Due between transformer installation and platform clamping plate, space requirement harshness, also needs to consider establishing of transformerCount reserving of size and escape way and maintenance channel etc. Current platform frequency control dry type transformationDevice is used for the neritic province domains such as the Bohai Sea, and supporting variable-frequency motor capacity is less, and drilling depth is more shallow. BecomeThe secondary voltage gear that depressor provides is generally below 9 grades, and range of regulation is less. Along with sending out of marketExhibition, increasing offshore platform is applied to region, deep-sea, and traditional pressure regulation among a small circle, pressure regulation progression are fewPlatform be difficult to meet present drillng operation with dry-type transformer.
Summary of the invention:
While the object of the invention is for sea petroleum platform well drilling operation, along with the intensification institute of drilling depthThe demand difference of voltage and current needing, and non-maintaining, moistureproof, fire prevention, anticorrosion etc. require and fitFor long-term non-maintaining operation in the frequency range of 10-90Hz, provide a kind of ocean platform frequency conversion to adjustThe many shunting dry-type transformers of speed.
For achieving the above object, the present invention adopts following technical proposals: ocean platform frequency control is with many pointsConnect dry-type transformer, secondary coil adopts 4 cylindrical section formulas, by take out tap and outside cast end from coilDaughter board is connected, and is furnished with binding post and is furnished with label on terminal board, and the connection changing between terminal can changeThe output of time variant voltage electric current. It comprises former limit winding (1), secondary winding (2) and (4) unshakable in one's determination. Above-mentionedFormer limit winding (1), secondary winding (2) and (4) unshakable in one's determination are by device body insulation (3) and lead-in wire (5)Assemble the body of growing up to be a useful person, and entirety is placed in shell (6). Above-mentioned former limit winding (1) and secondary winding (2)Lead-in wire adopt homonymy draw. Described iron core (4) is provided with upper yoke (7) and lower yoke (8), upper ironBetween yoke (7) and lower yoke (8), be provided with left side post (9), center pillar (10) and the right post (11). On a left sideOn side column (9), center pillar (10), the right post (11), be first set with former limit winding (1), and then coverDress secondary winding (2); Two sides, front and back at upper yoke (7) and lower yoke (8) is respectively arranged with twoUpper clamping piece (12) and two lower clamping pieces (13), and fix with screw rod and bolt respectively between two. Finally pass throughThe connection set line of transformer, and mix lug plate (14) in tap region, secondary terminal board is mixed soft companyConnect (15), shell (6) bottom is furnished with seal plug (16) and chute (17). By lug plate (14)The transformation of 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 terminalReach compact conformation, effect attractive in appearance; 2. winding employing die casting and multipoint positioning, the magnetic that adopts unshakable in one's determinationCause the effect that flexible little silicon steel sheet reaches low noise, puts for low innings; 3. by changing secondary outlet terminal positionPut change voltage and reach easy-to-connect, a tractor serves several purposes effect; 4. stable performance, the difficult combustion of fire prevention, life-span are eventuallyKnot is waited recoverable. is embodied in:
A, adopt the coilings in parallel of the wide Copper Foil band of many groups 40, after connect by welding copper bus. Solve Copper FoilMake 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 by insulator by top unshakable in one's determinationSecondary side; Secondary is guided to stiff end daughter board, and by by outside lead Y-△ conversion and tapFall to break and can realize 26 grades of Voltage-outputs;
C, folder adopt galvanizing by dipping, shell to adopt stainless steel, in order to avoid under marine climate conditionGet rusty and corrode.
D, by with the supporting transformer saturation point that calculates of frequency converter, reasonable selection of transformer magnetic unshakable in one's determinationFlux density; By understanding drilling well load under each tap, the current density of choose reasonable winding; And by closingThe winding of reason divides leading-out wire to ensure the impedance of product.
