1. 1) CONSTRUCTIONAL ARRANGEMENT INTRODUCED IN ENERGY TRANSFORMER APPARATUS concerns a transformer (1) with main structure (2), equipped with means to receive handles (5), which is characterized by comprising a hollow semicircular projection (3) and (3A) incorporated into the main structure (2), in the upper longitudinal center, front and rear; by the handle (5) being flattened and configured by an arc (6) and being introduced into the hollow semicircular projection (3) and (3A); by the handle (5) installed in the hollow semicircular projection (3) and (3A) by a rivet (4) and (4A) under pressure; by the bodies of the rivets (4) and (4A) opening to lock the handle (5) in the hollow semicircular projection (3) and (3A).

Description

[001] This utility model patent application, as described above, concerns an evolutionary solution in an electrical power transformer used to change the nominal voltage value from input to output, either to increase or decrease the voltage. The improvement claimed herein, which is limited to construction and arrangement, particularly a flexible handle designed to facilitate the transport of the transformer, given its considerable weight, which causes discomfort and difficulties for the transporter. The disclosed arrangement differs from known solutions of this nature by presenting a series of improvements from a functionality standpoint, conferring optimized performance to the new construction introduced. FUNDAMENTALS OF THE TECHNIQUE [002] In order to provide veracity to the context of the introductory table, an explanation will be presented on the state of the art for transformers as well as the existing solutions, where it will be possible for a technician versed in the subject to recognize its restrictive aspects, in order to later discuss the advantages added with the introduction of the new "CONSTRUCTIVE ARRANGEMENT INTRODUCED IN ENERGY TRANSFORMER APPARATUS". [003] As is known to all of society, particularly in the electrical field, a transformer is a device designed to transmit electrical energy or power from one circuit to another, transforming voltages, currents, and/or modifying the values of the electrical impedance of an electrical circuit. It is an alternating current device that operates based on the electromagnetic principles of Faraday's Law and Lenz's Law. [004] A transformer consists of two or more coils or windings and a magnetic "path," or circuit, that "couples" these coils. There are a variety of transformers with different circuit types, but they all operate on the same principle of electromagnetic induction. [005] Smaller transformers intended for small equipment utilize the same principles of functionality. However, since the components that make up a transformer depend directly on the application, there are certain limitations regarding the size and dimensioning of these components. Despite frequent technological evolution, there is a physical limit that prevents major modifications to the structure of a transformer. The problem pointed out here by the applicant is not in the functionality or efficiency of a transformer, since this has been known for decades. The applicant draws attention to the fact that transformers are heavy, making them difficult to move and transport. In particular, the present improvement applies to small transformers used by ordinary consumers who frequently complain about the weight and difficulty in transporting the transformer. [006] In the patent literature, a solution was proposed, but it presented certain limitations and problems that are solved in the present invention, as is the case of MU 8600189-2 under the title "CONSTRUCTIVE ARRANGEMENT INTRODUCED IN AUTOTRANSFORMER", where it is foreseen that the autotransformer, in each of its casing sections, incorporates holes, which serve as mounting points for the handles; the handles are configured from a section of solid metal profile with a preferably circular cross-section, which is bent so that, in each handle, a gripping portion is defined, which is flanked by two mutually parallel orthogonal branches, which, at their respective ends, are bent so as to define two equally curved sections, which, when assembling each handle, are introduced into the holes provided in the casing sections. [007] This solution proposes ease of transporting the transformer due to its weight, however the inventor uses two metal handles with a certain rectangular configuration where the ends fit into the holes of the transformer with a certain pressure to remain in position. [008] When conducting an operational functionality analysis, it is possible to verify a series of restrictive aspects that limit its applicability and effectiveness when actually used in the transport of transformers, where among many, the main problems identified are listed: - The solution has two metal handles that heat up with the heating of the transformer, which can cause serious burns to the transporter's hands; - The solution has two metal handles that are only fitted into the holes and remain positioned due to the conformity of the angles that form the handles. An opposing force applied causes the handle to be removed; - The solution features two parallel metal handles with radial movements, and these handles meet at the upper center of the transformer, presenting contact between the straight transverse segments of the handles, a fact that can "bite" the transporter's hand; - The solution features two parallel metal handles in opposite regions that modify the center of gravity of the object, causing it to become unbalanced during transport; - The solution features two rigid metal handles that, despite having limited movements, will always be prese
