在现代通信中,电缆线路是整个通信网中的重要组成部份,搞好市话通信电缆的各项维护工作非常重要。电缆充气维护是整个电缆维护的主要工作,通过近三十年对电缆充气维护的实践证明,电缆内常有气压存在,就能保证电缆芯线不出电气障碍。但是其中一项主要的气压监视工作,即电缆的气压测量(以下简称测压)技术一直落后,它需要维护人员每七天(规程规定)骑自行车到局外测压点的现场索取数据,以掌握所维护电缆的气压情况。这种测压的办法,既不能连续掌握电缆内气压情况,影响障碍的极早发现,又费工费时,劳动效率也低。
In modern communication, the cable line is an important part of the entire communication network. It is very important to do a good job of maintaining the local communication cables. Cable inflatable maintenance is the main work of the entire cable maintenance, through the nearly thirty years of cable inflatable maintenance practice has proved that there are often atmospheric pressure in the cable, you can ensure that the cable core is not an electrical obstacle. However, one of the major pressure monitoring tasks, that is, the pressure measurement of cables (hereinafter referred to as pressure measurement) has been lagging behind. It requires maintenance personnel to obtain data on-site by biking to off-site pressure measurement points every seven days Maintained cable pressure conditions. This measure of manometry, neither continuous grasp of the pressure inside the cable, affecting the very early detection of obstacles, but also time-consuming effort, labor efficiency is low.
