应发发电机和应变压器的电缆是必须走在应发室内

kun2014

规范有没有要求：应发的电缆和应变电缆必须在应发室内，现在我们有一个船电缆从应配下面走到CO2室，然后再翻上来，有关系？

这样的情况还没有见过的，不过发电机室里面见过走电缆的，上面的 问题不是很懂，还是有电气专业回答比较好

这是规范的常规要求，应急发电机至应急配电板的电缆必须在应发室内。保持其独立性。

我也碰到过这个问题，不过是船东提出来的，非要电缆采用耐火型的，不过我觉得，如果你穿过的是CO2室，假如火大到连CO2室都TM守不住了，人估计早跑了，还管什么应急发电机，，，，个人见解

3.3.3. The location of:

the emergency source of electrical power and associated transforming equipment, if any;
the transitional source of emergency power;
the emergency switchboard; and
the emergency lighting switchboard;
in relation to:

the main source of electrical power, associated transforming equipment, if any; and
the main switchboard;
is to be such as to ensure that a fire or other casualty in spaces containing:

the main source of electrical power, associated transforming equipment, if any, and the main switchboard; or
in any machinery space of Category A;
will not interfere with the supply, control and distribution of emergency electrical power.

3.3.4. The space containing:

the emergency source of electrical power, associated transforming equipment, if any;
the transitional source of emergency electrical power; and
the emergency switchboard;
is not to be contiguous to the boundaries of machinery spaces of Category A or those spaces containing:

the main source of electrical power, associated transforming equipment, if any; or
the main switchboard.
这段是摘自LR货轮规范(大于500). 里面看起来只说应急发电机,应配,应急变压器等不能与主电源设备空间和A类机械处所直接相邻,或者有"合适的"措施也可以.
所以见到很多应发电缆走CO2甚至走干货间的,这些在退审的时候也都没问题.

105 Emergency switchboard
a) The emergency switchboard shall be installed as near as is practicable to the emergency source of electrical
power. (Interpretation of SOLAS Ch. II-1/43.5.1)
.....
i) Cables between equipment installed in the emergency generator room, shall be run inside the boundary of
the room.
摘自DNV规范Pt.4 Ch.8 Sec.2.C105
应急电源及配电板的安装需要符合一个自洽的逻辑.也就是它的运行应不受任何外界因素干扰.
所以应发间的电缆必须在应发室内敷设.

看来在不同人，不同规范下并没有统一标准

你的电缆安装，不违背法规（SOLAS)或IEC关于电缆敷设的要求。可以接受。

但，要是有足够的空间在应急发电机间内部走线的话，不要穿入CO2房间又穿回应急发电机间。
