石嘴山干式变压器：石嘴山干式变压器温升试验

石嘴山干式变压器温升试验 　　
温升试验的目的，就是要确定石嘴山干式变压器各部位的温升和验证设计数据，确定其温升限值是否符邮 箱：1262980066@qq.com合标准的规定。
温升试验是型式试验项目，也是新产品定型的主要试验项目之一。对于派生产品或正常产品，由于产品工艺的重大改变，主要部件原材料的代用，出厂产品中实测损耗值超出标准，怀疑能否达到额定功率时，均要进行温升试验。试验应在额定冷却条件下进行.即气温为10—40 ℃，冷却水温不大于25 ℃。试验时要给被试石嘴山干式变压器输入总损耗，并取其标准值和实测值的较大者。当油浸式石嘴山干式变压器的油面温度连续3h内上升不超过2℃时.即认为温升已经稳定.此时即为高温升。油浸式石嘴山干式变压器通常用短路法进行，其接线图和负载试验相同，为减少试验时接线工作量，温升试验往往在负载试验后进行。先输入总损耗，直至油面温度稳定.再测量油面温升。然后降低电压，使输入总损耗等于85℃(等于绕组温升限值加上年平均温度，如油浸式石嘴山干式变压器为65℃+20 ℃)时的负载损耗，待绕组温度稳定后(约经30-45min)，测量绕组温升。如果需要做铁心的温升试验，则再做额定电压下的空载试验，直至油面温度稳定，测量铁心温升。

Temperature rise test

The purpose of the temperature rise test is to determine the transformer temperature rise and the validation of the various parts of the design data to determine the temperature rise limits in line with the provisions of the standard.
The temperature rise test is the type of pilot projects, and new products shaping one of the pilot project. Derived products or normal, due to major changes in product technology, the main components of the alternative of raw materials, manufactured products, the measured loss value exceeds the standards, can achieve the rated power is suspected to be temperature rise test. The test shall be conducted in the rated cooling conditions. Temperature of 10-40 ℃, the cooling water temperature is not greater than 25 ° C. Test give to be a total loss o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。f the transformer input, whichever is the greater of the standard and measured values??. When the surface temperature of oil-immersed transformer oil increased by not more than 2 ° C for 3h. That the temperature rise has been stable at this time is the maximum temperature rise. Oil-immersed transformer is usually short-circuit method, the wiring diagram and load test the wiring workload for reducing the test temperature rise test is often carried out after the load test. Enter the total loss, until the oil surface temperature stable measurement of oil surface temperature rise. Then reduce the voltage to the input of the total loss is equal to 85 ° C (equal to plus the annual average temperature of the winding temperature rise limits, such as oil-immersed transformer load loss of 65 ° C at +20 ° C) until the winding temperature to stabilize (about 30 -45min), measuring the winding temperature rise. If you need to do the core temperature rise test, then do the rated voltage of the load test, until the oil surface temperature stability, and measurement of core temperature rise.
