[0045] The embodiment of the present invention solves the technical problem in the prior art that the type of fire extinguishing device adapted to the target electrical cabinet is difficult to determine by providing a method for testing and evaluating the fire extinguishing performance of a built-in fire extinguishing device in an electrical cabinet.

[0046] The technical solution of the present invention is to solve the above technical problems, and the overall idea is as follows:

[0047] A method for testing and evaluating the fire extinguishing performance of a built-in fire extinguishing device in an electrical cabinet, the method comprising: installing any type of fire extinguishing device in a target electrical cabinet, wherein the types of fire extinguishing devices include: aerosol fire extinguishing device, carbon dioxide fire extinguishing device, clean gas fire extinguishing device, dry powder fire extinguishing device and water mist spray device; setting a number of fire points in the target electrical cabinet and igniting them; based on the type of fire extinguishing device, extinguishing the target electrical cabinet, and obtaining a fire extinguishing data set corresponding to the type of fire extinguishing device, wherein the fire extinguishing data set includes: fire extinguishing spray volume, fire extinguishing time, cooling rate, burn rate, anti-reignition rate and the operating status of the target electrical cabinet; based on the fire extinguishing data set corresponding to the type of fire extinguishing device, evaluating the performance of the type of fire extinguishing device; and determining the best type of fire extinguishing device for the target electrical cabinet based on the results of the performance evaluations.

[0048] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0049] First of all, the term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0050] The present invention provides Figure 1 A method for testing and evaluating the fire extinguishing performance of a built-in fire extinguishing device in an electrical cabinet is shown, comprising steps S11-S15:

[0051] Step S11, any type of fire extinguishing device is built into the target electrical cabinet, wherein the types of fire extinguishing devices include: aerosol fire extinguishing device, carbon dioxide fire extinguishing device, clean gas fire extinguishing device, dry powder fire extinguishing device and water mist spray device.

[0052] Electrical cabinets are enclosed metal boxes used to house and protect electrical equipment, components, and related wiring. Electrical cabinets are widely used in industrial, commercial, and residential environments to ensure the safe operation and maintenance of electrical systems.

[0053] It is understandable that there are many types of electrical cabinets, including: distribution cabinets, control cabinets, instrument cabinets, communication cabinets, network cabinets and power cabinets. Different types of electrical cabinets have different structures and are suitable for different fire extinguishing devices. The purpose of the present invention is to determine the fire extinguishing device suitable for the target type of electrical cabinet.

[0054] Aerosol fire extinguishing device: A device that suppresses flames by releasing tiny particles of matter (aerosol). The particles can spread quickly and cover the burning area, thus interrupting the combustion chain reaction.

[0055] Carbon dioxide fire extinguishing device: The device reduces the oxygen concentration in the burning area by spraying high-pressure carbon dioxide gas, thereby suffocating the flame.

[0056] Clean gas fire extinguishing device: uses clean gases such as heptafluoropropane (HFC-227ea) and IG541 to extinguish fire by reducing oxygen concentration or chemical inhibition.

[0057] Dry powder fire extinguishing device: uses dry powder to cover the surface of the burning object, isolate the air and interrupt the combustion process.

[0058] Water mist spray device: Atomizes water into fine droplets through high pressure to quickly cool the combustion products and dilute the oxygen concentration in the surrounding air.

[0059] Any type of fire extinguishing device can be built into the target electrical cabinet.

[0060] Step S12, setting a number of ignition points in the target electrical cabinet and igniting.

[0061] An ignition point is set in the target electrical cabinet, and the number of ignition points is at least one. In order to simulate the real fire scene as much as possible, an ignition point can be set at the line interface of the target electrical cabinet.

[0062] Step S13, based on this type of fire extinguishing device, extinguish the target electrical cabinet and obtain a fire extinguishing data set corresponding to this type of fire extinguishing device, wherein the fire extinguishing data set includes: fire extinguishing spray volume, fire extinguishing duration, cooling rate, burn rate, anti-reignition rate and the operating status of the target electrical cabinet.

[0063] The fire extinguishing device of the type selected in step S11 extinguishes the fire in the target electrical cabinet, and simultaneously collects data related to the fire extinguishing effect for evaluating the performance and effect of the fire extinguishing device.

[0064] Fire extinguishing spray volume: refers to the mass of fire extinguishing agent (such as gas, foam or dry powder) released by the fire extinguishing device during the fire extinguishing process.

[0065] Fire extinguishing time: refers to the length of time required from the activation of the fire extinguishing device to the complete extinguishing of the fire. This reflects the response speed and efficiency of the fire extinguishing device.

[0066] Cooling rate: Indicates the speed at which the temperature inside the electrical cabinet drops after the fire is extinguished. Rapid cooling helps prevent further damage to the equipment due to high temperature and reduces the possibility of re-ignition.

[0067] Burn rate: It is used to measure the extent of damage to the electrical cabinet and its internal components in a fire, and can be calculated based on the value of the lost property.

[0068] Anti-reignition rate: refers to the ability of a fire extinguishing device to prevent a fire from burning again after it has been initially extinguished. A high anti-reignition rate means that the fire extinguishing device can effectively prevent the fire from recurring.

[0069] The operating status of the target electrical cabinet: refers to whether the electrical cabinet can resume normal operation after fire extinguishing.

[0070] Step S14: Based on the fire extinguishing data set corresponding to the fire extinguishing device of this type, a performance evaluation is performed on the fire extinguishing device of this type.

