内江干式变压器：配电用GIT制造工艺

配电用GIT制造工艺 　　
线圈绕制需要在洁净室内，要对其尺寸、匝数以及使用的绝缘材料加以监控，防止杂物混入。在绕线机上应有排除杂物的装置.加工后对线圈按一定收缩率加以紧固并检查其变形程度。铁心不应有毛刺存在。焊接时控制其变形，然后除去杂物，表面处理精加工.对绝缘垫块、管件、板件，按尺寸加工，磨边，使其光滑。对焊缝质量要求特别严.器身吊入箱壳前，要检查有关尺寸，清除杂物。装上真空有载分接内江干式变压器，充入SF6气体，要控制其露点温度。
例行试验项目有绕组直流电阻测定、绝缘电阻测定、电压比试验、阻抗电压测定及负载试验、空载试验、外施耐压试验、感应耐压试脸、长时耐压试脸、有级分接内江干式变压器试验PD。型式试验项目有温升试验、冲击电压试验。特殊试验项目有噪声测定、零序阻杭测定、短路试验、绕组对大地间及匝间电容测定、过渡电压测定、固有振动频率测定、冷却风扇及送风机输入功率测定、空载谐波测定及介质损耗角正切测定、气体分析试验等。

Manufacturing process with the GIT distribution

Coil winding requires clean room, to its size, number of turns and the use of insulating materials to be monitored to prevent debris mixed. Should be excluded from the winding machine debris on the device. Processed by a certain shrinkage of the coil to be tightened and checked for deformation. Core should not have glitches exist. Control the welding deformation, and then remove the debris, surface finishing. For insulation pads, fittings, plates, according to the size of machining, milling, make it smooth. Particularly strict quality requirements of the weld. Lift the body into the tank shell before, to check the size, clear the debris. Fitted with a vacuum-load tap-filled with SF6 gas, to control the dew point temperature.
Routine test project winding DC resistance measurement, insulation resistance measurement, voltage ratio test, determination of impedance voltage and load test, load test, the applied voltage test, the sensor face pressure test, pressure test long face, a level tap-test PD. Temperature rise test project type test, impulse voltage test. Special pilot project with noise measurement, determination of the zero-sequence resistance Hangzhou, short-circuit test, between the earth and turns of the 手 机：13287501888winding capacitance measured transition voltage measured natural vibration frequency of measurement, the cooling fan and blower input power determination,华盈非晶合金变压器有限公司是具备生产220KV电压等级变压器的现代化机械制造企业，公司注册资本8800万元，现有员工300余人，占地面积300余亩，公司拥有各种生产和使用设备100余台，产品工艺水平高，检测设备齐全，企业管理严格，产品质量可靠。求精务实，开拓创新，为用户提供完美的变压器解决方案，满足各层次客户的需求。主要产品有非晶合金变压器，干式变压器，SH15-M系列非晶合金变压器，非晶合金铁芯配电变压器，SCRBH15非晶合金干式变压器，SGBH15非晶合金变压器（10KV级），SCRBH15非晶合金卷铁芯干式变压器，35kv非晶干变变压器 35kv非晶油变变压器，超强过载能力变压器、电力变压器、油浸式变压器、矿用变压器、整流变压器、电炉变压器、特种变压器、等等，并提供新能源发电的升压及并网解决方案。我公司除生产以上10多个系列200多个品种，600多种规格的变压器外，还向用户提供非标特种产品的设计、制造。以上产品符合GB1094、GB/T6451、GB6450标准和等效IEC（国际电工委员会）标准。 measurement and media load harmonic loss tangent measurement, gas analysis testing.
