1. One or two schemes, which are specific functional signs of high and low voltage distribution cabinets, including electrical circuits for power collection, distribution, metering and protection functions. A switchgear cabinet has a defined main loop (primary loop) scheme and an auxiliary loop (secondary loop) scheme. When the main scheme of a switchgear cabinet cannot be realized, several unit schemes can be combined.
2. The high and low voltage power distribution cabinets have certain operating procedures and mechanical or electrical interlocking mechanisms. Practice has proved that: No "five-proof" function or "five-proof function incomplete" is the main cause of electric power accidents.
3. The high and low voltage power distribution cabinet has a grounded metal casing, and its outer casing has support and protection. Therefore, it is required to have sufficient mechanical strength and rigidity to ensure the stability of the device, and no deformation occurs when a failure occurs in the cabinet. , external effects such as breaks. At the same time, it can prevent the human body from approaching the live part and touching the moving parts, preventing the influence of external factors on the internal facilities; and preventing the equipment from being accidentally impacted.
4. High and low voltage power distribution cabinets have the function of suppressing internal faults. “Internal faults” refer to faults caused by arc short circuit inside high and low voltage power distribution cabinets. Once an internal fault occurs, the arc fault is limited to the compartment.
