Distinguishing between high and low voltage power distribution cabinets can be started from the following aspects: **Voltage level** is the core, the rated voltage of the high voltage cabinet is usually above 1kV,
Distinguishing between high and low voltage power distribution cabinets can be started from the following aspects: **Voltage level** is the core, the rated voltage of the high voltage cabinet is usually above 1kV, and the low voltage cabinet is below 1kV; **Appearance and size**, the high voltage cabinet is larger, the shell is heavy, and the “high voltage danger” sign is often affixed, and the low voltage cabinet is relatively small and thin; **Installation location** is different, the high voltage cabinet is mostly in the power substation or the high voltage distribution room, and the low voltage cabinet is installed in the low voltage switch room or next to the equipment;**Functional characteristics**, the high voltage cabinet focuses on transmission control and safety protection, and the low voltage The functions of the cabinet are more complex, covering switch control, electrical energy metering and protection.
