新型自修复式充油电力电缆可有效避免故障发生

6th August, 2017, SHEFFIELD, UK - 2017年8月6日，英国谢菲尔德市

All major UK electricity operators operate a relatively small amount of fluid filled cable circuits on their distribution networks which over time, can be damaged and result in leaks. Currently Maser Technology is working with electricity operators National Grid and UK Power Networks on a ground-breaking, environmentally friendlier new technology which could result in millions of pounds of savings each year, using self-repairing polymers and resins to minimise leakage from damaged fluid filled cables.

所有主要的英国电力运营商在其电网系统中尚有少量的充油电缆线路运行，随着时间的推移，充油电缆可能存在破损与老化而导致泄漏。目前，迈射智能科技正与电力运营商National Grid和英国电力网合作开发一种开创性的环保新技术，每年可以节省数百万英镑电缆故障损失费用，其目的在于使用具有自修复功能的聚合物树脂实现对泄露快速封堵，从而避免充油电缆损坏。

This Network Innovation Allowance (NIA) funded project was developed by the Energy Innovation Centre (EIC) after the DNOs highlighted the need to find a way to minimise leakage in order to lower repair costs and reduce the amount of fluid that flows into the ground. The EIC identified Maser Technology as a potential solution provider.

该项目由西南英格兰配电网运营商(DNO)下属的能源创新中心(EIC)发起的电网创新基金(NIA)资助，项目源于DNO迫切需要找到一种方法来减少充油电缆泄漏故障，以降低维修成本和减少绝缘油排放的环保压力，通过多方比较，EIC最终选择迈射智能科技作为该项目的解决方案提供商。

Explaining how the‘self-repair’ technology works, Professor Gary Stephen from Maser Technology said: ‘Fluids are used to cool and insulate some types of electricity cables and if small holes or cracks appear in the cable sheath or joints that’s when leaks can occur. We have developed an additive that can be included in the fluid which when it comes in to contact with the air, will react and essentially plug the gap and also prevent a more major leak occur. This would then extend the life of older cables and provide improved environmental performance.’

为解释具有“自我修复”功能的充油电缆自愈技术是如何实现的，来自迈射智能科技的Gary Stephen教授说：“绝缘油被用来冷却和绝缘某些类型的电缆，如果电缆护套或接头出现小洞或裂缝，就可导致电缆泄漏的发生。为此我们已经开发了一种添加剂，它可以添加在绝缘油中，当它与空气接触时，会发生反应并固化后堵塞间隙进而有效防止更大的泄漏发生。这将延长旧电缆的使用寿命，并有效改善对环境的影响。

Jim Cardwell, Head of Trading and Innovation at Northern Powergrid, said: ‘A cable with self-repairing properties has the potential to transform the way we treat and respond to cable damage and we’re pleased to be collaborating with industry and an innovative company to trial a new solution that could make a big difference for our customers and local communities.

北部电力公司(Northern Powergrid)贸易和创新部负责人Jim Cardwell说：“一条具有自修复特性的充油电缆有可能改变我们对电缆损坏的处理和应对方式，我们很高兴与一家创新公司合作，并尝试一种新的解决方案，从而为我们的客户和当地社区带来巨大的影响。”

Ian Cooper, Senior Technology Transfer Engineer at UK Power Networks, said: ‘Cable damage is a problem that all electricity networks face and it makes sense for us to collaborate with other networks to look for a solution.’

英国电力网(UK Power Networks)高级技术工程师Ian Cooper说：“电缆损坏是所有电力网络面临的严峻考验，通过与其他技术公司的合作寻找突破性解决方案是很有意义的。”
