For cooling in the course of the work to coil.Transformer was used after a period of time, it may appear that laying dust, or porcelain piece has and split
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 safeguarded
Deng, transformer needs to discharge cooling oil during being typically mounted at eminence, 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.：CN 105098632A Chinese patent 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；By the transformer core repaired, it is lifted into using a kind of door shaped stent suspended core instrument above transformer, peace
Install；Unload door shaped stent suspended core instrument and just complete this maintenance.The shortcoming of this method is：Will using door shaped stent suspended core instrument
Transformer core lifts maintenance, due in advance not discharging cooling oil, when transformer core lifts maintenance, is not fixed easily
And cooling oil can pollute Overhaul site and be not easily cleaned.
And for example Publication No.：CN 104009403A Chinese patent, which is disclosed, is exclusively used in the inspection to outdoor large transformer
Method is repaiied, bushing is overhauled, diaphragm type conservator is overhauled, dehydrating breather is unloaded, the exhaust on conservator top is opened
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 and 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
Pressure in valve injection on depressor, reduction diaphragm, secondary lead wires joint is firmly attached；The shortcoming of this method is：
If desired the device maintenance maintenance in transformer is accomplished by after first unnecessary part is dismantled, by the pressure in transformer
Power reduces and the oil in transformer is all put into clean, 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 cooling it is not in place, influence transformer
Normal work.
