背景技术
电力通信作为行业性的专用通信网,是随电力系统的发展需要而逐步形成和发展的,为调度、自动化、继电保护等部门提供专业的通信支持,在电网的安全运行中起到了至关重要的作用。特别是随着智能电网的进一步发展,以光纤通信为主的电力通信在电网运行中的地位愈发重要。而光缆接续的质量则直接影响了通信质量,传统的光缆接续工艺步骤如下:光缆剥纤、接头盒支架安装固定、光纤接续、光纤热缩管加热、接头护套密封安装、接头及余缆固定,传统的这种光缆续接工艺,存在光缆熔接损耗大,时问长,工艺差,不但影响美观,还影响光缆的运行质量等问题。

所述步骤3裸纤清洁工序中,观察光纤剥除部分的涂覆层是否全部剥除,若有残留,应重新剥除;如有极少量不易剥除的涂覆层,用脱脂棉球沾适量酒精,一边浸渍,一边逐步擦除。
所述步骤3裸纤切割工序中,首先要清洁切刀和调整切刀位置,切刀的摆放要平稳,切割时,动作要自然、平稳、勿重、勿急,避免断纤、斜角、毛刺及裂痕等不良端面的产生;合理分配和使用自己的右手手指,使之与切口的具体部件相对应、协调,提高切割速度和质量。

具体实施方式
本发明的光缆接续方法,包括以下步骤:
(1)用卷尺量出1.2m的光缆,并在端面用胶带进行缠绕(以避免剪除地线线股时,OPGW线股松散);
(2)在1.2m处用电缆刀环切,再横切大约30cm左右并用斜口钳除掉光缆外护层,割断纺纶纱(留出20cm),再除去光缆内护层,大约20cm左右,剪断中心加强元件和填充物后,再用光纤拔皮钳除去光纤保护管(留出15cm左右),最后用纸巾擦掉光纤外的油质物;当一人剥缆时,另一人同时进行光缆接头盒、光缆熔接设备和熔接所要用到的工具、材料的准备工作;
熔接测试设备:光纤熔接机、光时域反射仪(OTDR)。
熔接常用装备:帐篷、工作台、板凳、备用电源
熔接用工器具:断线钳、不锈钢管割刀、卷尺、光纤切割刀、剪刀、斜口钳、工具箱等;
熔接用材料:热缩套管、PVC胶带、密封胶、纯酒精、手套、卫生纸、号码管等;
(3)规范纤芯接续的工艺:
A、将光纤盘放盘纤盘内,以盘2圈为宜,多余部分可剪除。
B、光纤端面制备前先将一侧光缆的光纤穿入热缩套管。
C、光纤涂覆层的剥除
光纤涂覆层的剥除,要掌握平、稳、快三字剥纤法。“平”,即持纤要平。左手拇指和食指捏紧光纤,使之成水平状,所露长度以50mm为准,余纤在无名指、小拇指之间自然打弯,以增加力度,防止打滑。“稳”,即剥纤钳要握得稳。“快”即剥纤要快,剥纤钳应与光纤垂直,上方向内倾斜一定角度,然后用钳口轻轻卡住光纤,右手随之用力,顺光纤轴向平推出去,整个过程要自然流畅,一气呵成。
D、裸纤的清洁
观察光纤剥除部分的涂覆层是否全部剥除,若有残留,应重新剥除。如有极少量不易剥除的涂覆层,可用脱脂棉球沾适量酒精,一边 浸渍,一边逐步擦除。
将脱脂棉撕成层面平整扇形小块,沾少许酒精(以两指相捏无溢出为宜),折成“V”形,夹住已剥覆的光纤,顺光纤轴向擦拭,力争一次成功,一块脱脂棉使用2~3次后要及时更换,每次要使用脱脂棉的不同部位和层面,这样即可提高脱脂棉利用率,又防止了光纤的二次污染。
E、裸纤的切割
首先要清洁切刀和调整切刀位置,切刀的摆放要平稳,切割时,动作要自然、平稳、勿重、勿急,避免断纤、斜角、毛刺及裂痕等不良端面的产生。合理分配和使用自己的右手手指,使之与切口的具体部件相对应、协调,提高切割速度和质量。
F、纤芯接续
熔接前根据光纤的材料和类型,设置好最佳预熔主熔电流和时间以及光纤送入量等关键参数。熔接过程中还应及时清洁熔接机“V”形槽、电极、物镜、熔接室等,随时观察熔接中有无气泡、过细、过粗、虚熔、分离等不良现象,光纤熔接后必须及时进行质量检查,即:通过显示器观察连接部位的形状和接续损耗值,及时分析产生上述不良现象的原因,采取相应的改进措施。如多次出现虚熔现象,应检查熔接的两根光纤的材料、型号是否匹配,切刀和熔接机是否被灰尘污染,并检查电极氧化状况,若均无问题则应适当提高熔接电流。
G、加强套管热缩:每熔接一芯,及时进行熔接点加强套管热缩,对熔接点进行防护。
(4)在光缆接续过程中,另一工作人员在熔接的同时,在光纤的另一端进行实时测量,发现熔接损耗超出要求时马上通知工作人员进行重新熔接,此对策保证了熔接质量。同时也比原来做法(在熔接完成后才进行测量)节省了时间。
通过根据2012年至2013年传统光缆熔接质量调查如下:
