Description
Technical field
The invention belongs to substation's O&M service technique field, especially a kind of 1000kV extra-high voltage transformer low-voltage lead
Dismount platform.
Background technique
1000kV extra-high voltage transformer is equipment most crucial in ultra-high voltage transformer station, in the annual full station equipment annual test phase
Between, Repair of Transformer task is particularly important.Since transformer voltage grade is high, fieldwork meeting encounters many difficulties, wherein comparing
More typical action is the dismounting of low-voltage lead.
The transformer of 1000kV is very high to the dielectric level requirement of material, and low-tension bushing is higher than 500 kv transformers
It is many out, it is singly to increase the above porcelain vase part of seat just to reach 1.9 meters, while lead is heavy, dismounting is difficult.Draw in low pressure in recent years
In line dismounting operation, service personnel is difficult manually to touch the lead wire clamp of cannula tip, typically directly in the middle part of climbing to porcelain vase, with
Operation is carried out close to wire clamp.Service personnel is not allowed directly to climb porcelain vase to avoid breaking up porcelain vase according to safety requirement；It is another
Aspect, transformer body top capillary pipeline is complicated, and sufficient space does not set up ladder or scaffold.The above reason makes existing
Field operation is relatively difficult, not can guarantee personnel and equipment safety not only, but also makes lead dismounting work time-consuming and laborious, influences
Further work progress.
Existing lead method for dismounting is more original, ascends a height frequently with insulating ladder, sleeper etc. or padded tool reaches operation
Height operation, wherein insulating ladder is operation of ascending a height, and does not repeat, the application method of sleeper: first vertically tying up two sleepers in porcelain vase
On, then ridden on this two vertical sleepers with a lateral tie, fixation finally is tightened with rope, service personnel stands in transverse direction
Sleeper on carry out operation；Such method has the disadvantage that it is personnel safety first, and in high altitude operation, personnel safety is obtained
Less than guarantee；The objects such as followed by equipment safety, insulating ladder and sleeper may be touched during transporting transformer body
Various pipelines, while porcelain vase may be all damaged during fixed and personnel climb, influence its insulation performance；It is finally operation
Efficiency since lead is heavy, needs two people's compounding practices, narrow position is unfavorable for dismounting and carries out, operation when dismounting lead
Journey is slow, time-consuming and laborious.
For example, the patent document that publication No. is CN102510013A discloses a kind of box-type transformer maintaining platform, in transformation
The supporting table being detachably connected on device casing, it is high that the patent document that notification number is CN205081383U for another example discloses a kind of transformer
Although do-nothing operation platform, above two structure devise standing platform, but the structure of extra-high voltage transformer and low-voltage lead position
It sets and there is greatly difference with conventional transformer, use can not be matched.
Therefore, a kind of special platform of reply 1000kV extra-high voltage transformer low-voltage lead dismounting how is designed, it both can be with
It allows service personnel to there are enough spaces to dismount wire clamp, guarantees work safety, improve operating efficiency, and can avoid contact with
Porcelain vase eliminates damage hidden trouble of equipment, is the direction of those skilled in the art's long felt and research.
