What are the characteristics of the casing of a box type substation

The shell of a box type substation mainly has the following characteristics:
1、 Good protective performance
1. Windproof, sand proof, and rain proof
      The shell of the box type substation can effectively resist the invasion of wind, sand, and rainwater. The structure design of the shell is tight, with each part connected tightly and no obvious gaps to prevent rainwater leakage. For example, in coastal areas or northwest regions with strong sandstorms, the windproof and rainproof functions of the box type substation casing can ensure the normal operation of internal electrical equipment. Its top is usually designed with a tilt to facilitate the rapid sliding of rainwater, and the shell material itself has a certain degree of waterproofing, such as using galvanized steel plates and other materials. After special surface treatment, the waterproof performance is further enhanced.
2. Dust prevention
      In order to prevent dust from entering the interior of the box and affecting the heat dissipation and normal operation of electrical equipment, the inlet and outlet of the shell are generally equipped with dust-proof nets. These dust nets can effectively filter dust particles in the air and are easy to disassemble and clean to ensure long-term dust prevention. At the same time, the overall sealing of the shell is good, which can reduce the possibility of dust entering from other parts.
2、 Good mechanical performance
1. High strength
     The shell of a box type substation needs to have sufficient strength to withstand various external forces. It can withstand a certain degree of collision and compression without easily deforming. For example, box type substations installed near roadsides or parking lots that may be subject to accidental vehicle collisions have a casing that can resist certain impact forces and protect the safety of internal equipment. The shell material is generally made of metal material (such as steel plate), which is improved in overall strength through reasonable structural design (such as adding reinforcing ribs).
2. Good seismic performance
     In order to adapt to different geological conditions and environments, the shell of the box type substation has good seismic performance. During natural disasters such as earthquakes, it can reduce damage to internal electrical equipment. The seismic design of the shell includes the use of seismic brackets to fix internal equipment, as well as the structural optimization of the shell itself, so that it can maintain stability under a certain degree of seismic wave action. For example, in earthquake prone areas, the shell design of box type substations will be specially calculated and tested according to local seismic requirements to ensure that their seismic performance meets the standards.
3、 Excellent thermal insulation performance
1. Thermal insulation
     The shell has good insulation performance, which can reduce the heat exchange inside and outside the box. This is particularly important for box type substations used in cold regions, as it can prevent the temperature of internal electrical equipment from being too low and affecting performance. Thermal insulation materials are usually used to fill the interlayer of the shell, such as polystyrene foam board, rock wool, etc. These insulation materials can effectively reduce the speed of heat conduction, keeping the temperature inside the box within a relatively stable range, which is beneficial for the normal operation of electrical equipment.
2. Thermal insulation
     In hot areas, the insulation performance of the shell can prevent external heat from entering the interior of the box, avoiding internal electrical equipment from malfunctioning due to high temperatures. For example, by applying insulation coating on the surface of the shell to reflect some of the solar radiation heat, combined with the internal insulation material, the temperature inside the box can be effectively reduced. At the same time, the ventilation design of the casing also helps with heat dissipation, allowing the hot air inside the box to be expelled in a timely manner and maintaining a suitable internal temperature.
4、 Reasonable appearance design
1. Beautiful appearance
     The design of the casing of box type substations is increasingly emphasizing aesthetics. It can be customized according to the characteristics of the surrounding environment and the needs of users, and coordinated with the surrounding buildings or landscapes. For example, the box type substation installed near urban parks or scenic spots can adopt exterior designs such as imitation wood or imitation stone to integrate into the natural environment and reduce damage to the landscape.
2. Color coordination
     The color of the shell can be selected according to different usage scenarios. In residential areas, it is common to choose colors that are in harmony with the surrounding houses, such as light blue, beige, etc; In industrial plants, more stable colors such as dark gray may be used. Moreover, the color of the shell has good durability and will not easily fade after prolonged exposure to sunlight and rain, maintaining a good appearance.
5、 Easy to install and transport
1. Easy installation
     The structural design of the casing of the box type substation is convenient for on-site installation. It is usually a prefabricated structure that can be put into use on site with simple foundation construction and equipment connections. For example, there are reserved installation holes and grounding devices at the bottom of the shell, which facilitate connection with the foundation fixing and grounding system. Moreover, the equipment installation brackets inside the casing have been pre installed, greatly reducing the workload and time of on-site installation.
2. Convenient transportation
     Due to the fact that the casing of a box type substation is generally a relatively independent box structure, it is easy to transport. It can be transported through various modes of transportation such as highways and railways. During transportation, the structure of the shell can withstand bumps and vibrations, and its size design meets transportation standards, without causing transportation difficulties due to excessive size or irregular shape.
