Method, device and system for determining ablation degree of buffer layer of cable

The invention provides a method, a device and a system for determining the ablation degree of a buffer layer of a cable, and the method comprises the steps: carrying out a buffer layer ablation simulation experiment in a laboratory to obtain the laboratory concentration of related characteristic gas, analyzing an obtained experimental ablation degree threshold value based on the characteristic gas concentration, converting a cable ablation degree threshold value, and determining the ablation degree of the buffer layer of the cable. And finally, determining the ablation degree of the buffer layer of the cable at the current moment by comparing the current gas concentration with the cable ablation degree threshold, thereby solving the problem that the existing scheme lacks a conversion method to obtain the grading threshold of the ablation severity of the buffer layer. 本申请提供了一种电缆的缓冲层的烧蚀程度的确定方法、装置和系统，该方法通过在实验室开展缓冲层烧蚀模拟实验得到相关的特征气体的实验室浓度，并分析得出的基于特征气体浓度的实验烧蚀程度阈值，换算出电缆烧蚀程度阈值，最后通过比较当前气体浓度和电缆烧蚀程度阈值的大小，确定电缆的缓冲层在当前时刻的烧蚀
