The key parameters of the state are used as the criterion for circuit resistance measurement;

---Deleted the noise-related requirements (see 8.2:5, 9:3:7, Table 3 of IEC 60077-4:2019), because the noise test is in IEC 60077-4 is optional, and in actual applications in my country, the background noise when the circuit breaker is working is much higher than the circuit breaker itself:

noise;

--- Added functional requirements (see 9.2) as a criterion for functional verification;

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 can guide the design units and inspection units of my country's rolling stock electrical equipment and their electrical components:

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 are required 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 equipment requirements, work performance requirements and inspection requirements:

1 Scope

Based on the general rules of GB/T 21413.2-2021, this document specifies the communication between the main contact and the AC overhead contact network:

The rules for the use of current circuit breakers and the nominal voltage of the circuit comply with the requirements of IEC 60850:

This document applies to AC circuit breakers on rolling stock:

This document gives the following content together with GB/T 21413.2-2021:

---Circuit breaker characteristics:

---The circuit breaker 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 device meets the characteristics under usage conditions:

---The information that should be marked or given on the circuit breaker:

Note 1: The circuit breaker described in this document is equipped with a device that can automatically break under predetermined conditions excluding overcurrent (such as undervoltage, reverse current, etc:), but this document the document does not provide a method for verifying operation under this condition:

Note 2: Nowadays, electronic devices and components are usually classified as electrical devices: This document does not apply to electronic devices, but this document also applies to electronic devices equipped with installed electrical equipment:

This document only specifies the special requirements to ensure the normal operation of AC circuit breakers on rolling stock: This document does not apply to industrial circuit breakers the relevant requirements for industrial circuit breakers are specified in IEC 62271-100:2021: To this end, specific documents will be used to stipulate industrial circuit breakers:

Circuit breakers should meet additional requirements such as:

---Applicable working conditions (such as control voltage, environmental conditions, etc:);

---Installation and use that do not need to withstand specific rolling stock usage conditions;

---Additional tests to prove that the device can withstand rolling stock conditions:
