Description

一种圆筒母线包覆材料用机头 技术领域
本发明涉及一种机械部件， 特别涉及一种圆筒母线包覆材料用机头。
背景技术
高压电源用圆筒母线在使用时需要在母线外围包裹一层高压绝缘材料， 以防止母线导电 而产生触电事故。
通常， 圆筒母线是长度大于 8米、 直径大于 60毫米的铜质或铝质管材。 由于圆筒母线 的长度很长， 其直度无法保证， 弯曲度一般在 5毫米左右。 常规的包覆材料涂布设备的机头 是固定安装的， 圆筒母线在安装并固定到机头上后， 圆筒母线与机头模口位置随即固定， 在 涂布过程中无法调整圆筒母线与模口之间的相对位置， 这就造成一个问题： 一旦圆筒母线有 些许弯曲， 将会导致圆筒母线的中心与模口中心产生偏差， 从而使得涂布在圆筒母线上的绝 缘材料厚度不均。 在使用过程中， 这种绝缘材料的厚度不均会导致较薄侧的绝缘材料因承受 不了高压电而被击穿， 从而造成触电事故。
因此， 我们需要一种新的机头， 可以适用于现有的绝缘材料涂布设备上， 在使用过程中 根据圆筒母线的弯曲程度自动调节机头， 使圆筒母线中心与模口中心始终保持重合， 从而可 以在弯曲圆筒母线上均匀涂布绝缘材料， 避免因绝缘材料被击穿而产生的触电事故和地区性 工程断电事故。
