Abstract
The utility model discloses an iron core plate anti-creeping-down device which comprises a supporting plate, an insulation screw rod, a first fastening piece used for fixing the supporting plate on an iron core clamping piece and a second fastening piece used for fixing the insulation screw rod on the supporting plate. One end of the insulation screw rod pushes against a maximum iron core plate so as to provide resistance in the falling direction an iron core plate. According to the iron core plate anti-creeping-down device, the supporting plate is mounted on the iron core clamping piece, the insulation screw rod is mounted on the supporting plate, one end of the insulation screw rod pushes against the maximum iron core plate, and therefore the resistance is provided in the falling direction of the iron core plate to prevent the iron core plate from creeping down.
Description
Technical field:
The utility model belongs to transformer manufacture technology, relates to a kind of lamination landing device that prevents.
Background technology:
Along with the continuous development of power industry, the transportation range of transformer is more and more far away.Because the road conditions of complexity and the velocity perturbation of means of transportation in the transportation are easy to cause the loosening of the more inner parts of transformer.And transformer core minimum level lamination is because away from center of effort, and the direction of lamination is consistent with the terrestrial gravitation direction, just be easy to cause the landing of this part lamination, and then cause lamination to touch near metalwork (folder etc.), transformer is in the state of multipoint earthing, causes partial discharge.As everyone knows, transformer transports the on-the-spot pendant-core examination that carries out that has only ratio seldom behind the scene to, and the overwhelming majority is not carried out on-the-spot pendant-core examination.After the transformer operation, thereby, also caused the influence on the reputation for our transformer producer for the user causes serious consequence.
And the appearance of this device has then well solved above problem, has both guaranteed transformer site safety, stable, relieved use, can eliminate because economy that this type of problem causes and influence on the reputation for man of transformer factory again.
The utility model content:
The utility model proposes a kind of lamination landing device that prevents.
The technical scheme that the utility model adopted is:
A kind of lamination landing device that prevents, comprise support plate, insulation blanket stud, support plate is fixed to first securing member on the core clamping, and insulation blanket stud is fixed to second securing member on the support plate, an end of described insulation blanket stud props up the minimum level lamination to provide resistance at the lamination falling direction.
As preferred embodiment of the present utility model, described first securing member comprises bolt and packing ring.
As preferred embodiment of the present utility model, described second securing member is the insulation nut.
As preferred embodiment of the present utility model, described insulation nut comprises the first insulation nut and the second insulation nut.
The utility model has the following advantages at least: the utility model is installed support plate on core clamping, insulation blanket stud is installed on the support plate, and an end and the minimum level lamination of described insulation blanket stud offset, thereby, provide resistance at the lamination falling direction, prevent the lamination landing.
Description of drawings:
Fig. 1 is that the utility model device is at the installation site of transformer core schematic diagram.
Fig. 2 is the structure chart of the utility model device.
1 support, 6 packing rings
2 insulation blanket studs, 7 minimum level laminations
The insulation of 3 first insulation nuts, 8 folders
4 second insulation nuts, 9 lower clamping pieces unshakable in one's determination
5 bolts
Embodiment:
Below in conjunction with accompanying drawing embodiment of the present utility model is described:
Fig. 1 for this device at the installation site of transformer core schematic diagram, general high and low pressure folder is respectively installed 4, quantity can be adjusted according to the size of transformer core.
See also shown in Figure 2ly, the utility model prevents that lamination landing device from comprising support plate 1, insulation blanket stud 2, the first insulation nut 3, the second insulation nut 4, bolt 5, packing ring 6.Bolt 5, packing ring 6 are fixed on support plate 1 on the folder, the first and second insulation nuts 3,4 are fixed on insulation blanket stud 2 on the support plate, other one and unshakable in one's determination little level lamination of insulation blanket stud are engaged togather, thereby on the lamination falling direction consistent, form one and laterally bear resistance, to reach the effect that prevents the lamination landing with terrestrial gravitation.
This device is special in to solve very simple, a practical design of this type of problem that is run in the installation process at transformer scene, support plate 1, the first insulation nut 3, the second insulation nut 4, bolt 5, the packing ring 6 of this device that at diameter is the product design of φ 400 to φ 770 be universal standard part all, need not difference processes, and has just specified the insulation blanket stud of four kinds of different lengths on insulation blanket stud 2 according to the difference of diameter.The difficulty of processing of all component is little, and cost is low, and has interchangeability, has both saved cost, has well solved our lamination landing matters of long-term puzzlement again.Stopped the generation of problem, for enterprise has created value.
