What specifications should be followed in the practical application of special containers?

The outdoor box has the functions of cooling, dehumidification, lighting, power distribution, fire fighting, emergency lighting, emergency ventilation and thermal insulation, and the quality is reliable. Ambient temperature: maximum +4℃, minimum -3℃, maximum wind speed: 35m/s, earthquake intensity: 8 degrees, pollution level: III, protection level: IP54. Basic configuration and requirements of the box, 5mm thick and 12kV insulating rubber pad is laid on the front inspection channel; Equipment such as lighting (three-proof lights), emergency lighting, travel switch, humidity, temperature, smoke alarm, heater, socket, etc. should be arranged inside the box. The secondary line should be led into the cable trench at the bottom of the box, and attention should be paid to laying hidden wires, including humidity, temperature, smoke alarm, heater and socket to the distribution box. With a distribution box, the low-voltage distribution of the whole container and the low-voltage control power supply of the inverter are completed by the distribution box. The panel of the distribution box is opened to place HMI. The specific distribution box configuration shall be subject to the drawings. The box body is provided with a manhole in the cable trench, the size of which is not less than 6mm*6mm; The manhole cover plate cannot be designed to be removable, and it needs to be fixed with the box body, and it can be opened and closed by hinges and other components. At the same time, the cover plate is clearly marked with signs such as: be careful to step on it, fall danger, etc. The non-live part of the box is provided with a grounding device, and the whole box is grounded. Ensure that the non-charged metal parts of all electrical equipment in the box have good electrical grounding connection with the box. Outside the box, there should be a grounding device, and a grounding sign should be sprayed. Warning signs such as "high voltage danger" should be set on each door of the box. The box material should have the functions of fire prevention, moisture resistance, earthquake resistance, corrosion resistance, low temperature resistance, no fading, no peeling and anti-aging, and the overall life of the box should be more than 15 years. Ensure that the top of the box body is free of water and rain; The welding position between the top and the side edge can effectively prevent the rain and pressure water spray from being outside the box body and will not rust during the service life (note: due to the negative pressure formed in the box body when the equipment is running, it is easy to get water if it is not handled properly! ）。 It is required that the end of the box transformer should be open to a door (note that it is fully open) to facilitate the cabinet to enter from the end of the container. The box structure design of outdoor box inverter meets the requirements of box transportation and lifting and transshipment. The bearing strength of box structure is designed according to the weight distribution of inverter itself, and the layout of internal equipment is reasonably distributed. The frequency converter is installed and fixed in the way that the rear part is against the wall, and the box itself is provided with an access door, an equipment door and a manhole for the maintenance and repair of the frequency converter.
