TECHNICAL FIELD

[0001] The application belongs to the technical field of power distribution rooms, and particularly relates to a novel power distribution room of a transformer substation. BACKGROUND

[0002] The power distribution room of a transformer substation is an important place for distributing and controlling electric power in the transformer substation, and various electrical equipment such as transformers, switch cabinets, power distribution cabinets, capacitor banks and the like are installed inside, which functions to transmit high-voltage electric power inputted by the transformer substation to various electric equipment and lines after being reduced in voltage, distributed and controlled, so as to provide guarantee for the stable operation and reliable power supply of the power system, and meanwhile, auxiliary facilities such as ventilation, lighting, fire fighting and the like are provided to ensure a good equipment operation environment and personnel safety.

The power distribution room is installed outdoors, the blowing mechanism is fixedly installed on one side of the power distribution room, a strip-shaped air vent for hot air to flow out is formed on the other side of the power distribution room, the opening and closing mechanism is fixedly installed on the power distribution room, and the illumination mechanism is fixedly installed in the power distribution room. The intelligent power distribution room can suck air from the outside into the box through the heat dissipation fan, and the opening and closing mechanism works to make the hot air in the box quickly blow out through the strip-shaped air vent, so that the temperature in the box is quickly reduced, and the influence of high heat in the power distribution room on the circuit is avoided.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] refer to Figure 1 A novel substation distribution room includes a distribution room 1. A bottom support frame 14 is fixedly installed on the bottom surface of the distribution room 1, and multiple fixed lugs 15 are fixedly installed on the sides of the bottom support frame 14. The bottom support frame 14 facilitates the isolation of the distribution room 1 from the ground, which can prevent moisture and water accumulation and erosion, and extend the service life of the main structure of the distribution room. The multiple fixed lugs 15 can be used to firmly fix the entire distribution room to the foundation with bolts and other connectors, which can enhance the stability of the distribution room in the outdoor environment, resist the impact of strong winds and other severe weather, and ensure the safe operation of the internal electrical equipment.

[0021] refer to Figure 1A sealed door 16 is hinged to the front of the power distribution room 1, and a ventilation louver is fixedly installed on the front of the sealed door 16. The sealed door 16 can effectively block external dust and debris from entering the power distribution room 1, ensuring a clean operating environment for the internal electrical equipment. The ventilation louver, while ensuring a certain degree of airtightness, allows air circulation and can effectively dissipate the heat generated by the operation of the electrical equipment in the power distribution room, preventing the equipment performance and service life from being affected by excessive temperature, and maintaining a suitable temperature environment in the power distribution room.

[0022] refer to Figure 1 , Figure 2 and Figure 3 A rectangular gas supply pipe 2 is fixedly installed near the top inside the power distribution room 1. Multiple solenoid valves 12 are symmetrically fixedly installed on the outer surface of the rectangular gas supply pipe 2. The rectangular gas supply pipe 2 facilitates the subsequent delivery of fire extinguishing gas to the entire power distribution room 1. The multiple solenoid valves 12 are symmetrically distributed and can accurately control the gas delivery in different areas. In the event of a fire, the solenoid valves 12 in the corresponding areas can be selectively opened by the control element according to the fire source location fed back by the sensor, so that the subsequent fire extinguishing agent can be accurately delivered to the vicinity of the fire point, thereby improving the fire extinguishing efficiency.

[0023] refer to Figure 1 , Figure 2 A protective housing 3 is fixedly installed on the left side of the power distribution room 1. Heptafluoropropane extinguishing agent 4 is fixedly installed inside the protective housing 3. A sealing plate 13 is fixedly installed on the front side of the protective housing 3 by bolts. A transparent observation window is fixedly installed on the front side of the sealing plate 13. The protective housing 3 protects the heptafluoropropane extinguishing agent 4 from external physical damage and prevents leakage of the extinguishing agent due to collisions or other accidents. The sealing plate 13 is fixed by bolts and is easy to disassemble, which facilitates the inspection and maintenance of the heptafluoropropane extinguishing agent 4 inside. The transparent observation window allows the staff to directly observe the storage status of the heptafluoropropane extinguishing agent 4 without opening the sealing plate 13, so as to discover potential problems in time and take measures to ensure that the fire extinguishing system is always available.

