我厂的WK-4型和WK-4A型挖掘机分别装备有CS-50/6和CS-100/6型油浸式变压器。该变压器在实际工作中,经常出现低压侧缺相。打开变压器端盖检查发现:是由于变压器内部低压侧输出端铜条与接线鼻子间的铜焊开焊造成的。1原因分析(1)挖掘机在工作中振动剧烈。(2)输出端铜条较硬,且与
Our WK-4 and WK-4A excavators are equipped with CS-50/6 and CS-100/6 oil-immersed transformers respectively. The transformer in the actual work, often appear on the low-voltage side of the phase loss. Open the transformer cover inspection found that: is due to the transformer internal low-voltage side of the output of copper and wiring between the nose brazing caused by welding. 1 Analysis (1) Excavator in the work of severe vibration. (2) the output of the harder copper, and with
