In order to overcome the deficiencies of the prior art, the utility model provides a low-voltage withdrawable switchgear with good heat dissipation effect, reasonable structure and low production cost.

The technical solution adopted by the utility model to solve the technical problem is: a low-voltage withdrawable switch cabinet, including a cabinet frame, and a bus room, an electrical room and a cable room are arranged in the cabinet frame, and the feature is: the cabinet The body frame is a C-shaped profile. The busbar room is located above the cabinet frame. The electrical room and the cable room are located below the busbar room and are located in front and rear of the cabinet frame in turn. The electrical room is divided into multiple small rooms and installed respectively. The unit drawer is provided with double doors at the rear of the cabinet frame, and the busbar room, the electrical room and the cable room are separated by baffles.

The utility model is further configured as follows: each of the baffles is provided with a plurality of baffle air holes, and the side walls of the electrical room are provided with side plates, and the side plates are provided with a plurality of side plate air holes.

The utility model is further set as: the cabinet frame is provided with mounting holes with a modulus of 25 mm.

The utility model is further set as: the baffle plate, the support plate and the side plate are all fireproof isolation plates.

The beneficial effect of the utility model is that each supporting member on the cabinet frame is fixed by pins, the baffle plate and the cabinet frame are fixedly connected by bolts, the mechanical strength of the overall structure is high, the mechanical failure is few, and the processing precision is high. The appliance room of the utility model is divided into multiple compartments by the supporting board and the drawer partition, and the unit drawer is installed in the compartment, so the special room for the primary cable line and the secondary cable line can be separated to prevent the occurrence of electric shock and short circuit , the protection level is between IP30 and IP40, and the number of installation circuits in a single cabinet has doubled, so compared with the same type of products, the power supply and distribution capacity has doubled. In the construction of a substation with the same capacity, the construction The area can be greatly reduced, and at the same time, the whole cabinet is safe, economical, applicable, and beautiful, and is suitable for power distribution switch cabinets and MCC cabinets.

Below in conjunction with accompanying drawing, the utility model is further described.

Detailed ways

As shown in Figures 1, 2, 3, and 4, this embodiment includes a cabinet frame 1. The cabinet frame 1 is a C-shaped profile. Mounting holes are set on the cabinet frame 1 with a modulus of 25mm. Inside the cabinet frame 1 The baffle plate 2 is divided into a busbar room 11, an electrical appliance room 12 and a cable room 13. The busbar room 11 is located above the cabinet frame 1, and the electrical appliance room 12 and cable room 13 are located below the busbar room 11 and in turn at the cabinet frame 1. Front and rear, the interior of the electrical appliance room 12 is divided into 6 compartments by 5 horizontally arranged pallets 3, which are divided into the first compartment to the sixth compartment from top to bottom. The 3 drawer partitions 4 of 3 are divided into 4 compartments, and the second compartment is divided into 2 compartments by 1 drawer partition 4 perpendicular to the pallet 3, each compartment is equipped with a corresponding unit drawer 5. Wherein, each baffle plate 2 is provided with a plurality of baffle plate ventilation holes 21 , and side panels 121 are installed on both side walls of the electrical appliance room 12 , and a plurality of side panel ventilation holes 1211 are provided on the side panel 121 . The bottom of each unit drawer 5 and the compartment where it is located adopt guide rails and guide grooves to cooperate, so as to realize the withdrawable cooperation of the unit drawers 5 . In addition, the baffle plate 2, the supporting plate 3 and the side plate 121 are all fireproof isolation plates, and the rear of the cabinet frame 1 is provided with a double door 6, thereby reducing the opening space.
