GB/T 26869-2011Insulator-test on indoor post insulator of organic material for systems with nominal voltages greater than 1 000 V up to but not including 300 kV (English PDF)

Foreword

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

This standard uses redrafted law revision adopted IEC 60660:1999 "nominal voltage above 1000V below the 300kV system users within Post insulators of organic material "(English version).

This standard and IEC 60660:1999 in the structure compared to, in addition to increasing the "References", the other are the same.

This standard and IEC 60660:1999 technical differences and the reasons are as follows.

--- On normative references, this standard has been adjusted technical differences, in order to adapt our technical conditions, the adjusted situation Situation is reflected in the 1.2 "Normative references", the specific adjustments are as follows.

- non-equivalent (neq) the adoption of international standards of GB 311.1 instead of IEC 60071-1 (see 1.1);

- equivalents adoption of international standards GB/T 2900.8 instead of IEC 60050-471 (see 1.3);

- equivalents adoption of international standards GB/T 5169.16 instead of IEC 60695-11-10 (see 3.12);

- equivalents adoption of international standards GB/T 7354 instead of IEC 60270 (see 3.5,5.4);

- Modify with international standards of GB/T 8287.2 instead of IEC 60273 (see 1.1);

- use equivalent to international standards of GB/T 16927.1 replaced by IEC 60060-1 (see 2.3 to 2.7,3.3,3.4);

- increased references GB 3906 (IEC 60932. 1988 as the content included in Appendix C GB 3906-2006, see 3.11);

- Remove the IEC 60660:1999 references IEC 60932 (see IEC 60660:1999 1.2 and 3.11).

--- Added "mechanical type test report is valid for 10 years, long-term effective electrical type test", which is based 2.1a) in China's actual situation and with reference to the relevant standard porcelain and glass insulators added.

--- Increased in 4.3 "If we can clearly identify the cause of product failure, producing the insulator can be excluded in this batch have all insulators "This defect, so repeating the test program further examination to implement more explicit.

This standard made the following editorial changes.

--- Use the "standard" instead of "this International Standard";

--- With a decimal symbol instead of the symbol ",". ",";

--- The first stage will be changed to the lettered column items in a numbered;

--- The suspension of 3.5,3.7 segment added two section heading, section heading and the subsequent two extended;

--- The suspension of 3.6,3.12 paragraph to note;

--- Delete foreword international standards;

--- Added "References." Note. IEC 60660:1999 1.2 "Normative references" in the IEC 60587 and ISO 9000-1, ISO 9002 (now part of both ISO standards ISO 9001) in the provisions of the document are referred to in footnote, it is informative references. According to GB/T 1.1-2009 provides informative references should Included in the "Normative references", and can be included in the "References." Increased "References" lists the correspondence between its consistency of standard.

The standard proposed by China Electrical Equipment Industrial Association.

This standard by the National Standardization Technical Committee Insulators (SAC/TC80) centralized.

This standard was drafted. Xi'an High Voltage Apparatus Research Institute Co., Ltd., New Northeast (Shenyang) High Voltage Switchgear Co., Ltd.
