In recent years, smart cities, industry, and life have flourished; As a manufacturer of sheet metal chassis and cabinets, the boxes and cabinets produced for the market need to be designed according to the environment. Different environments can easily have various impacts on electrical equipment cabinets. The environmental types in which electrical equipment is located are diverse, which can be roughly divided into natural environments, industrial environments, and some special types of environments.

在自然界環(huán)境當(dāng)中，空氣濕度、沙塵暴情況、大氣的氣壓、溫度等等都會(huì)對其產(chǎn)生影響。以我國的大港油田為例，該油田所處的維度所對應(yīng)的氣候是暖溫帶。根據(jù)我國大陸性氣候的特征，大港油田的自然環(huán)境表現(xiàn)為四季分明，溫度中等，年降水量夏多冬少，夏天會(huì)出現(xiàn)水澇、春天會(huì)出現(xiàn)春旱等現(xiàn)象。在這樣的情況下，需要對電氣設(shè)備的元器件、外殼的材料都進(jìn)行設(shè)計(jì)，用以防止周邊自然環(huán)境對其帶來的影響。

In the natural environment, air humidity, sandstorm conditions, atmospheric pressure, temperature, and so on can all have an impact on it. Taking Dagang Oilfield in China as an example, the climate corresponding to the dimension of the oilfield is warm temperate zone. According to the characteristics of China's continental climate, the natural environment of Dagang Oilfield is characterized by four distinct seasons, moderate temperature, more annual precipitation in summer and less in winter, water logging in summer, and spring drought in spring. In such cases, it is necessary to design the components and casing materials of electrical equipment to prevent the impact of the surrounding natural environment.

機(jī)箱機(jī)柜環(huán)境的設(shè)計(jì)

Design of chassis and cabinet environment

對于電氣機(jī)柜材料的選擇，要能夠與周邊溫度、濕度、干燥程度等等指標(biāo)相互吻合，使其能夠適應(yīng)自然界環(huán)境的變化。在正常情況下，電氣機(jī)柜對周邊環(huán)境的溫度是低于55攝氏度，的平均溫度不能夠超出35攝氏度，溫度低不能夠低于零下10攝氏度；對于大氣濕度的要求，必須保持在20%80%之間，不能夠產(chǎn)生凝露的現(xiàn)象。若是該電氣機(jī)柜是安裝在室內(nèi)的環(huán)境當(dāng)中，必須保證周邊環(huán)境的干凈、清潔，不會(huì)出現(xiàn)任何的導(dǎo)電現(xiàn)象，不會(huì)產(chǎn)生劇烈的晃動(dòng)與碰撞。若是周圍的環(huán)境無法達(dá)到工作指標(biāo)的要求，就需要及時(shí)與用戶進(jìn)行溝通，進(jìn)行重新設(shè)計(jì)。在一些特殊的環(huán)境當(dāng)中，比如海邊，機(jī)柜的材料設(shè)置要能夠保證其有較強(qiáng)的抗鹽霧的腐蝕能力。

The selection of electrical cabinet materials should be consistent with the surrounding temperature, humidity, dryness, and other indicators to adapt to changes in the natural environment. Under normal circumstances, the temperature of the electrical cabinet to the surrounding environment is below 55 degrees Celsius, and the average temperature of a day cannot exceed 35 degrees Celsius, with a minimum temperature of -10 degrees Celsius; The requirement for atmospheric humidity must be maintained between 20% and 80%, and condensation must not occur. If the electrical cabinet is installed in an indoor environment, it is necessary to ensure that the surrounding environment is clean and free from any conductive phenomena, as well as violent shaking and collision. If the surrounding environment cannot meet the requirements of work indicators, it is necessary to communicate with users in a timely manner and redesign. In some special environments, such as the seaside, the material settings of the cabinet should be able to ensure its strong resistance to salt spray corrosion.

對于機(jī)柜的防水功能設(shè)計(jì)，主要從機(jī)柜的整體結(jié)構(gòu)加以改進(jìn)。比如在機(jī)柜外部結(jié)構(gòu)的接縫處要能用密封膠條給它粘貼住，同時(shí)該密封膠條的選擇要能夠抵制高溫、氧化環(huán)境對其產(chǎn)生的影響，在電氣機(jī)柜的通風(fēng)口處，加入濾網(wǎng)，能夠過濾到更多的灰塵，達(dá)到了防塵的效果。

The waterproof function design of the cabinet is mainly improved from the overall structure of the cabinet. For example, at the joint of the external structure of the cabinet, a sealing tape should be used to stick it, and the selection of the sealing tape should be able to resist the impact of high temperature and oxidation environment on it. At the vent of the electrical cabinet, a filter should be added to filter more dust, achieving a dustproof effect.

電控柜的環(huán)境要求

Environmental requirements for electric control cabinets

1、環(huán)境溫度：要求在－10℃～40℃的范圍內(nèi),如果環(huán)境溫度為40℃～50℃,就采取強(qiáng)制通風(fēng)措施,以利散熱；2、相對濕度：在環(huán)境溫度為40℃時(shí)度不超過50％RH，在環(huán)境溫度為20℃時(shí)度不超過90％RH；3、空氣條件：空氣中不得含有過量塵埃、酸鹽、有腐蝕性、導(dǎo)電性、爆炸性氣體； 電力電控柜是按電氣接線要求將開關(guān)設(shè)備、測量儀表、保護(hù)電器和輔助設(shè)備組裝在封閉空間內(nèi)的金屬柜，其內(nèi)設(shè)備必須要保持在一定的溫度和濕度環(huán)境下運(yùn)行才可靠，一旦機(jī)柜內(nèi)出現(xiàn)設(shè)備故障或機(jī)房空調(diào)停止運(yùn)行，電控柜溫度會(huì)很高，環(huán)境溫度出現(xiàn)異常，會(huì)影響到設(shè)備的正常工作，進(jìn)而影響到機(jī)房業(yè)務(wù)的正常運(yùn)轉(zhuǎn)，所以你需要機(jī)房電力電控柜環(huán)境溫濕度解決方案

1. Environmental temperature: It is required to be within the range of -10 ℃ to 40 ℃. If the environmental temperature is between 40 ℃ to 50 ℃, forced ventilation measures should be taken to facilitate heat dissipation; 2. Relative humidity: not exceeding 50% RH at an ambient temperature of 40 ℃, and not exceeding 90% RH at an ambient temperature of 20 ℃; 3. Air conditions: The air must not contain excessive dust, acid salts, corrosive, conductive, or explosive gases; The power control cabinet is a metal cabinet that assembles switchgear, measuring instruments, protective appliances, and auxiliary equipment in a closed space according to electrical wiring requirements. The equipment inside the cabinet must be maintained in a certain temperature and humidity environment to operate reliably. In the event of equipment failure in the cabinet or the shutdown of the computer room air conditioning, the temperature of the control cabinet will be very high, and any abnormal environmental temperature will affect the normal operation of the equipment, This will further affect the normal operation of the computer room business, so you need a solution for the environmental temperature and humidity of the power control cabinet in the computer room