[0024] refer to Figure 1 , Figure 2 and Figure 3The top end of the heptafluoropropane extinguishing agent 4 is fixedly provided with a connecting pipeline 5, and the outer surface of the connecting pipeline 5 is fixedly provided with a solenoid valve 6. One end of the connecting pipeline 5 extends into the inside of the power distribution room 1 and is fixed to the outer surface of the rectangular gas supply pipe 2. The connecting pipeline 5 can be used as a channel for conveying the heptafluoropropane extinguishing agent 4, and can connect the stored extinguishing agent with the rectangular gas supply pipe 2 in the power distribution room. The solenoid valve 6 can control the overall conveying of the extinguishing agent, and is kept closed under normal circumstances to prevent leakage of the extinguishing agent. When the solenoid valve 6 is opened, the extinguishing agent in the heptafluoropropane extinguishing agent 4 can enter the inside of the rectangular gas supply pipe 2 under the action of pressure through the connecting pipeline 5, which facilitates subsequent fire extinguishing operations.

[0025] With reference to Figure 1 , Figure 2 and Figure 3 , a plurality of monitoring sensors are fixedly arranged on the top surface of the power distribution room 1, and the monitoring ends of the plurality of monitoring sensors extend into the inside of the power distribution room 1. The solenoid valve 6 and the monitoring sensors are electrically connected to a control element arranged in the inside of the power distribution room 1. The plurality of monitoring sensors can monitor the inside environment of the power distribution room 1 in all directions and without dead angles. These sensors are composed of a smoke sensor, a temperature sensor and a flame sensor. The smoke sensor can sensitively capture smoke generated in the early stage of fire, the temperature sensor can quickly detect abnormal temperature changes, and the flame sensor can quickly respond to open flames. Once the early stage signals of fire such as smoke, temperature changes and flames are monitored, the signals will be transmitted to the control element. The control element mainly includes a programmable logic controller (PLC) and a microcontroller. The PLC can perform complex logic operations and sequence control, and the microcontroller can accurately process sensor data and execute control instructions. After receiving the signals, the control element can timely control the solenoid valve 6 to open according to the preset program, and then start the fire extinguishing process to gain valuable time for timely extinguishing the fire and minimize fire loss. The control element and the control circuit are existing mechanisms, and will not be described in detail here.

[0026] With reference to Figure 1 , Figure 2 and Figure 3 , a plurality of mounting plates 7 are arranged at equal intervals in the inside of the rectangular gas supply pipe 2, and the bottom surface of each of the plurality of mounting plates 7 is provided with a gas supply pipeline 8. The top surface of the mounting plate 7 is provided with an adjusting mechanism 9 connected with the gas supply pipeline 8. The mounting plate 7 is arranged to correspond to different equipment installation areas in the inside of the power distribution room 1, so that the gas supply pipelines 8 are uniformly distributed, and the heptafluoropropane extinguishing agent can be uniformly distributed to each gas supply pipeline 8 in the rectangular gas supply pipe 2. The adjusting mechanism 9 provides convenience for adjusting the position of the gas supply pipeline 8. By adjusting the height of the gas supply pipeline 8, the layout of different electrical equipment in the power distribution room 1 and the distribution of fire risk areas can be better adapted, so that the extinguishing agent can more accurately cover the areas where fire may occur, and the fire extinguishing effect is improved.

