Abstract

一种环网柜、分线箱内窥镜，包括LED灯头，限流电阻，镜筒，鱼眼镜头，金属触头，所述镜筒为绝缘质地，卡装在箱体壁上，所述的鱼眼镜头设置在所述镜筒内，所述的LED灯头具有多个，环绕设置在所述镜筒上，它们串联后一端接箱体内火线，另一端串联所述限流电阻后再接所述金属触头，该金属触头设置在箱体外壁上，并且与箱体外壁绝缘。该内窥镜不仅可以窥探到环网柜、分线箱内部的所有结构，而且还自带照明功能，结构简单。

Description

一种环网柜、分线箱内窥镜
所属技术领域
本实用新型涉及一种电力设施配件，尤其是一种环网柜、分线箱内窥镜。
背景技术
电工在维护和检测电力设施时，经常需要窥视环网柜、分线箱的内部情况，然而，目前一般都是通过环网柜、分线箱的通风网孔直接观察的，这样其实只能看到箱内的一小部分结构，另外，当光线弱时，还需用电筒照射其内部才能看见结构，即便如此，也十分昏暗，很难满足观测需要。
发明内容
针对上述问题，本实用新型的目的在于提供一种环网柜、分线箱内窥镜，该内窥镜不仅可以窥探到箱体内的所有结构，而且还自带照明功能，结构简单。
本实用新型解决其技术问题所采用的技术方案是：该环网柜、分线箱内窥镜包括LED灯头，限流电阻，镜筒，鱼眼镜头，金属触头，所述镜筒为绝缘质地，卡装在箱体壁上，所述的鱼眼镜头设置在所述镜筒内，所述的LED灯头具有多个，环绕设置在所述镜筒上，它们串联后一端接箱体内火线，另一端串联所述限流电阻后再接所述金属触头，该金属触头设置在箱体外壁上，并且与箱体外壁绝缘。
本实用新型的有益效果是：当需要观察环网柜、分线箱内部情况时，工作人员只需将手触及金属触头，则从火线、各LED灯头、限流电阻、人体、大地组成一串联回路，各LED灯头发光，照亮箱体内部，另外，鱼眼镜头将箱体内的全部结构折射入人眼，工作人员可将箱体内部情况观察得巨细无遗。
附图说明
附图是本环网柜、分线箱内窥镜的结构示意图。
附图中：1，LED灯头；2，限流电阻；3，镜筒；4，鱼眼镜头；5，金属触头。
具体实施方式
下面结合附图和实施例对本实用新型进一步说明：
在附图所示实施例中，该环网柜、分线箱内窥镜包括LED灯头1，限流电阻2，镜筒3，鱼眼镜头4，金属触头5，所述镜筒3为绝缘质地，卡装在箱体壁上，所述的鱼眼镜头4设置在所述镜筒3内，所述的LED灯头1具有多个，环绕设置在所述镜筒3上，它们串联后一端接箱体内火线，另一端串联所述限流电阻2后再接所述金属触头5，该金属触头5设置在箱体外壁上，并且与箱体外壁绝缘。
上述的环网柜、分线箱内窥镜，所述的鱼眼镜头4由两块凹透镜组成，光线经两次发散折射后，可获得180度视角。
上述的环网柜、分线箱内窥镜，所述的金属触头5通过绝缘胶安装在箱体外壁上。
上述的环网柜、分线箱内窥镜，所述各LED灯头1、限流电阻2及人体所在串路导通时，各LED灯头1的分压等于其额定电压，人体分压小于36V。
上述的环网柜、分线箱内窥镜，当需要观察环网柜、分线箱内部情况时，工作人员只需将手触及金属触头5，则从火线、各LED灯头1、限流电阻2、人体、大地组成一串联回路，各LED灯头1发光，照亮箱体内部，另外，鱼眼镜头4将箱体内的全部结构折射入人眼，工作人员可将箱体内部情况观察得巨细无遗。
