Form sediment substantial amounts of filth, when the environment residing for when dry-type transformer is moister, in filth dissolve material will molten water, thus
The insulating surface of dry-type transformer forms conducting film, finally results in the generation of pollution flashover phenomenon, dry-type transformer pollution flashover for a long time
Phenomenon can increase the increase of insulating element surface Leakage Current, thus shortening dry-type transformer service life, affects user power utilization
Quality, or even pollution flashover accident and personal safety accident can occur.
Dry-type transformer discharge end is high-voltage terminal end, and the earth terminal the shortest with high-voltage terminal end creepage distance is folder pad
Block, when dry-type transformer surface deposition is filthy in a large number, if the humidity of its local environment is larger, high-voltage terminal end and folder pad
Pollution flashover phenomenon, prior art such as Chinese patent can occur between block（CN201673781U）Disclosed waterproof anti-pollution dry type transformation
Device, in this patent, high-voltage coil and low-voltage coil is epoxy resin casting coil, and described epoxy resin casting coil is dry change high pressure pour mass,
Wherein dry become the side of high pressure pour mass and be respectively equipped with high-voltage terminal end, the dry end face becoming high pressure pour mass supports and being provided with folder
Part cushion block, this patent, by using RPTV antifouling flush paint application, makes dry-type transformer insulation antifouling work voltage improve, thus subtracting
The generation of few pollution flashover phenomenon is it is ensured that the safe operation of power equipment；But RPTV antifouling flush paint is somewhat expensive, large area applies
During dress, cost is higher, and during application RPTV antifouling flush paint, environmental condition is required higher.
Content of the invention
The purpose of this utility model is to provide a kind of dry dry-type transformer becoming high pressure pour mass and having this pour mass,
To reduce the expense of antifouling work.
For achieving the above object, a kind of dry dry-type transformer becoming high pressure pour mass and there is this pour mass of this utility model
Technical scheme be：A kind of dry-type transformer, becomes high pressure pour mass including dry, the end face of high pressure pour mass supports and is provided with folder
Cushion block, the dry side becoming high pressure pour mass is provided with high-voltage terminal end, in high-voltage terminal on the side of described change high pressure pour mass
It is provided with full skirt between end and folder cushion block.
Described full skirt is semicircle, the dead in line at wherein semicircular axis and high-voltage terminal end.
It is provided with the full skirt of more than twice between high-voltage terminal end and folder cushion block.
Full skirt is vertically set on the side of dry change high pressure pour mass.
A kind of dry become high pressure pour mass, include being arranged on the high-voltage terminal end of dry change high pressure pour mass side and be used for supporting
The end face of folder cushion block, the side of described high pressure pour mass sets between the end face of high-voltage terminal end and dry change high pressure pour mass
There is full skirt.
Described full skirt is semicircle, the dead in line at wherein semicircular axis and high-voltage terminal end.
It is provided with the full skirt of more than twice between high-voltage terminal end and folder cushion block.
Full skirt is vertically set on the side of dry change high pressure pour mass.
The beneficial effects of the utility model are：A kind of dry-type transformer, becomes high pressure pour mass including dry, high pressure pour mass
Support on end face and be provided with folder cushion block, the dry side becoming high pressure pour mass is provided with high-voltage terminal end, described change high pressure pour mass
Side on be provided with full skirt between high-voltage terminal end and folder cushion block；This utility model passes through in high-voltage terminal end and folder pad
Between block, setting full skirt to reduce the expense of antifouling work while antifouling work phenomenon occurs.

Fig. 2 is the A-A partial sectional view of Fig. 1；
Fig. 3 is dry type transformer structure schematic diagram.
In figure：1- does and becomes high pressure pour mass, 2- high-voltage terminal end, 3- full skirt, 4- folder cushion block, 5- end face.
Specific embodiment
A kind of specific embodiment of dry-type transformer of the present utility model, as shown in Figure 1 to Figure 3, this dry-type transformer bag
Include dry change high pressure pour mass 1 and folder cushion block 4, the dry side becoming high pressure pour mass 1 is provided with high-voltage terminal end 2, folder cushion block 4
It is arranged on the end face 5 of dry change high pressure pour mass 1, do on the side becoming high pressure pour mass 1 and be located at high-voltage terminal end 2 and folder
It is provided with full skirt 3, wherein full skirt 3 is semicircle, and the dead in line at semicircular axis and high-voltage terminal end 2, umbrella between cushion block 4
The effect of skirt is the creep age distance on the one hand increasing between high-voltage terminal end and folder cushion block, thus reducing the generation of pollution flashover phenomenon
