GB/T 3859.3-2013Semiconductor converters -- General requirements and line commutated converters -- Part 1-3: Transformers and reactors (English PDF)

Foreword

GB/T 3859 "Semiconductor convertors" is divided into the following sections.

--- Part 1-1. Specification of basic requirements

--- Part 1-2. Application guide

--- Part 1-3. Transformers and reactors

--- Part 2. including direct dc converters semiconductor self commutated converter this section Part 1-3 GB/T 3859's.

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

This Part replaces GB/T 3859.3-1993 "semiconductor converter transformers and reactors." this section compared with the GB/T 3859.3-1993, the main technical changes are as follows.

--- Modify the standard name, the international standard IEC 60146-1-3 adopted. Consistent 1991 name;

--- Modify the "scope" (see Chapter 1, Chapter 1, 1993 edition);

--- Adjustment of the "standards" (see Chapter 2, Chapter 2, 1993 edition);

--- Revised 1993 edition of the suspension segment prior to 5.1, and adjusted to "5.1 Overview", Chapter 5 in the rest of the article renumbered (see Chapter 5, Chapter 5, 1993 edition);

--- No. adjusted Table 1 and Table 2;

--- Increasing the temperature class F and the corresponding temperature rise limits (see Table 2);

--- Added "At altitudes above 1000m, shall amend the relevant standard" requirement (see 5.4).

This section uses redrafted law revision adopted IEC 60146-1-3:1991 "Semiconductor convertors - General requirements and line-commutated converter Part 1-3. Transformers and reactors. " this part of IEC 60146-1-3:1991 and its technical differences for the following reasons.

--- According to the standardization of the rules, revised the "scope" (see Chapter 1);

--- According to the standard provisions of the actual citations, adjusted some normative references (see Chapter 2);

--- Deleted the paragraph 3.2 of the suspension. "The temperature rise limit specified in 5.3."

--- Revised Table 1, thereby GB/T 3859.2-2013 appropriate consistent with Table 1;

--- Deleted Table 2 Column 2 Limits and Note 1, Note 4, which is consistent with the relevant provisions of the standard transformer;

--- Increasing the temperature class F and the corresponding temperature rise limits (see Table 2);

--- Added "At altitudes above 1000m, shall amend the relevant standard" requirement (see 5.4).

This part made the following editorial changes. Corrected number 5.1.2,5.3 respective segment and 5.4 expressed in Tables 1 and 2.

This part is proposed by the China Electrical Equipment Industrial Association.

This part of the National Science Power Electronics Standardization Technical Committee (SAC/TC60) centralized.

1 Scope

GB/T 3859 provisions of this part of the converter transformer power transformer is different from the general characteristics.

It should be noted, rectifier transformer operation, it is usually a non-sinusoidal currents circulate. In a single shot coupling, the current winding are each valve Containing the DC component, special attention should be designed and tested. In some cases, short circuit and external component failure cause abnormal stress, Thus the need for special design.

Some types of non-sinusoidal waveform voltage transformer normal operation. Its core loss as to have a voltage half cycle and run-time and the fundamental frequency is equal to the arithmetic average of the sine wave voltage is determined.

This section applies to GB/T 3859.1 prescribed power converter equipment supporting the use of converter transformers and reactors. In other all aspects, if national standards "power transformer" and this section does not conflict with the provisions of the rule also applies to the converter transformer.
