DA-DB系列呼吸器(压差式） |
| 呼吸器是一种内部灌装颜色可变化显示的氧化硅（俗称：硅胶）所组装而成的透明设备。 变压器内部大量油的热收缩而导致其从外界吸入空气，空气将通过所配置的呼吸器装置吸入。 呼吸器内的硅胶可以吸收进入变压器内空气中的水分，以防止变压器油受潮。 硅胶颜色的变化指示可以从呼吸器本体上所贴标签上获得。 依据标签颜色变化指示，如内部硅胶受潮严重，呼吸器内的硅胶必须更换新的或对其进行大气中潮气的能力。 依据表3和表5，恰当地选取所需呼吸器的尺寸型号。 |

DA-DB Series HYDRAULIC AIR DEHUMIDIFIERS |
| Air dehumidifiers are transparent envelopes that contain salts of chemically pure silicon oxide (called silica gel) with coloured indicator. The air sucked inside the transformer get through these envelopes, due to the thermal contraction of the oil mass. Silica gel absorbs the moisture and prevents oil contamination. The colour variations are shown on the dehumidifier label. At this point, the salt contained in the dehumidifier must be replaced with new salt or can be regenerated. A special feature of silica gel is its capacity to absorb atmospheric humidity. To choose the correct type of dehumidifier, refer to table 3 and 5. |
