GB/T 32347.2-2015Railway applications -- Environmental conditions for equipment -- Part 2: Fixed electrical installations (English PDF)

Foreword

GB/T 32347 "rail transportation equipment, environmental conditions," is divided into three parts.

--- Part 1. rolling stock equipment;

--- Part 2. ground electrical equipment;

--- Part 3. Signal and communications equipment.

This section GB/T Part of 232,347.

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

This section uses redrafted law revision using IEC 62498-2:2010 "rail transportation equipment, environmental conditions - Part 2. Electric Ground Gas equipment. " this part of IEC 62498-2:2010 compared to the existence of technical differences, these differences involve the provision of a single vertical line in the margin (-) Were marked. This part of IEC 62498-2:2010 compared to the existence of technical differences and their reasons are as follows.

--- Situation on normative references, this part of the technical differences have been adjusted in order to adapt to China's technical conditions, adjustment Focus reflected in Chapter 2, "Normative references" on. Specific adjustments are as follows.

- Modify with international standards of GB/T 4797.1 instead of IEC 60721-2-1. 1982 (see 4.3.1);

- increase of GB 50009-2012 (see 4.4.1 and 4.7.2);

- increase the GB 50178 (see 4.8);

- Remove the IEC 60529, informative annex to cite references and instead GB 4208 (see B.8).

--- Remove some of the terms, the related terms in 11804-2005 GB/T has been defined (see IEC 62498-2. 3.3 2010's ~ 3.5);

--- Modify the elevation requirements to meet our requirements for traction equipment elevation (see 4.2, IEC 62498-2:2010 4.2);

--- Increase the bioactive material needs to take into account the necessary termite protection (see 4.10).

This section also made the following editorial changes.

--- Modify the formula (1) indicates the gain IEC 62498-2. B.3 2010 on the domestic terrain roughness coefficient provisions;

--- Remove the IEC 62498-2:2010 Chinese Appendix B (1), and 4.4.1 of the formula (1) is repeated;

--- Remove the IEC 62498-2. B.2 2010, without reference to Japan's argument;

--- Remove the IEC 62498-2. B.3 2010, relevant content was adjusted to 4.4.1;

--- Modify the IEC 62498-1. Appendix A and Appendix B of the order of 2010 to comply with the revised text of the order;

--- Revised reference.
