Compared with indoor diesel generator sets, container diesel generator sets have obvious advantages in terms of construction period: relatively simplified approval process, short installation cycle, short commissioning cycle and short delivery cycle, which means rapid recovery of a large amount of funds. The advantages of indoor installation are: the unit is more convenient to transport, the maintenance space is larger, and the overall impact on the environment is relatively small.

在談及目前國內(nèi)進行集裝箱式柴油機組設(shè)計時重點需要考慮哪些因素。尚啟英女士從以下四點進行了闡述。

What factors should be considered when talking about the design of container diesel units in China. Ms. Shang Qiying elaborated from the following four points.

集裝箱式柴油發(fā)電機組作為一個供電設(shè)備，就要考慮電力輸出，電纜選擇什么樣的類型，出線方式又是如何。集裝箱內(nèi)除了柴油發(fā)電機組之外還有其它的低壓配套設(shè)備，設(shè)計人員再開始設(shè)計時一定要明確這些設(shè)備的類型、供電需求等。提前預(yù)留市電容量和電力接口，以及控制電纜的借口。

As a power supply equipment, container diesel generator set must first consider power output, what type of cable to choose and how to outgoing. In addition to the diesel generator set, there are other low-voltage supporting equipment in the container. The designer must clarify the type and power supply demand of these equipment when starting the design again. Reserve the municipal capacitance, power interface and control cable in advance.

往往為了降低整體集裝箱噪音水平，同時為集裝箱做更多更好的防護，集裝箱降噪箱尺寸做得比較大，通透率就會減少。這樣做的后果就是影響整個機組的通風(fēng)和散熱。所以，集裝箱式柴發(fā)設(shè)計時一定要核算清楚整個集裝箱進排風(fēng)阻力，避免超過柴油發(fā)電機組冷卻系統(tǒng)限值。

In order to reduce the overall container noise level and provide more and better protection for the container, the size of the container noise reduction box is relatively large, and the permeability will be reduced. The consequence of this is to affect the ventilation and heat dissipation of the whole unit. Therefore, during the design of container diesel generator, the air inlet and exhaust resistance of the whole container must be calculated clearly to avoid exceeding the limit of the cooling system of diesel generator set.

一般情況下，集裝箱內(nèi)會設(shè)置一個日用油箱，日用油箱的容量不必拘泥于像安裝于室內(nèi)的柴油發(fā)電機組日用油箱1m?的限制，集裝箱式柴油發(fā)電機組設(shè)備內(nèi)部的日用油箱容量可以做的稍微大一些。

Generally, a daily oil tank will be set in the container. The capacity of the daily oil tank does not have to be limited to 1m? Like the daily oil tank of diesel generator set installed indoors? The daily oil tank capacity inside the container diesel generator set equipment can be slightly larger.

重點關(guān)注集裝箱式柴油發(fā)電機組的一些防護方面的考慮。在南方地區(qū)重點關(guān)注的是防雨，北方除了防雨還要考慮防柳絮、防雪、防寒、保暖。對于消防系統(tǒng)，用于集裝箱內(nèi)部的消防系統(tǒng)通常采用七氟丙烷滅火系統(tǒng)，消防系統(tǒng)常常還會與供油系統(tǒng)進行聯(lián)動，當(dāng)發(fā)生火警時及時發(fā)出警報，同時將日用油箱內(nèi)燃油快速排出，避免火警進一步擴散

Focus on some protection considerations of container diesel generator set. In the south, the focus is on rainproof. In the north, in addition to rainproof, catkins, snow, cold and warmth should also be considered. For the fire-fighting system, heptafluoropropane fire-fighting system is usually used for the fire-fighting system inside the container. The fire-fighting system is often linked with the oil supply system to give an alarm in time in case of fire, and quickly discharge the fuel in the daily oil tank to avoid further spread of fire
