Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further illustrated:
As shown in Figure 1, Figure 2, Figure 3, Figure 4, high-power high voltage frequency conversion oil immersed type rectifier transformer, adopt two device bodies, a device height compression bonded line connects for " △ ", another device height compression bonded line connects for " Y ", and have the phase difference of 30o to realize 36 pulse waves between device body and export, three pillar type iron core 1 have employed high magnetic conduction grain oriented silicon steel sheet seven grades of seams, high-voltage connection 5 and low-voltage lead 6 adopt lead-in wire clamp structure, and high-power high voltage frequency conversion oil immersed type oil tank for rectifier transformer 8 bottom arranges reinforcement iron.
High-power high voltage frequency conversion oil immersed type rectifier transformer adopts two device bodies, each device body divides equally total capacity, one of them device is as high pressure winding △ 2, another is device height pressure winding Y3, for single transformer, every platform transformer exports 18 pulse waves, but these two transformers connected in parallel operate to transducer power unit, and " △ " connects and " Y " connect between have the phase difference of 30o, so just can be implemented as the power supply that power cell provides 36 pulse waves.The every of high-power high voltage frequency conversion oil immersed type rectifier transformer is 6 low pressure windings 4 mutually, because the voltage that each power cell requires transformer to export is as far as possible consistent, so namely transformer must ensure partly passing through impedance and must balancing of each low pressure winding 4, calculate according to software and the correlation experience adjustment size of transformer coil in the past and position, transformer partly pass through impedance unbalance rate <2%.High-power high voltage frequency conversion oil immersed type rectifier transformer is that 12 power cells are powered, the load of each power cell of system requirements needs equilibrium assignment, calculated by software and reasonably arrange the current balance type that 6 low pressure windings 4 of every phase export to reach each low-voltage coil, the waveform that such power cell exports is close to perfect.
High-power high voltage frequency conversion by the Electric Field Numerical Calculation to insulation system, wave process calculating with oil immersed type rectifier transformer, proposes rationally, optimizes, economical Main Insulation Structure of Electric, longitudinal insulating structure; By to the analytical calculation of bearing short-circuit capacity, adopt an effective measure, make transformer device structure anti-short circuit capability stronger.On the basis of satisfied insulation and heat radiation, Reasonable adjustment ampere-turn distributes, multiple design is carried out to the contrast of short circuit mechanical force and intensity, the mechanical vibration force that transformer is produced when bearing short circuit reduces as far as possible, and improve the supporting construction of coil, consider that the flakiness ratio of wire is within rational scope, the working strength of intensifier coil, improves design safety factor (DSF).Coil adopts half hard copper to come buckling of intensifier coil itself and axial strength.Rational design coil overhang insulation structure, strengthens the intensity of end pressing plate, ensures that coil reaches the axial precompression of designing requirement.Adopt major-minor pressure plate structure; With cylinder pressure compactor after one's death, fix and lock nail pressing, guaranteeing device body and stretching unshakable in one's determination.
High-power high voltage frequency conversion oil immersed type rectifier transformer three pillar type iron core 1 have employed high magnetic conduction grain oriented silicon steel sheet 7 grades of seams, adopts vibration reducing measure, devise cushion blocking at feet place unshakable in one's determination in Core Design.Oil tank of transformer devises denoising device, can effectively reduce the noise that transformer produces like this.
High-power high voltage frequency conversion oil immersed type rectifier transformer is put many lead-in wires in order according to outlet order after, the certain thickness attached insulation of bag is added at the lead-in wire of wooden piece clamping plate clamping place, by process with lead-in wire add wrap attached insulation after be placed in the middle of two wooden piece clamping plate with thick fixture, blend compounds blunt bolt is fixing.Adopt so rational lead-in wire clamp structure, ensure that lead-in wire has enough mechanical strengths.
High-power high voltage frequency conversion oil immersed type oil tank for rectifier transformer, is arranged in below case lid 8 low-voltage interface flange by reinforcement iron, in the middle of low-tension bushing 7, two ends withstand on case lid opening edge and weld, and solve the problem of the excessive insufficient strength of case lid 8 opening; Below whole case lid, be welded with again a reinforcement iron simultaneously, and welded together with last reinforcement iron, thus effectively increase the bulk strength of case lid.
