用于使用在有爆炸危险的区域中的电池运行的鼓风机过滤系统
摘要：
本发明涉及一种鼓风机过滤系统，其具有鼓风机单元(11)和蓄电池组(10)，所述鼓风机单元具有用于驱动风扇轮的电动机(24)、用于控制电动机的控制单元(27)和用于与蓄电池组连接的触点(22，23)，所述蓄电池组具有能量密度高的多个二次电池(12)和用于与鼓风机单元连接的触点(22，23)。鼓风机单元(11)能够可松开地与蓄电池组(10)耦联，由此蓄电池组经由触点与鼓风机单元连接。蓄电池组(10)设有保护电路，其中保护电路包括电子部件(15，16，17，18，19，20，21，31)，所述电子部件设计用于在形成过高电流时和/或在形成过高温度时电学上断开蓄电池组的多个二次电池(12)中的至少一个。此外，将蓄电池组(10)和鼓风机单元(11)分别至少部分地浇铸在浇铸料中。
摘要（英）：

The invention relates to a blower filter system with a blower unit (11) and a battery pack (10). The blower unit has an electric motor (24) for driving a blower impeller, a control unit (27) for controlling the electric motor and contacts (22, 23) for connecting to a battery pack. The battery pack (10) has a plurality of secondary cells (12) with high energy density and contacts (22, 23) for connecting to the blower unit. The blower unit (11) can be detachably coupled to the battery pack (10), the battery pack thereby being electrically connected to the blower unit via the contacts. The battery pack (10) is provided with protective circuits, wherein the protective circuits comprise electronic components (15, 16, 17, 18, 19, 20, 21, 31) which are designed to electrically switch off at least one of the plurality of secondary cells (12) of the battery pack if excessive currents and/or excessive temperatures occur. Moreover, the battery pack (10) and the blower unit (11) are each at least partially cast in a casting compound.
