Description

隔离开关辅助接点防护罩
㈠技术领域：本实用新型涉及电力企业中隔离开关防护罩，具体是无需设备停电，方便更换的隔离开关辅助接点防护罩。
㈡背景技术：目前，在电力行业中使用的隔离开关防护罩是一个整体圆形筒套，底部开有圆孔，二次控制电缆由此穿入，防护罩长期暴露在室外运行，易锈蚀、腐烂，二次维护时，由于防护罩固定螺栓锈蚀，造成拆卸困难，更换防护罩时，由于二次控制电缆的存在，需一次设备停电才能进行更换，而且更换时间长，工作量大。
㈢发明内容：本实用新型的目的就是对以上缺点进行改进。提出一种结构简单，无需一次设备停电，更换时间短，方便更换的隔离开关辅助接点防护罩。
本实用新型隔离开关辅助接点防护罩，具有防护罩，其特征在于：防护罩是由两个半圆筒体构成，两个半圆筒体的上部为敞口，下部设置有一个半圆筒底，筒底的中心位置设置有一个弧形凹口，每个半圆筒体的两个边沿附近至少设有一个螺孔，通过固定螺钉将两个半圆筒体连接。
本实用新型结构简单，无需一次设备停电，更换时间短，方便更换，提高工作效率，节省人力物力。
本实用新型的工作步骤：将已锈蚀隔离开关防护罩的固定螺栓旋松，竖直方向将旧防护罩沿控制电缆保护管放置地面，用铁皮剪刀剪开、拆除。将新的防护罩装上即可。
㈣附图说明:
图1是本实用新型结构示意图;
图2是本实用新型的俯视图；
图3是单个防护罩结构示意图。
图中，1-筒体，2-筒底，3-螺孔，4-螺钉，5-弧形凹口。
㈤具体实施方式：
参见图1图2图3制作两个半圆筒体1，两个半圆筒体1的上部为敞口，下部设置有一个半圆筒底2，筒底2的中心位置设置有一个弧形凹口5，每个半圆筒体的两个边沿附近至少设有一个螺孔3，通过固定螺钉4将两个半圆筒体连接。
