted up, not only laborsaving but also section
Can, and change oil dividing plate 6 rise during, now ball float 66 in the case where being risen by oil-feed pump input pressure, ball float
66 middle parts for being stuck in hollow hole 61 are not moved, and removable cover 63 is under the attraction of magnetic pole 62, is fixedly installed on hollow hole 61
Upper surface, totally-enclosed hollow hole 61.When iron core 2 removes transformer-cabinet 1, when dividing plate 6 of changing oil reaches oil-out 5, close fuel-displaced
Mouth 5, unties the dividing plate 6 of changing oil for being arranged on the bottom of iron core 2, stops oil-feed pump oil-feed, and the bottom of dividing plate 6 of now changing oil loses oil-feed pump
The support of pressure, ball float 66 drives removable cover due to being sunk by the Action of Gravity Field of itself by connecting line 65 and fixed pulley 64
The sidesway of plate 63, opens hollow hole 61, and by hollow hole 61, insulating barrier is moved down rapidly new insulating oil, until transformer-cabinet 1
Bottom, overlaps with the bottom of transformer-cabinet 1, and ball float 66 blocks and is placed in hollow hole 61 again, and removable cover 63 loses connecting line 65
Traction, under the attraction of magnetic pole 62, the upper surface of hollow hole 61 is returned back to, until completely enclosed hollow hole 61, now changes oil
Dividing plate 6 is changed oil end, and is restarted when changing oil next time.
