Synchronous motor stator winding fault analysis and repair process

Restored when the first conductor section, the motor windings is 2 × 2.44 × 6.9-33.67ram. Flat copper wire, the breakdown at the A-phase melt 1 / 3, C-phase melt 1 / 2. Windings affected area will be cleaned oxide, copper wire wound with damage ≠ 1.38mm gap, and then high-power electric iron melting tin solder. After the repair site on the ground with fine emery cloth to seriously reduce the conductor surface curvature and prevent corona or point discharge. With mica tape, E-glass ribbon, insulating varnishes, as repair materials, repair, breakdown of winding insulation will be stripped at the old insulation, slashing more than 120mm, the old and new lap shaved cone, cone length of 25mm, without rendering copper injury , clean the impurities in pure alcohol,[link widoczny dla zalogowanych], to be volatile after new insulation package, the package mica layer, a layer of reinforced glass ribbons under external pressure, varnished one, and repeat 4 to 5 layers, all semi-iterative processing. White epoxy glass cloth laminated sheet Phenolic interval, common thread tied around their fixed, insulating varnish covers, made after partial drying finish baking. At that time, the drought emergency, local repair is put into operation after the motor synchronous motor stator winding fault of surplus repair process (small and medium sized motor oo0.27 (3) lines. 3.2 Stator winding replacement stator bar replace all wires keeping with the original cross-section and material, like music E-class insulation level increased to F rating, and the motor for corona treatment. To save funds, we also used the local construction methods. first make bar. winding bar , pull type, complex type, rubber, around the package, anti-corona, so bake molding manufacturing processes and related testing, according to the relevant access by the collaborative process manufacturers specifications, production standards and testing requirements completed in the factory, not to repeat them here. inlay construction site, there are basically the following steps: removal of the primary coil; trough cleaning, core examination; side bar I insulated hoop inlay fixed i t take the head end of welding, insulation wrap; section I cream test paint,[link widoczny dla zalogowanych], paint grant; baking, drying the overall test}; and so on. should be done every step of the construction bit. the original force to be careful when removing the coil can not be pulled oblique core silicon l or decline notch damage; trunking wash thoroughly, before volatile cleaning agent to be embedded line-side hoop I carefully wrapped insulation; bar inlay to be careful not to part with the bar straight from the bend at the end of the insulation is abrasion, in particular \closed \all gaps and cover the surface, to ensure that post-winding adhesive poured paint into a solid whole; drying and testing should be carried out strictly in accordance with the standards and norms, as site conditions, the Yun-drying and humidity control more difficult,[link widoczny dla zalogowanych], it is difficult to achieve the desired environment, but to try to high standards. after the end of the coil winding to replace them all, for the overall acceptance test, the data in Table 1. uptake ratio reached 3.0 or above, in addition to AC voltage to meet the requirements by re-treatment, the other are a test pilot project to meet the standards. repaired, the parameters of the motor into operation indicators are normal. 4 Conclusion coil local repair processing, economical and practical, the level of the entire motor insulation failure is not very widespread deterioration of the winding can be given priority . The unit has been aging, as I aim only when the measures can not guarantee long-term operation unit,[link widoczny dla zalogowanych], should be arranged after the recovery of a major overhaul. the overall replacement of the stator windings, both troubleshooting problems, restore motor performance, save money and shorten the construction period, and motor according to the need for increased insulation levels, to improve the performance of anti-corona to expand unit capacity and so on. relatively difficult to transport large motor,[link widoczny dla zalogowanych], or the traffic is very inconvenient place, you can also use local construction methods. only about updating requirements funding for the motor 1 / 7, is a more economical repair program is worth promoting. Of course, the most thorough solution is to replace the entire electric motor, which can not only solve the problem of motor insulation, but also the complete elimination of other motor chronic disease and risk. This method, while ideal, but a one-time investment, general unit more difficult to bear. Received ,1999-O7-21 (on the next page 17) 1.7877; 8 pole winding for the stator slot leakage reactance 0.7139 ~, starting torque ratio is 2.196. The experiment, YDT132M2-6/84/2kW380V50Hz multiple of 6, the motor starting torque is very very 1.8,8 2.2, consistent with the latter. Ordinary The \ More articles related to topics：
