Description
Technical field
The present invention relates to power Transmission equipment technical field more particularly to a kind of oil immersed type changes with oil product detection device
Depressor.
Background technique
The chief component of transformer is iron core and coil, and cooling oil is provided in oil-immersed transformer, cooling oil
For cooling down during the work time to coil.Transformer is after a period of use, it may appear that dust accumulation or porcelain piece, which have, to be split
Phenomena such as line, damage, or have situations such as individual part damage, contact loosen, therefore, it is necessary to carry out periodic inspection to transformer,
So that transformer is in intact state and is such as overhauled and safeguarded to transformer core to guarantee the normal work of transformer
Deng, transformer is typically mounted at eminence, during Repair of Transformer needs that cooling oil is discharged, 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 tool of installation and maintenance suspended core on bench type transformer bottom channel steel；With in first step
A kind of door shaped stent suspended core tool fixes bench type transformer suspended core；With one of first step door shaped stent suspended core work
Tool slings bench type transformer suspended core；The bench type transformer sling is placed in position；Staff to its into
Row maintenance and inspection；The transformer core that will have been repaired is lifted into above transformer using a kind of door shaped stent suspended core tool, peace
It installs；It unloads door shaped stent suspended core tool and just completes this maintenance.The disadvantages of the method are as follows：It will using door shaped stent suspended core tool
Transformer core lifts maintenance, since cooling oil not being discharged in advance, when transformer core lifts maintenance, is not fixed easily
And cooling oil can pollute Overhaul site and be not easily cleaned.
For another example Publication No.：The Chinese patent of CN 104009403A discloses the inspection being exclusively used in outdoor large transformer
Method is repaired, bushing is overhauled, diaphragm type conservator is overhauled, unloads dehydrating breather, opens the exhaust on conservator top
Stopple is sent into leak detection air pressure, oil is enabled to escape from gas vent, closes exhaust stopple, and warm device is inhaled in installation, opens conservator and 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, insulating oil is passed through into change
Valve injection on depressor, reduces the pressure in diaphragm, secondary lead wires connector is firmly attached；The disadvantages of the method are as follows：
If desired after to the device maintenance maintenance in transformer with regard to needing first to dismantle unnecessary component, by the pressure in transformer
Power reduces and all puts it clean the oil in transformer, which cannot say that oil is all discharged, especially the bottom of box
Cooling oil, after working long hours, the bottom of box have cooling oil precipitating, cause cooling oil cooling it is not in place, influence transformer
Normal work.
