Description
Technical field
It the utility model is related to a kind of transformer, and in particular to a kind of lightning protection transformer.
Background technology
Transformer is typically made up of iron core, high-tension coil and low-voltage coil.Existing transformer is typically all not provided with
The lightning protection device of effect, this for operate in outdoor transformer for be one larger the defects of, can make transformer and with change
The electrical equipment of depressor connection all suffers from larger thunderbolt risk.
Utility model content
In view of the shortcomings of the prior art, the utility model aims to provide a kind of lightning protection transformer, when being struck by lightning
Each part of inside transformer can be effectively protected to be not damaged by.
To achieve these goals, the utility model adopts the following technical scheme that：
A kind of lightning protection transformer, including iron core and the high-tension coil and low-voltage coil that are respectively arranged on the iron core both sides；Also
Include grounded metal enclosure；The outer top of the grounded metal enclosure is welded with least a lightning-arrest thimble, inner surface and then covered
It is stamped at least one layer of insulating barrier；The side of the iron core is provided with storage tank, and the inner surface of storage tank is provided with screen layer, the low pressure
Coil is set around on a skeleton and in the storage tank；The high-tension coil is set around the opposite side of the iron core；Institute
State storage tank and be provided with opening towards the direction opposite with high-tension coil；The both sides of the grounded metal enclosure are provided with electric network source electricity
Cable stretches into hole and power supply for electrical equipment cable stretches out hole.
Further, the high-tension coil is parallel with a discharge tube for connecting the terminals of power supply.
Further, the outer surface of the high-tension coil is sequentially provided with insulating barrier, screen layer and insulating barrier, institute from inside to outside
State shielding layer grounding.
The beneficial effects of the utility model are：Each portion of inside transformer can be effectively protected when being struck by lightning
Part is not damaged by.
Brief description of the drawings
Fig. 1 is the diagrammatic cross-section of shell mechanism of the present utility model；
Fig. 2 is the diagrammatic cross-section of each modular construction in inside of the present utility model.
Embodiment
Below with reference to accompanying drawing, the utility model will be further described, it is necessary to which explanation, the present embodiment is with this skill
Premised on art scheme, detailed embodiment and specific operating process are given, but the scope of protection of the utility model is not
It is limited to the present embodiment.
As shown in Figure 1 and Figure 2, a kind of lightning protection transformer, including iron core 6 and the high-voltage line for being respectively arranged on the both sides of iron core 6
Circle 7 and low-voltage coil 8；Also include grounded metal enclosure 1；The outer top of the grounded metal enclosure 1 is welded with least one
Lightning-arrest thimble 2, inner surface is then covered with least one layer of insulating barrier 3；The side of the iron core 6 is provided with storage tank 9, storage tank 9
Inner surface is provided with screen layer 10, and the low-voltage coil 8 is set around on a skeleton 11 and in the storage tank 9；The height
Line ball circle 7 is set around the opposite side of the iron core 6；The storage tank 9 is provided with opening 91 towards the side opposite with high-tension coil 7
To；The both sides of the grounded metal enclosure 1 stretch into hole 4 provided with electric network source cable and power supply for electrical equipment cable stretches out hole 5.
The operation principle of the lightning protection transformer is：In thunderstorm weather, the electric current of thunder and lightning is passed through ground connection by lightning-arrest thimble
Metal shell imports ground, so as to avoid shell puncture of the thunder and lightning by transformer, thunder and lightning can also be avoided to pass through inside transformer
Part, so as to the electrical equipment damaged the part of inside transformer and be connected with transformer.In grounded metal enclosure
Surface adds a layer insulating, can further prevent electric current from flowing through each part of inside transformer.
And storage tank is set in the side of iron core, and in the inner surface setting screen layer of storage tank, then contingency can be ensured
There is thunder-strike current to enter inside transformer, can also prevent that low-voltage coil is breakdown, and then protect the use being connected with low-voltage coil
Electric equipment.The screen layer can use ferromagnetic material.
Further, the high-tension coil 7 is parallel with a discharge tube 12 for connecting the terminals of power supply.Put by setting
Fulgurite, can be by the blown fuse on the work electric network source path of discharge tube, so as to realize when being struck by lightning
Protect high-tension coil.
Further, the outer surface of the high-tension coil 7 is sequentially provided with insulating barrier 13, screen layer 14 and insulation from inside to outside
Layer 15, the shielding layer grounding.Further high-tension coil can be protected by insulating barrier, screen layer and insulating barrier.
For those skilled in the art, technical scheme that can be more than and design, make various corresponding
Change and deformation, and all these change and deformation should be construed as being included in the utility model claims protection domain it
It is interior.
