Life cycle assessment method of transformer products
1 Scope
This standard specifies the life cycle assessment and life cycle report of transformer products.
This standard applies to the life cycle assessment of transformer products, and transformer products make type Ⅲ ring based on GB/T 24025-2009
Environment statement.
Note. According to GB/T 24025-2009, this standard is the product category rule for transformer products to carry out Type Ⅲ environmental declaration. When carrying out Type Ⅲ environmental declaration, use
The use of product category rules helps to ensure the credibility and comparability of life cycle assessment conclusions.
This standard applies to the power transformers specified in GB/T 1094.1, including transformers (final products) and operating transformers directly supplied to end users.
Transformers (intermediate products) that are part of the equipment. Other similar transformer products can also be used as reference.

Note 2.The reference life is also called the "typical life", which is a theoretical period for calculation purposes. It may be different from the shortest, average or actual life of the product.
[GB/T 37552-2019, definition 3.14]
4 Product life cycle assessment
4.1 Product description
The product description should enable users to clearly identify the product, such as.
a) Product name;
b) The model, specification or dimensions of the product;
c) Parameters related to product weight;
d) The main technical parameters and performance of the product;
e) The relevant quality standards that the product meets;
f) Other marks obtained by the product, etc.
It can be described with reference to the requirements of relevant transformer standards.
4.2 Scope of life cycle assessment
4.2.1 Functional unit
This standard takes "1 transformer" as the functional unit, and the description of the functional unit shall include, but is not limited to.
a) The function of the product (that is, the service to the user);
b) Rated capacity;
c) Rated voltage;
d) Rated frequency;
e) number of phases;
f) Cooling method;
g) Reference life (design life).
Note. 1 three-phase dry-type distribution transformer with rated capacity of 315kVA, rated voltage of 10/0.4kV, rated frequency of 50Hz, cooling method AN/AF,
The reference life span is 20 years.
The benchmark flow of the corresponding functional unit includes.
a) A benchmark product that realizes the functions described in the functional unit;
b) Materials that do not appear in the benchmark product, for example, materials that are lost during the manufacturing stage;
c) Base product packaging;
d) Necessary products used in the installation of the benchmark product.
4.2.2 System boundary
4.2 of GB/T 37552-2019 applies to this standard. See Figure 1 for details.
For the transformer as the final product, a full life cycle assessment should be carried out; for the transformer as an intermediate product, partial production can be carried out.

4.3 Data collection
4.3.1 Default scenario
4.3.1.1 General requirements
4.3.1 of GB/T 37552-2019 applies to this standard. In addition, this standard addresses the defaults in the use phase and the end-of-life phase.
The recognition scenario puts forward specific requirements.
4.3.1.2 Use stage
4.3.1.2.1 Energy consumption calculation
The energy consumption of the transformer in the use phase of the reference life can be calculated with reference to equations (1) to (5).
The above parameters should be determined according to the specific conditions of the product. Examples are as follows.
When taking the minimum load of the 6kV~10kV step-down transformer used in urban power grids and industrial enterprise power grids, its reactive power equivalent
KQ=0.1kW/kvar; the annual average load rate of transformers, for agricultural transformers, β=20% may be adopted; for industrial enterprises that implement three shifts
For industry, the desirable β=75%; P0, PK, I0%, UK% see product information.

The following processing links should be considered for all elements of the life cycle and recorded in the life cycle assessment report.
a) Product/material disposal process (energy recovery, landfill);
b) Product/material recycling (reuse, recycling or energy recovery).
If the data for end-of-life processing is not available, the transportation of end-of-life waste and the types of waste materials should be considered.

For the transformer manufacturing stage, it is advisable to collect field data of benchmark products as much as possible. When the field data of the benchmark product cannot be determined
Next, if the main materials and functions of the product are similar, the data can be allocated according to key factors such as the rated capacity of the product.
4.4 Environmental impact indicators
The life cycle assessment report of the transformer should include at least the “Global Warming Potential” in Table A.1 of GB/T 37552-2019
(GlobalWarmingPotential, GWP)" and "Abiotic Depletion Potential (ADP)" etc.
