油浸式变压器的油改如何处理?

1、压力滤过法:电力变压器用的绝缘油必具有绝缘性质和导热性质(国家标准)在安装现场,常用压力滤过法完成绝缘油的一般干燥(除去水分)和净化(除去脏物)的方法。
1, pressure filtration: insulating oil for a power transformer having insulation properties and thermal conductivity (national standard) at the installation site, the commonly used pressure filtration method of insulating oil (dry moisture removal) and purification (remove dirt) method.
2、开阀门8和11,然后起动油泵,再开阀门6和7。停油时,先关闭6和7,然后停油泵,再关闭8和11的阀门。
2, open the valve 8 and 11, and then start the oil pump, and then open the valve 6 and 7. When stopping the oil, turn off 6 and 7, then stop the oil pump, then close the valves 8 and 11.
⑵正常工作时,压力表3*10 ~4*10 Pa的压力下是正常工作,如果杂质和油纸堵塞,压力增高,当压力达到6*10 Pa时,必须停止,更换滤纸。
The normal work, the pressure gauge 3*10 ~4*10 Pa under the pressure of work is normal, if the impurities and oil clogging, increased pressure, when the pressure reaches 6*10 Pa, must stop, replace the filter paper.
⑶滤纸使用前放在80-90℃烘箱内干燥24小时,放在清洁容器内。
The filter before use in 80-90 DEG C oven dry for 24 hours, placed in a clean container.
⑷滤网,每隔10~15小时清洗一次,开始时滤油3-5分钟内,出油孔通过阀门10送回污油罐重新滤过,积存滤油器内的油,通过阀门9送回污油系统,再次滤过。以上滤油要多次进行精华和干燥合格为止。
The filter, cleaned once every 10~15 hours, 3-5 minutes at the start of the oil filter, an oil hole through the valve 10 to the waste oil re filtration, accumulation of oil filter oil within the oil system, back through the valve 9, again filtration. The above filter oil should be dried and dried for many times.

3、变压器带电滤油:
3 、 transformer oil filter:
⑴当电压高于10V时,不宜采用带电滤油。因为在过滤时,产生较多的气泡,气泡在较高电压的作用下会产生游离现象,使油的绝缘性能 变坏,导致内部放电。在进行带电滤油时,定期将瓦斯继电器内从油中释放出的气体放掉。
When the voltage is higher than 10V, should not be charged by the oil filter. Because more bubbles are produced during the filtration process, the bubbles will lead to ionization at higher voltage, which will deteriorate the insulation performance of the oil and lead to internal discharge. When the oil is filtered, the gas released from the oil is periodically removed from the gas relay.
⑵带电滤油时,油管和滤油机应可靠接地,以保护工作人员的人身安全,工作人员要专业,要有人监护,穿带好绝缘用品。
The charged oil filter, oil and oil filter should be grounded, to protect the personal safety of the staff, the staff should be professional, human care, wear with insulation products.
⑶操作:4和5对角阀门接口处,接上压力式滤油扣,阀门4抽出油,从阀门5处打回油箱,经多项循环滤过,直至符合标准。
The operation: 4 and 5 diagonal valve interface, connect the pressure type oil filter button, the valve 4 extracted oil, 5 from the valve at the back to the tank, through a multi cycle filtration, until it meets the standard.
