[0055] The embodiments of the present invention provide a method and system for evaluating the environmental impact of a switch cabinet, which is used to solve the technical problem that the current environmental impact of a switch cabinet mainly considers the natural resources consumed by the switch cabinet during operation, but does not consider the impact of the materials constituting the switch cabinet on the environment, thereby reducing the accuracy of the environmental impact assessment of the switch cabinet.

[0056] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] See also Figure 1 , Figure 1 A flowchart of the steps of a method for evaluating the environmental impact of a switch cabinet provided in Embodiment 1 of the present invention.

[0058] The present invention provides a method for evaluating the environmental impact of a switch cabinet, comprising:

[0059] Step 101, obtaining a data list of each life cycle stage of the switch cabinet;

[0060] In the embodiment of the present invention, a data list of each life cycle stage of the switch cabinet is obtained according to the life cycle assessment method.

[0061] It should be noted that the data in the data list are collected according to the following collection principles and selection principles: Collection principle: Switchgear parts are produced in batches during the manufacturing process. Therefore, in the process of data collection, only the processing technology data of a batch of parts can be collected. The life cycle data of a single part cannot be guaranteed. Therefore, the average energy consumption calculation method can be used; the total energy consumption of manufacturing a batch of parts is divided by the number of parts to obtain the life cycle data of each part; or the total energy consumption of manufacturing a batch of parts is divided by the total mass to obtain the life cycle data of the parts per unit mass. Selection principle: (1) When the weight ratio of various raw materials of the switchgear to the whole is less than 0.1%, and the environmental impact is small, the environmental impact value of the entire switchgear is small, it can be ignored; (2) When the weight ratio of various raw materials of the switchgear to the whole is greater than 0.1%, and it is impossible to track and obtain upstream data, materials with similar chemical composition can be selected to replace the original materials; (3) In addition to the main raw materials and manufacturing processes, the data of auxiliary materials and recyclable materials used in each life cycle stage of the switchgear must also be calculated.

[0062] Step 102: extract information from the data list of each life cycle stage according to the life cycle stage to obtain the stage evaluation parameters corresponding to each data list;

[0063] In the embodiment of the present invention, refer to Figure 2 As shown, the life cycle of the switchgear includes the raw material acquisition stage, the manufacturing stage, the waste disposal stage, the use stage and the transportation stage. When the life cycle stage is the raw material acquisition stage, the material parameters of the data list are extracted as the stage evaluation parameters. When the life cycle stage is the manufacturing stage, the component parameters of the data list are extracted as the stage evaluation parameters. When the life cycle stage is the waste disposal stage, the recycling parameters of the data list are extracted as the stage evaluation parameters. When the life cycle stage is the use stage, the energy consumption parameters of the data list are extracted as the stage evaluation parameters. When the life cycle stage is the transportation stage, the transportation parameters of the data list are extracted as the stage evaluation parameters.

[0064] Step 103: using each stage assessment parameter to perform environmental impact assessment on the life cycle stage associated with each stage assessment parameter, to obtain an environmental impact value corresponding to each life cycle stage;

[0065] In the embodiment of the present invention, an environmental impact assessment is performed on each life cycle stage of the switch cabinet according to the stage assessment parameters of each life cycle stage to obtain an environmental impact value corresponding to each life cycle stage.

[0066] Step 104: Perform a sum calculation based on each environmental impact value to obtain an environmental impact assessment value corresponding to the switch cabinet.

[0067] In the embodiment of the present invention, each environmental impact value is dimensionlessly converted and summed to obtain the environmental impact assessment value corresponding to the switch cabinet.

[0068] In an embodiment of the present invention, the present invention obtains a data list of each life cycle stage of the switch cabinet, and extracts information from each data list according to the life cycle stage, thereby solving the environmental impact value of each stage, and then summing up each environmental impact value to obtain the corresponding environmental impact assessment value of the switch cabinet. This overcomes the problem that the environmental impact of the existing switch cabinet mainly considers the natural resources consumed by the switch cabinet during operation, but does not consider the impact of the materials that make up the switch cabinet on the environment, thereby reducing the accuracy of the environmental impact assessment of the switch cabinet. Compared with traditional environmental assessment methods, the present invention comprehensively considers the impact of multiple life cycle stage factors on the environment, thereby improving the accuracy of the environmental impact assessment of the switch cabinet.
