GB/T 16927.1-2011High-voltage test techniques -- Part 1: General definitions and test requirements (English PDF)

Foreword

GB/T 16927 "High voltage test techniques" is divided into three parts.

--- Part 1. General definitions and test requirements;

--- Part 2. Measuring systems;

--- Part 3. Definition and field test requirements.

This section is GB/T Part of 116,927.

This section drafted in accordance with GB/T 1.1-2009 given rules.

The partial modification using IEC 60060-1:2010 "High voltage test techniques - Part 1. General definitions and test requirements." this part is GB/T 16927.1-1997 "High voltage test techniques - Part 1. General test requirements" amendments.

This portion of the GB/T 16927.1-1997 compared, in addition to editorial changes outside the main technical changes are as follows.

--- Increasing the general definitions and terminology;

--- Remove a detailed description of artificial pollution test and original Appendix B "Artificial pollution test procedures";

--- Removed all of approved measuring device calibration measuring device not recognized terms;

--- Remove the surge current tests related content;

--- Remove the original Appendix C "with a bar - bar clearance check measuring device not recognized";

--- Increasing the normative Appendix B "overshoot or oscillations superimposed on a standard lightning impulse parameter calculation procedure";

--- Increase the informative appendix C "strike test voltage function of the digital filter, for example";

--- Increase the informative Appendix D "function to assess the impact impulse voltage overshoot Background";

--- Increase the informative Appendix E "calculation method was repeated to determine the inverse program when atmospheric correction factor";

--- Of atmospheric correction has been revised (see 4.3);

--- Redefine lightning shock wave through the prescribed limits and calculation methods punch (see Chapter 7);

--- Combined voltage test gives specific provisions (see Chapter 9).

This part of IEC 60060-1:2010 The main differences are as follows.

--- According to the provisions of GB/T 1.1-2009, the standard language of presentation and format has been modified;

--- Remove the preface of international standards, increase the standard of this preface;

--- When calculated parameters g, on the "minimum discharge path" add a description "L GB 311.1 refer to Appendix A" (see 4.3.4.3);

--- Wet test explicitly given outer 800kV equipment and 1100kV wet insulation test procedure proposed recommended equipment (see 4.4);

--- IEC 60060-1 frequency range of 45Hz ~ 65Hz, 60Hz to take into account China's power grid is not applicable, it will be set to the frequency range 45Hz ~ 55Hz, in order to be consistent with GB 311.1 (see 6.2.1.1);

--- Before lightning surge oscillation retention requirements wavefront oscillation maximum allowable value, IEC standard which is not required (see 7.2.2);

--- Increasing the calculation example. oscillogram obtained when the actual test 1100kV breaker as an example calculation (see Appendix B).

This part of IEC 60060-1:2010 clause above main difference has been involved in an empty space by the outside edge of the vertical single page Line (_) were marked.

This Part replaces GB/T 16927.1-1997 "High voltage test techniques - Part 1. General test requirements." this part is proposed by the China Electrical Equipment Industrial Association.

This part of the National high-voltage test technique and insulation with Standardization Technical Committee (SAC/TC163) centralized.

1 Scope

GB/T 16927 provisions of this part of the terms used, producing general requirements for test procedures and test, the test voltage and current Students, test procedures, test results and treatment trials eligibility criteria.

This section applies to a maximum voltage of Um above 1kV following test equipment.

a) DC voltage insulation test;

b) AC voltage insulation test;

c) impulse voltage insulation test;

Joint and combined test d) above voltage.

Note 1. For the field test, see GB/T 16927.3.

Note 2. In order to obtain reproducible results and effective, may require the use of an alternative test procedure. By the relevant Technical Committee selects the appropriate test procedures.

Note 3. Um more than 800kV equipment, to meet some of the provisions of the program, it may not meet the tolerances and uncertainties.
