[0003] However, the aforementioned patent has several limitations. In the event of an abnormal situation, the airbag is only attached to the inner wall of the clamping plate to protect the capacitor. Besides the capacitor, there are many other critical electrical components such as intelligent controllers, ammeters, and contactors. In the event of a fire or explosion, sparks and high temperatures generated by these components could trigger a larger accident, and the airbag cannot protect them. Furthermore, as a protective device, the airbag itself may develop quality problems due to long-term use. The alarm and detection effects inside the cabinet are limited. In reality, without timely automatic or manual intervention measures, such as fire extinguishing devices, the accident may continue to escalate. Utility Model Content

[0021] The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Reference Figure 1 , Figure 2 This utility model discloses a fireproof and explosion-proof capacitor compensation cabinet, including a cabinet body 1 and a mounting plate 3. The cabinet body 1 has an internal mounting frame 6. The mounting plate 3 and the mounting frame 6 are connected by bolts or slide rails, thereby separating a fireproof compartment 4 and an electrical compartment 5. The connection method between the mounting plate 3 and the mounting frame 6 makes installation and disassembly simple and quick.

[0023] Reference Figures 1 to 4 The electrical compartment 5 is equipped with high-voltage capacitors 15 and other related electrical components. Several explosion-proof panels 7 are arranged at intervals according to the positions of the high-voltage capacitors 15 within the electrical compartment 5. The explosion-proof panels 7 are bolted to the mounting frame 6. The explosion-proof panels 7 are composed of an outer steel layer 70 and an inner buffer layer 72. The outer steel layer 7 is corrugated and made of cold-rolled steel plate, which has high strength, impact resistance, and prevents fragmentation. The inner buffer layer contains rock wool and polyurethane foam, increasing the elasticity of the explosion-proof panel while reducing impact force. It also has excellent fire resistance, preventing flame penetration in abnormal situations.

[0024] The outer steel layer 70 of the explosion-proof plate 7 is coated with fire-retardant paint 71, specifically nano-ceramic fire-retardant paint, which has excellent fire-retardant performance and can effectively block the transfer of heat. With the nano-ceramic fire-retardant paint on the surface of the outer steel layer 70, even if the components inside the cabinet explode and burn, the heating rate of the outer steel layer 70 will be greatly reduced, further improving safety.

[0025] The fireproof compartment 4 is equipped with a detector 8, an alarm 9, a cooling fan 10, and a dry powder fire extinguishing device 11, which enters the electrical compartment 5 through the mounting plate 3; the side of the cabinet 1 is provided with heat dissipation holes 14, and the bottom of the cabinet is provided with pulleys 2. The dry powder fire extinguishing device 11 includes a fire extinguishing agent storage tank 111 and a fire extinguishing agent nozzle 110, and the fire extinguishing agent storage tank is located inside the fireproof compartment 4.

[0026] During normal operation, the cooling fan 10 runs continuously, effectively expelling heat from the electrical compartment 5 through the heat dissipation holes 14. The detector 8 monitors safety parameters such as temperature and smoke levels inside the electrical compartment 5 in real time, ensuring timely detection of potential safety hazards. This allows the cabinet 1 to both detect the internal conditions and alarm for abnormal situations.

[0027] In the event of an abnormal situation, if detector 8 detects an abnormal increase in temperature or excessive smoke concentration inside electrical compartment 5, it immediately triggers alarm 9 to issue an alarm signal, notifying operators to take appropriate measures. If a high-voltage capacitor 15 in electrical compartment 5 malfunctions, causing an explosion or fire, the explosion-proof plate 7 comes into play. Its outer steel layer 70, made of high-strength cold-rolled steel plate, withstands the impact of the explosion and prevents debris from flying; the surface nano-ceramic fireproof coating 71 slows down the external temperature rise of cabinet 1. The rock wool and polyurethane foam in the inner buffer layer 72 absorb the impact energy, protecting the structure of cabinet 1. Subsequently, the extinguishing agent nozzle 110 of the dry powder fire extinguishing device 11, driven by the control system, sprays dry powder extinguishing agent into electrical compartment 5 through the channel of mounting plate 3 to extinguish the flames and ensure safety.

[0028] The cabinet 1 has an opening at the bottom, and a removable dustproof base plate 12 is provided at the bottom opening. Since dust and other impurities accumulate at the bottom of the cabinet during use, or damaged parts fall to the bottom in case of an emergency, the removable dustproof base plate 12 allows for thorough cleaning of the bottom area of ​​the cabinet, effectively maintaining the cleanliness of the cabinet interior. Casters 2 located around the bottom of the cabinet allow the entire device to be easily moved to a designated location, facilitating relocation in case of an emergency or routine maintenance.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
