Description

[0010] Explained superficially, the improvement is further detailed through the drawings as follows:

[0011] FIG. 1shows the equipment in box format and, on the scheme on the side, the diagram of its electronic circuit for a power from an alternating current supply (electrical grid) with 95 to 250V voltage;

[0012] FIG. 2shows the equipment in box format and, on the scheme on the side, the diagram of the electronic circuit for a power from a direct current supply (battery) with voltage from 9 to 30V.

[0013] In compliance with the attached drawings, the EQUIPMENT ELECTRO-ELECTRONIC CIRCUIT IMPROVEMENT FOR ANTI-CORROSION TREATMENT ON METAL SURFACES, consists of equipment for anti-corrosion treatment system on metal surfaces, under box construction, being one box (1) with cover (1a) mounted with circuit (C1) for alternating current with voltage from 95 to 250V and one box (2) with cover (2a) mounted with circuit (C2) for direct current with voltage from 9 to 30V.

[0014] In the configuration of the box (1) for alternating current, its circuit (C1) receives, always connected in series and by wiring, the electro-electronic components being a current rectifier (3), an interference reducing filter (4), a switching and isolation transformer (5) that is communicant with an integrated control circuit (6) and also connected to a secondary rectifier (7), besides a secondary filter (8) communicant with the integrated control circuit (6) and also connected to a current controller (9) with three charge indicator LED-type lamps (10) having four outputs, being output 1 (11), output 2 (12), common output (13) and output to ground wire (14).

[0015] In the configuration of the box (2) for direct current, its circuit (C2) receives, always connected in series and by wiring, an over-current protector and polarity inverter (15), an interference reducing filter (16) connected to a high-frequency inductor (17) that is communicant with an integrated control circuit (18) and also connected to a current rectifier (19), besides a secondary filter (20) equally communicant with the integrated control circuit (18) and also connected to a current controller and charge indicator (21). This component (21) consists of three charge indicator LED-type lamps (22), having three outputs being output 1 (23), output 2 (24), and common output (25).

[0016] In both configurations, boxes (1) and (2), all electrical and electronic circuits are encapsulated and receive a protective layer of epoxy resin.

[0017] Thus, in the case of work where there is only power from the electrical grid, the box (1) will work through the circuit (C1) which must be grounded through the output to ground wire (14) then being connected to that of the electrical grid and to the metal surface to be treated. In this configuration, the box (1) is especially useful in homes (110/220V), for treatment in appliance surfaces such as refrigerators, freezers, stoves, washing machines, etc., gates, railings, solar heating devices, air conditioning and others. It can be used in industrial environments (110/220V) to all kinds of machinery such as boilers, lathes, rolling mills, pipelines, pipes, tools of any kind and devices with metallic properties. The same applies to large equipment/projects (including solar powered), as structure of civil constructions, bridges, containers, ships, oil platforms, wind towers, transmission of phone signals, electricity, etc. Being so ready for use through the rectifier (3) of the circuit (C1), the alternating current is converted into low voltage direct current, having reduced magnetic interferences through the reducing filter (4). Then, the switching and isolation transformer (5), working with the integrated control circuit (6) converts high voltage direct current (150350V) into high frequency alternating current (200 hz) and low voltage (near 2V), with pulse width control and over-current protection, over voltage, under current, under voltage and voltage stabilization and electron flow in the output. It also makes the isolation of the electrical grid with the output (14). In the next stage, rectifying by the secondary rectifier (7) is performed and then the high frequency filtering by the secondary filter (8). Finally, the output current flow control is indicated in the circuit (9), the LEDs (10), being one for each output (11) and (12) and (13), which when lit indicate warning signal, i.e. they warn that the respective output is not connected or energized and that the equipment is not working properly.

[0018] In the case of work where there is no power supply from the electrical grid available, the box (2) can be used from direct current originated from batteries, whatever these are, with voltage between 9 and 30V, when, by its circuit (C2) should be connected to the battery and to the metal surface to be treated. Under these conditions, the box (2) connected to the vehicle battery, acts for the treatment of light automotive structure, bodywork, radiator, engine block, braking wheels, exhaust and other points.

[0019] In heavy automotive, it can be used in the treatment of trucks, buses, heavy and agricultural machines, power generators, high-performance equipment, and vehicles of electrical charges between 12 and 24V, and when connected to the motorcycle battery, for treatment of all the metal frame, wheels, chains, exhaust, etc. After being powered from the battery, the incoming current in the circuit (C2) of the box (2) suffers action of the over-current protector and polarity inverter (15), going through the interference reducing filter (16). Then the current goes through the high-frequency inductor (17) working with the integrated switching control circuit (18) which converts the battery voltage from 9 to 30 Vdc into high-frequency alternating current, 200 Khz and low voltage, near 2V. In the next stage, the current goes through the rectifier (19) and high-frequency filtering by means of the secondary filter (20) that is also connected to the integrated switching circuit (18) for reducing magnetic interference emission. Finally, the current is passed by the current control circuit and charge indicator (21), whose LEDs (22) when lit indicate by the outputs (23), (24) and (25), warning signal, i.e. they warn which respective output is not connected or energized and whether the equipment is working properly. The application of epoxy resin (encapsulation) on the circuits ensures that they are shielded against adverse weather conditions and also makes them waterproof.
