Foreword

This standard is identical with IEC 60971. 1989 "Semiconductor convertors converter coupled identification code" (in English). In addition to correct its series Series of errors (in the text with a footnote), the technical content is identical, but the edit format according to the provisions of GB T 1.1 /.

The standard proposed by China Electrical Equipment Industrial Association.

This standard by the National Standardization Technical Committee on Electronic electrodynamic (SAC/TC60) centralized.

1 Scope and purpose

1.1 Scope

This standard applies to the diode and thyristor stack GB/T 3859 included converter device, the converter coupling converter device.

The appropriate part of this standard can also be used for other criteria related to the converter coupling valve device stacks and power electronic conversion device.

1.2 Purpose

The purpose of this standard is to provide a logical system, a set of alphanumeric symbols to identify the device and valve device stacks and most of the main arm the main auxiliary arm (if any) of the join, including all the necessary information being studied coupling structure.

Therefore, this code can replace the graphic links, and insert the stack and means for the overall rating among the code, but also easy converter feature Dissemination of information, communication, storage and reprinting.

Terms and definitions used in this standard, see GB/T 2900.33 and GB/T 3859.

Note. In the current standards (for example, GB/T 3859, etc.), as defined in the list of selected current transformer coupling description and serial number identification. The serial number in the above-identified Registration as a reference only, not as part of a general purpose device or heap and overall rating designations.

2 Normative references

3 Identification code structure

The basic code by the converter coupling an alphanumeric symbols, each symbol represents a characteristic junctions. Typically, there are code 4 to 5, the explanatory note in this chapter, with a character D1 ~ D5, m, n and p represent.

In order to identify the combination of the basic links, the introduction of a character associated with a multiplicity factor k.

Note. In this chapter, the characters D1 ~ D5, k, m, n and p is only used for explanatory notes, which in itself does not mean that any of the features of the current transformer coupling. On behalf of a particular feature Number of characters is given in Chapter 4 to Chapter 7.

3.1 Basic links

3.1.1 Single and Double Shot coupling (see 4.1 and 4.2)

Typically, a single unit or device stack by only a basic link the main arm of the composition. This basic link code is usually four, its shape the formula is.

D1 p D3 D4

among them.

D1 --- coupling form (see 4.1 and 4.2);

p --- Number of pulse wave;
