Design of the present utility model is: in the fuel tank case is stopped, have two high-voltage switch gear cabin and transformer rooms that are arranged in juxtaposition, there is each self-corresponding radiator in two cabins, two shared case lids in cabin are equipped with in the high-voltage switch gear cabin: high pressure inlet wire cable end, high voltage load switch, high-tension fuse and part annex; In transformer room, be equipped with: transformer core, voltage-regulation tap changer, low pressure outlet sleeve pipe and part annex; The side in two cabins is provided with corresponding panel, and panel cover is equipped with preceding storehouse dividing plate between the two preceding storehouses in having the preceding storehouse of shutter door.Can not have dividing plate between two cabins in the fuel tank, can adorn semiclapboard, can adorn whole baffle.If the dress semiclapboard, it all is immersed in the oil, in the bottom of semiclapboard valve is housed, and the line insulating support was equipped with at its top; If the dress whole baffle, the part that is in air chamber at whole baffle has air vent hole, and whole baffle is in oil immersion partly to be adorned the high pressure that has seal and cross thread casing, and the bottom surface in two cabins is equipped with gate gurgle valve respectively.
Advantage of the present utility model, beneficial effect are:
(1), the carbon granules because of switch motion electric arc charing insulating oil is produced can not drop on the transformer core, helps the safe operation of transformer.
(2), can be optimized design to distribution transformer, economical with materials reduces product cost, saves and takes up an area of the space.Adopt design of the present utility model, descend 20% than the box height of the platform of 630 kilovolt-amperes of equal capacity dress transformer, volume descends 12%, and transformer copper, iron gross weight 10% no-load loss that descends descends 27.7%, and the product total cost descends 10%.
(3), help the seriation design and the production of product.Cabinet design of the present utility model can be with the variation of capacity, and only the length direction at the transformer freight space changes thereupon, and the size in other cabins (storehouse) and the installation position of parts all can be constant, thereby, but simplified manufacturing technique is saved tooling device, reduces man-hour and cost.
(4), the maintenance but subdivision is drained the oil is when saving the check man.
