技术介绍
随着电力电子技术与材料技术不断地发展,光伏机柜的效率、能量密度、响应速度和容量等不断提高。在智能电网的建设中,应用光伏机柜可以使新能源发电的电力定而可靠地并入电网,因而为了使新能源发电能为用户提供高质量的电力,光伏机柜是必不可少的,光伏机柜的发展也是势不可挡的。但是各种光伏机柜都有它自己的优势和局限,因而针对不同的应用领域与发电要求,应当使用不同的光伏机柜。光伏机柜的应用环境复杂多变,有西北部高原、高寒及风暴、沙尘的恶劣环境,也有南方高温、高湿度及台风、暴雨等恶劣环境。因此光伏机柜必须具有适应各种复杂多变的恶劣环境的能力。这就对柜体结构的散热、保温、节能、密封等设计要求很高,目前市场上并没有较理想的柜体结构,既能保证良好的散热效果,有具有较高密封等级,以能适应各种复杂多变的恶劣环境。市场上广泛使用的机柜风道都不具备自动关闭风道的功能,在严寒地区,冷空气会经散热风道进入箱体内部,增加了内部加热器的功耗,同时,外部风沙、颗粒也会经过散热风道进入柜体内部,影响柜体内部器件的正 ...
