Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinets, in particular to a low-voltage draw-out switch cabinet. Background Art

[0002] Low-voltage withdrawable switchgear is widely used in many fields such as industrial production, commercial buildings, and infrastructure. It is suitable for occasions that require frequent operations or have certain special requirements for the power system. For example, in the chemical, metallurgical, and pharmaceutical industries, low-voltage withdrawable switchgear is often used because the production process has high requirements for the stability of power supply. In commercial buildings, in order to meet the changing power needs of different tenants, this type of switchgear is also used to provide flexible power distribution. In low-voltage withdrawable switchgear, magnets are usually used to control the disconnection and connection operations of the switchgear. When the magnet is activated, it generates a magnetic field that attracts the moving parts in the switchgear, causing it to disconnect or connect the circuit. When other magnets are set on the device, it will affect the normal operation of the magnets inside the switchgear.

In the utility model, after the drawer is pushed into the cabinet, the sealing plate will contact the cabinet, and the extrusion column will be inserted into the cabinet to push the pressure sensor, so that the pressure sensor generates an electrical signal, and then the electromagnet will be energized to generate suction, firmly sucking the iron block, thereby fixing the sealing plate on one side of the cabinet, fixing the drawer inside the cabinet, and preventing the drawer from sliding out of the cabinet without human operation, and finally the indicator light emits light to remind the staff to complete the fixation.

[0004] But the device still has the following defects:

When the magnetic block is in use, it is easy to affect the electronic components and magnetic components inside the switch cabinet, interfering with the normal use of the switch cabinet. Therefore, we need to propose a low-voltage withdrawable switch cabinet. Utility Model Content

When the device is used, the fan 7 is turned on, and the fan 7 draws the outside air into the air inlet slot 5. The airflow passes through the filter hole 64 on the air inlet pipe 62, and the filter hole 64 filters the airflow to prevent impurities from entering the fan 7. When the airflow passes through the impeller 66, it drives the impeller 66 to rotate. The impeller 66 drives the rotating shell 63 to rotate through the connecting rod 65. When rotating, the impurities at the filter hole 64 can be thrown out by centrifugal force to prevent the filter hole 64 from being blocked;

[0045] An installation groove 41 is provided inside the sealing plate 3, and the movable plate 42 slides inside the installation groove 41 to control the position of the limit rod 43.
