Description
Technical Field
[0001] The utility model belongs to the technical field of transformer substations, and in particular relates to a high-safety energy-saving box-type transformer substation for residential areas. Background Art
[0002] High-security and energy-saving box-type substation is a power facility designed for residential areas to provide safe, reliable and energy-saving power supply. This substation combines advanced technology and environmental protection concepts to ensure that the power demand in residential areas is met while reducing the impact on the environment. High-security and energy-saving box-type substation adopts a fully enclosed design with dust-proof, rodent-proof, fire-proof, heat-proof and other characteristics, and can operate stably under severe weather conditions. At the same time, the equipment in the substation has undergone strict quality control and safety testing to ensure that no safety accidents will occur during operation.
[0003] At present, most box-type substations adopt a fully enclosed design. Although this design helps to improve the safety and operating efficiency of the equipment, it also brings certain safety hazards. Once an internal fire occurs, due to the closed nature of the box, the fire and smoke are difficult to be discovered by the outside world in time, thus delaying the best time to extinguish the fire. In addition, ordinary personnel lack the ability to open the box-type substation, resulting in the inability to quickly and effectively control the fire. In this case, the fire may spread rapidly, posing a serious threat to the surrounding environment and the safety of life and property of residents. The flames may destroy key equipment in the substation, causing power supply interruptions and inconvenience to residents' lives. At the same time, smoke and toxic gases may spread to surrounding areas, affecting the health of residents. What's more serious is that if the fire cannot be effectively controlled, it may cause secondary disasters such as explosions, causing greater harm to surrounding residents.
[0004] Therefore, it is very necessary to invent a high-safety energy-saving box-type substation for residential areas. Utility Model Content

[0020] As attached Figure 1 To Attachment Figure 3 As shown:
[0021] The utility model provides a high-safety energy-saving box-type substation for residential areas, comprising a substation box casing 1, a heat dissipation and fire extinguishing system 2, a warning sign 3, a rain shelter 4 and a photovoltaic module 5. The heat dissipation and fire extinguishing system 2 is fixedly installed above the substation box casing 1, the warning sign 3 is located below the heat dissipation and fire extinguishing system 2, the warning sign 3 is fixedly installed on the substation box casing 1, a rain shelter 4 is fixedly installed above the substation box casing 1, and is located above the heat dissipation and fire extinguishing system 2, the photovoltaic module 5 is fixedly installed on the rain shelter 4, and the heat dissipation and fire extinguishing system 2 cleverly combines the heat dissipation and fire extinguishing functions, and effectively prevents the risk of fire caused by overheating of the equipment.
[0022] The heat dissipation fire extinguishing system 2 includes a heat dissipation fire extinguishing main pipe 21, a fire extinguisher 22, a fire extinguisher box 23, a heat dissipation fan 24, a heat dissipation fire extinguishing auxiliary pipe 25, a retaining frame 26, a temperature sensor 27, a through hole 28 and a crushing ring 29. The heat dissipation fire extinguishing main pipe 21 is fixedly installed on the substation box casing 1, one end of the heat dissipation fire extinguishing main pipe 21 is connected to the fire extinguisher 22, the fire extinguisher 22 is arranged in the fire extinguisher box 23, and the fire extinguisher box 23 is fixedly installed on the substation box casing 1; the heat dissipation fan 24 is fixedly installed on the other end of the heat dissipation fire extinguishing main pipe 21, and the two The heat dissipation and fire extinguishing auxiliary pipe 25 is fixedly mounted on the heat dissipation and fire extinguishing main pipe 21 in a mirror image and is interconnected. At least two retaining frames 26 are fixedly mounted on the heat dissipation and fire extinguishing main pipe 21 and the heat dissipation and fire extinguishing auxiliary pipe 25, and a temperature sensor 27 is fixedly mounted below the retaining frame 26. The heat dissipation and fire extinguishing main pipe 21 and the heat dissipation and fire extinguishing auxiliary pipe 25 are provided with a plurality of through holes 28, and a breaking ring 29 is arranged around the through hole 28. The breaking ring 29 is fixedly mounted on the heat dissipation and fire extinguishing main pipe 21 or the heat dissipation and fire extinguishing auxiliary pipe 25. The heat dissipation and fire extinguishing system 2 has two working modes: heat dissipation and fire extinguishing. The dual functions of heat dissipation and fire extinguishing are realized. At the same time, the setting of the heat dissipation and fire extinguishing auxiliary pipe 25 enhances the heat dissipation effect of the system, so that the heat inside the equipment can be quickly dissipated.
