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.

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

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.

機箱機柜環境的設計

Design of chassis and cabinet environment

對于電氣機柜材料的選擇，要能夠與周邊溫度、濕度、干燥程度等等指標相互吻合，使其能夠適應自然界環境的變化。在正常情況下，電氣機柜對周邊環境的溫度是低于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，不能夠產生凝露的現象。若是該電氣機柜是安裝在室內的環境當中，必須保證周邊環境的干凈、清潔，不會出現任何的導電現象，不會產生劇烈的晃動與碰撞。若是周圍的環境無法達到工作指標的要求，就需要及時與用戶進行溝通，進行重新設計。在一些特殊的環境當中，比如海邊，機柜的材料設置要能夠保證其有較強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.

對于機柜的防水功能設計，主要從機柜的整體結構加以改進。比如在機柜外部結構的接縫處要能用密封膠條給它粘貼住，同時該密封膠條的選擇要能夠抵制高溫、氧化環境對其產生的影響，在電氣機柜的通風口處，加入濾網，能夠過濾到更多的灰塵，達到了防塵的效果。

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.

電控柜的環境要求

Environmental requirements for electric control cabinets

1、環境溫度：要求在－10℃～40℃的范圍內,如果環境溫度為40℃～50℃,就采取強制通風措施,以利散熱；2、相對濕度：在環境溫度為40℃時度不超過50％RH，在環境溫度為20℃時度不超過90％RH；3、空氣條件：空氣中不得含有過量塵埃、酸鹽、有腐蝕性、導電性、爆炸性氣體； 電力電控柜是按電氣接線要求將開關設備、測量儀表、保護電器和輔助設備組裝在封閉空間內的金屬柜，其內設備必須要保持在一定的溫度和濕度環境下運行才可靠，一旦機柜內出現設備故障或機房空調停止運行，電控柜溫度會很高，環境溫度出現異常，會影響到設備的正常工作，進而影響到機房業務的正常運轉，所以你需要機房電力電控柜環境溫濕度解決方案

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
