Description
Technical Field
[0001] This utility model belongs to the field of building materials technology, and in particular relates to a multi-purpose substation shielding sound-absorbing firewall panel. Background Technology
[0002] In modern architecture, wall panels serve multiple functions. They not only act as load-bearing structures but also provide insulation, moisture protection, soundproofing, and fire resistance. Wall panels offer superior performance, can be easily cut and assembled, effectively address wall cracking issues, and integrate well with frame structures, steel structures, and irregularly shaped structures.
[0003] In existing technologies, the main transformer room of a substation is the core part of the substation, primarily responsible for converting high-voltage electricity into low-voltage electricity and housing transformer equipment. The equipment inside the main transformer room includes transformers, circuit breakers, and disconnect switches. To ensure the normal operation and safe use of the internal equipment, the main building requirements for the main transformer room are primarily focused on fire protection. Therefore, the wall panels of the main transformer room in existing technologies mainly have fire-resistant properties. Since the substation equipment generates significant noise during operation, the wall panels also need noise reduction capabilities to reduce noise pollution in the main transformer room. However, existing wall panels have relatively limited functionality, only possessing either fire protection or noise reduction capabilities. To achieve both fire protection and noise reduction in the main transformer room wall panels, existing wall panel manufacturers often assemble individual wall panels into a single unit. This results in a heavy overall structure, reduced rigidity, and a short service life for the existing multi-functional wall panels, leading to low practicality and poor economic efficiency.
[0004] In addition, the equipment in the main transformer room is mostly in automated mode. In order to ensure the normal operation of the power equipment, the electromagnetic interference protection performance of the main transformer room is extremely high. However, the existing wall panels do not have electromagnetic shielding function, and special electromagnetic shielding equipment needs to be set up, which leads to the high operating cost of the existing main transformer room. Therefore, a fireproof and noise-reducing wall panel for substations is needed to solve the problems of the single function of the existing wall panels, and the problems of poor wall panel rigidity, short service life and low function of multi-functional composite wall panels.
