Reliable operation, in order to standardize the design, manufacture, inspection and storage of the electrical equipment of rolling stock and its key electrical components:

Therefore, GB/T 21413 "Electrical Equipment of Rail Transit Locomotive and Rolling Stock" is specially formulated, which comprehensively covers the general requirements for electrical equipment of rolling stock and

and the special requirements for key electrical components, which can guide the design units, inspection units and operators of electrical equipment and electrical components of locomotives and vehicles in my country:

The unit scientifically carries out related work: GB/T 21413 consists of five parts:

--- Part 1: General conditions of use and general rules: The purpose is to standardize the commonalities in the electrical equipment of rolling stock as much as possible

rules and requirements to achieve consistency with equipment requirements and tests:

--- Part 2: General rules for electrical devices: The purpose is to apply the general conditions set out in Part 1 to rolling stock

To ensure the consistency of the technical requirements and tests of the corresponding devices:

--- Part 3: Rules for DC circuit breakers for electrical devices: The purpose is to standardize the basic characteristics of DC circuit breakers in electrical devices

requirements, work performance requirements and inspection requirements:

--- Part 4: Rules for AC circuit breakers for electrical devices: The purpose is to standardize the basic characteristics of AC circuit breakers in electrical devices

requirements, work performance requirements and inspection requirements:

--- Part 5: Rules for high-voltage fuses for electrical devices: The purpose is to standardize the basic characteristics of high-voltage fuses in electrical devices

Rail transit locomotive and rolling stock electrical equipment

Part 2: General rules for electrotechnical devices

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:
