Abstract: Due to its diverse use environments, outdoor cabinets are more complex and harsher than indoor cabinets. In order to ensure that the cabinet can operate stably for a long time, various factors need to be considered comprehensively. In the structural design, it is necessary to comprehensively consider the various climatic conditions on site, consider the corrosion resistance, UV resistance, waterproof and dustproof effect and heat dissipation of the equipment shell, so as to ensure the electrical performance of the cabinet. This article discusses the key points of the structural design of the outdoor cabinet Detailed analysis, hoping to provide some reference for the structure design of outdoor cabinets.
Key Words: Outdoor cabinet; Waterproof and dustproof; Structural design; Grounding system
近年來,随着在电力系统中使用的自动化智能化电气设备越来越多,在户外运行的机柜设备随之增加,如开关柜、变频柜、通信柜、配电柜以及各种电力监测设备等。户外机柜的结构设计是否合理,将直接影响到设备的现场实际安装能否快速可靠、设备运行能否长期稳定以及后期运维能否便捷高效。追求更加合理的、实用性强、适应性好的户外柜结构设计,成为未来必然趋势。在设计户外机柜时,通常需要从使用环境、安全性、电磁兼容性、防护等级等多方面进行考虑[1]。
1环境因素对户外机柜的影响
不同的使用环境,应考虑不同的设计方案。户外环境中,影响因素多种多样,不能单一地考虑某一方面的影响,应综合考虑所有条件。
1.1 紫外线的影响
机柜长期在户外运行,长期受紫外线照射,容易造成金属表面涂层的掉色甚至剥落,可以采用电泳加特殊的户外粉墨喷涂工艺,来提高机柜防紫外线能力。……
