Description

一种可防凝露的新型户外机构箱
技术领域
本发明涉及电力系统干燥设备技术领域,具体涉及一种可防凝露的新型户外机构箱。
背景技术
目前,在国内用于端子箱、机构箱的防凝露等主要是使用干燥剂材料或在内部安装电加热器、小型空调设备等来进行防凝露。
使用各种干燥剂在端子箱里面进行防凝露,当它们的吸水到达饱和度时就要对它们进行更换,而在潮湿地方的电网企业、电信企业、电力生产企业户外各种端子箱的防凝露需求则更高,大量使用干燥剂不仅仅浪费资源,还会由于废弃干燥剂无法重复使用而对环境产生污染。
使用电加热器装置及小型空调进行防凝露和除湿需要耗费大量的能源同时还必须保证24小时通电,同时这类设备安装在户外端子箱中后故障率相对较高,故而在运行过程中需投入大量的人力物力进行运维。
因此,发明一种吸水不会达到饱和度同时还不需要使用电加热及除湿,又能够对端子箱、机构箱等防凝露等作用的设备具有很大的现实和积极意义。
发明内容
本发明所要解决的技术问题是:提供一种可防凝露的新型户外机构箱,以解决上述使用干燥剂达到饱和度后需要更换而不断的产生经济成本,达到饱和度而废弃的干燥剂给环境带来的破坏和污染,同时在使用电加热装置消耗能源维护成本高等弊病。
为解决上述问题,本发明提供了如下技术方案:
一种可防凝露的新型户外机构箱,它包括结构箱的箱体;在箱体的内壁上顶面位置处安装有辅助凹板;辅助凹板上凹陷区域的内部通过设置栅格板组划分为若干个网格块;在该网格块中安装有使用微孔陶瓷制作的陶瓷片。
辅助凹板的内底部与栅格板组的相对端面之间的距离不低于1cm;且辅助凹板与箱体之间通过设置凝胶层进行密封。
在栅格板组上还设置有能够托住陶瓷片的网格层。
在辅助凹板的内底部还安装有定位柱;定位柱穿过栅格板组上的栅格孔设置;在陶瓷片上设置有与定位柱相配合的通孔;在定位柱的下底部还设置有卡头;卡头将陶瓷片可拆卸地固定在定位柱上。
在定位柱的下底部沿其轴线方向开有内螺纹段,卡头包括能够设置与该内螺纹段相配合的螺杆,在螺杆的端头位置还设置有橡胶垫圈。
定位柱为台阶轴结构,其大台阶端设置在辅助凹板上,该大台阶端与辅助凹板之间还设置有加强肋板, 且在大台阶端的外侧壁上开有引流槽。
栅格板组厚度不超过陶瓷片厚度的一半,且每个陶瓷片与所在栅格板组网格块的侧壁之间的距离大小不低于0.5cm
陶瓷片为使用氧化铝、氧化铁、硅、电气石、麦饭石、石灰石和陶土经过球磨粉碎后制得混合料,并在900~1300℃的温度下烧结制成的片状微孔陶瓷。
进一步的,单个陶瓷片的体积大小在180~240cm3之间;且箱体的体积所对应的单位立方米所使用陶瓷片的数目不少于150片。
优选的,陶瓷片6在栅格板组2的网格块上呈隔位设置。
本发明有益效果:
本发明针对现有户外机构箱在防凝露方面所存在的不足对常规机构箱的箱体结构进行了改造,其采用了微孔陶瓷作为吸水材料,并将其通过辅助凸板、栅格板组等装置安装在了箱体的内部;经过改造后当箱体内部的空气湿度大于微孔陶瓷片材料的湿度时,微孔陶瓷片材料会自动吸收空气中的水分并能直接吸收因凝露而形成的水,而当箱体内的空气湿度小于微孔陶瓷片的含水量时,微孔陶瓷片会自动将部分水分解成气体、离子态和小分子态的水释放出来,调节屏柜里面的空气相对湿度及消除凝露的目的,同时箱体内部加热器可取消或无需投入运行,可节省大量的电能损耗。