[0023] Embodiment 1:
[0024] Specifically, solenoid valves are fixedly installed at both ends of the heat dissipation and fire extinguishing main pipe 21. The solenoid valve close to the heat dissipation fan 24 is a heat dissipation solenoid valve, and the solenoid valve close to the fire extinguisher 22 is a fire extinguishing solenoid valve. The working mode of the heat dissipation and fire extinguishing system 2 is switched by controlling the opening and closing of the solenoid valve. In addition, a switch for controlling the heat dissipation and fire extinguishing solenoid valves is installed on the outside of the substation box casing 1, and the working mode of the heat dissipation and fire extinguishing system 2 can be switched manually.
[0025] Specifically, the fire extinguisher 22, the fire extinguisher box 23 and the heat dissipation fan 24 are arranged outside the heat dissipation fire extinguishing main pipe 21. The fire extinguisher 22 is a gas fire extinguisher, and the fire extinguishing medium stored inside is carbon dioxide gas. The fire extinguishing medium stored inside the fire extinguisher 22 is in a high pressure state.
[0026] Specifically, the heat dissipation fire extinguishing main pipe 21 and the heat dissipation fire extinguishing auxiliary pipe 25 are arranged above the substation equipment inside the substation box casing 1, and the temperature sensor 27 installed on the retaining frame 26 is arranged between the heat dissipation fire extinguishing main pipe 21 and the heat dissipation fire extinguishing auxiliary pipe 25. This design can effectively take away the heat generated by the substation equipment, and facilitate the coverage effect of carbon dioxide to be more excellent, thereby improving the fire extinguishing treatment effect.
[0027] Specifically, the breaking ring 29 is a glass thermal sensing element, and the breaking ring 29 is a circular ring structure. As the temperature rises, the breaking ring 29 will break, thereby expanding the diameter of the through hole 28 and improving the coverage and efficiency of carbon dioxide.
[0028] Specifically, the temperature sensor 27 and the solenoid valve switch are connected to the input end of the controller, and the output end of the controller is connected to the heat dissipation and fire extinguishing solenoid valve. After the temperature inside the substation box casing 1 reaches the set value, the temperature sensor 27 opens or closes the heat dissipation and fire extinguishing solenoid valve through the controller, thereby switching the working mode of the heat dissipation and fire extinguishing system 2. One of the heat dissipation and fire extinguishing solenoid valves is always in a closed state or an open state.
[0029] Embodiment 2:
[0030] Under normal operating conditions, the heat dissipation fan 24 of the heat dissipation fire extinguishing system 2 operates normally, the heat dissipation solenoid valve of the heat dissipation fire extinguishing main pipe 21 is in an open state, and the fire extinguishing solenoid valve is in a closed state. The suction generated by the heat dissipation fan 24 discharges the heat generated by the substation equipment inside the substation box casing 1, thereby reducing the internal temperature. When a fire occurs in the substation equipment inside the substation box casing 1, after the temperature reaches a certain level, the temperature sensor 27 of the heat dissipation fire extinguishing system 2 opens the fire extinguishing solenoid valve and closes the heat dissipation solenoid valve through the controller, and the carbon dioxide inside the fire extinguisher 22 enters the heat dissipation fire extinguishing main pipe 21 and the heat dissipation fire extinguishing auxiliary pipe 25, thereby suppressing the fire below and extinguishing the fire. If the fire is large and the temperature gradually rises, the crushing rings 29 on the heat dissipation fire extinguishing main pipe 21 and the heat dissipation fire extinguishing auxiliary pipe 25 are broken, thereby expanding the diameter of the through hole 28 and improving the coverage range and efficiency of the carbon dioxide.
[0031] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
