[0002] The withdrawable low-voltage switchgear is a complete set of equipment used for line control, protection and measurement in the power distribution system. Its characteristics are that the internal electrical equipment and instruments are installed in different drawers, and these drawers can be pulled out and inserted independently for inspection and maintenance, thereby improving the safety and convenience of operation. The drawers of the existing switchgear need to be unlocked before the drawers are pulled out. The unlocking direction is opposite to the drawer pulling direction, which is not convenient for pulling the drawers out.

[0003] After searching, the Chinese patent with the announcement number CN217642371U discloses a withdrawable low-voltage switch cabinet, which locks the drawer and the drawer compartment through the inner locking assembly, and then locks the unlocking handle and the fixed handle through the outer locking assembly to achieve two-stage locking. When the drawer needs to be pulled out, it is unlocked through the outer locking assembly, and then the fixed handle and the unlocking handle are held, and the unlocking handle is pressed. The unlocking handle disengages the locking pin from the locking hole through the inner locking assembly, and then the drawer can be pulled out. This utility model has the advantages of easy unlocking, simple structure, and convenient use.

[0004] When the above-mentioned withdrawable low-voltage switchgear is in use, it is not convenient to protect the functional equipment in the cabinet. When a functional device is short-circuited, the high current will spread rapidly along the circuit, thereby affecting other functional devices in the cabinet, increasing the risk of equipment damage and electrical fire, and the use effect is poor.
