GB/T 21413.2-2021Railway applications - Electric equipment for rolling stock - Part 2: Electrotechnical components - General rules (English PDF)

1 Scope

This document specifies the general rules for all electrotechnical devices installed in the main circuit, auxiliary circuit, control circuit and indicating circuit of rolling stock:

rule:

This document applies to all electrical components on rolling stock:

Electrical devices mainly refer to switching equipment and control equipment, including relays, electro-pneumatic (magnetic) valves, resistors, fuses, etc:, regardless of their control:

What is the nature of the system:

At present, electronic components or electronic assemblies are usually incorporated into electrical devices: This document does not apply to electronic equipment, but not because

Electrotechnical devices incorporating electronic components or electronic assemblies are excluded from the scope of this document:

Electronic components or electronic assemblies comply with the corresponding standards:

After consultation between the user and the manufacturer, some rules of this document may be applied to other rolling stock (such as industrial and mining locomotives, trolleybuses, etc:) electrical equipment:

This document gives:

--- Device characteristics;

--- Conditions of use that the device should follow;

--- Test items and test methods used to verify that the device meets the characteristics under the conditions of use;

--- Information should be identified or given on the device:

This document does not apply to industrial electrical devices, which comply with their respective product standards: In order to ensure the normal operation of these devices on the rolling stock work, this document only specifies the special requirements for these devices under rail traffic conditions: For this purpose, these devices will be described by specific documents

Additional requirements that should be met, such as:

--- make adaptations (such as control voltage, environmental conditions, etc:);

--- does not need to withstand the installation and use of specific rolling stock conditions of use;

--- Carry out additional tests to verify that these devices can meet the conditions of rolling stock:

In the event of a discrepancy between the requirements of this document and the rolling stock-related product standards, the product standard requirements shall prevail:
