Description
Technical field
The utility model belongs to service kit technical field in power system transformer substation, relates to a kind of on-load tap-changer of transformer service kit, overhauls for on-load tap-changer of transformer.
Background technology
At present in electric power system, 35kV and above transformer generally adopt on-load voltage regulating switch to carry out line voltage adjustment.The aging of metalwork is caused, so on-load voltage regulating switch needs to lift by crane service work after operation a period of time because on-load voltage regulating switch can produce electric arc in charged process of transferring the files.Conventional service work all needs on-load voltage regulating switch to move away from transformer, moves to ground and carries out service work, waste time and energy, and there is potential safety hazard in on-load voltage regulating switch handling process.
Summary of the invention
The purpose of this utility model is: provide a kind of on-load tap-changer of transformer service kit, realize the maintenance of on-load voltage regulating switch on the transformer, overcome the difficult problem that the maintenance of existing on-load tap-changer of transformer needs lifting carrying, facilitate service work, ensure site examining and repairing work safety.
Technical solution of the present utility model is: this on-load tap-changer of transformer service kit comprises base, horizontal hanging arm, chain block, support bar and maintenance pallet, and two support bars are arranged on base by bolt symmetry; Support bar is provided with fixing hole, and horizontal hanging arm is connected on support bar by fixing hole and bolt; Connect chain block in the middle of horizontal hanging arm, the bottom of support bar is bolted strutting piece, and the maintenance pallet of shape as " recessed " type is fixed on strutting piece by fastening bolt.
Wherein, a support bar is telescopic support, and be made up of lower beam and upper boom, lower beam is connected with base, and upper boom is extracted out in the middle of lower beam, and upper boom and lower beam are fixed by latch.
The utility model has the advantages that: structure is simple, is connected firmly, with low cost, easy to use, shorten the repair time, reduce manpower, avoid transformer oil stain to spread, promote service work safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, this on-load tap-changer of transformer service kit comprises base 1, horizontal hanging arm 5, chain block 6, support bar 7 and maintenance pallet 8, two support bars 7 and is arranged on base 1 by bolt symmetry; Support bar 7 is provided with fixing hole 4, and horizontal hanging arm 5 is connected on support bar 7 by fixing hole 4 and bolt; Connect chain block 6 in the middle of horizontal hanging arm 5, the bottom of support bar 7 is bolted strutting piece 9, and the maintenance pallet 8 of shape as " recessed " type is fixed on strutting piece 9 by fastening bolt 10.
Wherein, a support bar 7 is telescopic support, and be made up of lower beam 2 and upper boom 11, lower beam 2 is connected with base 1, and upper boom 11 is extracted out in the middle of lower beam 2, and upper boom 11 is fixed by latch 3 with lower beam 2.
During installation, base 1 is mated with transformer prolongs by the draw-in groove of matrix, and draw-in groove strap bolt hole, mate with the fixed screw that transformer prolongs, firm banking 1; When on-load tap-changer of transformer maintenance carried out by needs, on-load voltage regulating switch is hung transformer by chain block 6, at correct position, on-load voltage regulating switch is hovered, again on-load voltage regulating switch is placed on maintenance pallet 8 by chain block 6, on-load tap-changer of transformer maintenance on the transformer can be carried out.
