Description
Technical field
The present invention relates to power Transmission equipment technical field, more particularly to a kind of single-phase oil immersion type transformer.
Background technology
The chief component of transformer is iron core and coil, and iron core plays magnetic conduction and skeleton in transformer,
The quality of its crudy directly affects the quality of transformer.At present, transformer core typically all uses laminated core structure structure,
It is different from the manufacture of Miniature transformer iron core in the fabrication process, is mainly reflected on the closed assembly and hoisting method of iron core, transformation
As long as device iron core typically after the completion of closed assembly, is directly sling from workbench with suspender on workbench, makes it from horizontal position
Put and be changed into upright position and stand up, be easy to make iron core deform during lifting, cause the seam between silicon steel sheet
Become big, iron core end face becomes uneven, and the open circuit loss and noise of such transformer can all greatly increase；In addition, so very
Security incident easily occurs, causes the damage of equipment and the injures and deaths of personnel.
Such as Publication No.：CN105098632A 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

Recycling.
And for example Publication No.：CN104009403A Chinese patent discloses the maintenance being exclusively used in outdoor large transformer
Method, bushing is overhauled, diaphragm type conservator is overhauled, unload dehydrating breather, open the steam vent on conservator top
Plug, leak detection air pressure is sent into, order oil escapes from steam vent, closes exhaust stopple, and warm device is inhaled in installation, opens the oil of conservator and device body
Road 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 transformation
Valve injection on device, reduces the pressure in diaphragm, secondary lead wires joint is firmly attached；The position of the switch number can be by indicating
Disk provides, when making tap position needed for pointer alignment, then the screw that is tightened.The shortcomings that this method is：If desired to transformer
In device maintenance maintenance just need after first unnecessary part is dismantled, by the pressure reduction in transformer and by transformation
Oil in device is all put clean, operating time length, wastes time and energy, and repair it is good after also need that part is loaded onto into original position successively, if
There is damage to be just unfavorable for reusing for transformer in unloading process, add cost.
