配電箱、開關(guān)柜、戶外端子箱等小型輸變電設(shè)備中,空氣潮濕容易造成金屬體生銹腐蝕,縮短設(shè)備使用壽命。
In distribution box, switch cabinet, outdoor terminal box and other small power transmission and transformation equipment, humid air is easy to cause metal body rust and corrosion, and shorten the service life of the equipment.
密封箱體內(nèi)的絕緣距離緊湊,如果空氣太潮濕導(dǎo)致凝露,還會造成跳閘甚燒毀設(shè)備的嚴(yán)重后果。
The insulation distance in the sealed box is compact. If the air is too wet and causes condensation, it will cause serious consequences of tripping and even burning the equipment.
在我國南方沿海地區(qū)以及秦淮線周圍地區(qū),空氣水分多,用傳統(tǒng)加熱和排風(fēng)方法都難以奏效,特別是柜內(nèi)外產(chǎn)生很大的溫差或是梅雨潮濕季節(jié),會發(fā)生嚴(yán)重的結(jié)露,直接威脅到輸變電設(shè)備的運行。
In the southern coastal areas of China and the areas around Qinhuai line, the air moisture is abundant, so it is difficult to use the traditional heating and ventilation dehumidification methods. Especially in the case of large temperature difference inside and outside the cabinet or in the rainy season, serious condensation will occur, which directly threatens the safe operation of power transmission and transformation equipment.
通過大量實地勘察,我國電力運行系統(tǒng)環(huán)境普遍存在潮濕、積水問題,而這種惡劣的電氣運行環(huán)境,對電氣設(shè)備的使用壽命及電力系統(tǒng)運行環(huán)境很不利。
Through a large number of field investigation, the environment of power operation system in China is generally wet and ponding, and this kind of bad electrical operating environment is very unfavorable to the service life of electrical equipment and the operation environment of power system.
如:開關(guān)柜受潮閃爆,配電柜受潮霉變腐蝕,配電柜、配電箱內(nèi)潮濕、凝露,母線橋架電氣短路,電纜溝潮濕積水現(xiàn)象多有發(fā)生。
For example, the switch cabinet is affected by damp and flash explosion, the distribution cabinet is affected by damp and mildew corrosion, the distribution cabinet and the distribution box are wet and dewy, the bus bridge is short circuited, and the cable trench is wet and waterlogged.
怎樣才能有效的解決此類問題、使電氣運行環(huán)境達到完善狀態(tài),降低電力系統(tǒng)運行隱患?來為您解答:
How can we effectively solve such problems, make the electrical operation environment reach a perfect state, and reduce the hidden dangers of power system operation? MNS low voltage drawer cabinet is here to answer:
一、改善配電室環(huán)境。
1、 Improve the distribution room environment.
1、配電室內(nèi)嚴(yán)禁堆放雜物,做到室內(nèi)設(shè)備無積灰、油泥、地面無積塵、無積水,環(huán)境清潔整齊。
1. It is forbidden to stack sundries in the power distribution room. The indoor equipment shall be free of dust and sludge, and the ground shall be free of dust and ponding, and the environment shall be clean and tidy.
2、配電室內(nèi)照明足夠良好、通風(fēng)設(shè)備良好。
2. The lighting in the distribution room is good enough and the ventilation equipment is good.
3、配電室室內(nèi)環(huán)境溫度不應(yīng)超過40攝式度,相對濕度應(yīng)小于80%。
3. The indoor environment temperature of the distribution room should not exceed 40 ℃ and the relative humidity should be less than 80%.
4、配電室內(nèi)排水通暢,屋面、地下無滲水漏水現(xiàn)象。防蟲、防鼠設(shè)施完善。
4. The drainage in the power distribution room is unobstructed, and there is no leakage on the roof and underground. The facilities of pest control and rodent prevention are perfect.
5、配電室做防水隔層處理。
5. The distribution room shall be treated with waterproof partition.
二、安裝設(shè)備。
2、 Install dehumidification equipment.
1、機。
1. Dehumidifier.
由風(fēng)扇將潮濕空氣抽入機內(nèi),通過熱交換器,此時空氣中的水份冷凝成水珠, 變成干燥的空氣排出機外, 如此循環(huán)使室內(nèi)濕度降低。
The humid air is pumped into the unit by the fan and passed through the heat exchanger. At this time, the moisture in the air condenses into water droplets and turns into dry air to be discharged out of the unit. This circulation reduces the indoor humidity.
2、空調(diào)抽濕設(shè)備。
2. Air conditioning and dehumidification equipment.
抽濕就是利用空調(diào)的低溫冷凝作用,用空調(diào)改裝一下,冷凝器和蒸發(fā)器可以分開放在同一間屋子里,蒸發(fā)器做好集水防止二次蒸發(fā),集水容器弄個小水位開關(guān),控制個小水泵,積到一定程度就抽出排放,如果下水方便的話,直接連接到下水管道就可以了。如果需要控制室溫的話冷凝器可以裝到戶外。
Dehumidification is to use the low-temperature condensation effect of air-conditioning. Refit it with air-conditioner. The condenser and evaporator can be placed separately in the same room. The evaporator can collect water to prevent secondary evaporation. The water collecting container has a small water level switch and controls a small water pump. If it is convenient to drain water, it can be directly connected to the sewer pipe. If the room temperature needs to be controlled, the condenser can be installed outdoors.
3、在配電柜內(nèi)安裝自動裝置。
3. The automatic dehumidifier is installed in the power distribution cabinet.
自動工作,有效的將配電柜內(nèi)的濕氣排MNS低壓抽屜柜出柜外,以防止凝露。
Automatic dehumidification can effectively discharge the moisture in the distribution cabinet out of the cabinet to prevent condensation.
