一种电力高压充油互感器自动真空取油样装置及使用方法
摘要：
本发明涉及一种电力高压充油互感器自动真空取油样装置及其使用方法，包括一电力高压充油互感器，一微型真空泵、一抽真空电磁阀、一进油样电磁阀、一油位传感控制器、一取样瓶等；进油样电磁阀、抽真空电磁阀以及油位传感控制器设置于取样瓶压盖上；取油样连管连接互感器放油阀与进油样电磁阀；抽真空连管连接微型真空泵与抽真空电磁阀；油位传感控制器分别与微型真空泵、进油样电磁阀以及抽真空电磁阀电性连接。本发明实现了对电力高压充油互感器全过程的真空密封取油样工作，并能在取油样完成后自动控制抽真空装置和阀门的关闭，避免电力高压充油互感器在取油样过程中外界潮气、空气和杂质的侵入，有力保障电力高压充油互感器安全运行。
摘要（英）：

The invention relates to an automatic vacuum oil sampling device for an electric high-voltage oil-filled mutual inductor and a using method thereof. The automatic vacuum oil sampling device comprises the electric high-voltage oil-filled mutual inductor, a minitype vacuum pump, a vacuum pumping electromagnetic valve, an oil sample feeding electromagnetic valve, an oil level sensor controller, a sampling bottle and the like. The oil sample feeding electromagnetic valve, the vacuum pumping electromagnetic valve and the oil level sensor controller are arranged on a sampling bottle gland. An oil sampling connecting tube is connected with a mutual inductor oil drain valve and the oil sample feeding electromagnetic valve. A vacuum pumping connecting tube is connected with the minitype vacuum pump and the vacuum pumping electromagnetic valve. The oil level sensor controller is electrically connected with the minitype vacuum pump, the oil sample feeding electromagnetic valve and the vacuum pumping electromagnetic valve. The automatic vacuum oil sampling device completes the vacuum sealing oil sampling work of the whole process of the electric high-voltage oil-filled mutual inductor, and can automatically control the closing of a vacuum pumping device and the valves after oil sampling is completed, invasion of outside moisture, air and impurities to the electric high-voltage oil-filled mutual inductor in the oil sampling process is avoided, and the safe operation of the electric high-voltage oil-filled mutual inductor is powerfully guaranteed.
