Abstract
A multi-branching dry-type transformer for frequency conversion and speed control of an ocean platform is designed for various voltages and currents required by drilling operation of an offshore oil platform. An auxiliary side coil adopts the four-section cylinder type and is connected with an external pouring terminal plate by branching from the coil, terminals and mark numbers are matched on the terminal plate, and voltage and current output can be changed by changing connection between the terminals. The transformer comprises a primary side winding, an auxiliary side winding and an iron core, and a device body is assembled by a device body insulator and a lead and integrally arranged in a casing. The transformer has the advantages of being compact in structure, meeting the requirement for effective space of the offshore platform, being multipurpose, achieving voltage adjustment required by a drilling platform and being attractive in appearance, fireproof, fire-retardant and tight in closeness. Wiring is convenient.

Summary of the invention:
While the object of the invention is for sea petroleum platform well drilling operation, along with the demand of the required voltage and current of the intensification of drilling depth is different, and the requirement such as non-maintaining, moistureproof, fire prevention, anticorrosion and be applicable to long-term non-maintaining operation in the frequency range of 10-90Hz, provide a kind of ocean platform frequency control many shunting dry-type transformers.
For achieving the above object, the present invention adopts following technical proposals: the many shunting dry-type transformers of ocean platform frequency control, secondary coil adopts 4 cylindrical section formulas, by take out tap from coil, be connected with outside cast terminal board, on terminal board, be furnished with binding post and be furnished with label, the connection between change terminal can change the output of electric current and voltage.It comprises former limit winding (1), secondary winding (2) and (4) unshakable in one's determination.Above-mentioned former limit winding (1), the body of growing up to be a useful person is assembled by device body insulation (3) and lead-in wire (5) in secondary winding (2) and (4) unshakable in one's determination, and integral body is placed in shell (6).The lead-in wire of above-mentioned former limit winding (1) and secondary winding (2) adopts homonymy to draw.Described iron core (4) is provided with upper yoke (7) and lower yoke (8), is provided with left side post (9), center pillar (10) and the right post (11) between upper yoke (7) and lower yoke (8).On on the left side post (9), center pillar (10), the right post (11), be first set with former limit winding (1), and then suit secondary winding (2); On the two sides, front and back of upper yoke (7) and lower yoke (8), be respectively arranged with two upper clamping pieces (12) and two lower clamping pieces (13), and with screw rod and bolt, fix respectively between two.Finally pass through the connection set line of transformer, and in tap region, mix lug plate (14), secondary terminal board is mixed be flexible coupling (15), and shell (6) bottom is furnished with seal plug (16) and chute (17).Transformation by lug plate (14) position, realizes the conversion of electric current and voltage.
Beneficial effect of the present invention: 1. adopt rational loop construction, former secondary outlet terminal same side output terminal reaches compact conformation, effect attractive in appearance; 2. the effect that winding employing die casting and multipoint positioning, the little silicon steel sheet of employing magnetostriction unshakable in one's determination reach low noise, put for low innings; 3. by changing secondary outlet terminal position change voltage, reach easy-to-connect, a tractor serves several purposes effect; 4. stable performance, the difficult combustion of fire prevention, life termination are waited recoverable. be embodied in:
A, adopt the coilings in parallel of the wide Copper Foil band of many groups 40, after by welding copper bus, connect.Solve Copper Foil and made height-limited problem;
B, former secondary lead-in wire adopt homonymy to draw. and former limit lead-in wire is supported and is guided to secondary side by insulator by top unshakable in one's determination; Secondary is guided to stiff end daughter board, and by realizing 26 grades of Voltage-outputs by falling of outside lead Y-△ conversion and tap is disconnected;
C, folder adopt galvanizing by dipping, shell to adopt stainless steel, in order to avoid get rusty under ocean climate condition and corrode.
D, by with the supporting transformer saturation point that calculates of frequency converter, reasonable selection of transformer magnetic flux density unshakable in one's determination; By understanding drilling well under each tap, load, the current density of choose reasonable winding; And divide leading-out wire to guarantee the impedance of product by rational winding.
