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.

在自然界环境当中，空气湿度、沙尘暴情况、大气的气压、温度等等都会对其产生影响。以我国的大港油田为例，该油田所处的维度所对应的气候是暖温带。根据我国大陆性气候的特征，大港油田的自然环境表现为四季分明，温度中等，年降水量夏多冬少，夏天会出现水涝、春天会出现春旱等现象。在这样的情况下，需要对电气设备的元器件、外壳的材料都进行设计，用以防止周边自然环境对其带来的影响。

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.

机箱机柜环境的设计

Design of chassis and cabinet environment

对于电气机柜材料的选择，要能够与周边温度、湿度、干燥程度等等指标相互吻合，使其能够适应自然界环境的变化。在正常情况下，电气机柜对周边环境的温度是低于55摄氏度，的平均温度不能够超出35摄氏度，温度低不能够低于零下10摄氏度；对于大气湿度的要求，必须保持在20%80%之间，不能够产生凝露的现象。若是该电气机柜是安装在室内的环境当中，必须保证周边环境的干净、清洁，不会出现任何的导电现象，不会产生剧烈的晃动与碰撞。若是周围的环境无法达到工作指标的要求，就需要及时与用户进行沟通，进行重新设计。在一些特殊的环境当中，比如海边，机柜的材料设置要能够保证其有较强的抗盐雾的腐蚀能力。

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.

对于机柜的防水功能设计，主要从机柜的整体结构加以改进。比如在机柜外部结构的接缝处要能用密封胶条给它粘贴住，同时该密封胶条的选择要能够抵制高温、氧化环境对其产生的影响，在电气机柜的通风口处，加入滤网，能够过滤到更多的灰尘，达到了防尘的效果。

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.

电控柜的环境要求

Environmental requirements for electric control cabinets

1、环境温度：要求在－10℃～40℃的范围内,如果环境温度为40℃～50℃,就采取强制通风措施,以利散热；2、相对湿度：在环境温度为40℃时度不超过50％RH，在环境温度为20℃时度不超过90％RH；3、空气条件：空气中不得含有过量尘埃、酸盐、有腐蚀性、导电性、爆炸性气体； 电力电控柜是按电气接线要求将开关设备、测量仪表、保护电器和辅助设备组装在封闭空间内的金属柜，其内设备必须要保持在一定的温度和湿度环境下运行才可靠，一旦机柜内出现设备故障或机房空调停止运行，电控柜温度会很高，环境温度出现异常，会影响到设备的正常工作，进而影响到机房业务的正常运转，所以你需要机房电力电控柜环境温湿度解决方案

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
