10.3 Electrical installations in battery rooms
10.3.1 Only lighting fittings may be installed in compartments
assigned solely to large vented storage batteries (see
Ch 2, Sec 11, [6.2.1]).
The associated switches are to be installed outside such
spaces.
Electric ventilator motors are to be outside ventilation ducts
and, if within 3 m of the exhaust end of the duct, they are to
be of an explosion-proof safe type. The impeller of the fan is
to be of the non-sparking type.
Overcurrent protective devices are to be installed as close
as possible to, but outside of, battery rooms.
Electrical cables other than those pertaining to the equipment
arranged in battery rooms are not permitted.
10.3.2 Electrical equipment for use in battery rooms is to
have minimum explosion group IIC and temperature class
T1.
10.3.3 Standard marine electrical equipment may be
installed in compartments assigned solely to valve-regulated
sealed storage batteries.
上面的规范提到的的outside ventilation duct 理解成 风管的端部,那么后面的3M之内是什么意思啊。风机要装在端部,那不肯定在排气端的3M之内了啊? |