附图说明
图1是本实施例中发明装置的结构示意图;
图2是本实施例中将陶瓷片向辅助凹板中进行安装时的安装示意图;
图3是辅助凹板部分的截面示意图;
附图标记说明:1、箱体,2、辅助凹板,3、栅格板组,4、定位柱,5、卡头,5A、螺杆,5B、橡胶垫圈,6、陶瓷片,7、网格层。
具体实施方式
下面结合附图及具体的实施例对本发明进行进一步介绍:
实施例:
参照图1,本实施例提供一种可防凝露的新型户外机构箱,它包括结构箱的箱体1;在箱体1的内壁上顶面位置处安装有辅助凹板2;辅助凹板2上凹陷区域的内部通过设置栅格板组3划分为若干个网格块;在该网格块中安装有使用微孔陶瓷制作的陶瓷片6。
辅助凹板2的内底部与栅格板组3的相对端面之间的距离不低于1cm;且辅助凹板2与箱体1之间通过设置凝胶层进行密封。对辅助凹板2与箱体之间进行密封的目的是为了防止水汽进入两者缝隙间,对连接构件造成影响。
在栅格板组3上还设置有能够托住陶瓷片6的网格层7。本实施例中的网格层7可以考虑使用不锈钢网这种耐化学腐蚀,物理性质稳定的结构,使用网格层是为了在上方限制陶瓷片6的位置,同时能够保证陶瓷片上方与空气相接触。
在辅助凹板2的内底部还安装有定位柱4;定位柱4穿过栅格板组3上的栅格孔设置;在陶瓷片6上设置有与定位柱4相配合的通孔;在定位柱4的下底部还设置有卡头5;卡头5将陶瓷片6可拆卸地固定在定位柱4上。
在定位柱4的下底部沿其轴线方向开有内螺纹段,卡头5包括能够设置与该内螺纹段相配合的螺杆5A,在螺杆5A的端头位置还设置有橡胶垫圈5B。
定位柱4为台阶轴结构,其大台阶端设置在辅助凹板2上,该大台阶端与辅助凹板2之间还设置有加强肋板, 且在大台阶端的外侧壁上开有引流槽。
栅格板组3厚度不超过陶瓷片6厚度的一半,且每个陶瓷片6与所在栅格板组3网格块的侧壁之间的距离大小不低于0.5cm
在本实施例中,进一步释放了陶瓷片6与栅格板组3,陶瓷片6与辅助凹板2之间的间隙,允许水汽进入到陶瓷片6四周的空间中,从而能够提高陶瓷片6的吸水效果,同时还能保证陶瓷片各个端面的吸水均匀程度。
陶瓷片6为使用氧化铝、氧化铁、硅、电气石、麦饭石、石灰石和陶土经过球磨粉碎后制得混合料,并在900~1300℃的温度下烧结制成的片状微孔陶瓷。
单个陶瓷片6的体积大小在180~240cm3之间;且箱体1的体积所对应的单位立方米所使用陶瓷片的数目不少于150片。在本实施例中,单个陶瓷片6的尺寸为80*160*16mm,其在干燥的状态下质量为142g,吸收水分后的重量为208g;改造前箱体1的体积大小为0.2m3;在经过改造后共使用了31块陶瓷片6;能够有效吸收水分2kg,满足该户外机构箱中进行大颗粒水分及凝露的处理要求。
实施例2:
除陶瓷片6与栅格板组3的网格板为孔轴间隙配合外,其余结构与实施例1中结构相同,故此不再赘述,关于陶瓷片6的安装,本实施例中采用了陶瓷片6在栅格板组3的网格块上呈隔位设置的安装模式,这种安装模式类似于国际象棋棋盘结构,在能够保证吸水防凝的可靠性的前提下,通过这样的隔位安装能够大大降低装置重量,从而降低组件之间疲劳强度,提高使用寿命。