[0027] Reference Figure 2 , Figure 3 , the adjusting mechanism 9 includes an electric push rod 901, a connecting limiting rod 902, the top surface of the mounting plate 7 is fixedly installed with the electric push rod 901, the telescopic end of the electric push rod 901 penetrates the top surface of the mounting plate 7, the telescopic end of the electric push rod 901 is fixed with the outer surface of the gas supply pipeline 8, the top surface of the mounting plate 7 is movably provided with two connecting limiting rods 902, and the bottom ends of the two connecting limiting rods 902 are fixed with the outer surface of the gas supply pipeline 8; when the monitoring sensor finds that the equipment running temperature of a certain area in the power distribution room 1 abnormally rises, there is a higher fire risk, the electric push rod 901 can be controlled to start to make the telescopic end elongate or shorten, drive the gas supply pipeline 8 to approach the area, so that the fire extinguishing agent can be sprayed more quickly and more concentratedly to the area when the fire occurs, the connecting limiting rod 902 plays a limiting role in the movement of the gas supply pipeline 8 on the one hand, ensures the stable movement of the gas supply pipeline 8 under the push of the electric push rod 901, and enhances the stability of the connection between the gas supply pipeline 8 and the mounting plate 7 on the other hand, so that the gas supply pipeline 8 can reliably transport the fire extinguishing agent in the whole operation process of the fire extinguishing system.

[0028] Reference Figure 2 , Figure 3 , the gas supply pipeline 8 is fixedly installed with a plurality of spray heads 10 close to the bottom outer surface, and the left and right ends of the gas supply pipeline 8 are respectively fixedly installed with soft connecting pipes 11, and the ends, away from the gas supply pipeline 8, of the soft connecting pipes 11 are fixed with the outer surface of the rectangular gas supply pipe 2; the plurality of spray heads 10 can uniformly spray the heptafluoropropane extinguishing agent in the form of spray to the internal space of the power distribution room 1, increase the contact area of the extinguishing agent and the fire source, improve the extinguishing efficiency, the soft connecting pipe 11 is a metal hose with good flexibility, which can not only adapt to the position change of the gas supply pipeline 8 under the action of the adjusting mechanism 9, but also can ensure good connection sealing under the condition of pressure change in the rectangular gas supply pipe 2, so that the heptafluoropropane extinguishing agent can be smoothly transported from the rectangular gas supply pipe 2 to the gas supply pipeline 8 and effectively sprayed through the spray head 10, thereby providing reliable fire extinguishing protection for the power distribution room 1.

[0029] The implementation principle of the new power substation distribution room embodiment of the application is as follows: when the monitoring sensor (including a smoke sensor, a temperature sensor, and a flame sensor) in the distribution room 1 detects abnormal signals such as smoke, temperature change, and flame in the initial stage of fire, the signals are transmitted to a control element (such as a programmable logic controller PLC and a microcontroller), and the control element opens electromagnetic valve one 6 according to a preset program, and heptafluoropropane extinguishing agent 4 flows into the rectangular gas supply pipe 2 from the protective shell 3 through the connecting pipeline 5, and a plurality of electromagnetic valve two 12 symmetrically distributed on the rectangular gas supply pipe 2 can be selectively opened by the control element according to the fire source position fed back by the monitoring sensor, and at the same time, the electric push rod 901 in the adjusting mechanism 9 drives the gas supply pipeline 8 and the spray head 10 to move downward, so that the heptafluoropropane extinguishing agent 4 is accurately sprayed in the form of mist through the spray head 10 into the distribution room, which greatly increases the contact area with the fire source, and the flexible connecting pipe 11 adapts to the position change of the gas supply pipeline 8 and the pressure change in the rectangular gas supply pipe 2, so as to ensure the smooth delivery and spraying of the extinguishing agent, and realize rapid extinguishing.

[0030] After the extinguishing is completed, the fan at the front side of the distribution room 1 is started to work cooperatively with the ventilation louvers to promote the rapid discharge of the extinguishing agent in the distribution room 1, thereby reducing the influence on personnel. In the normal operation state of the distribution room 1, the fan and the ventilation louvers cooperate to dissipate heat, and when the monitoring sensor detects a fire, the fan stops running, the extinguishing agent in the heptafluoropropane extinguishing agent 4 enters the rectangular gas supply pipe 2 and is sprayed out through the spray head 10, effectively extinguishing the fire in the distribution room 1, and significantly improving the safety.

[0031] The above embodiments are only used to illustrate the technical solutions of the application, but not to limit them; although the application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the application.
