标准范围

IEC 60953-0:20 22构成技术修订。与上一版相比，此版本包括以下重大技术变更:a)IEC 60953-2:19 90已被用作开发IEC 60953-0的基础；b)已更新过时的测量技术，并表明预期测试结果测量不确定度相应降低；c)包括在指定蒸汽流量下的功率输出保证；d)已包括一项分配不明泄漏的提案；e)修正方法和保证比较得到更新；f)删除的各种附录:-附录B（流量喷嘴）-附录E（广义校正曲线）-附录G（功率测量不确定度）g）增加附件:-从IEC 60953接管的附录E（温度变化法）-3:20 02，附件L本文件中给出的规则适用于涵盖各种类型、额定值和应用的汽轮机的各种精度的热验收试验。只有这些规则的相关部分适用于任何个案。这些规则规定了涡轮机的测试，无论是在过热蒸汽还是饱和蒸汽下运行。它们包括确定湿度区域内比焓所需的测量和程序，并描述了在遵守核电站放射性安全规则的同时允许测试所需的预防措施。本标准规定了验收试验的准备、实施、评定、与保证的比较和测量不确定度计算的统一规则。包括可以进行验收测试的条件的细节。如果出现本规则未涵盖的任何复杂或特殊情况，制造商和买方应在签订合同前达成适当的协议。第一版取消并取代了1990年出版的IEC 60953-2。

IEC 60953-0:2022 constitutes a technical revision.This edition includes the following significant technical changes with respect to the previous edition:
a) IEC 60953-2:1990 has been used as the basis to develop IEC 60953-0;
b) Outdated measuring techniques have been updated and the corresponding reduction of the expected test result measuring uncertainty indicated;
c) Guarantee of power output at specified steam flow has been included;
d) A proposal for assignment of unaccounted for leakages has been included;
e) Correction methods and guarantee comparisons are updated;
f) Various appendices deleted:
- Appendix B (flow nozzle)
- Appendix E (generalized correction curves)
- Appendix G (power measurement uncertainty)
g) Annex added:
- Annex E (Temperature variation method) taken over from IEC 60953-3:2002,Annex L
The rules given in this document are applicable to thermal acceptance tests covering a wide range of accuracy on steam turbines of every type, rating and application. Only the relevant portion of these rules will apply to any individual case.
The rules provide for the testing of turbines, whether operating with either superheated or saturated steam. They include measurements and procedures required to determine specific enthalpy within the moisture region and describe precautions necessary to permit testing while respecting radiological safety rules in nuclear plants.
Uniform rules for the preparation, carrying out, evaluation, comparison with guarantee and calculation of measuring uncertainty of acceptance tests are defined in this standard. Details of the conditions under which the acceptance test can take place are included.
Should any complex or special case arise which is not covered by these rules, appropriate agreement is to be reached by manufacturer and purchaser before the contract is signed.
This first edition cancels and replaces IEC 60953-2, published in 1990.
