Description

technical field [0001] The invention relates to the field of cable head temperature measuring devices, in particular to a temperature detection system of the cable head temperature measuring device. Background technique [0002] High-voltage transmission cables are distributed in substations and transmission lines. Due to the influence of processing technology, construction quality, operating conditions and operating environment, the failure rate of cables and cable joints is relatively high, and the normal operation of transmission cables is directly related to the transmission and distribution network. Due to the numerous and scattered cable joints of transmission and distribution lines, it is difficult to manually inspect them. Therefore, it is of great significance to monitor the working temperature of high-voltage transmission cables and their joints. The cable head temperature measurement system is mainly used in ring network cabinets, In power transmission and distrib...

[0002] High-voltage transmission cables are distributed in substations and transmission lines. Due to the influence of processing technology, construction quality, operating conditions and operating environment, the failure rate of cables and cable joints is relatively high, and the normal operation of transmission cables is directly related to the transmission and distribution network. Due to the numerous and scattered cable joints of transmission and distribution lines, it is difficult to manually inspect them. Therefore, it is of great significance to monitor the working temperature of high-voltage transmission cables and their joints. The cable head temperature measurement system is mainly used in ring network cabinets, In power transmission and distribution fields such as substations and power line cable branches, most of the current temperature detection systems of cable head temperature measurement devices only monitor and alarm the temperature of the cable head. When the temperature of the cable head is too high for an instant, it may burn out the cable head temperature measurement The device cannot protect the temperature measuring device of the cable head, so a special temperature detection system of the temperature measuring device of the cable head is needed to solve this problem
