S11 series 35kV Power Transformer






Product category: product center oil immersed transformer product description: high temperature resistance, low noise, high temperature resistance; Low noise; Maintenance free. Technical innovation points: 1. Corrugated oil tank; 2. Seven level temperature control technology to ensure safe operation; 3. Nomex Paper Insulation System; 4. High temperature resistant oil; 5. The robot is fully automatic laminating, with a full inclined 45 degree 7-step seam structure. Performance characteristics of 35kV products 1. Low loss   The iron core is made of high-quality and high permeability cold-rolled silicon steel sheet. The Swiss iron core automatic laminating machine is used for longitudinal and transverse shearing. The multi-stage fully inclined seam is fully automatic laminating. The iron core binding adopts the whole pressurization and pet tape binding process, which effectively reduces the no-load loss and no-load current of the transformer. 2. The noise of low-noise oil immersed self cooling transformer is mainly caused by the electromagnetic noise of iron core. In order to reduce the noise, our company has taken the following measures: low flux density design, high-quality high permeability silicon steel sheet, controlled by Swiss automatic laminating machine, reliable clamping and supporting measures, special damping measures; 3. The leakage free oil tank and oil conservator have passed the positive pressure and negative pressure leakage test to ensure that there will be no oil leakage during the normal operation of the product. The components are installed with flange groove structure, one-time molding, and all seals are made of high-quality one-time molding acrylic rubber parts to prevent oil leakage. 4. Strong short-circuit resistance. In order to ensure that the transformer can withstand the impact of short-circuit current, and under the condition that the rated voltage is applied on the primary side and the secondary side is completely short-circuit, it will not cause any thermal and mechanical damage under the action of short-circuit current. Therefore, our company has taken the following measures in the design and manufacture:  ( 1) The reasonable ampere turn balance of transformer coil is calculated by using semi hard copper wire( 2) The strength and rigidity of the iron core clamping parts are calculated to meet the safety requirements of the maximum short-circuit mechanical force( 3) The winding pad is densified and made of high density hard paperboard( 4) The winding adopts the reasonable structure of uniform distribution and compression of pressing blocks, with uniform assembly height and uniform stress, which ensures the anti short circuit ability( 5) Some special measures are taken to prevent the coil from deformation.
