What devices are required for special containers?

The non-live part of the box has a grounding device and is grounded as a whole. Ensure that the non-live metal parts of all electrical equipment in the box have good electrical grounding connections with the box. There is a grounding device outside the box and a grounding mark is sprayed on it. Warning slogans such as "High Voltage Danger" are set on each door of the box; the material of the box is fireproof, moisture-proof, earthquake-resistant, anti-rust, anti-low temperature, non-fading, non-fading and anti-aging. The overall life of the box is more than 15 years . The top of the box does not accumulate water and does not leak; the welding joint between the top and side edges can effectively prevent rain and pressure water spray from the outside of the box and will not rust during its lifetime. The end of the box-type transformer opens into a door (note that it is fully open), which facilitates entry of the cabinet from the end of the container. The box structure design of the outdoor box-type inverter meets the requirements for box transportation, lifting and transfer. The load-bearing strength of the box structure is designed according to the weight distribution of the inverter itself, and the internal equipment layout is reasonably allocated. The frequency converter is installed and fixed against the wall at the rear. The box itself is equipped with access doors, equipment doors and access doors for the inspection and maintenance needs of the frequency converter.

A dust-proof filter is installed inside the air inlet of the box. The filter should be easy to replace and clean, and the force on the filter should be fully considered when the air enters. The filter should be made of 304 stainless steel with a dust holding capacity of 10μm. Dust screen. The hinge of the door of the box transformer is strong enough to meet the local wind intensity requirements; measures (such as welding blocks, etc.) must be taken on the inside of the door of the box transformer (referring to the side opposite the door hinge) to prevent the door from being sucked into the container due to strong wind. The container body is designed according to the dimensions (length 9600mm × width 3000mm × height 3400mm). The side plates and top plates are made of container-specific plates, the floor is thickened, and the cross beams and floor beams are made of channel steel to ensure that the strength of the inverter container meets the load requirements of the inverter (6 tons) and maintenance personnel.

Make a flat plate within 40mm around the air duct outlet (inner and outer walls), install a 3mm thick and 50mm wide rubber sealing strip around the outside of the air duct outlet, and make a wind shield on the outside of the box (specific openings The dimensions and installation location are subject to drawings). There is 80mm thick fire-retardant and insulated glass wool in the interlayer of the box, and a 12mm flame-retardant high-density environmentally friendly board is attached to the inner surface. The exterior of the box is sprayed with three layers of paint, zinc-rich primer, epoxy mica-iron intermediate paint, and topcoat of acrylic polyurethane paint, color to be determined. The box material is fire-proof (satisfying 4 hours), moisture-proof, earthquake-proof, rust-proof, low-temperature-proof, non-fading, non-fading and anti-aging. The overall life of the box is more than 20 years. ?
