Abstract

The invention discloses an online monitoring system for a networked 10kV intelligent fast user incoming line demarcation cable branch box, comprising a main console, an information acquisition terminal, and a group consisting of a high-voltage charged sensor, a current transformer, three-phase and single-phase short-circuit current sensors, and a wireless temperature sensor that are disposed at acable tap. The information acquisition terminal obtains temperature information, a line current value, a charge state, and fault current type information, and transmits the same to the main console for storage and display through 4G communication. The online monitoring system has a high degree of functional integration, meets the requirements of the branch box for real-time and high-speed communication, and guarantees the stability, reliability, and instantaneity of data transmission.

Description

technical field [0001] The invention relates to electric power engineering technology, in particular to a cable branch box. Background technique [0002] The taps in the cable branch box are the weak link in the safe operation of the power system. Due to the influence of unfavorable factors in the production site environment and the limitation of the production process, the crimping quality of the cable tap is unreliable. After a period of high current operation, overheating and oxidation will occur at the crimping point, and the contact resistance will gradually increase. If the treatment is not timely, the temperature of the joint will further rise and the insulation will age, which will eventually lead to accidents. According to statistics, the accident rate of cable joints accounts for 90% of cable accidents. [0003] At present, the monitoring of domestic cable branch boxes is mainly through manual inspection. There are problems such as excessive or insufficient main...
