11. If maintenance is required, professional equipment must be used for repair.。

The above describes the structural requirements of the explosion-proof distribution cabinet. Below, the maintenance of the explosion-proof distribution cabinet is discussed.。

1. First, unpack the packaging of the explosion-proof distribution cabinet product. Strictly follow the information marked on the design drawings and instruction manuals, carefully verify the quantity and specifications, check for correctness, and inspect for any damage or rust conditions. Verify that the accessories and spare parts are complete and effective.。If there is damage, record the damaged locations and extent, or take photos as evidence.。

2. After unpacking, also inspect the product certificate, instruction manual, internal wiring methods, and other technical documents.。After unpacking the high-voltage distribution box, number the distribution cabinets according to the design drawings and move them one by one into the substation installation position to facilitate subsequent assembly.。

3. After placing the explosion-proof distribution cabinet on the channel steel, use thin shims to roughly level the high-voltage box. Then, using one of them as a reference, adjust the others so that the overall panel surfaces of the high-voltage switchgear are consistent and the gaps are uniform.。After fixing with nuts, maintain a gap of 2-3 mm between cabinets, and then permanently fix the cabinet to the foundation channel steel using fixing screws or welding processes.。For aesthetics, the welds should be on the inner side of the cabinet, with no fewer than 4 weld points, each 80-100 mm long.。If there are sharp areas at the welding positions or areas of the distribution cabinet that are easily contacted and may scratch people, use a grinder or fine sandpaper until no obvious prickling sensation is felt when touched by hand.。

4.LinkedWeldingBus-barGroove。The main busbar and instruments in the high-voltage switchgear are provided by the switchgear manufacturer as supporting equipment, or can be fabricated on-site according to the design drawings.。The main busway connection, the connection between the main busbar and the riser busway, and the connection between the busway and the instrument are made with screw connections. At the busway connection surfaces, power compound grease should be applied. The tightening degree of the bolts and the activation state of the connection surfaces are adjusted by using a torque wrench to tighten the anchor bolts to the specified torque value.
