[0002] Low-voltage switchgear is suitable for power plants, petroleum, chemical industry, metallurgy, textile, high-rise buildings and other industries for power transmission, distribution and power conversion. Low-voltage switchgear is divided into two types according to the structure: fixed type and withdrawable type. The fixed type can meet the requirements of each electrical component being reliably fixed in a certain position in the cabinet; the withdrawable type is composed of a fixed cabinet and a removable device part equipped with switches and other main electrical components. The removable part should be easy to move and reliably positioned after being moved in, and drawers of the same type and specification can be reliably interchanged.

[0003] For the sake of safety in electrical work, switchgear should have the function of preventing misoperation. The existing low-voltage switchgear is set up with a shielding piece to prevent misoperation. The shielding piece needs to be opened before the next step of opening the switchgear can be performed. However, the existing structure for controlling the opening of the shielding piece is usually set to one, and there is a risk of misoperation when the shielding piece is opened alone.
