Introduction
The electrical equipment of rolling stock is an important part of rolling stock: Its function and performance directly affect the performance and safety of the entire vehicle:
Reliable operation is to standardize the design, manufacturing, inspection and storage of rolling stock electrical equipment and the key electrical components used:
According to the requirements, GB/T 21413 "Electrical Equipment for Rail Transit Rolling Stocks" was specially formulated: This series of documents comprehensively covers the electrical equipment of rolling stock:
General requirements and special requirements for key electrical components to guide the design units, inspection and testing of electrical equipment and electrical components for rolling stock in my country:
Units and operating units carry out relevant work in a scientific manner:
GB/T 21413 is planned to consist of five parts:
---Part 1: General conditions of use and general rules: The purpose is to standardize as much as possible common features in rolling stock electrical equipment
rules and requirements to achieve consistency in equipment requirements and testing:
---Part 2: General rules for electrical devices: The purpose is to apply the general conditions specified in Part 1 to rolling stock
All electrical devices to ensure the consistency of the technical requirements and testing 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 equipment
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
requirements, work performance requirements and inspection requirements:
Rail transit rolling stock electrical equipment
Part 5: Rules for high-voltage fuses for electrical equipment
1 Scope
Based on the general rules of GB/T 21413:2-2021, this document specifies additional or modified rules for high-voltage fuses:
Note 1: In this document, the term "high voltage fuse" refers to fuses used in the voltage range of rail transit rolling stock:
High-voltage fuses specified in this document refer to high-voltage fuses connected to the main circuit and/or auxiliary circuit: According to IEC 60850
A certain range, the nominal voltage range of these circuits is DC600V~DC3000V: These fuses are also available in the nominal voltage range
In the AC auxiliary circuit of 0V~1500V:
Note 2: If necessary, certain rules may be applied to fuses installed on other rolling stock (such as mining locomotives, trolleybuses, etc:):
This document applies to high-voltage fuses on rolling stock:
This document together with GB/T 21413:2-2021 gives the following content:
---Fuse characteristics;
---The fuse should meet:
● Working performance under normal conditions;
● Working performance under short circuit conditions;
● Dielectric properties:
---Test items and test methods used to verify that the fuse meets the characteristics under usage conditions;
---The mark or information given on the fuse:
This document does not apply to parallel connections of fuses:
This document fully takes into account GB/T 13539:1-2015 and GB/T 15166:2-2008:
This document refers to the general rules for electrical devices specified in GB/T 21413:2-2021, but the general conditions of use refer directly to
GB/T 21413:1-2018:
