摘要
Abstract
In order to effectively monitor the sealing state of power communication optical cable joint box,this paper proposes a relative humidity monitoring method based on fiber Bragg grating,which is used to effectively monitor the change of relative humidity of optical cable joint box,so as to monitor the sealing state of joint box.The Bragg grating has good humidity response characteristics after being treated with humidity sensitizing materials.Once the joint box is poorly sealed,it can well monitor the change of relative humidity inside the joint box and play an early warning role.The results show that the method can quickly respond to the change of relative humidity inside the junction box and effectively monitor the sealing state inside the junction box.At the same time,since the fiber Bragg grating is a passive device and only has a filtering effect on a specific wavelength,it has good channel stability and service transmission in a high-pressure and strong magnetic environment,and has a wide application prospect in practical engineering.关键词
