GB/T 11604-2015Testing procedure of radio interference generated by high voltage equipment (English PDF)

Foreword

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

This standard replaces GB/T 11604-1989 "high-voltage electrical equipment radio interference testing methods." This standard and GB/T 11604-Compared to 1989, in addition to editorial changes outside the main technical changes are as follows.

--- Radio interference voltage increases, the term describes the rated voltage;

--- Chapter reprogramming, and the techniques and the experimental loop have clearly described in more detail;

--- State of the sample gives a clear definition of description (see 4.2);

--- Test area gives specific requirements (see 4.3);

--- On the atmospheric conditions of temperature, pressure and humidity range be revised, given the high altitude of the altitude correction requirements (see 4.4);

--- The reference test frequency recommended values \u200b\u200bgiven in our laboratory 1MHz (see 4.5);

--- Increased content measuring instruments (see 4.6);

--- Radio interference AC electrical test equipment in the circuit layout, installation and test validation checking arrangement, loop, loop calibrator, Additional monitoring period and so give a detailed description (see Chapter 5);

--- Increasing the DC electrical equipment radio interference test content (see Chapter 6);

--- Increase A "standard CISPR quasi-peak measuring instrument for receiving AC corona noise response" Appendix informative;

--- Increase the informative Appendix B "differs from the basic standard instrument CISPR radio interference measuring apparatus";

--- Increase the informative appendix C "DC radio interference phenomenon described." this standard uses the redrafted law revision using IEC/T RCISPR18-2.2010 Radio interference "of overhead lines and high-voltage equipment Characteristics - Part 2. Measurement methods and procedures to determine the limits. " The Standard and IEC/T RCISPR18-2.2010 and technical differences the following reasons.

--- Reference of this standard IEC/T RCISPR18-2. Section 20104.5 "radio interference measuring laboratory of high voltage equipment" content Modify other sections not involved;

--- Radio interference voltage increases, the term describes the rated voltage;

--- On the atmospheric conditions of temperature, pressure and humidity range be revised, given the high altitude of the altitude correction requirements (see 4.4);

--- The reference test frequency recommended values \u200b\u200bgiven in our laboratory 1MHz (see 4.5);

--- Increasing the DC electrical equipment radio interference test content (see Chapter 6).
