Abstract: The customer of the liquid-immersed transformer used in the wind turbine engine room requires the oil tank endurance test. There are many restrictions in the test according to the standard BS EN 50464—4:2007, which leads to some interference during the test. In order to achieve the same verification effect, a new test method is put forward and verified, and some problems are also found in the test process, which are put forward here for attention in future tests.
Keywords: fuel tank endurance test; new methods; question
0引言
隨著風(fēng)電行業(yè)的蓬勃發(fā)展,單臺(tái)機(jī)組容量越來越大,所需要的機(jī)艙內(nèi)配套變壓器容量和電壓等級(jí)也越來越高,由于機(jī)艙處于百米高空,要求其體積和重量越小越好,隨著容量和電壓等級(jí)的升高,目前干式變壓器已沒有了優(yōu)勢,越來越多的風(fēng)機(jī)廠家選擇液浸式變壓器作為機(jī)艙變。(剩余3549字)
