Description

Technical Field

[0001] This utility model relates to a novel high-voltage cable coupler, belonging to the technical field of coal mine electrical equipment. Background Technology

[0002] High-voltage cable couplers are devices designed for rapid cable connection, ensuring safe cable connections even in environments containing explosive gases and coal dust mixtures. Designed for quick connection and disconnection without tools, high-voltage cable couplers significantly improve work efficiency and are particularly suitable for applications requiring frequent cable replacement or maintenance. In the coal industry, high-voltage cable couplers are widely used to connect mobile equipment such as mobile switchgear, mobile substations, and large electric shovels. Equipment such as coal mining machines and scraper conveyors require frequent adjustments to cable lengths as their advancing position changes. Temporary expansions or line modifications to underground power distribution systems also utilize high-voltage cable couplers to quickly reconfigure the power supply topology, adapting to changes in cable layout caused by the advancement of the coal face.

[0003] High-voltage cable couplers can quickly and safely connect and disconnect cables, reducing manual labor and power outage time, rapidly restoring production, and improving efficiency. They can also significantly improve the safety of power transmission and ensure stable equipment operation. Due to the special requirements of their working environment, high-voltage cable couplers require electrical isolation, and their detection methods are limited. With the continuous development of intelligent coal mine construction, the National Energy Administration's "Administrative Measures for the Acceptance of Intelligent Demonstration Coal Mines (Trial)" has placed higher demands on the fault diagnosis and early warning functions of power supply systems. Rapid and effective measures must be taken to detect and warn of high-voltage cable coupler faults to ensure the stability of coal mine power supply systems. Summary of the Invention
