Description
Technical Field
The utility model relates to a built-in cable joint temperature measuring device belongs to electric power system technical field.
Background
When two sections of cables are connected together in the laying process of the power cable, cable joints are required to be used for connection according to process setting. The cable joint is composed of a copper pipe, an insulating layer outside the copper pipe, a protective layer and the like. Due to the partially uncontrollable nature of the contact points at the joint, the internal resistance at the joint may fluctuate with respect to the uniform internal resistance of the cable. If the internal resistance at the joint is too high, this can lead to elevated temperatures at the joint and, in turn, failure of the insulation and protective layers, and, more seriously, combustion.
Most of the existing cable joint temperature measuring devices are built-in with a temperature sensor, then are led out through a cable, and are led out to the joint end part through extending in an insulating layer, so that the extending mode destroys the insulativity and the waterproofness of the cable joint to a certain extent, and the cable extending in the insulating layer is influenced by the current in the cable due to the fact that the cable is too close to the cable and is long in length, and the situation of misinformation is caused. The cable type direct connection mode also causes the temperature measuring device to have a relatively large induced electromotive force, so that the phenomenon of breakdown and damage is easy to occur.
