Technologies Related to Intelligent Grounding Box of High-Voltage Transmission Cable

Abstract

Abstract The high-voltage cable line plays an important role in the transmission of electricity in the city network. The effective grounding of the high-voltage cable is of great significance to ensure the normal operation of the cable system. There is an increasing demand for the intelligence of grounding boxes of high-voltage transmission cables. In this paper, aiming at the heating problem of the grounding box, the overall design scheme and key technology of the cable intelligent high-voltage grounding box are proposed. The intelligent high-voltage grounding box has various electrical functions of the traditional grounding box. It also has cable circulation monitoring, waterproof, fireproof, anti-theft, and alarm functions. Remote control and management of intelligent grounding boxes can be realized through GPRS.
