Description:The provisions of this standard for power plants and substations in power transformer, power plants and transformer substation for private use and guide for the selection of distribution transformer. This standard applies to design department to design power plants and transformer substation in selection. The user to place an order for the transformer, can refer to this guideline to determine transformer technology parameters and the content of the contract.
this standard instead of gb/t 17468-1998, compared with the main changes are as follows:
a) written format According to gb/t 1.1 2000 "standardization guide, part 1: the structure of the standard and write rules" provisions into the
the changes;
b) normative reference file supplemented the gb 20052 three-phase distribution transformers in the limited value of energy efficiency and energy conservation value, dl/t 985 distribution transformer technical and economic evaluation of energy efficiency, jb/t 10317 single phase oil-immersed distribution transformer technical parameters and requirements , jb/t 10318 amorphous alloy iron core oil-immersed distribution transformer and some technical parameters and the required standards transformer component standards;
c) transformer of the special conditions of use for the modification and supplement;
d) in the type of transformer, revised according to pressure regulating methods of classifying transformer and cooling way content;
e) of oil-immersed transformer is recommended according to the rated capacity to choose cooling way;
f) Delete the original standard table 3, the dry type transformer temperature limit satisfy the requirements of dry type transformer load standard;
g) increased demand for relevant transformer components;
h) to delete the original standard appendix c, appendix e and appendix g, other appendices number order change;
I) modified the original standard appendix b, increased about cooling way, insulation level, regulating mode, etc;
modified the original standard appendix j) F the bushing current transformers rated primary current standard; Increases the measuring casing type current transformer accuracy level; Modified the protective sleeve type current transformer accuracy limit factor standard; Modified the bushing current transformer recommended performance parameters of the ratings.
