Description
Technical field
The utility model relates to electric system field of tool, in particular to a kind of power transformer load tap changer inspection
Repair lifting device.
Background technique
Transformer will generate voltage drop in power transmission process, and change with the variation of user side load.System
The fluctuation of voltage will cause the biggish variation of voltage plus the variation of user side load.Before realizing reactive power in-situ balance
It puts, when variation in voltage is more than definite value, on-load regulator transformer can act after certain delay, be adjusted simultaneously to voltage
Keep voltage stabilization." power system technology directive/guide " provides preferably to consider the change of at least one level voltage to 110kV and following transformer
Depressor uses bringing onto load voltage regulating mode.But transformer configuration on-load voltage regulation tap, also reduces the reliability of transformer station high-voltage side bus.
Bringing onto load adjusts voltage branch point, and not only itself is unreliable, while also adding the complexity of transformer whole design.So plus
Strong load ratio bridging switch operation and maintenance and maintenance are essential.Substation field tap switch maintenance at present, which generally uses, hangs
Vehicle hangs out its inner core, help keeping by special messenger, then overhauls to each component in its inside, increases operating cost.In addition, for
Indoor substation, narrow space, crane can not carry out lifting operation, can only carry away by manpower, both increase the work of service personnel
Industry risk, and it is difficult to ensure that repair quality.
Utility model content
The purpose of this utility model is to overcome the above problems, have provided a kind of power transformer load tap changer
Overhaul lifting device.
The utility model provides a kind of power transformer load tap changer maintenance lifting device, it is characterised in that: institute
The power transformer load tap changer maintenance lifting device stated, including pedestal 1, rotatable column 2, hydraulic jack 3 can stretch
Contracting boom 4, electrical hoist 5, rotating handles 6；
Wherein: rotatable column 2 is installed on pedestal 1, hydraulic jack 3 is installed on rotatable column 2, it is scalable to hang
4 tail end of arm and rotatable 2 top of column are hinged, and the middle and back and 3 upper end of hydraulic jack of scalable boom 4 are hinged, electric rolling
It raises machine 5 and is mounted on scalable 4 front end of boom, rotating handles 6 are mounted on rotatable column 2.
5 top of electrical hoist has the suspension arrangement that can be rotated automatically.
1 bottom of pedestal has mounting hole.
Adjustable damping device is had between the rotatable column 2 and pedestal 1.
The telescoping mechanism of the scalable boom 4 is hydraulic drive mechanism.
The electrical hoist 5 has diaphragm autobrake system.
The scalable boom 4 can stepping adjustment length.
V-type load ratio bridging switch feature is often selected for 66 kv transformers, pattern, slinger are lifted using single arm type
Tool pedestal is mounted in tap switch shaft coupling fixed pallet, adjusts tap switch using scalable boom and hydraulic jack
After Hoisting Position, starting electrical hoist makes tap switch inner core be detached from oil cabinet of tap switches, utilizes column rotation function, maintenance
Personnel can complete site maintenance operations on transformer body or ground.
The advantages of the utility model:
Power transformer load tap changer described in the utility model overhauls lifting device, and theory structure is simple, uses
It is convenient.Rotatable column can complete 360 degree rotation, and service personnel may be implemented in transformer body and overhaul up and down, be more convenient and
It is safer；Scalable boom can be adjusted with stepping according to live distance, meet the needs of different situations；High-power electric
Hoist engine maximum lifting weight is big, has diaphragm autobrake system, it is ensured that load, lifting, self-locking function.Each section component can
Disassembly, easy to carry, assembling also facilitates when field operation, is not take up larger space.Both guaranteed service personnel's operation personal safety,
Operating efficiency and the cost of overhaul can be improved again.
