Abstract

The transformer of the present invention comprises an external tank (1) delimiting a closed volume filled with oil. The tank includes vertical cooling fins (2), and the closed volume includes cavities located in the fins. Plates (3) in the shape of combs are set around the tank and include teeth penetrating between the fins. Side and front clearances separate the plates from the fins. The clearances have values lower than deformation values in free state of the fins subjected to a constraint greater than yield strength of the material. The fins are reinforced in a less complicated and inexpensive manner. The side clearances are determined, so that the fins touch the teeth before the fins reach elastic range while swelling according to contour for overpressure of the oil contained in the tank likely to be reached during certain tests or accidental circumstances, thus avoiding deformation of the fins and producing yield stress only if the overpressure of the oil is high.

Description

TANK TRANSFORMER FILLED WITH PETROLEUM AND PROVIDED WITH COOLING ASPECTS This invention consists of a complete filling with petroleum and of which tank walls are provided for with wind vanes. Said with oil are subjected to either conditions or tests. The enclosed volume relined with petroleum also extends into the depressions in which they are designed to be deformed when the flow is increased. One can conduct the transformer revolution at pressures that are so high that the deformations of the blades can reach and exceed their The plastic in such a way that they occur that are inadmissible given that definitive damage to the r One of this is described in Another that is about optimizing is a subject of the JP WO document? It describes a transformer with blades that are made more resistant by the cost in their strengths but in a way that is less and less expensive than patenting while allowing the objects to be reinforced. a trn comprising an external tank that imitates a closed volume filled with the tank with external cooling blades and the closed volume comprising depressions located on the blades and 1 that is covered with logs in the form of a camber located around the tank and teeth that penetrate between the spaces with spaces separating the plates of the blades and the empty spaces have v lores less than the values of deformation in the state of the blades subjected to a depression that exceeds an elastic limit of its mate r ta consequence of this provision is that the combas are opposite to the excessive ones of the blades and keep them in the ranqo of even for sisuscia 1 The teeth comprise them advantageously depre sions that give you a constitution in order not to excessively oppose the flow of from among the rans or rimed t very frequently will have several supers cros in many with the stop those of the blades asl will be supported by ls 1 rays installed on a superior surface of the tiers. The tie-down lines are common to all s ia s eta s s The r 1's can be threaded rods and nuts attached to the vari lias and they will be retained on them. The combs also adjust in addition to the fact that the mooring lines are distributed in two at different distances in order to retain the plates by opposite edges. According to the calculation, the tank is provided with blades of different sizes. and therefore have several dimensions of generally a rectangular section or in any case having blades over all its recommended that the plates extend as a band over full turns of the The best one can then be extended as a band over full turns and as they fill a better end. Loncos can be spread over a surface of the and they comprise tabs that are devoid of in plates belonging to the ta, now in the following show a non-excludable modality of Figure 1 is a general view of the transformer r Figure 1 of the combs and of Figur 3 and two of the pegs and the F and 6 show the supports for these pe i 1 of tot in the 1 and its external structure comprises in particular a tank 1 presented with a configuration of vertical exterior sides are provided with vertical blades 1 is surrounded by casinas 3 combs in this that form closed bands in the present listed as and in the height of tank 1 and which are suspended from tank 1 by the Figure shows that the combs 3 include teeth that penetrate a nested shape between the pairs of blades The teeth 6 without separating from the aspas 2 through the lateral spaces the frontal spaces 8 extend the ends of the blades 2 and the combs in the intervals The lateral spaces 7 at least are determined so that the blades per hfo according to the contour for overpressures Petroleum contents in tank 1 can be reached during tests or in certain circumstances focan teeth 6 before they reach range additional deformations the blades 2 are reduced and the elastic happens after the overpressures that are enough number of bands 4 is selected by the So that the blades 2 can not be deformed much more between two bands has Figure 2 that the teeth 6 have central depressions sa I vaqua rdando vertical to the blades so the 6 do not need the bottom of the blades 2 and leave the front spaces the front part of which also allows the flow to come in in pictures 3 and?
