Description

Technical Field

[0002] With the advancement of dual-carbon goals, the demand for carbon footprint accounting for power equipment is increasing. As a key power component, composite insulators require careful accounting of their carbon emissions throughout their entire life cycle, which is of great guiding significance for enterprises to optimize production processes and achieve carbon reduction.

[0003] However, current industry methods for calculating the carbon footprint of composite insulators mostly follow a general path of "raw materials—production—transportation—use—disposal," using general carbon emission factors for rough calculations. However, the production process of composite insulators involves multiple steps, including raw material transportation, fitting manufacturing, core rod manufacturing, rubber compounding, and injection molding. The material consumption, energy use, and waste disposal methods differ significantly across these steps, resulting in varying carbon emission factors. Existing technologies fail to fully consider the actual production characteristics of different steps, breaking down the composite insulator production process into multiple steps and establishing suitable calculation models for each step. This leads to insufficient accuracy in the calculation results, failing to accurately reflect the carbon emissions of different steps in actual production.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0018] The module divisions described in this application are logical; in practical applications, different division methods may be used. For example, multiple modules may be combined or integrated into another system, or some features may be ignored or not executed. Furthermore, the connections, couplings, or communications in this application can be direct connections, couplings, or communications between related objects, or indirect connections, couplings, or communications through other devices. Moreover, the connections, couplings, or communications between objects can be electrical or other similar forms, and are not limited in this application. Independently described modules or sub-modules may or may not be physically separated: they may be implemented in software or hardware, and some modules or sub-modules may be implemented in software, with the processor calling the software to implement the functions of these modules or sub-modules, while other modules or sub-modules are implemented in hardware, such as through hardware circuits. Furthermore, some or all of the modules can be selected to achieve the purpose of this application's solution according to actual needs.

[0019] like Figure 1 , Figure 2 As shown, this invention provides a method for calculating the carbon footprint of composite insulators based on modular process steps, including: S101: Obtain the production process information of composite insulators, and based on the production process information, divide the production process of composite insulators into multiple process modules; In this embodiment, the production process information of composite insulators refers to the complete production process information of composite insulators from raw material entry to finished product exit. The production process includes, but is not limited to, raw material transportation, hardware manufacturing, core rod manufacturing, rubber compounding manufacturing, injection molding, and other links. The production process information refers to the sequence of each link, operation content, and process parameters. This production process information can be directly obtained through the enterprise's production management system.

[0020] For example, in this embodiment, the obtained composite insulator production process information shows that the production flow is as follows: raw material transportation, hardware preparation, mandrel preparation, compounding production, and injection molding, ultimately yielding the finished product. Based on this production process information, the production process can be divided into five independent process modules: raw material transportation module, hardware preparation module, mandrel preparation module, compounding production module, and injection molding module. Subsequent carbon footprint accounting will be carried out using these five process modules as the basic unit.

[0021] S102: Obtain the basic carbon emission data corresponding to each process module, and calculate the carbon emission of each process module based on the carbon emission calculation model preset for each process module. In this embodiment, basic carbon emission data refers to all carbon emission-related data generated by each process module during the production process, including but not limited to fuel consumption during raw material procurement and transportation, electricity consumption during production equipment operation, equipment wear and tear, and carbon emission data during waste disposal. This data can be collected through energy consumption metering equipment, production reports, material ledgers, or third-party testing reports. The carbon emission calculation model is a dedicated calculation model preset for the carbon emission characteristics of each process module. For example, the raw material transportation module uses a product model of fuel consumption and carbon emission factor, while the compound rubber manufacturing module uses a comprehensive calculation model of raw material usage, equipment energy consumption, and corresponding carbon emission factor. In this embodiment, the specific form of the model is not limited, as long as it can accurately reflect the carbon emission of the process module.

[0022] For example, in this embodiment, the basic data collected for the raw material transportation module includes: a transportation distance of 500 kilometers, a truck fuel consumption of 20L / 100km, and a diesel carbon emission factor of 2.63kgCO2 / L. Based on the accounting model corresponding to this process, the carbon emissions of the raw material transportation module can be calculated as: transportation distance × fuel consumption × carbon emission factor = 500km × 20L / 100km × 2.63kgCO2 / L = 263kgCO2. Similarly, for the hardware manufacturing module, by collecting data on steel usage and processing equipment power consumption, combined with the corresponding carbon emission factor, the carbon emissions of this module can be calculated. For the mandrel manufacturing, compound rubber manufacturing, and injection molding modules, corresponding preset accounting models can be used to calculate the carbon emissions of each process module.

[0023] S103: Summarize the carbon emissions of each process module to obtain the total carbon footprint of the composite insulator.

[0024] In this embodiment, summarization refers to adding up the carbon emissions of each process module to obtain the total carbon emissions of the composite insulator throughout its entire life cycle from raw materials to finished product, i.e., the total carbon footprint.

Then, by adding the carbon emissions of each module, the total carbon footprint of the composite insulator is: 263 kg CO2 + 180 kg CO2 + 220 kg CO2 + 350 kg CO2 + 150 kg CO2 = 1163 kg CO2.

[0026] In one exemplary embodiment of the present invention, the production process information includes information on five stages: raw material transportation, fitting manufacturing, mandrel manufacturing, compound rubber manufacturing, and injection molding. The multiple process modules include the five process modules of raw material transportation, fitting manufacturing, mandrel manufacturing, compound rubber manufacturing, and injection molding.

[0027] In this embodiment, the production process information of the composite insulator includes at least five stages: raw material transportation, fitting manufacturing, core rod manufacturing, compound rubber manufacturing, and injection molding. Correspondingly, the multiple process modules obtained based on this process information include at least a raw material transportation module, a fitting manufacturing module, a core rod manufacturing module, a compound rubber manufacturing module, and an injection molding module.

[0028] This embodiment uses five process modules—raw material transportation, fitting manufacturing, core rod manufacturing, compounding, and injection molding—as accounting units. It breaks down the carbon emissions of the entire composite insulator process from raw material entry to finished product exit into independent carbon emissions for each process module. Compared to traditional full-process average estimation methods, this application can accurately pinpoint the specific sources of carbon emissions in the production process, avoiding the shortcomings of traditional methods that cannot distinguish the carbon emission contributions of each stage and where errors accumulate and amplify with the process. This significantly improves the accuracy and traceability of carbon footprint accounting results.
