Full title and description

GOST 33726-2016 — Static non-tractive converters for railway rolling stock. General specifications (Russian: Преобразователи статические нетяговые для железнодорожного подвижного состава. Общие технические условия). The standard defines general technical requirements, test and acceptance rules, safety and EMC requirements, and guidance for operation, packaging and marking of static non-tractive power converters used on railway rolling stock.

Abstract

This national (interstate) standard sets out terms and definitions, technical requirements (including reliability, construction, functional behaviour, electrical safety, fire safety, environmental and EMC resistance), methods of control and testing, acceptance rules, and provisions for packaging, transportation, storage and manufacturer's guarantees for static non-tractive converters intended for use on railway rolling stock. It is aimed at ensuring safety, interoperability and conformity of non-tractive power-conversion equipment in railway applications.

Scope

The standard applies to static non-tractive converters (power electronic units that are not used for traction drive but supply auxiliary and service systems) installed on railway rolling stock. It covers design and construction aspects, reliability and functional requirements, electrical safety and protection, electromagnetic compatibility, environmental resistance, fire safety, marking, acceptance testing, inspection methods, and instructions for packaging, transport, storage and operation. The scope excludes traction converters intended for traction drive systems.

Key topics and requirements

• Definitions and classification of static non-tractive converters (types and intended functions).
• General technical and reliability requirements (service life, maintainability, failure rates and reliability tests).
• Construction and completeness requirements (mechanical layout, enclosure ratings, protection levels).
• Functional requirements (voltage/current stabilization, frequency stabilization, charging functions where applicable).
• Electrical safety and protection against electric shock (aligned with IEC/Russian protective standards).
• Electromagnetic compatibility (EMC) and immunity/resistance to external disturbances.
• Fire safety, environmental and climatic resistance (climatic categories and IP degrees of protection).
• Acceptance rules and test methods (type tests, routine tests, reliability and EMC testing procedures).
• Marking, packaging, transportation, storage, operational instructions and manufacturer's guarantees.

Typical use and users

Manufacturers and designers of railway auxiliary power equipment, rolling stock builders, railway operators and maintenance organizations, conformity assessment and testing laboratories, certification bodies, and regulatory authorities use this standard to design, verify, procure and maintain static non-tractive converters for railway vehicles. It is also used as a normative reference when demonstrating compliance with relevant technical regulations for railway safety.
