The utility model relates to a easily sealed wall-piercing casing, which comprises a casing body, a high-pressure shielding net and a low-pressure shielding net. The features are as follows: the high-pressure shielding net is arranged in the middle side wall of the casing body, the low-pressure shielding net concentric center is arranged outside the high-pressure shielding net, the two ends of the casing body are installed with sealing rings, and the sealing ring is connected with the casing body. A groove is arranged at the junction, and a fastening device is arranged in the groove. The fastening device includes an elastic device and a compression device. The elastic device is located between the casing body and the compression device. The product improves the sealing performance of the overall structure, is easy to install, is not easy to fall off, and can be used as a buffer layer to protect the casing from being damaged, and the internal shielding device is provided. The ring can distribute the electric field evenly, prevent the bushing from being broken down by the electric field, and increase the overall safety of the product.

一种易密封的穿墙套管
本技术涉及绝缘体
,具体涉及一种易密封的穿墙套管。
技术介绍
高压穿墙套管适用于工频交流电压为35kV及以下电厂、变电站的配电装置和高压电器中,作导电部分穿过墙壁或其它接地物的绝缘和支持用。现有的穿墙套管,在组装时铜排会与套管发生碰撞,有几率损坏套管壁,且安装完毕后,穿墙套管的密封性也许会有不足之处,穿墙套管处于潮湿的空气中时,可能会使绝缘性能下降,导致发生绝缘击穿。因此,如何对现有的穿墙套管进行改进,使其克服上述问题,是本领域技术人员亟待解决的一个问题。
技术实现思路
本技术针对目前穿墙套管存在的不足,套管密封性不足,且组装时有几率会损坏套管,对其结构进行优化,提供一种易密封的穿墙套管。为了实现上述目的,本技术提供了一种新型的结构及技术方案:一种易密封的穿墙套管,包括套管本体、高压屏蔽网和低压屏蔽网,其特征在于:所述高压屏蔽网设置于所述套管本体中部侧壁内,所述低压屏蔽网同轴心设置于所述高压屏蔽网外侧,所述套管本体两端安装有密封圈,所述密封圈与所述套管本体连接处开设有凹槽,所述凹槽内设置有紧固装置,所述紧固装置包括弹力装置与压紧装置,所述弹力装 ...
