一种变压器压力释放阀防雨罩
本技术涉及变压器压力释放阀领域,具体涉及一种变压器压力释放阀防雨罩。
技术介绍
现在电力系统中的变压器压力释放阀由于厂家和型号参差不齐,使变压器压力释放阀的结构各有不同。部分厂家的压力释放阀由于密封结构设计不甚合理,电力变压器长期在户外日晒雨淋的恶劣工况下运行,会导致压力释放阀内部进水,使内部元件(如:辅助接点)锈蚀损坏,导致压力释放阀不发信号或乱发信号,影响了电力系统的安全运行。这一情况发生的原因是压力释放阀非电量信号线引出后一般安装在橡胶管中引至主变信号端子箱,由于压力释放阀一般不设置防雨设备且橡胶管易老化,所以导致户外主变的压力释放阀在阴雨天气容易误发信。
技术实现思路
针对现有技术存在的问题,本技术提供了一种变压器压力释放阀防雨罩。具体技术方案如下:一种变压器压力释放阀防雨罩,包括透明钢化玻璃制成的内罩体和透明钢化玻璃制成的外罩体,所述内罩体为长方壳体且罩设于变压器压力释放阀外,所述外罩体罩设在所述内罩体外,且所述外罩体的顶面四边为向内弯折的圆弧状,所述外罩体顶面中央开设有观察窗口,且所述观察窗口上方通过紧固螺栓可拆卸固定有向下弯折的钢化玻璃弧形透明窗,所述外罩体的顶面四边和底面四边均通过缓冲橡胶连接所述内罩体,所述外罩体的底部均匀固定有若干安装耳,所述安装耳上设置有紧固螺栓孔;优选的,所述钢化玻璃弧形透明窗的底部四周与所述外罩体相互接触的地方固定有环形的橡胶密封垫圈;优选的,所述安装耳至少为周向均匀分布的3个;优选的,固定所述钢化玻璃弧形透明窗与所述外罩体的紧固螺栓至少为周向均匀分布的3个;优选的,所述内罩体和所述外罩体的底部 ...
