A positioning block 204 is fixedly mounted to one side of the front panel 201, located inside the vertical plate 202. For high-voltage switchgear of different sizes and models, the live display device can be securely installed according to its hole arrangement. Referring to the hole spacing on the high-voltage switchgear, the device is precisely placed on the front panel 201, and then the front panel 201 is fixed to the corresponding position on the high-voltage switchgear. The multiple sets of mounting holes 203 in different positions greatly enhance installation flexibility, easily adapting to and achieving stable installation for various specifications of high-voltage switchgear. The positioning block 204 improves installation accuracy, making the installation process more convenient and efficient, and also providing great convenience for subsequent maintenance.

[0021] like Figures 1-5As shown, the locking assembly 3 includes a locking screw 301 that passes through the upright plate 202. The locking screw 301 passes through a mounting hole 203 on the upright plate 202. One end of the locking screw 301 is fixedly connected to an operating knob 302, which is located on the outer side of the upright plate 202. A clamping block 303 is sleeved on the outer side of the locking screw 301, which is located on the inner side of the upright plate 202.

The positioning block 204 improves installation accuracy, making the installation process more convenient and efficient, and also providing great convenience for subsequent maintenance work. The A-phase indicator 3042, B-phase indicator 3043, and C-phase indicator on the front panel 201... Lamp 3044 corresponds to phases A, B, and C in the high-voltage switchgear and can display the energized status of each phase in real time and accurately. The interlock indicator 3045 clearly shows the interlocked status, and the power indicator 3046 intuitively reflects the power status, enabling operators to quickly obtain key information and thus providing strong protection for safe operation. Insert the locking screw 301 into the positioning hole corresponding to the vertical plate 202, adjust it to the appropriate position, and rotate the operating knob 302 clockwise. The operating knob 302 drives the locking screw 301 to rotate clockwise and push it inward, while pushing the clamping block 303 forward.
