[0002] A substation is a place in the power system that transforms voltage and current, receives electric energy and distributes electric energy. The substation in a power plant is a step-up substation, and its function is to step up the electric energy generated by the generator and feed it into the high-voltage power grid. There are many types of substations, such as box-type substations. Box-type substations, also called prefabricated substations or prefabricated substations, are a kind of high-voltage switchgear, distribution transformers and low-voltage distribution devices, which are factory-prefabricated indoor and outdoor compact distribution equipment arranged in one according to a certain wiring scheme, that is, the functions of transformer step-down and low-voltage distribution are organically combined.

[0003] The patent document with the prior art announcement number CN218525962U provides a box-type substation. The device is provided with a drainage mechanism. When the substation body is working in a rainwater environment, when the rainwater falls above the water storage tank, the rainwater will enter the inner side of the water storage tank through the water inlet of the baffle above the water storage tank for collection. When the rainwater enters the inner side of the water inlet, the filter net inside the water inlet will filter the impurities in the rainwater. When the rainwater inside the water storage tank accumulates a certain capacity, it will be discharged through the drain pipe. At the same time, the water pump is started to pump the rainwater inside the water storage tank through the water inlet pipe to be discharged through the outlet pipe, thereby effectively preventing rainwater from seeping into the inner side of the substation body, and providing effective protection for the waterproofing inside the substation body. Although the current substation provides effective protection for the waterproofing inside the substation, it does not have the function of automatic fire extinguishing. As a result, due to the large number of electrical components inside the substation, the heat generated during operation can easily cause the internal electrical components to spontaneously combust, which needs to be manually extinguished.

The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0019] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The utility model embodiment provides a box-type substation with fire alarm function, such as Figure 1-4 As shown, it includes: a mounting base 1, the top of which is fixedly connected to a transformer box body 2; the interior of the transformer box body 2 is divided into two transformer chambers 4 and a fire chamber 5 by two partitions 3, and the interior of the fire chamber 5 is provided with two carbon dioxide pressure tanks 6, and the two carbon dioxide pressure tanks 6 are connected by an I-type pipe 7, and the top ends of the I-type pipe 7 respectively penetrate the partition 3 and extend to the nozzle 8, and the nozzle 8 is connected to the I-type pipe 7, and the nozzle 8 is fixedly connected to the transformer box body 2; automatic fire extinguishing detection mechanisms 9 are provided on both sides of the nozzle 8; heat dissipation mechanisms 10 are provided on both sides of the transformer box body 2 to prevent the internal electrical components from catching fire due to excessive temperature.

[0021] It should be noted that when the detection mechanism 9 detects that the electrical components inside the transformer cavity 4 are spontaneously combusting, the carbon dioxide inside the carbon dioxide pressure tank 6 is automatically transported to the nozzle 8 through the industrial pipe 7, and finally sprayed by the nozzle 8 into the transformer cavity 4 for fire extinguishing. When the electrical components inside the transformer box body 2 are spontaneously combusting, the fire is automatically extinguished, which solves the problem that although the current substation provides effective protection for the waterproofing inside the substation, it does not have the function of automatic fire extinguishing, resulting in a large number of electrical components inside the substation and the heat generated during operation easily causing the internal electrical components to spontaneously combust, which requires manual extinguishing.

[0022] In a further preferred embodiment of the present invention, Figure 1 As shown, the detection mechanism 9 includes: a temperature sensor 11 is provided on one side of the nozzle 8, a smoke sensor 12 is provided on the side of the nozzle 8 away from the temperature sensor 11, and the temperature sensor 11 and the smoke sensor 12 are fixedly connected to the transformer box body 2; a controller 13 is fixedly connected to the top of the fire-fighting cavity 5, and a solenoid valve 14 is fixedly connected to the industrial pipe 7 near the nozzle 8, and the temperature sensor 11, the smoke sensor 12 and the solenoid valve 14 are all electrically connected to the controller 13.

[0023] In this embodiment, the temperature sensor 11 and the smoke sensor 12 simultaneously monitor the temperature and the amount of smoke inside the transformer chamber 2, and transmit the monitoring data to the inside of the controller 13. When the temperature and the amount of smoke inside the transformer chamber 4 reach the maximum threshold value set inside the controller 13, the controller 13 determines that there is a fire. At the same time, the controller 13 opens the solenoid valve 14 on the transformer chamber 4 on the fire side, and the carbon dioxide inside the carbon dioxide pressure tank 6 can be transported due to the pressure.

[0024] In a further preferred embodiment of the present invention, Figure 2 As shown, the heat dissipation mechanism 10 includes: heat dissipation ports 15 are provided on both sides of the bottom of the transformer box body 2, a mounting bracket 16 is provided on one side of the heat dissipation port 15, the mounting bracket 16 is fixedly connected to the transformer box body 2, and a dustproof net 17 is provided inside the heat dissipation port 15, and the dustproof net 17 is fixedly connected to the transformer box body 2; a micro motor 18 is fixedly connected inside the mounting bracket 16, and a heat dissipation blade 19 is fixedly connected to the output end of the micro motor 18.

[0025] In this embodiment, the micro motor 18 is started, and the output end of the micro motor 18 drives the heat dissipation blades 19 to rotate. The heat dissipation blades 19 rotate and blow the heat inside the transformer cavity 4 out from the heat dissipation port 15, thereby dissipating the heat of the electrical components inside the transformer cavity 4 and reducing the probability of spontaneous combustion of the electrical components due to high temperature.

[0026] In a further preferred embodiment of the present invention, Figure 1 As shown, ventilation openings 20 are provided near the heat dissipation openings 15 of the transformer box body 2, and the ventilation openings 20 are all inclined.

[0027] In this embodiment, the outside air can enter the interior of the transformer chamber 4 through the ventilation port 20, and then cooperate with the heat dissipation port 15 to achieve the purpose of circulating the air inside the transformer chamber 4. The inclined setting of the ventilation port 20 can effectively prevent rainwater from entering the interior of the transformer chamber 4.

[0028] In a further preferred embodiment of the present invention, Figure 1 As shown, the partitions 3 are fixedly connected with alarms 21 near the heat dissipation openings 15 , and the alarms 21 are electrically connected to the controller 13 .

[0029] In this embodiment, the controller 13 can control the alarm 21 to start when it determines that a fire has occurred, thereby achieving the purpose of reminding.

[0030] In a further preferred embodiment of the present invention, Figure 3 As shown, one side of the transformer chamber 4 and the fire fighting chamber 5 is provided with a box door 22 with tempered glass, and the box door 22 is hingedly connected to the transformer box body 2 and the partition 3 respectively.
