呼伦贝尔干式变压器：全密封呼伦贝尔干式变压器运行维护要点

全密封呼伦贝尔干式变压器运行维护要点 　　
目前全密封配电呼伦贝尔干式变压器使用较多，其他油浸式呼伦贝尔干式变压器.包括高损耗、低损耗(S9、新S9型等)呼伦贝尔干式变压器、非晶合金铁心呼伦贝尔干式变压器、卷铁心呼伦贝尔干式变压器、R型卷铁心呼伦贝尔干式变压器、单相呼伦贝尔干式变压器、农用呼伦贝尔干式变压器、调容量呼伦贝尔干式变压器、防雷呼伦贝尔干式变压器、低噪声呼伦贝尔干式变压器、欧式箱变、美式箱变等都属油浸式呼伦贝尔干式变压器(箱变有时用呼伦贝尔干式变压器)，其检查维护要点相同.只有全密封呼伦贝尔干式变压器和呼伦贝尔干式变压器稍有不同( SF6呼伦贝尔干式变压器因使用极少。
全密封呼伦贝尔干式变压器由于隔绝了空气与油的接触.减缓了油和绝缘纤维的老化过程，提高了呼伦贝尔干式变压器的可靠性.在安装时，一般不必吊心检查.只做常规的交接试验.并做如下检查：
1)检查油箱是否有渗漏油现象。
2）检查各密封处是否有渗漏油现象，若有渗漏，说明密封可能已经松动过，应加以旋紧处理。
3)凡有一处发生上述1)、2)所示情况，为保险起见，应进行确定油位高度的工作.方法是将箱盖上油位管的塞子缓慢打开，用干净的杠件(如长的旋具、新铅丝等)探测油面位置，油面在箱盖以上20mm者，不需要补加油；而在此以下者，应补加同型号的呼伦贝尔干式变压器油直至满油管口.再拧紧塞子，使其密封.对新型产品已设油位计的，只需监视油位计即可。
4)水银温度计、信号温度计安装时要将温度计插管内注满呼伦贝尔干式变压器油。
全密封呼伦贝尔干式变压器的运行检查除与油浸式呼伦贝尔干式变压器相同外，重点是检查渗漏油。一般情况下可不取油样。可比其他呼伦贝尔干式变压器增大一倍时间(即每6年)做一次油耐压，并检查油位和加油。

Sealed transformer operation and maintenance points

Sealed distribution transformers use more, other oil-immersed transformer, including the high华盈非晶合金变压器有限公司 loss, low loss (S9 and S9, etc.) transformers, amorphous alloy core transformer wound core transformer, R-wound core transformer, single phase transformers, agricultural transformer, adjust capacity transformers, lightning protection, transformer, low-noise transformer, Continental me change American box change, and so are oil-immersed transformer (box variable is sometimes used to dry-type transformers), the inspection and maintenance points only sealed transformers and dry type transformer is slightly different (SF6 transformer rarely use.
Sealed transformer cut off from contact with air and oil. Slow down the aging process of oil and insulation fibers, to improve the reliability of the transformer. Generally do not have hanging heart checks during installation. Only conventional handover test and make the following checks :
1) Check the tank for oil leakage phenomenon.
2) Check the seal at the oil leakage, if leakage, the seal may have been loose should be tightened processing.
3) Where one of the above 1), 2) as shown in, for insurance purposes, should be carried out to determine the oil level height of the work method is to cover oil tube plug is slow to open, clean bar (such as long screwdriver, new wire, etc.) to detect the location of the oil level, oil level does not need to fill refueling who cover more than 20mm; in this below, shall be added to the same types of transformer oil until the full mouth of tubing. then tighten stopper to seal. new products have set the oil level gauge, simply monitor the oil level gauge can be.
4) mercury thermometer, To thermometer intubation of the installation of the signal th手 机：13287501888ermometer filled with transformer oil.
Sealed transformer run a check the same as the oil-immersed transformer, the focus is to check the oil leakage. Under normal circumstances may take oil samples. Than other transformer doubling time (ie every six years) to do an oil pressure, and check the oil level and oil.
