Description
Technical field
This utility model relates to power transmission equipment technical field, particularly relate to a kind of single-phase oil immersion type transformator and
Its monitoring system.
Background technology
The key component of transformator is iron core and coil, and iron core plays the work of magnetic conduction and skeleton in transformator
With, the quality of its crudy directly affects the quality of transformator.At present, transformer core the most all uses folded
Chip core structure, is different from the manufacture of Miniature transformer iron core in the fabrication process, is mainly reflected in iron core
On closed assembly and hoisting method, as long as transformer core is general after on work platforms, closed assembly completes, direct with suspender
Sling from work platforms so that it is become upright position from horizontal level and stand up, hold very much during lifting
Easily making iron core deform, cause the seam between stalloy to become big, iron core end face becomes uneven, so
The open circuit loss of transformator and noise all can be greatly increased；It addition, be so easy to security incident, cause
The damage of equipment and the injures and deaths of personnel.
Such as Publication No.: the Chinese patent of CN 105098632A discloses the dimension of a kind of bench type transformator suspended core
Repair 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
Bench type transformator suspended core is fixed by a kind of door shaped stent suspended core instrument in first step；With in first step
A kind of door shaped stent suspended core instrument bench type transformator suspended core is sling；The bench type transformator sling is placed
In position；Staff carries out maintenance and inspection to it；The transformer core that will have keeped in repair, utilizes a kind of door
Type support suspended core instrument is lifted into above transformator, installs；Unload door shaped stent suspended core instrument just to complete

And for example Publication No.: the Chinese patent of CN 104009403A discloses and is exclusively used in outdoor large transformator
Repair method, bushing is overhauled, diaphragm type conservator is overhauled, unloads dessicator, open
The aerofluxus stopple on conservator top, sends into leak detection air pressure, and order oil escapes from steam vent, closes aerofluxus stopple, peace
Temperature device inhaled by dress, opens the oil duct connecting valve of conservator and device body；Conservator draining valve is utilized to drain the oil in conservator,
Remove the pipeline passing to inhale temperature device, insulating oil injected by the valve on transformator, reduce the pressure in diaphragm,
Secondary lead wires joint is firmly attached；The position of the switch number can be given by instruction dish, makes required point of pointer alignment
When connecing position, then the screw that is tightened.The shortcoming of the method is: if desired the device in transformator is overhauled inspection
Repair after being accomplished by first being dismantled by unnecessary parts, the pressure in transformator is reduced and by transformator
Oil is all allowed to dry only, and the operating time is long, wastes time and energy, and also needs after maintenance well to be loaded onto by parts in situ successively,
If there being damage to be just unfavorable for reusing of transformator in unloading process, add cost.
