Foreword
This revised standard adopts IEC 62155.2003 "rated voltages higher than 1000V electrical equipment with pressurized and non-pressurized hollow porcelain and glass
Glass insulator "(in English).
This standard and IEC 62155.2003 as compared to doing some technical modifications, modifications at a single vertical line (|) in Chapter they involved
Identification of the margin and added to Appendix E to illustrate these changes and their causes.
For ease of use, this standard made the following editorial changes.
"." --- With a decimal point instead of a comma as the decimal point, "";
--- Remove IEC 62155.2003 Foreword;
--- "This International Standard" be replaced by "this standard";
--- Canceled IEC 62155.2003 bibliography.
The Rules for drafting standards by GB/T 1.1-2000, text structure and IEC 62155.2003 are identical.
Appendix F gives this standard and IEC 62155.2003 clauses table.
The Standard Appendix A, Appendix B, Appendix C, Appendix D, Appendix E and F are informative appendices.
The standard proposed by China Electrical Equipment Industrial Association.
This standard by the National Standardization Technical Committee Insulators (SAC/TC80) centralized.
This standard is mainly drafted by. Xi'an Institute of Electric Porcelain Co., Ltd., West An Shuangjia high-voltage ceramic Electric Co., Ltd., Hunan Liling Huaxin
Porcelain Electric Co., the National Insulator arrester Quality Supervision and Inspection Center, Xi'an High Voltage Apparatus Research Institute Co., Ltd., Chongqing

This standard was first formulated.
1000 Vp higher than the rated voltage electrical equipment under pressure
And non-pressure hollow porcelain and glass insulators
1 Scope and purpose
1.1 General
This standard applies to.
--- Electrical equipment in general-purpose hollow porcelain and glass insulators;
--- Switch and gas pressure control equipment and long-term bear hollow porcelain insulators.
These insulators for AC rated voltage less than 1000V, frequency no greater than 100Hz or DC rated voltage not less than 1500V
Indoor and outdoor electrical equipment.
Hollow insulators suitable electrical equipment for example as follows.
---breaker;
--- Isolation switch;
--- Load switch;
--- Grounding switch;
--- Transformers;
---lightning arrester;
---casing;
--- Cable terminal;
--- Capacitors.
This standard does not specify electrical type tests, it is because a part of the insulator is composed of electrical equipment, withstand voltage is not absolutely hollow
Edge sub own characteristics, but the characteristics of the device.
1.2 general-purpose hollow insulators or hollow insulating member
Hollow glass or porcelain insulators or insulating parts applicable to.
--- Not under pressure;
--- Long withstand internal pressure ≤50kPa (gauge pressure);
--- Long withstand internal gas pressure> 50kPa (gauge pressure), but the lumen volume < 1L (1000cm3);
--- Long withstand the internal pressure of the liquid.
The purpose of this standard are.
--- Definitions of the terms used;
--- Define hollow insulators and mechanical and dimensional characteristics of the hollow insulating member;
--- Define the hollow insulator wall electric strength;
--- Define the characteristic values \u200b\u200bspecified test conditions;
--- Specified test methods;
--- Specified acceptance criteria.
1.3 long withstand the gas pressure within the hollow porcelain insulators
Hollow porcelain insulators or insulating parts long withstand the internal gas pressure, and with the end fitting, long-term internal gas pressure > 50kPa (Table
Pressure), while the cavity volume ≥1L (1000cm3).
NOTE. The gas may be dry air, an inert gas such as nitrogen or sulfur hexafluoride gas, or a mixture of such gases.
