Remote dynamic cable group wire core temperature monitoring system

Abstract

The invention discloses a remote dynamic cable group wire core temperature monitoring system. The system comprises a distributed optical cable data comprehensive processing host, special temperature sensing optical cable devices, a data telemetering terminal module, a distribution network automation system, and three-phase current monitoring modules. The multiple special temperature sensing optical cable devices are connected with the distributed optical cable data comprehensive processing host to transmit temperature sensing results. The collected current signals are gathered to the distributed optical cable data comprehensive processing host through the multiple three-phase current monitoring modules. After the distributed optical cable data comprehensive processing host conducts data processing on the signals, the processed signals are sent to the distribution network automation system through the data telemetering terminal module so as to achieve remote dynamic monitoring of the cable group wire core temperature. By means of the remote dynamic cable group wire core temperature monitoring system, the workload in manually searching for cable overheat regions can be effectively reduced, the ability of control over the cable group temperature situation is improved, and the scheduling personnel is helped to enhance the management and control capacity on the cable group operation load.

Description

technical field [0001] The invention relates to the field of electrical engineering, in particular to a remote dynamic monitoring system for the core temperature of a cable group. Background technique [0002] With the continuous development of cities, the requirements for power supply reliability in industry, life, transportation and other fields are getting higher and higher. Compared with overhead lines, cables have become a modern city due to their high reliability and less demand for transmission corridors. The inevitable trend of the development of power channels. [0003] In recent years, there have been many accidents at home and abroad that caused the thermal collapse of the cable due to the load exceeding its actual current-carrying capacity, which proves the urgency and importance of carrying out cable temperature monitoring and current-carrying capacity management. [0004] However, in the actual site, the laying conditions of the cable group are complex and the...

Problems solved by technology

[0004] However, in the actual site, the cable group laying conditions are complex and the environmental conditions are changeable. The existing cable group core temperature management mainly adopts the method of estimating the current and applying the formula, without considering the actual situation of the site, and there is still a lack of remote dynamic monitoring methods.