[0071] Specifically include:

[0072]

[0073] Among them, P n is the score corresponding to the performance evaluation of the nth type of fire extinguishing device, M n is the fire extinguishing spray volume corresponding to the nth type of fire extinguishing device, L n is the cooling rate corresponding to the nth type of fire extinguishing device, T n is the fire extinguishing time corresponding to the nth type of fire extinguishing device, S n is the burning rate corresponding to the nth type of fire extinguishing device, F n is the anti-reignition rate corresponding to the nth type of fire extinguishing device, Y n is the operating status of the target electrical cabinet after the fire is extinguished by the nth type of fire extinguishing device. If the target electrical cabinet is operating normally, Y n If the target electrical cabinet cannot operate normally, Y n is 0, β is greater than 0, wherein the anti-reignition rate is only 0 or 1.

[0074] Generally speaking, the shorter the fire extinguishing time, the better. The fire extinguishing time appears as a direct term in the numerator, which means that a shorter fire extinguishing time will result in a lower score (because the goal is to minimize the fire extinguishing time). The cooling rate can be indexed, and the importance of rapid cooling can be emphasized. The present invention also combines the anti-reignition rate and the operating status of the electrical cabinet. It shows that whether the equipment can resume normal working state has an impact on the anti-reignition rate.

[0075] The denominator uses a logarithmic function to process the fire extinguishing spray volume and burn rate, which helps to compress the large range of values ​​and make the weight in the calculation more reasonable. In addition, it also means that both the amount of extinguishing agent used and the burn situation are taken into account at the same time, so that a higher fire extinguishing spray volume or burn rate will result in a lower overall score.

[0076] Determine the burn-out rate, including:

[0077]

[0078] Among them, Z n is the total value of all equipment in the target electrical cabinet, D n It is the total value of the equipment to be replaced in the target electrical cabinet.

[0079] Step S15, determining the best type of fire extinguishing device for the target electrical cabinet based on the results of several performance evaluations.

[0080] Specifically, the method includes: traversing the scores corresponding to the performance evaluations of all types of fire extinguishing devices, and taking the type of fire extinguishing device with the highest score as the optimal type of fire extinguishing device for the target electrical cabinet.

[0081] In other words, for the target electrical cabinet, the type of fire extinguishing device with the highest score is the most suitable for the target electrical cabinet and has the best fire extinguishing efficiency.

[0082] Steps S11 to S15 may be performed for different types of electrical cabinets to determine the most suitable type of fire extinguishing device for the different types of electrical cabinets.

[0083] In addition, after obtaining the optimal type of fire extinguishing device for the target electrical cabinet, the method also includes: determining a combination of several ignition points set in the target electrical cabinet; under each combination, re-igniting the new target electrical cabinet, and extinguishing the new target electrical cabinet based on the optimal type of fire extinguishing device; obtaining a fire extinguishing data set under each combination; determining a corresponding performance evaluation score under each combination based on the fire extinguishing data set under each combination; and determining the optimal fire extinguishing application scenario for the optimal type of fire extinguishing device based on the corresponding performance evaluation scores under several combinations.

[0084] Several combinations of ignition points are used to simulate various fire scenarios that may occur in the target electrical cabinet. For each preset combination of ignition points, a new target electrical cabinet that has not experienced a fire is used for actual ignition testing. In each fire extinguishing experiment, a fire extinguishing data set is obtained, including the fire extinguishing spray volume, fire extinguishing time, cooling rate, burn loss rate, anti-reignition rate, and the operating status of the electrical cabinet.

[0085] Based on the fire extinguishing data set, each combination of fire points is quantitatively scored. By comparing and analyzing the performance evaluation scores of all combinations of fire points, it is possible to identify the optimal type of fire extinguishing device with the highest fire extinguishing efficiency when extinguishing the target electrical cabinet in which fire scenarios.

[0086] Determining the best fire extinguishing application scenario for the best type of fire extinguishing device includes: taking the combination of fire points corresponding to the highest value of the corresponding performance evaluation scores under several combination methods as the best fire extinguishing application scenario for the best type of fire extinguishing device.

[0087] In summary, the present invention provides a method for testing and evaluating the fire extinguishing performance of a built-in fire extinguishing device in an electrical cabinet, the method comprising: installing any type of fire extinguishing device in a target electrical cabinet, wherein the types of fire extinguishing devices include: aerosol fire extinguishing device, carbon dioxide fire extinguishing device, clean gas fire extinguishing device, dry powder fire extinguishing device and water mist spray device; setting a number of fire points in the target electrical cabinet and igniting them; based on the type of fire extinguishing device, extinguishing the target electrical cabinet, and obtaining a fire extinguishing data set corresponding to the type of fire extinguishing device, wherein the fire extinguishing data set includes: fire extinguishing spray volume, fire extinguishing duration, cooling rate, burn rate, anti-reignition rate and the operating status of the target electrical cabinet; based on the fire extinguishing data set corresponding to the type of fire extinguishing device, evaluating the performance of the type of fire extinguishing device; and determining the best type of fire extinguishing device of the target electrical cabinet based on the results of several performance evaluations. The present invention can find out the best type of fire extinguishing device of the target electrical cabinet through performance evaluation, thereby improving the safety of the electrical cabinet.

[0088] In the relevant formulas for performance evaluation, the fire extinguishing time appears in the numerator as a direct term, which means that a shorter fire extinguishing time will result in a lower score (because the goal is to minimize the fire extinguishing time). The cooling rate can be indexed and indexed to emphasize the importance of rapid cooling. The present invention also combines the anti-reignition rate and the operating status of the electrical cabinet. It shows that whether the equipment can recover to normal working state has an impact on the anti-reignition rate.

In addition, it also means that the amount of fire extinguishing agent and the burn situation are taken into account at the same time, so that a higher fire extinguishing spray volume or burn rate will result in a lower overall score.
