  "textContent": "A high-voltage device box, comprising a box body (3), and a high-voltage grounding switch (5), a voltage transformer (6), a lightning arrester (10), a high-voltage isolation switch (11), and a vacuum circuit breaker (12) located in the box body (3). The box body (3) is divided into a low-pressure region and a high-pressure region by means of a partition plate (3.1); a low-voltage portion (111) of the high-voltage isolation switch (11) and a low-voltage portion (121) of the vacuum circuit breaker (12) are both mounted in the low-voltage region; the high-voltage grounding switch (5) and a high-voltage portion of the vacuum circuit breaker (12) are both mounted on one side of the partition plate (3.1) located in the high-voltage region; a high-voltage portion of the high-voltage isolation switch (11) is mounted on a bottom surface of the high-voltage region by means of a support insulator (16); the voltage transformer (6) and the lightning arrester (10) are respectively mounted on two opposite side walls of the high-voltage region; an inspection and repair cover plate (1) is provided on the upper portion of the low-pressure region, and a main top cover (2) is provided on the upper portion of the high-pressure region. The partition of the high-voltage and low-pressure regions of the high-voltage device box facilitates inspection and repair of the high-voltage devices, and the high-voltage devices employ a combined mounting mode of side wall mounting and bottom surface mounting, thereby reducing the whole size of the high-voltage device box.",
