Research on On-line Temperature Monitoring System of Power Cable

摘要

Power cable temperature monitoring system is based on the cable installation, cable surface temperature and load current and cable thermal characteristics of the environment, the use of real-time calculation program to calculate the operating temperature of the conductor to ensure that the power cable running in a rated temperature range and to ensure The cable will not overheat and early aging conditions. Aiming at the function requirement of the on-line temperature monitoring system of the cable, the modular design method is used to divide the system design task into two functional modules, which are designed separately. However, these two functional modules are self-contained but belong to the whole system Of the sub-module.
