The utility model relates to a power distribution cabinet. The utility model relates to a heat insulating mechanism of a distribution cabinet, which comprises a heat conducting cover and a cylinder body. The heat conducting cover comprises a cover top of a flat structure and a side wall connected below the cover top. The cylinder body comprises a heat conducting section and an insulating section. The lower end of the insulating section is sealed and connected with the cover top. The lower end of the heat conducting section is sealed and connected with a heat conducting rubber bowl, a heat conducting cover, an insulating section and a conducting section. A sealed cavity is formed between the hot section and the heat conducting rubber bowl. The sealed cavity is filled with heat conducting oil, and the inner circumference of the heat conducting section is provided with heat dissipating fins, and the heat conducting section and the heat conducting rubber bowl are enclosed in a storage tank. The storage tank is filled with heat conducting fluid, and the heat conducting rubber bowl submerges the heat dissipating fins when the heat conducting rubber bowl faces the depression in the storage tank. When the sealing cavity is sunken, the heat conducting oil is filled with a sealing cavity and the radiating fins are exposed outside the heat conducting liquid. The utility model provides a heat insulation mechanism of distribution cabinet with switchable heat insulation function, which is used to solve the problem that the existing distribution cabinet can not both heat dissipation and heat insulation.

一种配电柜隔散热机构
本技术涉及配电柜,尤其涉及一种配电柜隔散热机构。
技术介绍
配电柜(箱)分动力配电柜(箱)和照明配电柜(箱)、计量柜(箱),是配电系统的末级设备。配电柜是电动机控制中心的统称。配电柜使用在负荷比较分散、回路较少的场合;电动机控制中心用于负荷集中、回路较多的场合。它们把上一级配电设备某一电路的电能分配给就近的负荷。这级设备应对负荷提供保护、监视和控制。配电柜有的使用在室内,有的使用在室外,使用室外的称为户外排队柜。户外配电柜的使用安装有以下要求:要有防雨雪措施;设围栏要有接地防护措;防潮、配电柜地脚要高于地面不小于20厘米、并铺设木板作为绝缘、配电柜底部距地面不低于1.2米;配电柜前后要留有不小于70厘米的操作空间;围栏外要设有小心触电的标示。现有的户外配电柜存在以下不足:只具有散热或隔热作用。
